 ### How to Contribute

-#### Ask questions
+#### Discuss

-If you have a question, check Stack Overflow using
-[this list of tags](https://stackoverflow.com/questions/tagged/spring+or+spring-mvc+or+spring-aop+or+spring-jdbc+or+spring-transactions+or+spring-annotations+or+spring-jms+or+spring-el+or+spring-test+or+spring+or+spring-remoting+or+spring-orm+or+spring-jmx+or+spring-cache+or+spring-webflux?tab=Newest). Find an existing discussion, or start a new one if necessary.
+If you have a question, check StackOverflow using
+[this list of tags](https://spring.io/questions), organized by Spring project.
+Find an existing discussion or start a new one if necessary.

-If you believe there is an issue, search through
-[existing issues](https://github.com/spring-projects/spring-framework/issues) trying a
-few different ways to find discussions, past or current, that are related to the issue.
-Reading those discussions helps you to learn about the issue, and helps us to make a
-decision.
+If you suspect an issue, perform a search in the
+[JIRA issue tracker](https://jira.spring.io/browse/SPR), using a few different keywords.
+When you find related issues and discussions, prior or current, it helps you to learn and
+it helps us to make a decision.

-#### Create an Issue
+#### Create a Ticket

 Reporting an issue or making a feature request is a great way to contribute. Your feedback
-and the conversations that result from it provide a continuous flow of ideas. However,
-before creating a ticket, please take the time to [ask and research](#ask-questions) first.
+and the conversations that result from it provide a continuous flow of ideas. 

-If you create an issue after a discussion on Stack Overflow, please provide a description
-in the issue instead of simply referring to Stack Overflow. The issue tracker is an
-important place of record for design discussions and should be self-sufficient.
+Before you create a ticket, please take the time to [research first](#discuss).

-Once you're ready, create an issue on [GitHub](https://github.com/spring-projects/spring-framework/issues).
+If creating a ticket after a discussion on StackOverflow, please provide a self-sufficient description in the ticket, independent of the details on StackOverview. We understand this is extra work but the issue tracker is an important place of record for design discussions and decisions that can often be referenced long after the fix version, for example to revisit decisions, to understand the origin of a feature, and so on.

-Many issues are caused by subtle behavior, typos, and unintended configuration.
-Creating a [Minimal Reproducible Example](https://stackoverflow.com/help/minimal-reproducible-example)
-(starting with https://start.spring.io for example) of the problem helps the team
-quickly triage your issue and get to the core of the problem.
+When ready create a ticket in the [JIRA issue tracker](https://jira.spring.io/browse/SPR).

-#### Issue Lifecycle
+#### Ticket Lifecycle

-When an issue is first created, it is flagged `waiting-for-triage` waiting for a team
-member to triage it. Once the issue has been reviewed, the team may ask for further
-information if needed, and based on the findings, the issue is either assigned a target
-milestone or is closed with a specific status.
+When an issue is first created, it may not be assigned and will not have a fix version.
+Within a day or two, the issue is assigned to a specific committer and the target
+version is set to "Waiting for Triage". The committer will then review the issue, ask for
+further information if needed, and based on the findings, the issue is either assigned a fix
+version or rejected.

-When a fix is ready, the issue is closed and may still be re-opened until the fix is
-released. After that the issue will typically no longer be reopened. In rare cases if the
-issue was not at all fixed, the issue may be re-opened. In most cases however any
-follow-up reports will need to be created as new issues with a fresh description.
+When a fix is ready, the issue is marked "Resolved" and may still be re-opened. Once a fix
+is released, the issue is permanently "Closed". If necessary, you will need to create a new,
+related ticket with a fresh description.

 #### Submit a Pull Request

+You can contribute a source code change by submitting a pull request.

-# Spring Framework Build
-
-This folder contains the custom plugins and conventions for the Spring Framework build.
-They are declared in the `build.gradle` file in this folder.
-
-## Build Conventions
-
-The `org.springframework.build.conventions` plugin applies all conventions to the Framework build:
-
-* Configuring the Java compiler, see `JavaConventions`
-* Configuring the Kotlin compiler, see `KotlinConventions`
-* Configuring testing in the build with `TestConventions` 
-
-
-## Build Plugins
-
-### Optional dependencies
-
-The `org.springframework.build.optional-dependencies` plugin creates a new `optional`
-Gradle configuration - it adds the dependencies to the project's compile and runtime classpath
-but doesn't affect the classpath of dependent projects.
-This plugin does not provide a `provided` configuration, as the native `compileOnly` and `testCompileOnly`
-configurations are preferred.
-
-### API Diff
-
-This plugin uses the [Gradle JApiCmp](https://github.com/melix/japicmp-gradle-plugin) plugin
-to generate API Diff reports for each Spring Framework module. This plugin is applied once on the root
-project and creates tasks in each framework module. Unlike previous versions of this part of the build,
-there is no need for checking out a specific tag. The plugin will fetch the JARs we want to compare the
-current working version with. You can generate the reports for all modules or a single module:
-
-```
-./gradlew apiDiff -PbaselineVersion=5.1.0.RELEASE
-./gradlew :spring-core:apiDiff -PbaselineVersion=5.1.0.RELEASE
-```      
-
-The reports are located under `build/reports/api-diff/$OLDVERSION_to_$NEWVERSION/`.
-                                                                                       
-
-### RuntimeHints Java Agent
-
-The `spring-core-test` project module contributes the `RuntimeHintsAgent` Java agent.
-
-The `RuntimeHintsAgentPlugin` Gradle plugin creates a dedicated `"runtimeHintsTest"` test task for each project.
-This task will detect and execute [tests tagged](https://junit.org/junit5/docs/current/user-guide/#running-tests-build-gradle)
-with the `"RuntimeHintsTests"` [JUnit tag](https://junit.org/junit5/docs/current/user-guide/#running-tests-tags).
-In the Spring Framework test suite, those are usually annotated with the `@EnabledIfRuntimeHintsAgent` annotation.
-
-By default, the agent will instrument all classes located in the `"org.springframework"` package, as they are loaded.
-The `RuntimeHintsAgentExtension` allows to customize this using a DSL:
-
-```groovy
-// this applies the `RuntimeHintsAgentPlugin` to the project
-plugins {
-	id 'org.springframework.build.runtimehints-agent'
-}
-
-// You can configure the agent to include and exclude packages from the instrumentation process.
-runtimeHintsAgent {
-	includedPackages = ["org.springframework", "io.spring"]
-	excludedPackages = ["org.example"]
-}
-
-dependencies {
-    // to use the test infrastructure, the project should also depend on the "spring-core-test" module
-	testImplementation(project(":spring-core-test"))
-}
-```
-
-With this configuration, `./gradlew runtimeHintsTest` will run all tests instrumented by this java agent.
-The global `./gradlew check` task depends on `runtimeHintsTest`.            
-
-NOTE: the "spring-core-test" module doesn't shade "spring-core" by design, so the agent should never instrument
-code that doesn't have "spring-core" on its classpath.

-== Spring Framework Concourse pipeline
-
-The Spring Framework uses https://concourse-ci.org/[Concourse] for its CI build and other automated tasks.
-The Spring team has a dedicated Concourse instance available at https://ci.spring.io with a build pipeline
-for https://ci.spring.io/teams/spring-framework/pipelines/spring-framework-6.0.x[Spring Framework 6.0.x].
-
-=== Setting up your development environment
-
-If you're part of the Spring Framework project on GitHub, you can get access to CI management features.
-First, you need to go to https://ci.spring.io and install the client CLI for your platform (see bottom right of the screen).
-
-You can then login with the instance using:
-
-[source]
----
-$ fly -t spring login -n spring-framework -c https://ci.spring.io
----
-
-Once logged in, you should get something like:
-
-[source]
----
-$ fly ts
-name                  url                   team                  expiry
-spring                https://ci.spring.io  spring-framework      Wed, 25 Mar 2020 17:45:26 UTC
----
-
-=== Pipeline configuration and structure
-
-The build pipelines are described in `pipeline.yml` file.
-
-This file is listing Concourse resources, i.e. build inputs and outputs such as container images, artifact repositories, source repositories, notification services, etc.
-
-It also describes jobs (a job is a sequence of inputs, tasks and outputs); jobs are organized by groups.
-
-The `pipeline.yml` definition contains `((parameters))` which are loaded from the `parameters.yml` file or from our https://docs.cloudfoundry.org/credhub/[credhub instance].
-
-You'll find in this folder the following resources:
-
-* `pipeline.yml` the build pipeline
-* `parameters.yml` the build parameters used for the pipeline
-* `images/` holds the container images definitions used in this pipeline
-* `scripts/` holds the build scripts that ship within the CI container images
-* `tasks` contains the task definitions used in the main `pipeline.yml`
-
-=== Updating the build pipeline
-
-Updating files on the repository is not enough to update the build pipeline, as changes need to be applied.
-
-The pipeline can be deployed using the following command:
-
-[source]
----
-$ fly -t spring set-pipeline -p spring-framework-6.0.x -c ci/pipeline.yml -l ci/parameters.yml
----
-
-NOTE: This assumes that you have credhub integration configured with the appropriate secrets.

-== Spring Properties
-
-{api-spring-framework}/core/SpringProperties.html[`SpringProperties`] is a static holder
-for properties that control certain low-level aspects of the Spring Framework. Users can
-configure these properties via JVM system properties or programmatically via the
-`SpringProperties.setProperty(String key, String value)` method. The latter may be
-necessary if the deployment environment disallows custom JVM system properties. As an
-alternative, these properties may be configured in a `spring.properties` file in the root
-of the classpath -- for example, deployed within the application's JAR file.
-
-The following table lists all currently supported Spring properties.
-

-See the note in <<data-access.adoc#jdbc-batch-list, Batch Operations with a List of Objects>>.
-
-| `spring.jndi.ignore`
-| Instructs Spring to ignore a default JNDI environment, as an optimization for scenarios
-where nothing is ever to be found for such JNDI fallback searches to begin with, avoiding
-the repeated JNDI lookup overhead. See
-{api-spring-framework}++/jndi/JndiLocatorDelegate.html#IGNORE_JNDI_PROPERTY_NAME++[`JndiLocatorDelegate`]
-for details.
-
-| `spring.objenesis.ignore`
-| Instructs Spring to ignore Objenesis, not even attempting to use it. See

-= Ahead of Time Optimizations
-
-This chapter covers Spring's Ahead of Time (AOT) optimizations.
-
-For AOT support specific to integration tests, see <<testing.adoc#testcontext-aot, Ahead of Time Support for Tests>>.
-
-[[core.aot.introduction]]
-== Introduction to Ahead of Time Optimizations
-
-Spring's support for AOT optimizations is meant to inspect an `ApplicationContext` at build time and apply decisions and discovery logic that usually happens at runtime.
-Doing so allows building an application startup arrangement that is more straightforward and focused on a fixed set of features based mainly on the classpath and the `Environment`.
-
-Applying such optimizations early implies the following restrictions:
-
-* The classpath is fixed and fully defined at build time.
-* The beans defined in your application cannot change at runtime, meaning:
-** `@Profile`, in particular profile-specific configuration needs to be chosen at build time.
-** Environment properties that impact the presence of a bean (`@Conditional`) are only considered at build time.
-
-When these restrictions are in place, it becomes possible to perform ahead-of-time processing at build time and generate additional assets.
-A Spring AOT processed application typically generates:
-
-* Java source code
-* Bytecode (usually for dynamic proxies)
-* {api-spring-framework}/aot/hint/RuntimeHints.html[`RuntimeHints`] for the use of reflection, resource loading, serialization, and JDK proxies.
-
-NOTE: At the moment, AOT is focused on allowing Spring applications to be deployed as native images using GraalVM.
-We intend to support more JVM-based use cases in future generations.
-
-[[core.aot.basics]]
-== AOT engine overview
-
-The entry point of the AOT engine for processing an `ApplicationContext` arrangement is `ApplicationContextAotGenerator`. It takes care of the following steps, based on a `GenericApplicationContext` that represents the application to optimize and a {api-spring-framework}/aot/generate/GenerationContext.html[`GenerationContext`]:
-
-* Refresh an `ApplicationContext` for AOT processing. Contrary to a traditional refresh, this version only creates bean definitions, not bean instances.
-* Invoke the available `BeanFactoryInitializationAotProcessor` implementations and apply their contributions against the `GenerationContext`.
-For instance, a core implementation iterates over all candidate bean definitions and generates the necessary code to restore the state of the `BeanFactory`.
-
-Once this process completes, the `GenerationContext` will have been updated with the generated code, resources, and classes that are necessary for the application to run.
-The `RuntimeHints` instance can also be used to generate the relevant GraalVM native image configuration files.
-
-`ApplicationContextAotGenerator#processAheadOfTime` returns the class name of the `ApplicationContextInitializer` entry point that allows the context to be started with AOT optimizations.
-
-Those steps are covered in greater detail in the sections below.
-
-[[core.aot.refresh]]
-== Refresh for AOT Processing
-
-Refresh for AOT processing is supported on all `GenericApplicationContext` implementations.
-An application context is created with any number of entry points, usually in the form of `@Configuration`-annotated classes.
-
-Let's look at a basic example:
-
-include::code:AotProcessingSample[tag=myapplication]
-
-Starting this application with the regular runtime involves a number of steps including classpath scanning, configuration class parsing, bean instantiation, and lifecycle callback handling.
-Refresh for AOT processing only applies a subset of what happens with a <<beans-introduction,regular `refresh`>>.
-AOT processing can be triggered as follows:
-
-include::code:AotProcessingSample[tag=aotcontext]
-
-In this mode, <<beans-factory-extension-factory-postprocessors,`BeanFactoryPostProcessor` implementations>> are invoked as usual.
-This includes configuration class parsing, import selectors, classpath scanning, etc.
-Such steps make sure that the `BeanRegistry` contains the relevant bean definitions for the application.
-If bean definitions are guarded by conditions (such as `@Profile`), these are discarded at this stage.
-
-Because this mode does not actually create bean instances, `BeanPostProcessor` implementations are not invoked, except for specific variants that are relevant for AOT processing.
-These are:
-
-* `MergedBeanDefinitionPostProcessor` implementations post-process bean definitions to extract additional settings, such as `init` and `destroy` methods.
-* `SmartInstantiationAwareBeanPostProcessor` implementations determine a more precise bean type if necessary.
-This makes sure to create any proxy that will be required at runtime.
-
-One this part completes, the `BeanFactory` contains the bean definitions that are necessary for the application to run. It does not trigger bean instantiation but allows the AOT engine to inspect the beans that will be created at runtime.
-
-[[core.aot.bean-factory-initialization-contributions]]
-== Bean Factory Initialization AOT Contributions
-
-Components that want to participate in this step can implement the {api-spring-framework}/beans/factory/aot/BeanFactoryInitializationAotProcessor.html[`BeanFactoryInitializationAotProcessor`] interface.
-Each implementation can return an AOT contribution, based on the state of the bean factory.
-
-An AOT contribution is a component that contributes generated code that reproduces a particular behavior.
-It can also contribute `RuntimeHints` to indicate the need for reflection, resource loading, serialization, or JDK proxies.
-
-A `BeanFactoryInitializationAotProcessor` implementation can be registered in `META-INF/spring/aot.factories` with a key equal to the fully qualified name of the interface.
-
-A `BeanFactoryInitializationAotProcessor` can also be implemented directly by a bean.
-In this mode, the bean provides an AOT contribution equivalent to the feature it provides with a regular runtime.
-Consequently, such a bean is automatically excluded from the AOT-optimized context.
-
-[NOTE]
-====
-If a bean implements the `BeanFactoryInitializationAotProcessor` interface, the bean and **all** of its dependencies will be initialized during AOT processing.
-We generally recommend that this interface is only implemented by infrastructure beans such as `BeanFactoryPostProcessor` which have limited dependencies and are already initialized early in the bean factory lifecycle.
-If such a bean is registered using an `@Bean` factory method, ensure the method is `static` so that its enclosing `@Configuration` class does not have to be initialized.
-====
-
-
-[[core.aot.bean-registration-contributions]]
-=== Bean Registration AOT Contributions
-
-A core `BeanFactoryInitializationAotProcessor` implementation is responsible for collecting the necessary contributions for each candidate `BeanDefinition`.
-It does so using a dedicated `BeanRegistrationAotProcessor`.
-
-This interface is used as follows:
-
-* Implemented by a `BeanPostProcessor` bean, to replace its runtime behavior.
-For instance <<beans-factory-extension-bpp-examples-aabpp,`AutowiredAnnotationBeanPostProcessor`>> implements this interface to generate code that injects members annotated with `@Autowired`.
-* Implemented by a type registered in `META-INF/spring/aot.factories` with a key equal to the fully qualified name of the interface.
-Typically used when the bean definition needs to be tuned for specific features of the core framework.
-
-[NOTE]
-====
-If a bean implements the `BeanRegistrationAotProcessor` interface, the bean and **all** of its dependencies will be initialized during AOT processing.
-We generally recommend that this interface is only implemented by infrastructure beans such as `BeanFactoryPostProcessor` which have limited dependencies and are already initialized early in the bean factory lifecycle.
-If such a bean is registered using an `@Bean` factory method, ensure the method is `static` so that its enclosing `@Configuration` class does not have to be initialized.
-====
-
-If no `BeanRegistrationAotProcessor` handles a particular registered bean, a default implementation processes it.
-This is the default behavior, since tuning the generated code for a bean definition should be restricted to corner cases.
-
-Taking our previous example, let's assume that `DataSourceConfiguration` is as follows:
-
-[source,java,indent=0,subs="verbatim,quotes",role="primary"]
-.Java
----
-	@Configuration(proxyBeanMethods = false)
-	public class DataSourceConfiguration {
-
-		@Bean
-		public SimpleDataSource dataSource() {
-			return new SimpleDataSource();
-		}
-
-	}
----
-
-Since there isn't any particular condition on this class, `dataSourceConfiguration` and `dataSource` are identified as candidates.
-The AOT engine will convert the configuration class above to code similar to the following:
-
-[source,java,indent=0,role="primary"]
-.Java
----
-	/**
-	 * Bean definitions for {@link DataSourceConfiguration}
-	 */
-	public class DataSourceConfiguration__BeanDefinitions {
-		/**
-		 * Get the bean definition for 'dataSourceConfiguration'
-		 */
-		public static BeanDefinition getDataSourceConfigurationBeanDefinition() {
-			Class<?> beanType = DataSourceConfiguration.class;
-			RootBeanDefinition beanDefinition = new RootBeanDefinition(beanType);
-			beanDefinition.setInstanceSupplier(DataSourceConfiguration::new);
-			return beanDefinition;
-		}
-
-		/**
-		 * Get the bean instance supplier for 'dataSource'.
-		 */
-		private static BeanInstanceSupplier<SimpleDataSource> getDataSourceInstanceSupplier() {
-			return BeanInstanceSupplier.<SimpleDataSource>forFactoryMethod(DataSourceConfiguration.class, "dataSource")
-					.withGenerator((registeredBean) -> registeredBean.getBeanFactory().getBean(DataSourceConfiguration.class).dataSource());
-		}
-
-		/**
-		 * Get the bean definition for 'dataSource'
-		 */
-		public static BeanDefinition getDataSourceBeanDefinition() {
-			Class<?> beanType = SimpleDataSource.class;
-			RootBeanDefinition beanDefinition = new RootBeanDefinition(beanType);
-			beanDefinition.setInstanceSupplier(getDataSourceInstanceSupplier());
-			return beanDefinition;
-		}
-	}
----
-
-NOTE: The exact code generated may differ depending on the exact nature of your bean definitions.
-
-The generated code above creates bean definitions equivalent to the `@Configuration` class, but in a direct way and without the use of reflection if at all possible.
-There is a bean definition for `dataSourceConfiguration` and one for `dataSourceBean`.
-When a `datasource` instance is required, a `BeanInstanceSupplier` is called.
-This supplier invokes the `dataSource()` method on the `dataSourceConfiguration` bean.
-
-
-[[core.aot.hints]]
-== Runtime Hints
-
-Running an application as a native image requires additional information compared to a regular JVM runtime.
-For instance, GraalVM needs to know ahead of time if a component uses reflection.
-Similarly, classpath resources are not shipped in a native image unless specified explicitly.
-Consequently, if the application needs to load a resource, it must be referenced from the corresponding GraalVM native image configuration file.
-
-The {api-spring-framework}/aot/hint/RuntimeHints.html[`RuntimeHints`] API collects the need for reflection, resource loading, serialization, and JDK proxies at runtime.
-The following example makes sure that `config/app.properties` can be loaded from the classpath at runtime within a native image:
-
-[source,java,indent=0,subs="verbatim,quotes",role="primary"]
-.Java
----
-	runtimeHints.resources().registerPattern("config/app.properties");
----
-
-A number of contracts are handled automatically during AOT processing.
-For instance, the return type of a `@Controller` method is inspected, and relevant reflection hints are added if Spring detects that the type should be serialized (typically to JSON).
-
-For cases that the core container cannot infer, you can register such hints programmatically.
-A number of convenient annotations are also provided for common use cases.
-
-
-[[core.aot.hints.import-runtime-hints]]
-=== `@ImportRuntimeHints`
-
-`RuntimeHintsRegistrar` implementations allow you to get a callback to the `RuntimeHints` instance managed by the AOT engine.
-Implementations of this interface can be registered using `@ImportRuntimeHints` on any Spring bean or `@Bean` factory method.
-`RuntimeHintsRegistrar` implementations are detected and invoked at build time.
-
-include::code:SpellCheckService[]
-
-If at all possible, `@ImportRuntimeHints` should be used as close as possible to the component that requires the hints.
-This way, if the component is not contributed to the `BeanFactory`, the hints won't be contributed either.
-
-It is also possible to register an implementation statically by adding an entry in `META-INF/spring/aot.factories` with a key equal to the fully qualified name of the `RuntimeHintsRegistrar` interface.
-
-
-[[core.aot.hints.reflective]]
-=== `@Reflective`
-
-{api-spring-framework}/aot/hint/annotation/Reflective.html[`@Reflective`] provides an idiomatic way to flag the need for reflection on an annotated element.
-For instance, `@EventListener` is meta-annotated with `@Reflective` since the underlying implementation invokes the annotated method using reflection.
-
-By default, only Spring beans are considered and an invocation hint is registered for the annotated element.
-This can be tuned by specifying a custom `ReflectiveProcessor` implementation via the
-`@Reflective` annotation.
-
-Library authors can reuse this annotation for their own purposes.
-If components other than Spring beans need to be processed, a `BeanFactoryInitializationAotProcessor` can detect the relevant types and use `ReflectiveRuntimeHintsRegistrar` to process them.
-
-
-[[core.aot.hints.register-reflection-for-binding]]
-=== `@RegisterReflectionForBinding`
-
-{api-spring-framework}/aot/hint/annotation/RegisterReflectionForBinding.html[`@RegisterReflectionForBinding`] is a specialization of `@Reflective` that registers the need for serializing arbitrary types.
-A typical use case is the use of DTOs that the container cannot infer, such as using a web client within a method body.
-
-`@RegisterReflectionForBinding` can be applied to any Spring bean at the class level, but it can also be applied directly to a method, field, or constructor to better indicate where the hints are actually required.
-The following example registers `Account` for serialization.
-
-[source,java,indent=0,subs="verbatim,quotes",role="primary"]

----
-	@Component
-	public class OrderService {
-
-		@RegisterReflectionForBinding(Account.class)
-		public void process(Order order) {
-			// ...
-		}

-	}

-[[core.aot.hints.testing]]
-=== Testing Runtime Hints
-
-Spring Core also ships `RuntimeHintsPredicates`, a utility for checking that existing hints match a particular use case.
-This can be used in your own tests to validate that a `RuntimeHintsRegistrar` contains the expected results.
-We can write a test for our `SpellCheckService` and ensure that we will be able to load a dictionary at runtime:
-
-include::code:SpellCheckServiceTests[tag=hintspredicates]
-
-With `RuntimeHintsPredicates`, we can check for reflection, resource, serialization, or proxy generation hints.
-This approach works well for unit tests but implies that the runtime behavior of a component is well known.
-
-You can learn more about the global runtime behavior of an application by running its test suite (or the app itself) with the {docs-graalvm}/native-image/metadata/AutomaticMetadataCollection/[GraalVM tracing agent].
-This agent will record all relevant calls requiring GraalVM hints at runtime and write them out as JSON configuration files.
-
-For more targeted discovery and testing, Spring Framework ships a dedicated module with core AOT testing utilities, `"org.springframework:spring-core-test"`.
-This module contains the RuntimeHints Agent, a Java agent that records all method invocations that are related to runtime hints and helps you to assert that a given `RuntimeHints` instance covers all recorded invocations.
-Let's consider a piece of infrastructure for which we'd like to test the hints we're contributing during the AOT processing phase.
-
-include::code:SampleReflection[]
-
-We can then write a unit test (no native compilation required) that checks our contributed hints:
-
-include::code:SampleReflectionRuntimeHintsTests[]
-
-If you forgot to contribute a hint, the test will fail and provide some details about the invocation:
-
-[source,txt,indent=0,subs="verbatim,quotes"]

-[[databuffers]]
-= Data Buffers and Codecs
-
-Java NIO provides `ByteBuffer` but many libraries build their own byte buffer API on top,
-especially for network operations where reusing buffers and/or using direct buffers is
-beneficial for performance. For example Netty has the `ByteBuf` hierarchy, Undertow uses
-XNIO, Jetty uses pooled byte buffers with a callback to be released, and so on.
-The `spring-core` module provides a set of abstractions to work with various byte buffer
-APIs as follows:
-
-* <<databuffers-factory>> abstracts the creation of a data buffer.
-* <<databuffers-buffer>> represents a byte buffer, which may be
-<<databuffers-buffer-pooled, pooled>>.
-* <<databuffers-utils>> offers utility methods for data buffers.
-* <<Codecs>> decode or encode data buffer streams into higher level objects.
-
-
-
-
-[[databuffers-factory]]
-== `DataBufferFactory`
-
-`DataBufferFactory` is used to create data buffers in one of two ways:
-
-. Allocate a new data buffer, optionally specifying capacity upfront, if known, which is
-more efficient even though implementations of `DataBuffer` can grow and shrink on demand.
-. Wrap an existing `byte[]` or `java.nio.ByteBuffer`, which decorates the given data with
-a `DataBuffer` implementation and that does not involve allocation.
-
-Note that WebFlux applications do not create a `DataBufferFactory` directly but instead
-access it through the `ServerHttpResponse` or the `ClientHttpRequest` on the client side.
-The type of factory depends on the underlying client or server, e.g.
-`NettyDataBufferFactory` for Reactor Netty, `DefaultDataBufferFactory` for others.
-
-
-
-
-[[databuffers-buffer]]
-== `DataBuffer`
-
-The `DataBuffer` interface offers similar operations as `java.nio.ByteBuffer` but also
-brings a few additional benefits some of which are inspired by the Netty `ByteBuf`.
-Below is a partial list of benefits:
-
-* Read and write with independent positions, i.e. not requiring a call to `flip()` to
-alternate between read and write.
-* Capacity expanded on demand as with `java.lang.StringBuilder`.
-* Pooled buffers and reference counting via <<databuffers-buffer-pooled>>.
-* View a buffer as `java.nio.ByteBuffer`, `InputStream`, or `OutputStream`.
-* Determine the index, or the last index, for a given byte.
-
-
-
-
-[[databuffers-buffer-pooled]]
-== `PooledDataBuffer`
-
-As explained in the Javadoc for
-https://docs.oracle.com/javase/8/docs/api/java/nio/ByteBuffer.html[ByteBuffer],
-byte buffers can be direct or non-direct. Direct buffers may reside outside the Java heap
-which eliminates the need for copying for native I/O operations. That makes direct buffers
-particularly useful for receiving and sending data over a socket, but they're also more
-expensive to create and release, which leads to the idea of pooling buffers.
-
-`PooledDataBuffer` is an extension of `DataBuffer` that helps with reference counting which
-is essential for byte buffer pooling. How does it work? When a `PooledDataBuffer` is
-allocated the reference count is at 1. Calls to `retain()` increment the count, while
-calls to `release()` decrement it. As long as the count is above 0, the buffer is
-guaranteed not to be released. When the count is decreased to 0, the pooled buffer can be
-released, which in practice could mean the reserved memory for the buffer is returned to
-the memory pool.
-
-Note that instead of operating on `PooledDataBuffer` directly, in most cases it's better
-to use the convenience methods in `DataBufferUtils` that apply release or retain to a
-`DataBuffer` only if it is an instance of `PooledDataBuffer`.
-
-
-
-
-[[databuffers-utils]]
-== `DataBufferUtils`
-
-`DataBufferUtils` offers a number of utility methods to operate on data buffers:
-
-* Join a stream of data buffers into a single buffer possibly with zero copy, e.g. via
-composite buffers, if that's supported by the underlying byte buffer API.
-* Turn `InputStream` or NIO `Channel` into `Flux<DataBuffer>`, and vice versa a
-`Publisher<DataBuffer>` into `OutputStream` or NIO `Channel`.
-* Methods to release or retain a `DataBuffer` if the buffer is an instance of
-`PooledDataBuffer`.
-* Skip or take from a stream of bytes until a specific byte count.
-
-
-
-
-[[codecs]]
-== Codecs
-
-The `org.springframework.core.codec` package provides the following strategy interfaces:
-
-* `Encoder` to encode `Publisher<T>` into a stream of data buffers.
-* `Decoder` to decode `Publisher<DataBuffer>` into a stream of higher level objects.
-
-The `spring-core` module provides `byte[]`, `ByteBuffer`, `DataBuffer`, `Resource`, and
-`String` encoder and decoder implementations. The `spring-web` module adds Jackson JSON,
-Jackson Smile, JAXB2, Protocol Buffers and other encoders and decoders. See
-<<web-reactive.adoc#webflux-codecs, Codecs>> in the WebFlux section.
-
-
-
-
-[[databuffers-using]]
-== Using `DataBuffer`
-
-When working with data buffers, special care must be taken to ensure buffers are released
-since they may be <<databuffers-buffer-pooled, pooled>>. We'll use codecs to illustrate
-how that works but the concepts apply more generally. Let's see what codecs must do
-internally to manage data buffers.
-
-A `Decoder` is the last to read input data buffers, before creating higher level
-objects, and therefore it must release them as follows:
-
-. If a `Decoder` simply reads each input buffer and is ready to
-release it immediately, it can do so via `DataBufferUtils.release(dataBuffer)`.
-. If a `Decoder` is using `Flux` or `Mono` operators such as `flatMap`, `reduce`, and
-others that prefetch and cache data items internally, or is using operators such as
-`filter`, `skip`, and others that leave out items, then
-`doOnDiscard(DataBuffer.class, DataBufferUtils::release)` must be added to the
-composition chain to ensure such buffers are released prior to being discarded, possibly
-also as a result of an error or cancellation signal.
-. If a `Decoder` holds on to one or more data buffers in any other way, it must
-ensure they are released when fully read, or in case of an error or cancellation signals that
-take place before the cached data buffers have been read and released.
-
-Note that `DataBufferUtils#join` offers a safe and efficient way to aggregate a data
-buffer stream into a single data buffer. Likewise `skipUntilByteCount` and
-`takeUntilByteCount` are additional safe methods for decoders to use.
-
-An `Encoder` allocates data buffers that others must read (and release). So an `Encoder`
-doesn't have much to do. However an `Encoder` must take care to release a data buffer if
-a serialization error occurs while populating the buffer with data. For example:
-
-[source,java,indent=0,subs="verbatim,quotes",role="primary"]
-.Java
----
-	DataBuffer buffer = factory.allocateBuffer();
-	boolean release = true;
-	try {
-		// serialize and populate buffer..
-		release = false;
-	}
-	finally {
-		if (release) {
-			DataBufferUtils.release(buffer);
-		}
-	}
-	return buffer;
----
-[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
-.Kotlin
----
-	val buffer = factory.allocateBuffer()
-	var release = true
-	try {
-		// serialize and populate buffer..
-		release = false
-	} finally {
-		if (release) {
-			DataBufferUtils.release(buffer)
-		}
-	}
-	return buffer
----
-
-The consumer of an `Encoder` is responsible for releasing the data buffers it receives.
-In a WebFlux application, the output of the `Encoder` is used to write to the HTTP server
-response, or to the client HTTP request, in which case releasing the data buffers is the
-responsibility of the code writing to the server response, or to the client request.

-[[null-safety]]
-= Null-safety
-
-Although Java does not let you express null-safety with its type system, the Spring Framework
-now provides the following annotations in the `org.springframework.lang` package to let you
-declare nullability of APIs and fields:
-
-* {api-spring-framework}/lang/Nullable.html[`@Nullable`]: Annotation to indicate that a
-specific parameter, return value, or field can be `null`.
-* {api-spring-framework}/lang/NonNull.html[`@NonNull`]: Annotation to indicate that a specific
-parameter, return value, or field cannot be `null` (not needed on parameters / return values
-and fields where `@NonNullApi` and `@NonNullFields` apply, respectively).
-* {api-spring-framework}/lang/NonNullApi.html[`@NonNullApi`]: Annotation at the package level
-that declares non-null as the default semantics for parameters and return values.
-* {api-spring-framework}/lang/NonNullFields.html[`@NonNullFields`]: Annotation at the package
-level that declares non-null as the default semantics for fields.
-
-The Spring Framework itself leverages these annotations, but they can also be used in any
-Spring-based Java project to declare null-safe APIs and optionally null-safe fields.
-Generic type arguments, varargs and array elements nullability are not supported yet but
-should be in an upcoming release, see https://jira.spring.io/browse/SPR-15942[SPR-15942]
-for up-to-date information. Nullability declarations are expected to be fine-tuned between
-Spring Framework releases, including minor ones. Nullability of types used inside method
-bodies is outside of the scope of this feature.
-
-NOTE: Other common libraries such as Reactor and Spring Data provide null-safe APIs that
-use a similar nullability arrangement, delivering a consistent overall experience for
-Spring application developers.
-
-
-
-
-== Use cases
-
-In addition to providing an explicit declaration for Spring Framework API nullability,
-these annotations can be used by an IDE (such as IDEA or Eclipse) to provide useful
-warnings related to null-safety in order to avoid `NullPointerException` at runtime.
-
-They are also used to make Spring API null-safe in Kotlin projects, since Kotlin natively
-supports https://kotlinlang.org/docs/reference/null-safety.html[null-safety]. More details
-are available in the <<languages#kotlin-null-safety, Kotlin support documentation>>.

-Spring annotations are meta-annotated with https://jcp.org/en/jsr/detail?id=305[JSR 305]

-like IDEA or Kotlin provide null-safety support in a generic way, without having to
-hard-code support for Spring annotations.
-
-It is not necessary nor recommended to add a JSR-305 dependency to the project classpath to
-take advantage of Spring null-safe API. Only projects such as Spring-based libraries that use
-null-safety annotations in their codebase should add `com.google.code.findbugs:jsr305:3.0.2`

-[[resources-introduction]]
-== Introduction
-
-Java's standard `java.net.URL` class and standard handlers for various URL prefixes,
-unfortunately, are not quite adequate enough for all access to low-level resources. For
-example, there is no standardized `URL` implementation that may be used to access a
-resource that needs to be obtained from the classpath or relative to a
-`ServletContext`. While it is possible to register new handlers for specialized `URL`
-prefixes (similar to existing handlers for prefixes such as `http:`), this is generally
-quite complicated, and the `URL` interface still lacks some desirable functionality,
-such as a method to check for the existence of the resource being pointed to.
-
-
-
-
-[[resources-resource]]
-== The `Resource` Interface
-
-Spring's `Resource` interface located in the `org.springframework.core.io.` package is
-meant to be a more capable interface for abstracting access to low-level resources. The
-following listing provides an overview of the `Resource` interface. See the
-{api-spring-framework}/core/io/Resource.html[`Resource`] javadoc for further details.
-
-
-[source,java,indent=0,subs="verbatim,quotes"]
----
-	public interface Resource extends InputStreamSource {
-
-		boolean exists();
-
-		boolean isReadable();
-
-		boolean isOpen();
-
-		boolean isFile();
-
-		URL getURL() throws IOException;
-
-		URI getURI() throws IOException;
-
-		File getFile() throws IOException;
-
-		ReadableByteChannel readableChannel() throws IOException;
-
-		long contentLength() throws IOException;
-
-		long lastModified() throws IOException;
-
-		Resource createRelative(String relativePath) throws IOException;
-
-		String getFilename();
-
-		String getDescription();
-	}
----
-
-As the definition of the `Resource` interface shows, it extends the `InputStreamSource`
-interface. The following listing shows the definition of the `InputStreamSource`
-interface:
-
-[source,java,indent=0,subs="verbatim,quotes"]
----
-	public interface InputStreamSource {
-
-		InputStream getInputStream() throws IOException;
-	}
----
-
-Some of the most important methods from the `Resource` interface are:
-
-* `getInputStream()`: Locates and opens the resource, returning an `InputStream` for
-  reading from the resource. It is expected that each invocation returns a fresh
-  `InputStream`. It is the responsibility of the caller to close the stream.
-* `exists()`: Returns a `boolean` indicating whether this resource actually exists in
-  physical form.
-* `isOpen()`: Returns a `boolean` indicating whether this resource represents a handle
-  with an open stream. If `true`, the `InputStream` cannot be read multiple times and
-  must be read once only and then closed to avoid resource leaks. Returns `false` for
-  all usual resource implementations, with the exception of `InputStreamResource`.
-* `getDescription()`: Returns a description for this resource, to be used for error
-  output when working with the resource. This is often the fully qualified file name or
-  the actual URL of the resource.
-
-Other methods let you obtain an actual `URL` or `File` object representing the
-resource (if the underlying implementation is compatible and supports that
-functionality).
-
-Some implementations of the `Resource` interface also implement the extended
-{api-spring-framework}/core/io/WritableResource.html[`WritableResource`] interface
-for a resource that supports writing to it.
-
-Spring itself uses the `Resource` abstraction extensively, as an argument type in
-many method signatures when a resource is needed. Other methods in some Spring APIs
-(such as the constructors to various `ApplicationContext` implementations) take a
-`String` which in unadorned or simple form is used to create a `Resource` appropriate to
-that context implementation or, via special prefixes on the `String` path, let the
-caller specify that a specific `Resource` implementation must be created and used.
-
-While the `Resource` interface is used a lot with Spring and by Spring, it is actually
-very convenient to use as a general utility class by itself in your own code, for access
-to resources, even when your code does not know or care about any other parts of Spring.
-While this couples your code to Spring, it really only couples it to this small set of
-utility classes, which serves as a more capable replacement for `URL` and can be
-considered equivalent to any other library you would use for this purpose.
-
-NOTE: The `Resource` abstraction does not replace functionality. It wraps it where
-possible. For example, a `UrlResource` wraps a URL and uses the wrapped `URL` to do its
-work.
-
-
-
-
-[[resources-implementations]]
-== Built-in `Resource` Implementations
-
-Spring includes several built-in `Resource` implementations:
-
-* <<resources-implementations-urlresource>>
-* <<resources-implementations-classpathresource>>
-* <<resources-implementations-filesystemresource>>
-* <<resources-implementations-pathresource>>
-* <<resources-implementations-servletcontextresource>>
-* <<resources-implementations-inputstreamresource>>

-"All Known Implementing Classes" section of the
-{api-spring-framework}/core/io/Resource.html[`Resource`] javadoc.
-
-
-
-[[resources-implementations-urlresource]]
-=== `UrlResource`
-
-`UrlResource` wraps a `java.net.URL` and can be used to access any object that is
-normally accessible with a URL, such as files, an HTTPS target, an FTP target, and
-others. All URLs have a standardized `String` representation, such that appropriate
-standardized prefixes are used to indicate one URL type from another. This includes
-`file:` for accessing filesystem paths, `https:` for accessing resources through the
-HTTPS protocol, `ftp:` for accessing resources through FTP, and others.
-
-A `UrlResource` is created by Java code by explicitly using the `UrlResource` constructor
-but is often created implicitly when you call an API method that takes a `String`
-argument meant to represent a path. For the latter case, a JavaBeans `PropertyEditor`
-ultimately decides which type of `Resource` to create. If the path string contains a
-well-known (to property editor, that is) prefix (such as `classpath:`), it creates an
-appropriate specialized `Resource` for that prefix. However, if it does not recognize the
-prefix, it assumes the string is a standard URL string and creates a `UrlResource`.
-
-
-
-[[resources-implementations-classpathresource]]
-=== `ClassPathResource`
-
-This class represents a resource that should be obtained from the classpath. It uses
-either the thread context class loader, a given class loader, or a given class for
-loading resources.
-
-This `Resource` implementation supports resolution as a `java.io.File` if the class path
-resource resides in the file system but not for classpath resources that reside in a
-jar and have not been expanded (by the servlet engine or whatever the environment is)
-to the filesystem. To address this, the various `Resource` implementations always support
-resolution as a `java.net.URL`.
-
-A `ClassPathResource` is created by Java code by explicitly using the `ClassPathResource`
-constructor but is often created implicitly when you call an API method that takes a
-`String` argument meant to represent a path. For the latter case, a JavaBeans
-`PropertyEditor` recognizes the special prefix, `classpath:`, on the string path and
-creates a `ClassPathResource` in that case.
-
-
-
-[[resources-implementations-filesystemresource]]
-=== `FileSystemResource`
-
-This is a `Resource` implementation for `java.io.File` handles. It also supports
-`java.nio.file.Path` handles, applying Spring's standard String-based path
-transformations but performing all operations via the `java.nio.file.Files` API. For pure
-`java.nio.path.Path` based support use a `PathResource` instead. `FileSystemResource`
-supports resolution as a `File` and as a `URL`.
-
-
-
-[[resources-implementations-pathresource]]
-=== `PathResource`
-
-This is a `Resource` implementation for `java.nio.file.Path` handles, performing all
-operations and transformations via the `Path` API. It supports resolution as a `File` and
-as a `URL` and also implements the extended `WritableResource` interface. `PathResource`
-is effectively a pure `java.nio.path.Path` based alternative to `FileSystemResource` with
-different `createRelative` behavior.
-
-
-
-[[resources-implementations-servletcontextresource]]
-=== `ServletContextResource`
-
-This is a `Resource` implementation for `ServletContext` resources that interprets
-relative paths within the relevant web application's root directory.
-
-It always supports stream access and URL access but allows `java.io.File` access only
-when the web application archive is expanded and the resource is physically on the
-filesystem. Whether or not it is expanded and on the filesystem or accessed
-directly from the JAR or somewhere else like a database (which is conceivable) is actually
-dependent on the Servlet container.
-
-
-
-[[resources-implementations-inputstreamresource]]
-=== `InputStreamResource`
-
-An `InputStreamResource` is a `Resource` implementation for a given `InputStream`. It
-should be used only if no specific `Resource` implementation is applicable. In
-particular, prefer `ByteArrayResource` or any of the file-based `Resource`
-implementations where possible.
-
-In contrast to other `Resource` implementations, this is a descriptor for an
-already-opened resource. Therefore, it returns `true` from `isOpen()`. Do not use it if
-you need to keep the resource descriptor somewhere or if you need to read a stream
-multiple times.
-
-
-
-[[resources-implementations-bytearrayresource]]
-=== `ByteArrayResource`
-
-This is a `Resource` implementation for a given byte array. It creates a
-`ByteArrayInputStream` for the given byte array.
-
-It is useful for loading content from any given byte array without having to resort to a
-single-use `InputStreamResource`.
-
-
-
-
-[[resources-resourceloader]]
-== The `ResourceLoader` Interface
-
-The `ResourceLoader` interface is meant to be implemented by objects that can return
-(that is, load) `Resource` instances. The following listing shows the `ResourceLoader`
-interface definition:
-
-[source,java,indent=0,subs="verbatim,quotes"]
----
-	public interface ResourceLoader {
-
-		Resource getResource(String location);
-
-		ClassLoader getClassLoader();
-	}
----
-
-All application contexts implement the `ResourceLoader` interface. Therefore, all
-application contexts may be used to obtain `Resource` instances.
-
-When you call `getResource()` on a specific application context, and the location path
-specified doesn't have a specific prefix, you get back a `Resource` type that is
-appropriate to that particular application context. For example, assume the following
-snippet of code was run against a `ClassPathXmlApplicationContext` instance:
-
-[source,java,indent=0,subs="verbatim,quotes",role="primary"]
-.Java
----
-	Resource template = ctx.getResource("some/resource/path/myTemplate.txt");
----
-[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
-.Kotlin
----
-	val template = ctx.getResource("some/resource/path/myTemplate.txt")
----
-
-Against a `ClassPathXmlApplicationContext`, that code returns a `ClassPathResource`. If
-the same method were run against a `FileSystemXmlApplicationContext` instance, it would
-return a `FileSystemResource`. For a `WebApplicationContext`, it would return a
-`ServletContextResource`. It would similarly return appropriate objects for each context.
-
-As a result, you can load resources in a fashion appropriate to the particular application
-context.
-
-On the other hand, you may also force `ClassPathResource` to be used, regardless of the
-application context type, by specifying the special `classpath:` prefix, as the following
-example shows:
-
-[source,java,indent=0,subs="verbatim,quotes",role="primary"]
-.Java
----
-	Resource template = ctx.getResource("classpath:some/resource/path/myTemplate.txt");
----
-[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
-.Kotlin
----
-	val template = ctx.getResource("classpath:some/resource/path/myTemplate.txt")
----
-
-Similarly, you can force a `UrlResource` to be used by specifying any of the standard
-`java.net.URL` prefixes. The following examples use the `file` and `https` prefixes:
-
-[source,java,indent=0,subs="verbatim,quotes",role="primary"]
-.Java
----
-	Resource template = ctx.getResource("file:///some/resource/path/myTemplate.txt");
----
-[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]

-== The `ResourcePatternResolver` Interface
-
-The `ResourcePatternResolver` interface is an extension to the `ResourceLoader` interface
-which defines a strategy for resolving a location pattern (for example, an Ant-style path
-pattern) into  `Resource` objects.
-
-[source,java,indent=0,subs="verbatim,quotes"]
----
-	public interface ResourcePatternResolver extends ResourceLoader {
-
-		String CLASSPATH_ALL_URL_PREFIX = "classpath*:";
-
-		Resource[] getResources(String locationPattern) throws IOException;
-	}
----
-
-As can be seen above, this interface also defines a special `classpath*:` resource prefix
-for all matching resources from the class path. Note that the resource location is
-expected to be a path without placeholders in this case -- for example,
-`classpath*:/config/beans.xml`. JAR files or different directories in the class path can
-contain multiple files with the same path and the same name. See
-<<resources-app-ctx-wildcards-in-resource-paths>> and its subsections for further details
-on wildcard support with the `classpath*:` resource prefix.
-
-A passed-in `ResourceLoader` (for example, one supplied via
-<<resources-resourceloaderaware,`ResourceLoaderAware`>> semantics) can be checked whether
-it implements this extended interface too.
-
-`PathMatchingResourcePatternResolver` is a standalone implementation that is usable
-outside an `ApplicationContext` and is also used by `ResourceArrayPropertyEditor` for
-populating `Resource[]` bean properties. `PathMatchingResourcePatternResolver` is able to
-resolve a specified resource location path into one or more matching `Resource` objects.
-The source path may be a simple path which has a one-to-one mapping to a target
-`Resource`, or alternatively may contain the special `classpath*:` prefix and/or internal
-Ant-style regular expressions (matched using Spring's
-`org.springframework.util.AntPathMatcher` utility). Both of the latter are effectively
-wildcards.
-
-[NOTE]
-====
-The default `ResourceLoader` in any standard `ApplicationContext` is in fact an instance
-of `PathMatchingResourcePatternResolver` which implements the `ResourcePatternResolver`
-interface. The same is true for the `ApplicationContext` instance itself which also
-implements the `ResourcePatternResolver` interface and delegates to the default
-`PathMatchingResourcePatternResolver`.
-====
-
-
-
-
-[[resources-resourceloaderaware]]
-== The `ResourceLoaderAware` Interface
-
-The `ResourceLoaderAware` interface is a special callback interface which identifies
-components that expect to be provided a `ResourceLoader` reference. The following listing
-shows the definition of the `ResourceLoaderAware` interface:
-
-[source,java,indent=0,subs="verbatim,quotes"]
----
-	public interface ResourceLoaderAware {
-
-		void setResourceLoader(ResourceLoader resourceLoader);
-	}
----
-
-When a class implements `ResourceLoaderAware` and is deployed into an application context
-(as a Spring-managed bean), it is recognized as `ResourceLoaderAware` by the application
-context. The application context then invokes `setResourceLoader(ResourceLoader)`,
-supplying itself as the argument (remember, all application contexts in Spring implement
-the `ResourceLoader` interface).
-
-Since an `ApplicationContext` is a `ResourceLoader`, the bean could also implement the
-`ApplicationContextAware` interface and use the supplied application context directly to
-load resources. However, in general, it is better to use the specialized `ResourceLoader`
-interface if that is all you need. The code would be coupled only to the resource loading
-interface (which can be considered a utility interface) and not to the whole Spring
-`ApplicationContext` interface.
-
-In application components, you may also rely upon autowiring of the `ResourceLoader` as
-an alternative to implementing the `ResourceLoaderAware` interface. The _traditional_
-`constructor` and `byType` autowiring modes (as described in <<beans-factory-autowire>>)
-are capable of providing a `ResourceLoader` for either a constructor argument or a
-setter method parameter, respectively. For more flexibility (including the ability to
-autowire fields and multiple parameter methods), consider using the annotation-based
-autowiring features. In that case, the `ResourceLoader` is autowired into a field,
-constructor argument, or method parameter that expects the `ResourceLoader` type as long
-as the field, constructor, or method in question carries the `@Autowired` annotation.
-For more information, see <<beans-autowired-annotation>>.
-
-NOTE: To load one or more `Resource` objects for a resource path that contains wildcards
-or makes use of the special `classpath*:` resource prefix, consider having an instance of
-<<resources-resourcepatternresolver,`ResourcePatternResolver`>> autowired into your
-application components instead of `ResourceLoader`.
-
-
-
-
-[[resources-as-dependencies]]
-== Resources as Dependencies
-
-If the bean itself is going to determine and supply the resource path through some sort
-of dynamic process, it probably makes sense for the bean to use the `ResourceLoader` or
-`ResourcePatternResolver` interface to load resources. For example, consider the loading
-of a template of some sort, where the specific resource that is needed depends on the
-role of the user. If the resources are static, it makes sense to eliminate the use of the
-`ResourceLoader` interface (or `ResourcePatternResolver` interface) completely, have the
-bean expose the `Resource` properties it needs, and expect them to be injected into it.
-
-What makes it trivial to then inject these properties is that all application contexts
-register and use a special JavaBeans `PropertyEditor`, which can convert `String` paths
-to `Resource` objects. For example, the following `MyBean` class has a `template`
-property of type `Resource`.
-
-[source,java,indent=0,subs="verbatim,quotes",role="primary"]
-.Java
----
-	package example;
-
-	public class MyBean {
-
-		private Resource template;
-
-		public setTemplate(Resource template) {
-			this.template = template;
-		}
-
-		// ...
-	}
----
-[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
-.Kotlin
----
-	class MyBean(var template: Resource)
----
-
-In an XML configuration file, the `template` property can be configured with a simple
-string for that resource, as the following example shows:
-
-[source,xml,indent=0,subs="verbatim,quotes"]
----
-	<bean id="myBean" class="example.MyBean">
-		<property name="template" value="some/resource/path/myTemplate.txt"/>
-	</bean>
----
-
-Note that the resource path has no prefix. Consequently, because the application context
-itself is going to be used as the `ResourceLoader`, the resource is loaded through a
-`ClassPathResource`, a `FileSystemResource`, or a `ServletContextResource`, depending on
-the exact type of the application context.
-
-If you need to force a specific `Resource` type to be used, you can use a prefix. The
-following two examples show how to force a `ClassPathResource` and a `UrlResource` (the
-latter being used to access a file in the filesystem):
-
-[source,xml,indent=0,subs="verbatim,quotes"]
----
-	<property name="template" value="classpath:some/resource/path/myTemplate.txt">
----
-
-[source,xml,indent=0,subs="verbatim,quotes"]
----
-	<property name="template" value="file:///some/resource/path/myTemplate.txt"/>
----
-
-If the `MyBean` class is refactored for use with annotation-driven configuration, the
-path to `myTemplate.txt` can be stored under a key named `template.path` -- for example,
-in a properties file made available to the Spring `Environment` (see
-<<beans-environment>>). The template path can then be referenced via the `@Value`
-annotation using a property placeholder (see <<beans-value-annotations>>). Spring will
-retrieve the value of the template path as a string, and a special `PropertyEditor` will
-convert the string to a `Resource` object to be injected into the `MyBean` constructor.
-The following example demonstrates how to achieve this.
-
-[source,java,indent=0,subs="verbatim,quotes",role="primary"]
-.Java
----
-	@Component
-	public class MyBean {
-
-		private final Resource template;

-
-If we want to support multiple templates discovered under the same path in multiple
-locations in the classpath -- for example, in multiple jars in the classpath -- we can
-use the special `classpath*:` prefix and wildcarding to define a `templates.path` key as
-`classpath*:/config/templates/*.txt`. If we redefine the `MyBean` class as follows,
-Spring will convert the template path pattern into an array of `Resource` objects that
-can be injected into the `MyBean` constructor.

-[[resources-app-ctx]]
-== Application Contexts and Resource Paths
-
-This section covers how to create application contexts with resources, including shortcuts
-that work with XML, how to use wildcards, and other details.
-
-
-
-[[resources-app-ctx-construction]]
-=== Constructing Application Contexts
-
-An application context constructor (for a specific application context type) generally
-takes a string or array of strings as the location paths of the resources, such as
-XML files that make up the definition of the context.
-
-When such a location path does not have a prefix, the specific `Resource` type built from
-that path and used to load the bean definitions depends on and is appropriate to the
-specific application context. For example, consider the following example, which creates a
-`ClassPathXmlApplicationContext`:
-
-[source,java,indent=0,subs="verbatim,quotes",role="primary"]
-.Java
----
-	ApplicationContext ctx = new ClassPathXmlApplicationContext("conf/appContext.xml");
----
-[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
-.Kotlin
----
-	val ctx = ClassPathXmlApplicationContext("conf/appContext.xml")
----
-
-The bean definitions are loaded from the classpath, because a `ClassPathResource` is
-used. However, consider the following example, which creates a `FileSystemXmlApplicationContext`:
-
-[source,java,indent=0,subs="verbatim,quotes",role="primary"]
-.Java
----
-	ApplicationContext ctx =
-		new FileSystemXmlApplicationContext("conf/appContext.xml");
----
-[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
-.Kotlin
----
-	val ctx = FileSystemXmlApplicationContext("conf/appContext.xml")
----
-
-Now the bean definitions are loaded from a filesystem location (in this case, relative to
-the current working directory).
-
-Note that the use of the special `classpath` prefix or a standard URL prefix on the
-location path overrides the default type of `Resource` created to load the bean
-definitions. Consider the following example:
-
-[source,java,indent=0,subs="verbatim,quotes",role="primary"]
-.Java
----
-	ApplicationContext ctx =
-		new FileSystemXmlApplicationContext("classpath:conf/appContext.xml");
----
-[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
-.Kotlin
----
-	val ctx = FileSystemXmlApplicationContext("classpath:conf/appContext.xml")
----
-
-Using `FileSystemXmlApplicationContext` loads the bean definitions from the classpath.
-However, it is still a `FileSystemXmlApplicationContext`. If it is subsequently used as a
-`ResourceLoader`, any unprefixed paths are still treated as filesystem paths.
-
-
-[[resources-app-ctx-classpathxml]]
-==== Constructing `ClassPathXmlApplicationContext` Instances -- Shortcuts
-
-The `ClassPathXmlApplicationContext` exposes a number of constructors to enable
-convenient instantiation. The basic idea is that you can supply merely a string array
-that contains only the filenames of the XML files themselves (without the leading path
-information) and also supply a `Class`. The `ClassPathXmlApplicationContext` then derives
-the path information from the supplied class.
-
-Consider the following directory layout:
-
-[literal,subs="verbatim,quotes"]
----
-com/
-  example/
-    services.xml
-    repositories.xml
-    MessengerService.class
----
-
-The following example shows how a `ClassPathXmlApplicationContext` instance composed of
-the beans defined in files named `services.xml` and `repositories.xml` (which are on the
-classpath) can be instantiated:
-
-[source,java,indent=0,subs="verbatim,quotes",role="primary"]
-.Java
----
-	ApplicationContext ctx = new ClassPathXmlApplicationContext(
-		new String[] {"services.xml", "repositories.xml"}, MessengerService.class);
----
-[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
-.Kotlin
----
-	val ctx = ClassPathXmlApplicationContext(arrayOf("services.xml", "repositories.xml"), MessengerService::class.java)
----
-
-See the {api-spring-framework}/context/support/ClassPathXmlApplicationContext.html[`ClassPathXmlApplicationContext`]
-javadoc for details on the various constructors.
-
-
-
-[[resources-app-ctx-wildcards-in-resource-paths]]
-=== Wildcards in Application Context Constructor Resource Paths
-
-The resource paths in application context constructor values may be simple paths (as
-shown earlier), each of which has a one-to-one mapping to a target `Resource` or,
-alternately, may contain the special `classpath*:` prefix or internal Ant-style patterns
-(matched by using Spring's `PathMatcher` utility). Both of the latter are effectively
-wildcards.
-
-One use for this mechanism is when you need to do component-style application assembly. All
-components can _publish_ context definition fragments to a well-known location path, and,
-when the final application context is created using the same path prefixed with
-`classpath*:`, all component fragments are automatically picked up.
-
-Note that this wildcarding is specific to the use of resource paths in application context
-constructors (or when you use the `PathMatcher` utility class hierarchy directly) and is
-resolved at construction time. It has nothing to do with the `Resource` type itself.
-You cannot use the `classpath*:` prefix to construct an actual `Resource`, as
-a resource points to just one resource at a time.
-
-
-[[resources-app-ctx-ant-patterns-in-paths]]
-==== Ant-style Patterns
-
-Path locations can contain Ant-style patterns, as the following example shows:
-
-[literal,subs="verbatim,quotes"]
----
-/WEB-INF/\*-context.xml
-com/mycompany/\**/applicationContext.xml
-file:C:/some/path/\*-context.xml
-classpath:com/mycompany/**/applicationContext.xml
----
-
-When the path location contains an Ant-style pattern, the resolver follows a more complex
-procedure to try to resolve the wildcard. It produces a `Resource` for the path up to the
-last non-wildcard segment and obtains a URL from it. If this URL is not a `jar:` URL or
-container-specific variant (such as `zip:` in WebLogic, `wsjar` in WebSphere, and so on),
-a `java.io.File` is obtained from it and used to resolve the wildcard by traversing the
-filesystem. In the case of a jar URL, the resolver either gets a
-`java.net.JarURLConnection` from it or manually parses the jar URL and then traverses the
-contents of the jar file to resolve the wildcards.
-
-[[resources-app-ctx-portability]]
-===== Implications on Portability
-
-If the specified path is already a `file` URL (either implicitly because the base
-`ResourceLoader` is a filesystem one or explicitly), wildcarding is guaranteed to
-work in a completely portable fashion.
-
-If the specified path is a `classpath` location, the resolver must obtain the last
-non-wildcard path segment URL by making a `Classloader.getResource()` call. Since this
-is just a node of the path (not the file at the end), it is actually undefined (in the
-`ClassLoader` javadoc) exactly what sort of a URL is returned in this case. In practice,
-it is always a `java.io.File` representing the directory (where the classpath resource
-resolves to a filesystem location) or a jar URL of some sort (where the classpath resource
-resolves to a jar location). Still, there is a portability concern on this operation.
-
-If a jar URL is obtained for the last non-wildcard segment, the resolver must be able to
-get a `java.net.JarURLConnection` from it or manually parse the jar URL, to be able to
-walk the contents of the jar and resolve the wildcard. This does work in most environments
-but fails in others, and we strongly recommend that the wildcard resolution of resources
-coming from jars be thoroughly tested in your specific environment before you rely on it.
-
-
-[[resources-classpath-wildcards]]
-==== The `classpath*:` Prefix
-
-When constructing an XML-based application context, a location string may use the
-special `classpath*:` prefix, as the following example shows:
-
-[source,java,indent=0,subs="verbatim,quotes",role="primary"]
-.Java
----
-	ApplicationContext ctx =
-		new ClassPathXmlApplicationContext("classpath*:conf/appContext.xml");
----
-[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
-.Kotlin
----
-	val ctx = ClassPathXmlApplicationContext("classpath*:conf/appContext.xml")
----
-
-This special prefix specifies that all classpath resources that match the given name
-must be obtained (internally, this essentially happens through a call to
-`ClassLoader.getResources(...)`) and then merged to form the final application
-context definition.
-
-NOTE: The wildcard classpath relies on the `getResources()` method of the underlying
-`ClassLoader`. As most application servers nowadays supply their own `ClassLoader`
-implementation, the behavior might differ, especially when dealing with jar files. A
-simple test to check if `classpath*` works is to use the `ClassLoader` to load a file from
-within a jar on the classpath:
-`getClass().getClassLoader().getResources("<someFileInsideTheJar>")`. Try this test with
-files that have the same name but reside in two different locations -- for example, files
-with the same name and same path but in different jars on the classpath. In case an
-inappropriate result is returned, check the application server documentation for settings
-that might affect the `ClassLoader` behavior.
-
-You can also combine the `classpath*:` prefix with a `PathMatcher` pattern in the
-rest of the location path (for example, `classpath*:META-INF/*-beans.xml`). In this
-case, the resolution strategy is fairly simple: A `ClassLoader.getResources()` call is
-used on the last non-wildcard path segment to get all the matching resources in the
-class loader hierarchy and then, off each resource, the same `PathMatcher` resolution
-strategy described earlier is used for the wildcard subpath.
-
-
-[[resources-wildcards-in-path-other-stuff]]
-==== Other Notes Relating to Wildcards
-
-Note that `classpath*:`, when combined with Ant-style patterns, only works
-reliably with at least one root directory before the pattern starts, unless the actual
-target files reside in the file system. This means that a pattern such as
-`classpath*:*.xml` might not retrieve files from the root of jar files but rather only
-from the root of expanded directories.
-
-Spring's ability to retrieve classpath entries originates from the JDK's
-`ClassLoader.getResources()` method, which only returns file system locations for an
-empty string (indicating potential roots to search). Spring evaluates
-`URLClassLoader` runtime configuration and the `java.class.path` manifest in jar files
-as well, but this is not guaranteed to lead to portable behavior.
-
-[NOTE]
-====
-The scanning of classpath packages requires the presence of corresponding directory
-entries in the classpath. When you build JARs with Ant, do not activate the `files-only`
-switch of the JAR task. Also, classpath directories may not get exposed based on security
-policies in some environments -- for example, stand-alone applications on JDK 1.7.0_45
-and higher (which requires 'Trusted-Library' to be set up in your manifests. See
-https://stackoverflow.com/questions/19394570/java-jre-7u45-breaks-classloader-getresources).
-
-On JDK 9's module path (Jigsaw), Spring's classpath scanning generally works as expected.
-Putting resources into a dedicated directory is highly recommendable here as well,
-avoiding the aforementioned portability problems with searching the jar file root level.
-====
-
-Ant-style patterns with `classpath:` resources are not guaranteed to find matching
-resources if the root package to search is available in multiple classpath locations.
-Consider the following example of a resource location:
-
-[literal,subs="verbatim,quotes"]
----
-com/mycompany/package1/service-context.xml
----
-
-Now consider an Ant-style path that someone might use to try to find that file:
-
-[literal,subs="verbatim,quotes"]
----
-classpath:com/mycompany/**/service-context.xml
----
-
-Such a resource may exist in only one location in the classpath, but when a path such as
-the preceding example is used to try to resolve it, the resolver works off the (first)
-URL returned by `getResource("com/mycompany");`. If this base package node exists in
-multiple `ClassLoader` locations, the desired resource may not exist in the first
-location found. Therefore, in such cases you should prefer using `classpath*:` with the
-same Ant-style pattern, which searches all classpath locations that contain the
-`com.mycompany` base package: `classpath*:com/mycompany/**/service-context.xml`.
-
-
-
-[[resources-filesystemresource-caveats]]
-=== `FileSystemResource` Caveats
-
-A `FileSystemResource` that is not attached to a `FileSystemApplicationContext` (that
-is, when a `FileSystemApplicationContext` is not the actual `ResourceLoader`) treats
-absolute and relative paths as you would expect. Relative paths are relative to the
-current working directory, while absolute paths are relative to the root of the
-filesystem.
-
-For backwards compatibility (historical) reasons however, this changes when the
-`FileSystemApplicationContext` is the `ResourceLoader`. The
-`FileSystemApplicationContext` forces all attached `FileSystemResource` instances
-to treat all location paths as relative, whether they start with a leading slash or not.
-In practice, this means the following examples are equivalent:
-
-[source,java,indent=0,subs="verbatim,quotes",role="primary"]

-	ApplicationContext ctx =
-		new FileSystemXmlApplicationContext("conf/context.xml");

-case is relative and the other absolute):

-In practice, if you need true absolute filesystem paths, you should avoid using

-force the use of a `UrlResource` by using the `file:` URL prefix. The following examples

-The `tx` tags deal with configuring all of those beans in Spring's comprehensive support
-for transactions. These tags are covered in the chapter entitled
-<<data-access.adoc#transaction, Transaction Management>>.
-
-TIP: We strongly encourage you to look at the `'spring-tx.xsd'` file that ships with the
-Spring distribution. This file contains the XML Schema for Spring's transaction
-configuration and covers all of the various elements in the `tx` namespace, including
-attribute defaults and similar information. This file is documented inline, and, thus,
-the information is not repeated here in the interests of adhering to the DRY (Don't
-Repeat Yourself) principle.
-
-In the interest of completeness, to use the elements in the `tx` schema, you need to have
-the following preamble at the top of your Spring XML configuration file. The text in the
-following snippet references the correct schema so that the tags in the `tx` namespace
-are available to you:
-
-[source,xml,indent=0,subs="verbatim,quotes"]

-<2> Specify the location (with other schema locations).
-
-NOTE: Often, when you use the elements in the `tx` namespace, you are also using the
-elements from the `aop` namespace (since the declarative transaction support in Spring is
-implemented by using AOP). The preceding XML snippet contains the relevant lines needed
-to reference the `aop` schema so that the elements in the `aop` namespace are available
-to you.
-
-
-
-[[xsd-schemas-jdbc]]
-=== The `jdbc` Schema
-
-The `jdbc` elements let you quickly configure an embedded database or initialize an
-existing data source. These elements are documented in
-<<data-access.adoc#jdbc-embedded-database-support, Embedded Database Support>> and
-<<data-access.adoc#jdbc-initializing-datasource, Initializing a DataSource>>, respectively.
-
-To use the elements in the `jdbc` schema, you need to have the following preamble at the
-top of your Spring XML configuration file. The text in the following snippet references
-the correct schema so that the elements in the `jdbc` namespace are available to you:

-[[mail]]
-= Email
-
-This section describes how to send email with the Spring Framework.
-
-.Library dependencies
-****
-The following JAR needs to be on the classpath of your application in order to use
-the Spring Framework's email library:
-
-* The https://eclipse-ee4j.github.io/mail/[JavaMail / Jakarta Mail 1.6] library
-
-This library is freely available on the web -- for example, in Maven Central as
-`com.sun.mail:jakarta.mail`. Please make sure to use the latest 1.6.x version
-rather than Jakarta Mail 2.0 (which comes with a different package namespace).
-****
-
-The Spring Framework provides a helpful utility library for sending email that shields
-you from the specifics of the underlying mailing system and is responsible for
-low-level resource handling on behalf of the client.
-
-The `org.springframework.mail` package is the root level package for the Spring
-Framework's email support. The central interface for sending emails is the `MailSender`
-interface. A simple value object that encapsulates the properties of a simple mail such
-as `from` and `to` (plus many others) is the `SimpleMailMessage` class. This package
-also contains a hierarchy of checked exceptions that provide a higher level of
-abstraction over the lower level mail system exceptions, with the root exception being
-`MailException`. See the {api-spring-framework}/mail/MailException.html[javadoc]
-for more information on the rich mail exception hierarchy.
-
-The `org.springframework.mail.javamail.JavaMailSender` interface adds specialized
-JavaMail features, such as MIME message support to the `MailSender` interface
-(from which it inherits). `JavaMailSender` also provides a callback interface called
-`org.springframework.mail.javamail.MimeMessagePreparator` for preparing a `MimeMessage`.
-
-
-
-[[mail-usage]]
-== Usage
-
-Assume that we have a business interface called `OrderManager`, as the following example shows:
-
-[source,java,indent=0,subs="verbatim,quotes"]
----
-	public interface OrderManager {
-
-		void placeOrder(Order order);
-
-	}
----
-
-Further assume that we have a requirement stating that an email message with an
-order number needs to be generated and sent to a customer who placed the relevant order.
-
-
-[[mail-usage-simple]]
-=== Basic `MailSender` and `SimpleMailMessage` Usage
-
-The following example shows how to use `MailSender` and `SimpleMailMessage` to send an
-email when someone places an order:
-
-[source,java,indent=0,subs="verbatim,quotes"]
----
-	import org.springframework.mail.MailException;
-	import org.springframework.mail.MailSender;
-	import org.springframework.mail.SimpleMailMessage;
-
-	public class SimpleOrderManager implements OrderManager {
-
-		private MailSender mailSender;
-		private SimpleMailMessage templateMessage;
-
-		public void setMailSender(MailSender mailSender) {
-			this.mailSender = mailSender;
-		}
-
-		public void setTemplateMessage(SimpleMailMessage templateMessage) {
-			this.templateMessage = templateMessage;
-		}
-
-		public void placeOrder(Order order) {
-
-			// Do the business calculations...
-
-			// Call the collaborators to persist the order...
-
-			// Create a thread safe "copy" of the template message and customize it
-			SimpleMailMessage msg = new SimpleMailMessage(this.templateMessage);
-			msg.setTo(order.getCustomer().getEmailAddress());
-			msg.setText(
-				"Dear " + order.getCustomer().getFirstName()
-					+ order.getCustomer().getLastName()
-					+ ", thank you for placing order. Your order number is "
-					+ order.getOrderNumber());
-			try {
-				this.mailSender.send(msg);
-			}
-			catch (MailException ex) {
-				// simply log it and go on...
-				System.err.println(ex.getMessage());
-			}
-		}
-
-	}
----
-
-The following example shows the bean definitions for the preceding code:
-
-[source,xml,indent=0,subs="verbatim,quotes"]
----
-	<bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
-		<property name="host" value="mail.mycompany.example"/>
-	</bean>
-
-	<!-- this is a template message that we can pre-load with default state -->
-	<bean id="templateMessage" class="org.springframework.mail.SimpleMailMessage">
-		<property name="from" value="customerservice@mycompany.example"/>
-		<property name="subject" value="Your order"/>
-	</bean>
-
-	<bean id="orderManager" class="com.mycompany.businessapp.support.SimpleOrderManager">
-		<property name="mailSender" ref="mailSender"/>
-		<property name="templateMessage" ref="templateMessage"/>
-	</bean>
----
-
-
-[[mail-usage-mime]]
-=== Using `JavaMailSender` and `MimeMessagePreparator`
-
-This section describes another implementation of `OrderManager` that uses the `MimeMessagePreparator`
-callback interface. In the following example, the `mailSender` property is of type
-`JavaMailSender` so that we are able to use the JavaMail `MimeMessage` class:
-
-[source,java,indent=0,subs="verbatim,quotes"]
----
-	import jakarta.mail.Message;
-	import jakarta.mail.MessagingException;
-	import jakarta.mail.internet.InternetAddress;
-	import jakarta.mail.internet.MimeMessage;
-
-	import jakarta.mail.internet.MimeMessage;
-	import org.springframework.mail.MailException;
-	import org.springframework.mail.javamail.JavaMailSender;
-	import org.springframework.mail.javamail.MimeMessagePreparator;
-
-	public class SimpleOrderManager implements OrderManager {
-
-		private JavaMailSender mailSender;
-
-		public void setMailSender(JavaMailSender mailSender) {
-			this.mailSender = mailSender;
-		}
-
-		public void placeOrder(final Order order) {
-			// Do the business calculations...
-			// Call the collaborators to persist the order...
-
-			MimeMessagePreparator preparator = new MimeMessagePreparator() {
-				public void prepare(MimeMessage mimeMessage) throws Exception {
-					mimeMessage.setRecipient(Message.RecipientType.TO,
-							new InternetAddress(order.getCustomer().getEmailAddress()));
-					mimeMessage.setFrom(new InternetAddress("mail@mycompany.example"));
-					mimeMessage.setText("Dear " + order.getCustomer().getFirstName() + " " +
-							order.getCustomer().getLastName() + ", thanks for your order. " +
-							"Your order number is " + order.getOrderNumber() + ".");
-				}
-			};
-
-			try {
-				this.mailSender.send(preparator);
-			}
-			catch (MailException ex) {
-				// simply log it and go on...
-				System.err.println(ex.getMessage());
-			}
-		}
-
-	}
----
-
-NOTE: The mail code is a crosscutting concern and could well be a candidate for
-refactoring into a <<core.adoc#aop, custom Spring AOP aspect>>, which could then
-be run at appropriate joinpoints on the `OrderManager` target.
-
-The Spring Framework's mail support ships with the standard JavaMail implementation.
-See the relevant javadoc for more information.
-
-
-
-[[mail-javamail-mime]]
-== Using the JavaMail `MimeMessageHelper`
-
-A class that comes in pretty handy when dealing with JavaMail messages is
-`org.springframework.mail.javamail.MimeMessageHelper`, which shields you from
-having to use the verbose JavaMail API. Using the `MimeMessageHelper`, it is
-pretty easy to create a `MimeMessage`, as the following example shows:
-
-[source,java,indent=0,subs="verbatim,quotes"]
----
-	// of course you would use DI in any real-world cases
-	JavaMailSenderImpl sender = new JavaMailSenderImpl();
-	sender.setHost("mail.host.com");
-
-	MimeMessage message = sender.createMimeMessage();
-	MimeMessageHelper helper = new MimeMessageHelper(message);
-	helper.setTo("test@host.com");
-	helper.setText("Thank you for ordering!");
-
-	sender.send(message);
----
-
-
-[[mail-javamail-mime-attachments]]
-=== Sending Attachments and Inline Resources
-
-Multipart email messages allow for both attachments and inline resources. Examples of
-inline resources include an image or a stylesheet that you want to use in your message but
-that you do not want displayed as an attachment.
-
-[[mail-javamail-mime-attachments-attachment]]
-==== Attachments
-
-The following example shows you how to use the `MimeMessageHelper` to send an email
-with a single JPEG image attachment:
-
-[source,java,indent=0,subs="verbatim,quotes"]
----
-	JavaMailSenderImpl sender = new JavaMailSenderImpl();
-	sender.setHost("mail.host.com");
-
-	MimeMessage message = sender.createMimeMessage();
-
-	// use the true flag to indicate you need a multipart message
-	MimeMessageHelper helper = new MimeMessageHelper(message, true);
-	helper.setTo("test@host.com");
-
-	helper.setText("Check out this image!");
-
-	// let's attach the infamous windows Sample file (this time copied to c:/)
-	FileSystemResource file = new FileSystemResource(new File("c:/Sample.jpg"));
-	helper.addAttachment("CoolImage.jpg", file);
-
-	sender.send(message);
----
-
-[[mail-javamail-mime-attachments-inline]]
-==== Inline Resources
-
-The following example shows you how to use the `MimeMessageHelper` to send an email
-with an inline image:
-
-[source,java,indent=0,subs="verbatim,quotes"]
----
-	JavaMailSenderImpl sender = new JavaMailSenderImpl();
-	sender.setHost("mail.host.com");
-
-	MimeMessage message = sender.createMimeMessage();
-
-	// use the true flag to indicate you need a multipart message
-	MimeMessageHelper helper = new MimeMessageHelper(message, true);
-	helper.setTo("test@host.com");
-
-	// use the true flag to indicate the text included is HTML
-	helper.setText("<html><body><img src='cid:identifier1234'></body></html>", true);
-
-	// let's include the infamous windows Sample file (this time copied to c:/)
-	FileSystemResource res = new FileSystemResource(new File("c:/Sample.jpg"));
-	helper.addInline("identifier1234", res);
-
-	sender.send(message);
----
-
-WARNING: Inline resources are added to the `MimeMessage` by using the specified `Content-ID`
-(`identifier1234` in the above example). The order in which you add the text
-and the resource are very important. Be sure to first add the text and then
-the resources. If you are doing it the other way around, it does not work.
-
-
-[[mail-templates]]
-=== Creating Email Content by Using a Templating Library
-
-The code in the examples shown in the previous sections explicitly created the content of the email message,
-by using methods calls such as `message.setText(..)`. This is fine for simple cases, and it
-is okay in the context of the aforementioned examples, where the intent was to show you
-the very basics of the API.
-
-In your typical enterprise application, though, developers often do not create the content
-of email messages by using the previously shown approach for a number of reasons:
-
-* Creating HTML-based email content in Java code is tedious and error prone.
-* There is no clear separation between display logic and business logic.
-* Changing the display structure of the email content requires writing Java code,
-  recompiling, redeploying, and so on.
-
-Typically, the approach taken to address these issues is to use a template library (such
-as FreeMarker) to define the display structure of email content. This leaves your code
-tasked only with creating the data that is to be rendered in the email template and
-sending the email. It is definitely a best practice when the content of your email messages
-becomes even moderately complex, and, with the Spring Framework's support classes for
-FreeMarker, it becomes quite easy to do.

-[[integration.observability]]
-= Observability Support
-
-Micrometer defines an https://micrometer.io/docs/observation[Observation concept that enables both Metrics and Traces] in applications.
-Metrics support offers a way to create timers, gauges or counters for collecting statistics about the runtime behavior of your application.
-Metrics can help you to track error rates, usage patterns, performance and more.
-Traces provide a holistic view of an entire system, crossing application boundaries; you can zoom in on particular user requests and follow their entire completion across applications.
-
-Spring Framework instruments various parts of its own codebase to publish observations if an `ObservationRegistry` is configured.
-You can learn more about {docs-spring-boot}/html/actuator.html#actuator.metrics[configuring the observability infrastructure in Spring Boot].
-
-[[integration.observability.concepts]]
-== Micrometer Observation concepts
-
-If you are not familiar with Micrometer Observation, here's a quick summary of the new concepts you should know about.
-
-* `Observation` is the actual recording of something happening in your application. This is processed by `ObservationHandler` implementations to produce metrics or traces.
-* Each observation has a corresponding `ObservationContext` implementation; this type holds all the relevant information for extracting metadata for it.
-  In the case of an HTTP server observation, the context implementation could hold the HTTP request, the HTTP response, any Exception thrown during processing...
-* Each `Observation` holds `KeyValues` metadata. In the case of a server HTTP observation, this could be the HTTP request method, the HTTP response status...
-  This metadata is contributed by `ObservationConvention` implementations which should declare the type of `ObservationContext` they support.
-* `KeyValues` are said to be "low cardinality" if there is a low, bounded number of possible values for the `KeyValue` tuple (HTTP method is a good example).
-  Low cardinality values are contributed to metrics only.
-  High cardinality values are on the other hand unbounded (for example, HTTP request URIs) and are only contributed to Traces.
-* An `ObservationDocumentation` documents all observations in a particular domain, listing the expected key names and their meaning.
-
-
-[[integration.observability.config]]
-== Configuring Observations
-
-Global configuration options are available at the `ObservationRegistry#observationConfig()` level.
-Each instrumented component will provide two extension points:
-
-* setting the `ObservationRegistry`; if not set, observations will not be recorded and will be no-ops
-* providing a custom `ObservationConvention` to change the default observation name and extracted `KeyValues`
-
-
-[[integration.observability.config.conventions]]
-=== Using custom Observation conventions
-
-Let's take the example of the Spring MVC "http.server.requests" metrics instrumentation with the `ServerHttpObservationFilter`.
-This observation is using a `ServerRequestObservationConvention` with a `ServerRequestObservationContext`; custom conventions can be configured on the Servlet filter.
-If you would like to customize the metadata produced with the observation, you can extend the `DefaultServerRequestObservationConvention` for your requirements:
-
-include::code:ExtendedServerRequestObservationConvention[]
-
-If you want full control, you can then implement the entire convention contract for the observation you're interested in:
-
-include::code:CustomServerRequestObservationConvention[]
-
-You can also achieve similar goals using a custom `ObservationFilter` - adding or removing key values for an observation.
-Filters do not replace the default convention and are used as a post-processing component.
-
-include::code:ServerRequestObservationFilter[]
-
-You can configure `ObservationFilter` instances on the `ObservationRegistry`.
-
-
-[[integration.observability.http-server]]
-== HTTP Server instrumentation
-
-HTTP server exchanges observations are created with the name `"http.server.requests"` for Servlet and Reactive applications.

-= REST Clients
-
-The Spring Framework provides the following choices for making calls to REST endpoints:
-
-* <<rest-webclient>> - non-blocking, reactive client w fluent API.
-* <<rest-resttemplate>> - synchronous client with template method API.
-* <<rest-http-interface>> - annotated interface with generated, dynamic proxy implementation.
-
-
-[[rest-webclient]]
-== `WebClient`
-
-`WebClient` is a non-blocking, reactive client to perform HTTP requests. It was
-introduced in 5.0 and offers an alternative to the `RestTemplate`, with support for
-synchronous, asynchronous, and streaming scenarios.
-
-`WebClient` supports the following:
-
-* Non-blocking I/O.
-* Reactive Streams back pressure.
-* High concurrency with fewer hardware resources.
-* Functional-style, fluent API that takes advantage of Java 8 lambdas.
-* Synchronous and asynchronous interactions.
-* Streaming up to or streaming down from a server.
-
-See <<web-reactive.adoc#webflux-client, WebClient>> for more details.
-
-
-
-
-[[rest-resttemplate]]
-== `RestTemplate`
-
-The `RestTemplate` provides a higher level API over HTTP client libraries. It makes it
-easy to invoke REST endpoints in a single line. It exposes the following groups of
-overloaded methods:
-
-NOTE: `RestTemplate` is in maintenance mode, with only requests for minor
-changes and bugs to be accepted. Please, consider using the
-<<web-reactive.adoc#webflux-client, WebClient>> instead.
-
-[[rest-overview-of-resttemplate-methods-tbl]]
-.RestTemplate methods
-[cols="1,3"]
-|===
-| Method group | Description
-
-| `getForObject`
-| Retrieves a representation via GET.
-
-| `getForEntity`
-| Retrieves a `ResponseEntity` (that is, status, headers, and body) by using GET.
-
-| `headForHeaders`
-| Retrieves all headers for a resource by using HEAD.
-
-| `postForLocation`
-| Creates a new resource by using POST and returns the `Location` header from the response.
-
-| `postForObject`
-| Creates a new resource by using POST and returns the representation from the response.
-
-| `postForEntity`
-| Creates a new resource by using POST and returns the representation from the response.
-
-| `put`
-| Creates or updates a resource by using PUT.
-
-| `patchForObject`
-| Updates a resource by using PATCH and returns the representation from the response.
-Note that the JDK `HttpURLConnection` does not support `PATCH`, but Apache
-HttpComponents and others do.
-
-| `delete`
-| Deletes the resources at the specified URI by using DELETE.
-
-| `optionsForAllow`
-| Retrieves allowed HTTP methods for a resource by using ALLOW.
-
-| `exchange`
-| More generalized (and less opinionated) version of the preceding methods that provides extra
-flexibility when needed. It accepts a `RequestEntity` (including HTTP method, URL, headers,
-and body as input) and returns a `ResponseEntity`.
-
-These methods allow the use of `ParameterizedTypeReference` instead of `Class` to specify
-a response type with generics.
-
-| `execute`
-| The most generalized way to perform a request, with full control over request
-preparation and response extraction through callback interfaces.
-
-|===
-
-[[rest-resttemplate-create]]
-=== Initialization
-
-The default constructor uses `java.net.HttpURLConnection` to perform requests. You can
-switch to a different HTTP library with an implementation of `ClientHttpRequestFactory`.
-There is built-in support for the following:
-
-* Apache HttpComponents
-* Netty
-* OkHttp
-
-For example, to switch to Apache HttpComponents, you can use the following:
-
-[source,java,indent=0,subs="verbatim,quotes"]
----
-	RestTemplate template = new RestTemplate(new HttpComponentsClientHttpRequestFactory());
----
-
-Each `ClientHttpRequestFactory` exposes configuration options specific to the underlying
-HTTP client library -- for example, for credentials, connection pooling, and other details.
-
-TIP: Note that the `java.net` implementation for HTTP requests can raise an exception when
-accessing the status of a response that represents an error (such as 401). If this is an
-issue, switch to another HTTP client library.
-
-[[rest-resttemplate-uri]]
-==== URIs
-
-Many of the `RestTemplate` methods accept a URI template and URI template variables,
-either as a `String` variable argument, or as `Map<String,String>`.
-
-The following example uses a `String` variable argument:
-
-[source,java,indent=0,subs="verbatim,quotes"]
----
-	String result = restTemplate.getForObject(
-			"https://example.com/hotels/{hotel}/bookings/{booking}", String.class, "42", "21");
----
-
-The following example uses a `Map<String, String>`:
-
-[source,java,indent=0,subs="verbatim,quotes"]
----
-	Map<String, String> vars = Collections.singletonMap("hotel", "42");
-
-	String result = restTemplate.getForObject(
-			"https://example.com/hotels/{hotel}/rooms/{hotel}", String.class, vars);
----
-
-Keep in mind URI templates are automatically encoded, as the following example shows:
-
-[source,java,indent=0,subs="verbatim,quotes"]
----
-	restTemplate.getForObject("https://example.com/hotel list", String.class);
-
-	// Results in request to "https://example.com/hotel%20list"
----
-
-You can use the `uriTemplateHandler` property of `RestTemplate` to customize how URIs
-are encoded. Alternatively, you can prepare a `java.net.URI` and pass it into one of
-the `RestTemplate` methods that accepts a `URI`.
-
-For more details on working with and encoding URIs, see <<web.adoc#mvc-uri-building, URI Links>>.
-
-[[rest-template-headers]]
-==== Headers
-
-You can use the `exchange()` methods to specify request headers, as the following example shows:
-
-[source,java,indent=0,subs="verbatim,quotes"]
----
-	String uriTemplate = "https://example.com/hotels/{hotel}";
-	URI uri = UriComponentsBuilder.fromUriString(uriTemplate).build(42);
-
-	RequestEntity<Void> requestEntity = RequestEntity.get(uri)
-			.header("MyRequestHeader", "MyValue")
-			.build();
-
-	ResponseEntity<String> response = template.exchange(requestEntity, String.class);
-
-	String responseHeader = response.getHeaders().getFirst("MyResponseHeader");
-	String body = response.getBody();
----
-
-You can obtain response headers through many `RestTemplate` method variants that return
-`ResponseEntity`.
-
-[[rest-template-body]]
-=== Body
-
-Objects passed into and returned from `RestTemplate` methods are converted to and from raw
-content with the help of an `HttpMessageConverter`.
-
-On a POST, an input object is serialized to the request body, as the following example shows:
-
----
-URI location = template.postForLocation("https://example.com/people", person);
----
-
-You need not explicitly set the Content-Type header of the request. In most cases,
-you can find a compatible message converter based on the source `Object` type, and the chosen
-message converter sets the content type accordingly. If necessary, you can use the
-`exchange` methods to explicitly provide the `Content-Type` request header, and that, in
-turn, influences what message converter is selected.
-
-On a GET, the body of the response is deserialized to an output `Object`, as the following example shows:
-
----
-Person person = restTemplate.getForObject("https://example.com/people/{id}", Person.class, 42);
----
-
-The `Accept` header of the request does not need to be explicitly set. In most cases,
-a compatible message converter can be found based on the expected response type, which
-then helps to populate the `Accept` header. If necessary, you can use the `exchange`
-methods to provide the `Accept` header explicitly.
-
-By default, `RestTemplate` registers all built-in
-<<rest-message-conversion, message converters>>, depending on classpath checks that help
-to determine what optional conversion libraries are present. You can also set the message
-converters to use explicitly.
-
-[[rest-message-conversion]]
-==== Message Conversion
-[.small]#<<web-reactive.adoc#webflux-codecs, WebFlux>>#
-
-The `spring-web` module contains the `HttpMessageConverter` contract for reading and
-writing the body of HTTP requests and responses through `InputStream` and `OutputStream`.
-`HttpMessageConverter` instances are used on the client side (for example, in the `RestTemplate`) and
-on the server side (for example, in Spring MVC REST controllers).
-
-Concrete implementations for the main media (MIME) types are provided in the framework
-and are, by default, registered with the `RestTemplate` on the client side and with
-`RequestMappingHandlerAdapter` on the server side (see
-<<web.adoc#mvc-config-message-converters, Configuring Message Converters>>).
-
-The implementations of `HttpMessageConverter` are described in the following sections.
-For all converters, a default media type is used, but you can override it by setting the
-`supportedMediaTypes` bean property. The following table describes each implementation:
-
-[[rest-message-converters-tbl]]
-.HttpMessageConverter Implementations
-[cols="1,3"]
-|===
-| MessageConverter | Description
-
-| `StringHttpMessageConverter`
-| An `HttpMessageConverter` implementation that can read and write `String` instances from the HTTP
-request and response. By default, this converter supports all text media types
-(`text/{asterisk}`) and writes with a `Content-Type` of `text/plain`.
-
-| `FormHttpMessageConverter`
-| An `HttpMessageConverter` implementation that can read and write form data from the HTTP
-request and response. By default, this converter reads and writes the
-`application/x-www-form-urlencoded` media type. Form data is read from and written into a
-`MultiValueMap<String, String>`. The converter can also write (but not read) multipart
-data read from a `MultiValueMap<String, Object>`. By default, `multipart/form-data` is
-supported. As of Spring Framework 5.2, additional multipart subtypes can be supported for
-writing form data. Consult the javadoc for `FormHttpMessageConverter` for further details.
-
-| `ByteArrayHttpMessageConverter`
-| An `HttpMessageConverter` implementation that can read and write byte arrays from the
-HTTP request and response. By default, this converter supports all media types (`{asterisk}/{asterisk}`)
-and writes with a `Content-Type` of `application/octet-stream`. You can override this
-by setting the `supportedMediaTypes` property and overriding `getContentType(byte[])`.
-
-| `MarshallingHttpMessageConverter`
-| An `HttpMessageConverter` implementation that can read and write XML by using Spring's
-`Marshaller` and `Unmarshaller` abstractions from the `org.springframework.oxm` package.
-This converter requires a `Marshaller` and `Unmarshaller` before it can be used. You can inject these
-through constructor or bean properties. By default, this converter supports
-`text/xml` and `application/xml`.
-
-| `MappingJackson2HttpMessageConverter`
-| An `HttpMessageConverter` implementation that can read and write JSON by using Jackson's
-`ObjectMapper`. You can customize JSON mapping as needed through the use of Jackson's
-provided annotations. When you need further control (for cases where custom JSON
-serializers/deserializers need to be provided for specific types), you can inject a custom `ObjectMapper`
-through the `ObjectMapper` property. By default, this
-converter supports `application/json`.
-
-| `MappingJackson2XmlHttpMessageConverter`
-| An `HttpMessageConverter` implementation that can read and write XML by using
-https://github.com/FasterXML/jackson-dataformat-xml[Jackson XML] extension's
-`XmlMapper`. You can customize XML mapping as needed through the use of JAXB
-or Jackson's provided annotations. When you need further control (for cases where custom XML
-serializers/deserializers need to be provided for specific types), you can inject a custom `XmlMapper`
-through the `ObjectMapper` property. By default, this
-converter supports `application/xml`.
-
-| `SourceHttpMessageConverter`
-| An `HttpMessageConverter` implementation that can read and write
-`javax.xml.transform.Source` from the HTTP request and response. Only `DOMSource`,
-`SAXSource`, and `StreamSource` are supported. By default, this converter supports
-`text/xml` and `application/xml`.
-
-| `BufferedImageHttpMessageConverter`
-| An `HttpMessageConverter` implementation that can read and write
-`java.awt.image.BufferedImage` from the HTTP request and response. This converter reads
-and writes the media type supported by the Java I/O API.
-
-|===
-
-[[rest-template-jsonview]]
-=== Jackson JSON Views
-
-You can specify a https://www.baeldung.com/jackson-json-view-annotation[Jackson JSON View]
-to serialize only a subset of the object properties, as the following example shows:
-
-[source,java,indent=0,subs="verbatim,quotes"]
----
-	MappingJacksonValue value = new MappingJacksonValue(new User("eric", "7!jd#h23"));
-	value.setSerializationView(User.WithoutPasswordView.class);
-
-	RequestEntity<MappingJacksonValue> requestEntity =
-		RequestEntity.post(new URI("https://example.com/user")).body(value);
-
-	ResponseEntity<String> response = template.exchange(requestEntity, String.class);
----
-
-[[rest-template-multipart]]
-=== Multipart
-
-To send multipart data, you need to provide a `MultiValueMap<String, Object>` whose values
-may be an `Object` for part content, a `Resource` for a file part, or an `HttpEntity` for
-part content with headers. For example:
-
-[source,java,indent=0,subs="verbatim,quotes"]
----
-	MultiValueMap<String, Object> parts = new LinkedMultiValueMap<>();
-
-	parts.add("fieldPart", "fieldValue");
-	parts.add("filePart", new FileSystemResource("...logo.png"));
-	parts.add("jsonPart", new Person("Jason"));
-
-	HttpHeaders headers = new HttpHeaders();
-	headers.setContentType(MediaType.APPLICATION_XML);
-	parts.add("xmlPart", new HttpEntity<>(myBean, headers));
----
-
-In most cases, you do not have to specify the `Content-Type` for each part. The content
-type is determined automatically based on the `HttpMessageConverter` chosen to serialize
-it or, in the case of a `Resource` based on the file extension. If necessary, you can
-explicitly provide the `MediaType` with an `HttpEntity` wrapper.
-
-Once the `MultiValueMap` is ready, you can pass it to the `RestTemplate`, as show below:
-
-[source,java,indent=0,subs="verbatim,quotes"]
----
-	MultiValueMap<String, Object> parts = ...;
-	template.postForObject("https://example.com/upload", parts, Void.class);
----
-
-If the `MultiValueMap` contains at least one non-`String` value, the `Content-Type` is set
-to `multipart/form-data` by the `FormHttpMessageConverter`. If the `MultiValueMap` has
-`String` values the `Content-Type` is defaulted to `application/x-www-form-urlencoded`.
-If necessary the `Content-Type` may also be set explicitly.
-
-
-[[rest-http-interface]]
-== HTTP Interface
-
-The Spring Framework lets you define an HTTP service as a Java interface with annotated
-methods for HTTP exchanges. You can then generate a proxy that implements this interface
-and performs the exchanges. This helps to simplify HTTP remote access which often
-involves a facade that wraps the details of using the underlying HTTP client.
-
-One, declare an interface with `@HttpExchange` methods:
-
-[source,java,indent=0,subs="verbatim,quotes"]
----
-	interface RepositoryService {
-
-		@GetExchange("/repos/{owner}/{repo}")
-		Repository getRepository(@PathVariable String owner, @PathVariable String repo);
-
-		// more HTTP exchange methods...
-
-	}

-= Task Execution and Scheduling
-
-The Spring Framework provides abstractions for the asynchronous execution and scheduling of
-tasks with the `TaskExecutor` and `TaskScheduler` interfaces, respectively. Spring also
-features implementations of those interfaces that support thread pools or delegation to
-CommonJ within an application server environment. Ultimately, the use of these
-implementations behind the common interfaces abstracts away the differences between Java
-SE 5, Java SE 6, and Jakarta EE environments.
-
-Spring also features integration classes to support scheduling with the `Timer`
-(part of the JDK since 1.3) and the Quartz Scheduler ( https://www.quartz-scheduler.org/[]).
-You can set up both of those schedulers by using a `FactoryBean` with optional references to
-`Timer` or `Trigger` instances, respectively. Furthermore, a convenience class for both
-the Quartz Scheduler and the `Timer` is available that lets you invoke a method of
-an existing target object (analogous to the normal `MethodInvokingFactoryBean`
-operation).
-
-
-
-[[scheduling-task-executor]]
-== The Spring `TaskExecutor` Abstraction
-
-Executors are the JDK name for the concept of thread pools. The "`executor`" naming is
-due to the fact that there is no guarantee that the underlying implementation is
-actually a pool. An executor may be single-threaded or even synchronous. Spring's
-abstraction hides implementation details between the Java SE and Jakarta EE environments.
-
-Spring's `TaskExecutor` interface is identical to the `java.util.concurrent.Executor`
-interface. In fact, originally, its primary reason for existence was to abstract away
-the need for Java 5 when using thread pools. The interface has a single method
-(`execute(Runnable task)`) that accepts a task for execution based on the semantics
-and configuration of the thread pool.
-
-The `TaskExecutor` was originally created to give other Spring components an abstraction
-for thread pooling where needed. Components such as the `ApplicationEventMulticaster`,
-JMS's `AbstractMessageListenerContainer`, and Quartz integration all use the
-`TaskExecutor` abstraction to pool threads. However, if your beans need thread pooling
-behavior, you can also use this abstraction for your own needs.
-
-
-[[scheduling-task-executor-types]]
-=== `TaskExecutor` Types
-
-Spring includes a number of pre-built implementations of `TaskExecutor`.
-In all likelihood, you should never need to implement your own.
-The variants that Spring provides are as follows:
-
-* `SyncTaskExecutor`:
-  This implementation does not run invocations asynchronously. Instead, each
-  invocation takes place in the calling thread. It is primarily used in situations
-  where multi-threading is not necessary, such as in simple test cases.
-* `SimpleAsyncTaskExecutor`:
-  This implementation does not reuse any threads. Rather, it starts up a new thread
-  for each invocation. However, it does support a concurrency limit that blocks
-  any invocations that are over the limit until a slot has been freed up. If you
-  are looking for true pooling, see `ThreadPoolTaskExecutor`, later in this list.
-* `ConcurrentTaskExecutor`:
-  This implementation is an adapter for a `java.util.concurrent.Executor` instance.
-  There is an alternative (`ThreadPoolTaskExecutor`) that exposes the `Executor`
-  configuration parameters as bean properties. There is rarely a need to use
-  `ConcurrentTaskExecutor` directly. However, if the `ThreadPoolTaskExecutor` is not
-  flexible enough for your needs, `ConcurrentTaskExecutor` is an alternative.
-* `ThreadPoolTaskExecutor`:
-  This implementation is most commonly used. It exposes bean properties for
-  configuring a `java.util.concurrent.ThreadPoolExecutor` and wraps it in a `TaskExecutor`.
-  If you need to adapt to a different kind of `java.util.concurrent.Executor`, we
-  recommend that you use a `ConcurrentTaskExecutor` instead.
-* `DefaultManagedTaskExecutor`:
-  This implementation uses a JNDI-obtained `ManagedExecutorService` in a JSR-236
-  compatible runtime environment (such as a Jakarta EE application server),
-  replacing a CommonJ WorkManager for that purpose.
-
-
-[[scheduling-task-executor-usage]]
-=== Using a `TaskExecutor`
-
-Spring's `TaskExecutor` implementations are used as simple JavaBeans. In the following example,
-we define a bean that uses the `ThreadPoolTaskExecutor` to asynchronously print
-out a set of messages:
-
-[source,java,indent=0,subs="verbatim,quotes"]
----
-	import org.springframework.core.task.TaskExecutor;
-
-	public class TaskExecutorExample {
-
-		private class MessagePrinterTask implements Runnable {
-
-			private String message;
-
-			public MessagePrinterTask(String message) {
-				this.message = message;
-			}
-
-			public void run() {
-				System.out.println(message);
-			}
-		}
-
-		private TaskExecutor taskExecutor;
-
-		public TaskExecutorExample(TaskExecutor taskExecutor) {
-			this.taskExecutor = taskExecutor;
-		}
-
-		public void printMessages() {
-			for(int i = 0; i < 25; i++) {
-				taskExecutor.execute(new MessagePrinterTask("Message" + i));
-			}
-		}
-	}
----
-
-As you can see, rather than retrieving a thread from the pool and executing it yourself,
-you add your `Runnable` to the queue. Then the `TaskExecutor` uses its internal rules to
-decide when the task gets run.
-
-To configure the rules that the `TaskExecutor` uses, we expose simple bean properties:
-
-[source,xml,indent=0,subs="verbatim,quotes"]
----
-	<bean id="taskExecutor" class="org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor">
-		<property name="corePoolSize" value="5"/>
-		<property name="maxPoolSize" value="10"/>
-		<property name="queueCapacity" value="25"/>
-	</bean>
-
-	<bean id="taskExecutorExample" class="TaskExecutorExample">
-		<constructor-arg ref="taskExecutor"/>
-	</bean>
----
-
-
-
-[[scheduling-task-scheduler]]
-== The Spring `TaskScheduler` Abstraction
-
-In addition to the `TaskExecutor` abstraction, Spring 3.0 introduced a `TaskScheduler`
-with a variety of methods for scheduling tasks to run at some point in the future.
-The following listing shows the `TaskScheduler` interface definition:
-
-[source,java,indent=0,subs="verbatim,quotes"]
----
-	public interface TaskScheduler {
-
-		ScheduledFuture schedule(Runnable task, Trigger trigger);
-
-		ScheduledFuture schedule(Runnable task, Instant startTime);
-
-		ScheduledFuture scheduleAtFixedRate(Runnable task, Instant startTime, Duration period);
-
-		ScheduledFuture scheduleAtFixedRate(Runnable task, Duration period);
-
-		ScheduledFuture scheduleWithFixedDelay(Runnable task, Instant startTime, Duration delay);
-
-		ScheduledFuture scheduleWithFixedDelay(Runnable task, Duration delay);
-
----
-
-The simplest method is the one named `schedule` that takes only a `Runnable` and an `Instant`.
-That causes the task to run once after the specified time. All of the other methods
-are capable of scheduling tasks to run repeatedly. The fixed-rate and fixed-delay
-methods are for simple, periodic execution, but the method that accepts a `Trigger` is
-much more flexible.
-
-
-[[scheduling-trigger-interface]]
-=== `Trigger` Interface
-
-The `Trigger` interface is essentially inspired by JSR-236 which, as of Spring 3.0,
-was not yet officially implemented. The basic idea of the `Trigger` is that execution
-times may be determined based on past execution outcomes or even arbitrary conditions.
-If these determinations do take into account the outcome of the preceding execution,
-that information is available within a `TriggerContext`. The `Trigger` interface itself
-is quite simple, as the following listing shows:
-
-[source,java,indent=0,subs="verbatim,quotes"]
----
-	public interface Trigger {
-
-		Date nextExecutionTime(TriggerContext triggerContext);
-	}
----
-
-The `TriggerContext` is the most important part. It encapsulates all of
-the relevant data and is open for extension in the future, if necessary. The
-`TriggerContext` is an interface (a `SimpleTriggerContext` implementation is used by
-default). The following listing shows the available methods for `Trigger` implementations.
-
-[source,java,indent=0,subs="verbatim,quotes"]
----
-	public interface TriggerContext {
-
-		Date lastScheduledExecutionTime();
-
-		Date lastActualExecutionTime();
-
-		Date lastCompletionTime();
-	}
----
-
-
-[[scheduling-trigger-implementations]]
-=== `Trigger` Implementations
-
-Spring provides two implementations of the `Trigger` interface. The most interesting one
-is the `CronTrigger`. It enables the scheduling of tasks based on
-<<scheduling-cron-expression,cron expressions>>.
-For example, the following task is scheduled to run 15 minutes past each hour but only
-during the 9-to-5 "`business hours`" on weekdays:
-
-[source,java,indent=0]
-[subs="verbatim"]
----
-	scheduler.schedule(task, new CronTrigger("0 15 9-17 * * MON-FRI"));
----
-
-The other implementation is a `PeriodicTrigger` that accepts a fixed
-period, an optional initial delay value, and a boolean to indicate whether the period
-should be interpreted as a fixed-rate or a fixed-delay. Since the `TaskScheduler`
-interface already defines methods for scheduling tasks at a fixed rate or with a
-fixed delay, those methods should be used directly whenever possible. The value of the
-`PeriodicTrigger` implementation is that you can use it within components that rely on
-the `Trigger` abstraction. For example, it may be convenient to allow periodic triggers,
-cron-based triggers, and even custom trigger implementations to be used interchangeably.
-Such a component could take advantage of dependency injection so that you can configure such `Triggers`
-externally and, therefore, easily modify or extend them.
-
-
-[[scheduling-task-scheduler-implementations]]
-=== `TaskScheduler` implementations
-
-As with Spring's `TaskExecutor` abstraction, the primary benefit of the `TaskScheduler`
-arrangement is that an application's scheduling needs are decoupled from the deployment
-environment. This abstraction level is particularly relevant when deploying to an
-application server environment where threads should not be created directly by the
-application itself. For such scenarios, Spring provides a `TimerManagerTaskScheduler`
-that delegates to a CommonJ `TimerManager` on WebLogic or WebSphere as well as a more recent
-`DefaultManagedTaskScheduler` that delegates to a JSR-236 `ManagedScheduledExecutorService`
-in a Jakarta EE environment. Both are typically configured with a JNDI lookup.
-
-Whenever external thread management is not a requirement, a simpler alternative is
-a local `ScheduledExecutorService` setup within the application, which can be adapted
-through Spring's `ConcurrentTaskScheduler`. As a convenience, Spring also provides a
-`ThreadPoolTaskScheduler`, which internally delegates to a `ScheduledExecutorService`
-to provide common bean-style configuration along the lines of `ThreadPoolTaskExecutor`.
-These variants work perfectly fine for locally embedded thread pool setups in lenient
-application server environments, as well -- in particular on Tomcat and Jetty.
-
-
-
-[[scheduling-annotation-support]]
-== Annotation Support for Scheduling and Asynchronous Execution
-
-Spring provides annotation support for both task scheduling and asynchronous method
-execution.
-
-
-[[scheduling-enable-annotation-support]]
-=== Enable Scheduling Annotations
-
-To enable support for `@Scheduled` and `@Async` annotations, you can add `@EnableScheduling` and
-`@EnableAsync` to one of your `@Configuration` classes, as the following example shows:
-
-[source,java,indent=0,subs="verbatim,quotes"]
----
-	@Configuration
-	@EnableAsync
-	@EnableScheduling
-	public class AppConfig {
-	}
----
-
-You can pick and choose the relevant annotations for your application. For example,
-if you need only support for `@Scheduled`, you can omit `@EnableAsync`. For more
-fine-grained control, you can additionally implement the `SchedulingConfigurer`
-interface, the `AsyncConfigurer` interface, or both. See the
-{api-spring-framework}/scheduling/annotation/SchedulingConfigurer.html[`SchedulingConfigurer`]
-and {api-spring-framework}/scheduling/annotation/AsyncConfigurer.html[`AsyncConfigurer`]
-javadoc for full details.
-
-If you prefer XML configuration, you can use the `<task:annotation-driven>` element,
-as the following example shows:
-
-[source,xml,indent=0,subs="verbatim,quotes"]
----
-	<task:annotation-driven executor="myExecutor" scheduler="myScheduler"/>
-	<task:executor id="myExecutor" pool-size="5"/>
-	<task:scheduler id="myScheduler" pool-size="10"/>
----
-
-Note that, with the preceding XML, an executor reference is provided for handling those
-tasks that correspond to methods with the `@Async` annotation, and the scheduler
-reference is provided for managing those methods annotated with `@Scheduled`.
-
-NOTE: The default advice mode for processing `@Async` annotations is `proxy` which allows
-for interception of calls through the proxy only. Local calls within the same class
-cannot get intercepted that way. For a more advanced mode of interception, consider
-switching to `aspectj` mode in combination with compile-time or load-time weaving.
-
-
-[[scheduling-annotation-support-scheduled]]
-=== The `@Scheduled` annotation
-
-You can add the `@Scheduled` annotation to a method, along with trigger metadata. For
-example, the following method is invoked every five seconds (5000 milliseconds) with a
-fixed delay, meaning that the period is measured from the completion time of each
-preceding invocation.
-
-[source,java,indent=0,subs="verbatim,quotes"]
----
-	@Scheduled(fixedDelay = 5000)
-	public void doSomething() {
-		// something that should run periodically
-	}
----
-
-[NOTE]
-====
-By default, milliseconds will be used as the time unit for fixed delay, fixed rate, and
-initial delay values. If you would like to use a different time unit such as seconds or
-minutes, you can configure this via the `timeUnit` attribute in `@Scheduled`.
-
-For example, the previous example can also be written as follows.
-
-[source,java,indent=0,subs="verbatim,quotes"]
----
-	@Scheduled(fixedDelay = 5, timeUnit = TimeUnit.SECONDS)
-	public void doSomething() {
-		// something that should run periodically
-	}
----
-====
-
-If you need a fixed-rate execution, you can use the `fixedRate` attribute within the
-annotation. The following method is invoked every five seconds (measured between the
-successive start times of each invocation).
-
-[source,java,indent=0,subs="verbatim,quotes"]
----
-	@Scheduled(fixedRate = 5, timeUnit = TimeUnit.SECONDS)
-	public void doSomething() {
-		// something that should run periodically
-	}
----
-
-For fixed-delay and fixed-rate tasks, you can specify an initial delay by indicating the
-amount of time to wait before the first execution of the method, as the following
-`fixedRate` example shows.
-
-[source,java,indent=0,subs="verbatim,quotes"]
----
-	@Scheduled(initialDelay = 1000, fixedRate = 5000)
-	public void doSomething() {
-		// something that should run periodically
-	}
----
-
-If simple periodic scheduling is not expressive enough, you can provide a
-<<scheduling-cron-expression,cron expression>>.
-The following example runs only on weekdays:
-
-[source,java,indent=0]
-[subs="verbatim"]
----
-	@Scheduled(cron="*/5 * * * * MON-FRI")
-	public void doSomething() {
-		// something that should run on weekdays only
-	}
----
-
-TIP: You can also use the `zone` attribute to specify the time zone in which the cron
-expression is resolved.
-
-Notice that the methods to be scheduled must have void returns and must not accept any
-arguments. If the method needs to interact with other objects from the application
-context, those would typically have been provided through dependency injection.
-
-[NOTE]
-====
-As of Spring Framework 4.3, `@Scheduled` methods are supported on beans of any scope.
-
-Make sure that you are not initializing multiple instances of the same `@Scheduled`
-annotation class at runtime, unless you do want to schedule callbacks to each such
-instance. Related to this, make sure that you do not use `@Configurable` on bean
-classes that are annotated with `@Scheduled` and registered as regular Spring beans
-with the container. Otherwise, you would get double initialization (once through the
-container and once through the `@Configurable` aspect), with the consequence of each
-`@Scheduled` method being invoked twice.
-====
-
-
-[[scheduling-annotation-support-async]]
-=== The `@Async` annotation
-
-You can provide the `@Async` annotation on a method so that invocation of that method
-occurs asynchronously. In other words, the caller returns immediately upon
-invocation, while the actual execution of the method occurs in a task that has been
-submitted to a Spring `TaskExecutor`. In the simplest case, you can apply the annotation
-to a method that returns `void`, as the following example shows:
-
-[source,java,indent=0,subs="verbatim,quotes"]
----
-	@Async
-	void doSomething() {
-		// this will be run asynchronously
-	}
----
-
-Unlike the methods annotated with the `@Scheduled` annotation, these methods can expect
-arguments, because they are invoked in the "`normal`" way by callers at runtime rather
-than from a scheduled task being managed by the container. For example, the following code is
-a legitimate application of the `@Async` annotation:
-
-[source,java,indent=0,subs="verbatim,quotes"]
----
-	@Async
-	void doSomething(String s) {
-		// this will be run asynchronously
-	}
----
-
-Even methods that return a value can be invoked asynchronously. However, such methods
-are required to have a `Future`-typed return value. This still provides the benefit of
-asynchronous execution so that the caller can perform other tasks prior to calling
-`get()` on that `Future`. The following example shows how to use `@Async` on a method
-that returns a value:
-
-[source,java,indent=0,subs="verbatim,quotes"]
----
-	@Async
-	Future<String> returnSomething(int i) {
-		// this will be run asynchronously
-	}
----
-
-TIP: `@Async` methods may not only declare a regular `java.util.concurrent.Future` return type
-but also Spring's `org.springframework.util.concurrent.ListenableFuture` or, as of Spring
-4.2, JDK 8's `java.util.concurrent.CompletableFuture`, for richer interaction with the
-asynchronous task and for immediate composition with further processing steps.
-
-You can not use `@Async` in conjunction with lifecycle callbacks such as
-`@PostConstruct`. To asynchronously initialize Spring beans, you currently have to use
-a separate initializing Spring bean that then invokes the `@Async` annotated method on the
-target, as the following example shows:
-
-[source,java,indent=0,subs="verbatim,quotes"]
----
-	public class SampleBeanImpl implements SampleBean {
-
-		@Async
-		void doSomething() {
-			// ...
-		}
-
-	}
-
-	public class SampleBeanInitializer {
-
-		private final SampleBean bean;
-
-		public SampleBeanInitializer(SampleBean bean) {
-			this.bean = bean;
-		}
-
-		@PostConstruct
-		public void initialize() {
-			bean.doSomething();
-		}
-
-	}
----
-
-NOTE: There is no direct XML equivalent for `@Async`, since such methods should be designed
-for asynchronous execution in the first place, not externally re-declared to be asynchronous.
-However, you can manually set up Spring's `AsyncExecutionInterceptor` with Spring AOP,
-in combination with a custom pointcut.
-
-
-[[scheduling-annotation-support-qualification]]
-=== Executor Qualification with `@Async`
-
-By default, when specifying `@Async` on a method, the executor that is used is the
-one <<scheduling-enable-annotation-support, configured when enabling async support>>,
-i.e. the "`annotation-driven`" element if you are using XML or your `AsyncConfigurer`
-implementation, if any. However, you can use the `value` attribute of the `@Async`
-annotation when you need to indicate that an executor other than the default should be
-used when executing a given method. The following example shows how to do so:
-
-[source,java,indent=0,subs="verbatim,quotes"]
----
-	@Async("otherExecutor")
-	void doSomething(String s) {
-		// this will be run asynchronously by "otherExecutor"
-	}
----
-
-In this case, `"otherExecutor"` can be the name of any `Executor` bean in the Spring
-container, or it may be the name of a qualifier associated with any `Executor` (for example, as
-specified with the `<qualifier>` element or Spring's `@Qualifier` annotation).
-
-
-[[scheduling-annotation-support-exception]]
-=== Exception Management with `@Async`
-
-When an `@Async` method has a `Future`-typed return value, it is easy to manage
-an exception that was thrown during the method execution, as this exception is
-thrown when calling `get` on the `Future` result. With a `void` return type,
-however, the exception is uncaught and cannot be transmitted. You can provide an
-`AsyncUncaughtExceptionHandler` to handle such exceptions. The following example shows
-how to do so:
-
-[source,java,indent=0,subs="verbatim,quotes"]
----
-	public class MyAsyncUncaughtExceptionHandler implements AsyncUncaughtExceptionHandler {
-
-		@Override
-		public void handleUncaughtException(Throwable ex, Method method, Object... params) {
-			// handle exception
-		}
-	}
----
-
-By default, the exception is merely logged. You can define a custom `AsyncUncaughtExceptionHandler`
-by using `AsyncConfigurer` or the `<task:annotation-driven/>` XML element.
-
-
-
-[[scheduling-task-namespace]]
-== The `task` Namespace
-
-As of version 3.0, Spring includes an XML namespace for configuring `TaskExecutor` and
-`TaskScheduler` instances. It also provides a convenient way to configure tasks to be
-scheduled with a trigger.
-
-
-[[scheduling-task-namespace-scheduler]]
-=== The 'scheduler' Element
-
-The following element creates a `ThreadPoolTaskScheduler` instance with the
-specified thread pool size:
-
-[source,xml,indent=0,subs="verbatim,quotes"]
----
-	<task:scheduler id="scheduler" pool-size="10"/>
----
-
-The value provided for the `id` attribute is used as the prefix for thread names
-within the pool. The `scheduler` element is relatively straightforward. If you do not
-provide a `pool-size` attribute, the default thread pool has only a single thread.
-There are no other configuration options for the scheduler.
-
-
-[[scheduling-task-namespace-executor]]
-=== The `executor` Element
-
-The following creates a `ThreadPoolTaskExecutor` instance:
-
-[source,xml,indent=0,subs="verbatim,quotes"]
----
-	<task:executor id="executor" pool-size="10"/>
----
-
-As with the scheduler shown in the <<scheduling-task-namespace-scheduler, previous section>>,
-the value provided for the `id` attribute is used as the prefix for thread names within
-the pool. As far as the pool size is concerned, the `executor` element supports more
-configuration options than the `scheduler` element. For one thing, the thread pool for
-a `ThreadPoolTaskExecutor` is itself more configurable. Rather than only a single size,
-an executor's thread pool can have different values for the core and the max size.
-If you provide a single value, the executor has a fixed-size thread pool (the core and
-max sizes are the same). However, the `executor` element's `pool-size` attribute also
-accepts a range in the form of `min-max`. The following example sets a minimum value of
-`5` and a maximum value of `25`:
-
-[source,xml,indent=0,subs="verbatim,quotes"]
----
-	<task:executor
-			id="executorWithPoolSizeRange"
-			pool-size="5-25"
-			queue-capacity="100"/>
----
-
-In the preceding configuration, a `queue-capacity` value has also been provided.
-The configuration of the thread pool should also be considered in light of the
-executor's queue capacity. For the full description of the relationship between pool
-size and queue capacity, see the documentation for
-https://docs.oracle.com/javase/8/docs/api/java/util/concurrent/ThreadPoolExecutor.html[`ThreadPoolExecutor`].
-The main idea is that, when a task is submitted, the executor first tries to use a
-free thread if the number of active threads is currently less than the core size.
-If the core size has been reached, the task is added to the queue, as long as its
-capacity has not yet been reached. Only then, if the queue's capacity has been
-reached, does the executor create a new thread beyond the core size. If the max size
-has also been reached, then the executor rejects the task.
-
-By default, the queue is unbounded, but this is rarely the desired configuration,
-because it can lead to `OutOfMemoryErrors` if enough tasks are added to that queue while
-all pool threads are busy. Furthermore, if the queue is unbounded, the max size has
-no effect at all. Since the executor always tries the queue before creating a new
-thread beyond the core size, a queue must have a finite capacity for the thread pool to
-grow beyond the core size (this is why a fixed-size pool is the only sensible case
-when using an unbounded queue).
-
-Consider the case, as mentioned above, when a task is rejected. By default, when a
-task is rejected, a thread pool executor throws a `TaskRejectedException`. However,
-the rejection policy is actually configurable. The exception is thrown when using
-the default rejection policy, which is the `AbortPolicy` implementation.
-For applications where some tasks can be skipped under heavy load, you can instead
-configure either `DiscardPolicy` or `DiscardOldestPolicy`. Another option that works
-well for applications that need to throttle the submitted tasks under heavy load is
-the `CallerRunsPolicy`. Instead of throwing an exception or discarding tasks,
-that policy forces the thread that is calling the submit method to run the task itself.
-The idea is that such a caller is busy while running that task and not able to submit
-other tasks immediately. Therefore, it provides a simple way to throttle the incoming
-load while maintaining the limits of the thread pool and queue. Typically, this allows
-the executor to "`catch up`" on the tasks it is handling and thereby frees up some
-capacity on the queue, in the pool, or both. You can choose any of these options from an
-enumeration of values available for the `rejection-policy` attribute on the `executor`
-element.
-
-The following example shows an `executor` element with a number of attributes to specify
-various behaviors:
-
-[source,xml,indent=0,subs="verbatim,quotes"]
----
-	<task:executor
-			id="executorWithCallerRunsPolicy"
-			pool-size="5-25"
-			queue-capacity="100"
-			rejection-policy="CALLER_RUNS"/>
----
-
-Finally, the `keep-alive` setting determines the time limit (in seconds) for which threads
-may remain idle before being stopped. If there are more than the core number of threads
-currently in the pool, after waiting this amount of time without processing a task, excess
-threads get stopped. A time value of zero causes excess threads to stop
-immediately after executing a task without remaining follow-up work in the task queue.
-The following example sets the `keep-alive` value to two minutes:
-
-[source,xml,indent=0,subs="verbatim,quotes"]
----
-	<task:executor
-			id="executorWithKeepAlive"
-			pool-size="5-25"
-			keep-alive="120"/>
----
-
-
-[[scheduling-task-namespace-scheduled-tasks]]
-=== The 'scheduled-tasks' Element
-
-The most powerful feature of Spring's task namespace is the support for configuring
-tasks to be scheduled within a Spring Application Context. This follows an approach
-similar to other "`method-invokers`" in Spring, such as that provided by the JMS namespace
-for configuring message-driven POJOs. Basically, a `ref` attribute can point to any
-Spring-managed object, and the `method` attribute provides the name of a method to be
-invoked on that object. The following listing shows a simple example:
-
-[source,xml,indent=0,subs="verbatim,quotes"]
----
-	<task:scheduled-tasks scheduler="myScheduler">
-		<task:scheduled ref="beanA" method="methodA" fixed-delay="5000"/>
-	</task:scheduled-tasks>
-
-	<task:scheduler id="myScheduler" pool-size="10"/>
----
-
-The scheduler is referenced by the outer element, and each individual
-task includes the configuration of its trigger metadata. In the preceding example, that
-metadata defines a periodic trigger with a fixed delay indicating the number of
-milliseconds to wait after each task execution has completed. Another option is
-`fixed-rate`, indicating how often the method should be run regardless of how long
-any previous execution takes. Additionally, for both `fixed-delay` and `fixed-rate` tasks, you can specify an
-'initial-delay' parameter, indicating the number of milliseconds to wait
-before the first execution of the method. For more control, you can instead provide a `cron` attribute
-to provide a <<scheduling-cron-expression,cron expression>>.
-The following example shows these other options:
-
-[source,xml,indent=0]
-[subs="verbatim"]
----
-	<task:scheduled-tasks scheduler="myScheduler">
-		<task:scheduled ref="beanA" method="methodA" fixed-delay="5000" initial-delay="1000"/>
-		<task:scheduled ref="beanB" method="methodB" fixed-rate="5000"/>
-		<task:scheduled ref="beanC" method="methodC" cron="*/5 * * * * MON-FRI"/>
-	</task:scheduled-tasks>
-
-	<task:scheduler id="myScheduler" pool-size="10"/>
----
-
-
-
-[[scheduling-cron-expression]]
-== Cron Expressions
-
-All Spring cron expressions have to conform to the same format, whether you are using them in
-<<scheduling-annotation-support-scheduled,`@Scheduled` annotations>>,
-<<scheduling-task-namespace-scheduled-tasks,`task:scheduled-tasks` elements>>,
-or someplace else.
-A well-formed cron expression, such as `* * * * * *`, consists of six space-separated time and date
-fields, each with its own range of valid values:
-
-
-....
- ┌───────────── second (0-59)
- │ ┌───────────── minute (0 - 59)
- │ │ ┌───────────── hour (0 - 23)
- │ │ │ ┌───────────── day of the month (1 - 31)
- │ │ │ │ ┌───────────── month (1 - 12) (or JAN-DEC)
- │ │ │ │ │ ┌───────────── day of the week (0 - 7)
- │ │ │ │ │ │          (0 or 7 is Sunday, or MON-SUN)
- │ │ │ │ │ │
- * * * * * *
-....
-
-There are some rules that apply:
-
-* A field may be an asterisk (`*`), which always stands for "`first-last`".
-For the day-of-the-month or day-of-the-week fields, a question mark (`?`) may be used instead of an
-asterisk.
-* Commas (`,`) are used to separate items of a list.
-* Two numbers separated with a hyphen (`-`) express a range of numbers.
-The specified range is inclusive.
-* Following a range (or `*`) with `/` specifies the interval of the number's value through the range.
-* English names can also be used for the month and day-of-week fields.
-Use the first three letters of the particular day or month (case does not matter).
-* The day-of-month and day-of-week fields can contain an `L` character, which has a different meaning.
-** In the day-of-month field, `L` stands for _the last day of the month_.
-If followed by a negative offset (that is, `L-n`), it means _``n``th-to-last day of the month_.
-** In the day-of-week field, `L` stands for _the last day of the week_.
-If prefixed by a number or three-letter name (`dL` or `DDDL`), it means _the last day of week (`d`
-or `DDD`) in the month_.
-* The day-of-month field can be `nW`, which stands for _the nearest weekday to day of the month ``n``_.
-If `n` falls on Saturday, this yields the Friday before it.
-If `n` falls on Sunday, this yields the Monday after, which also happens if `n` is `1` and falls on
-a Saturday (that is: `1W` stands for _the first weekday of the month_).
-* If the day-of-month field is `LW`, it means _the last weekday of the month_.
-* The day-of-week field can be `d#n` (or `DDD#n`), which stands for _the ``n``th day of week `d`
-(or ``DDD``) in the month_.
-
-Here are some examples:
-
-|===
-| Cron Expression       | Meaning
-
-|`0 0 * * * *`          | top of every hour of every day
-|`*/10 * * * * *`       | every ten seconds
-| `0 0 8-10 * * *`      | 8, 9 and 10 o'clock of every day
-| `0 0 6,19 * * *`      | 6:00 AM and 7:00 PM every day
-| `0 0/30 8-10 * * *`   | 8:00, 8:30, 9:00, 9:30, 10:00 and 10:30 every day
-| `0 0 9-17 * * MON-FRI`| on the hour nine-to-five weekdays
-| `0 0 0 25 DEC ?`       | every Christmas Day at midnight
-| `0 0 0 L * *`         | last day of the month at midnight
-| `0 0 0 L-3 * *`       | third-to-last day of the month at midnight
-| `0 0 0 * * 5L`        | last Friday of the month at midnight
-| `0 0 0 * * THUL`      | last Thursday of the month at midnight
-| `0 0 0 1W * *`        | first weekday of the month at midnight
-| `0 0 0 LW * *`        | last weekday of the month at midnight
-| `0 0 0 ? * 5#2`       | the second Friday in the month at midnight
-| `0 0 0 ? * MON#1`     | the first Monday in the month at midnight
-|===
-
-=== Macros
-
-Expressions such as `0 0 * * * *` are hard for humans to parse and are, therefore, hard to fix in case of bugs.
-To improve readability, Spring supports the following macros, which represent commonly used sequences.
-You can use these macros instead of the six-digit value, thus: `@Scheduled(cron = "@hourly")`.
-
-|===
-|Macro                          | Meaning
-
-| `@yearly` (or `@annually`)    | once a year (`0 0 0 1 1 *`)
-| `@monthly`                    | once a month (`0 0 0 1 * *`)
-| `@weekly`                     | once a week (`0 0 0 * * 0`)
-| `@daily` (or `@midnight`)     | once a day (`0 0 0 * * *`), or
-| `@hourly`                     | once an hour, (`0 0 * * * *`)

-[[scheduling-quartz]]
-== Using the Quartz Scheduler
-
-Quartz uses `Trigger`, `Job`, and `JobDetail` objects to realize scheduling of all kinds
-of jobs. For the basic concepts behind Quartz, see
-https://www.quartz-scheduler.org/[]. For convenience purposes, Spring offers a couple of
-classes that simplify using Quartz within Spring-based applications.
-
-
-[[scheduling-quartz-jobdetail]]
-=== Using the `JobDetailFactoryBean`
-
-Quartz `JobDetail` objects contain all the information needed to run a job. Spring provides a
-`JobDetailFactoryBean`, which provides bean-style properties for XML configuration purposes.
-Consider the following example:
-
-[source,xml,indent=0,subs="verbatim,quotes"]
----
-	<bean name="exampleJob" class="org.springframework.scheduling.quartz.JobDetailFactoryBean">
-		<property name="jobClass" value="example.ExampleJob"/>
-		<property name="jobDataAsMap">
-			<map>
-				<entry key="timeout" value="5"/>
-			</map>
-		</property>
-	</bean>
----
-
-The job detail configuration has all the information it needs to run the job (`ExampleJob`).
-The timeout is specified in the job data map. The job data map is available through the
-`JobExecutionContext` (passed to you at execution time), but the `JobDetail` also gets
-its properties from the job data mapped to properties of the job instance. So, in the following example,
-the `ExampleJob` contains a bean property named `timeout`, and the `JobDetail`
-has it applied automatically:
-
-[source,java,indent=0]
-[subs="verbatim"]
----
-	package example;
-
-	public class ExampleJob extends QuartzJobBean {
-
-		private int timeout;
-
-		/**
-		 * Setter called after the ExampleJob is instantiated
-		 * with the value from the JobDetailFactoryBean (5)
-		 */
-		public void setTimeout(int timeout) {
-			this.timeout = timeout;
-		}
-
-		protected void executeInternal(JobExecutionContext ctx) throws JobExecutionException {
-			// do the actual work
-		}
-	}
----
-
-All additional properties from the job data map are available to you as well.
-
-NOTE: By using the `name` and `group` properties, you can modify the name and the group
-of the job, respectively. By default, the name of the job matches the bean name
-of the `JobDetailFactoryBean` (`exampleJob` in the preceding example above).
-
-
-[[scheduling-quartz-method-invoking-job]]
-=== Using the `MethodInvokingJobDetailFactoryBean`
-
-Often you merely need to invoke a method on a specific object. By using the
-`MethodInvokingJobDetailFactoryBean`, you can do exactly this, as the following example shows:
-
-[source,xml,indent=0,subs="verbatim,quotes"]
----
-	<bean id="jobDetail" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
-		<property name="targetObject" ref="exampleBusinessObject"/>
-		<property name="targetMethod" value="doIt"/>
-	</bean>
----
-
-The preceding example results in the `doIt` method being called on the
-`exampleBusinessObject` method, as the following example shows:
-
-[source,java,indent=0,subs="verbatim,quotes"]
----
-	public class ExampleBusinessObject {
-
-		// properties and collaborators
-
-		public void doIt() {
-			// do the actual work
-		}
-	}
----
-
-[source,xml,indent=0,subs="verbatim,quotes"]
----
-	<bean id="exampleBusinessObject" class="examples.ExampleBusinessObject"/>
----
-
-By using the `MethodInvokingJobDetailFactoryBean`, you need not create one-line jobs
-that merely invoke a method. You need only create the actual business object and
-wire up the detail object.
-
-By default, Quartz Jobs are stateless, resulting in the possibility of jobs interfering
-with each other. If you specify two triggers for the same `JobDetail`, it is
-possible that, before the first job has finished, the second one starts. If
-`JobDetail` classes implement the `Stateful` interface, this does not happen. The second
-job does not start before the first one has finished. To make jobs resulting from the
-`MethodInvokingJobDetailFactoryBean` be non-concurrent, set the `concurrent` flag to
-`false`, as the following example shows:
-
-[source,xml,indent=0,subs="verbatim,quotes"]
----
-	<bean id="jobDetail" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
-		<property name="targetObject" ref="exampleBusinessObject"/>
-		<property name="targetMethod" value="doIt"/>
-		<property name="concurrent" value="false"/>
-	</bean>
----
-
-NOTE: By default, jobs will run in a concurrent fashion.
-
-
-[[scheduling-quartz-cron]]
-=== Wiring up Jobs by Using Triggers and `SchedulerFactoryBean`
-
-We have created job details and jobs. We have also reviewed the convenience bean that lets
-you invoke a method on a specific object. Of course, we still need to schedule the
-jobs themselves. This is done by using triggers and a `SchedulerFactoryBean`. Several
-triggers are available within Quartz, and Spring offers two Quartz `FactoryBean`
-implementations with convenient defaults: `CronTriggerFactoryBean` and
-`SimpleTriggerFactoryBean`.
-
-Triggers need to be scheduled. Spring offers a `SchedulerFactoryBean` that exposes
-triggers to be set as properties. `SchedulerFactoryBean` schedules the actual jobs with
-those triggers.
-
-The following listing uses both a `SimpleTriggerFactoryBean` and a `CronTriggerFactoryBean`:
-
-[source,xml,indent=0]
-[subs="verbatim"]
----
-	<bean id="simpleTrigger" class="org.springframework.scheduling.quartz.SimpleTriggerFactoryBean">
-		<!-- see the example of method invoking job above -->
-		<property name="jobDetail" ref="jobDetail"/>
-		<!-- 10 seconds -->
-		<property name="startDelay" value="10000"/>
-		<!-- repeat every 50 seconds -->
-		<property name="repeatInterval" value="50000"/>
-	</bean>
-
-	<bean id="cronTrigger" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
-		<property name="jobDetail" ref="exampleJob"/>
-		<!-- run every morning at 6 AM -->
-		<property name="cronExpression" value="0 0 6 * * ?"/>
-	</bean>
----
-
-The preceding example sets up two triggers, one running every 50 seconds with a starting delay of 10
-seconds and one running every morning at 6 AM. To finalize everything, we need to set up the
-`SchedulerFactoryBean`, as the following example shows:
-
-[source,xml,indent=0,subs="verbatim,quotes"]
----
-	<bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
-		<property name="triggers">
-			<list>
-				<ref bean="cronTrigger"/>
-				<ref bean="simpleTrigger"/>
-			</list>
-		</property>
-	</bean>
----
-
-More properties are available for the `SchedulerFactoryBean`, such as the calendars used by the
-job details, properties to customize Quartz with, and a Spring-provided JDBC DataSource. See
-the {api-spring-framework}/scheduling/quartz/SchedulerFactoryBean.html[`SchedulerFactoryBean`]
-javadoc for more information.
-
-NOTE: `SchedulerFactoryBean` also recognizes a `quartz.properties` file in the classpath,
-based on Quartz property keys, as with regular Quartz configuration. Please note that many
-`SchedulerFactoryBean` settings interact with common Quartz settings in the properties file;
-it is therefore not recommended to specify values at both levels. For example, do not set
-an "org.quartz.jobStore.class" property if you mean to rely on a Spring-provided DataSource,
-or specify an `org.springframework.scheduling.quartz.LocalDataSourceJobStore` variant which
-is a full-fledged replacement for the standard `org.quartz.impl.jdbcjobstore.JobStoreTX`.

-= Dynamic Language Support
-
-Spring provides comprehensive support for using classes and objects that have been
-defined by using a dynamic language (such as Groovy) with Spring. This support lets
-you write any number of classes in a supported dynamic language and have the Spring
-container transparently instantiate, configure, and dependency inject the resulting
-objects.
-
-Spring's scripting support primarily targets Groovy and BeanShell. Beyond those
-specifically supported languages, the JSR-223 scripting mechanism is supported
-for integration with any JSR-223 capable language provider (as of Spring 4.2),
-e.g. JRuby.
-
-You can find fully working examples of where this dynamic language support can be
-immediately useful in <<dynamic-language-scenarios>>.
-
-
-
-
-[[dynamic-language-a-first-example]]
-== A First Example
-
-The bulk of this chapter is concerned with describing the dynamic language support in
-detail. Before diving into all of the ins and outs of the dynamic language support,
-we look at a quick example of a bean defined in a dynamic language. The dynamic
-language for this first bean is Groovy. (The basis of this example was taken from the
-Spring test suite. If you want to see equivalent examples in any of the other
-supported languages, take a look at the source code).
-
-The next example shows the `Messenger` interface, which the Groovy bean is going to
-implement. Note that this interface is defined in plain Java. Dependent objects that
-are injected with a reference to the `Messenger` do not know that the underlying
-implementation is a Groovy script. The following listing shows the `Messenger` interface:
-
-[source,java,indent=0,subs="verbatim,quotes"]
----
-	package org.springframework.scripting;
-
-	public interface Messenger {
-
-		String getMessage();
-	}
----
-
-The following example defines a class that has a dependency on the `Messenger` interface:
-
-[source,java,indent=0,subs="verbatim,quotes"]
----
-	package org.springframework.scripting;
-
-	public class DefaultBookingService implements BookingService {
-
-		private Messenger messenger;
-
-		public void setMessenger(Messenger messenger) {
-			this.messenger = messenger;
-		}
-
-		public void processBooking() {
-			// use the injected Messenger object...
-		}
-	}
----
-
-The following example implements the `Messenger` interface in Groovy:
-
-[source,groovy,indent=0,subs="verbatim,quotes"]
----
-	// from the file 'Messenger.groovy'
-	package org.springframework.scripting.groovy;
-
-	// import the Messenger interface (written in Java) that is to be implemented
-	import org.springframework.scripting.Messenger
-
-	// define the implementation in Groovy
-	class GroovyMessenger implements Messenger {
-
-		String message
-	}
----
-
-[NOTE]
-====
-To use the custom dynamic language tags to define dynamic-language-backed beans, you
-need to have the XML Schema preamble at the top of your Spring XML configuration file.
-You also need to use a Spring `ApplicationContext` implementation as your IoC
-container. Using the dynamic-language-backed beans with a plain `BeanFactory`
-implementation is supported, but you have to manage the plumbing of the Spring internals
-to do so.
-
-For more information on schema-based configuration, see <<xsd-schemas-lang,
-XML Schema-based Configuration>>.
-====
-
-Finally, the following example shows the bean definitions that effect the injection of the
-Groovy-defined `Messenger` implementation into an instance of the
-`DefaultBookingService` class:
-
-[source,xml,indent=0,subs="verbatim,quotes"]
----
-	<?xml version="1.0" encoding="UTF-8"?>
-	<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
-		xmlns:lang="http://www.springframework.org/schema/lang"
-		xsi:schemaLocation="
-			http://www.springframework.org/schema/beans https://www.springframework.org/schema/beans/spring-beans.xsd
-			http://www.springframework.org/schema/lang https://www.springframework.org/schema/lang/spring-lang.xsd">
-
-		<!-- this is the bean definition for the Groovy-backed Messenger implementation -->
-		<lang:groovy id="messenger" script-source="classpath:Messenger.groovy">
-			<lang:property name="message" value="I Can Do The Frug" />
-		</lang:groovy>
-
-		<!-- an otherwise normal bean that will be injected by the Groovy-backed Messenger -->
-		<bean id="bookingService" class="x.y.DefaultBookingService">
-			<property name="messenger" ref="messenger" />
-		</bean>
-
-	</beans>
----
-
-The `bookingService` bean (a `DefaultBookingService`) can now use its private `messenger`
-member variable as normal, because the `Messenger` instance that was injected into it is
-a `Messenger` instance. There is nothing special going on here -- just plain Java and
-plain Groovy.
-
-Hopefully, the preceding XML snippet is self-explanatory, but do not worry unduly if it is not.
-Keep reading for the in-depth detail on the whys and wherefores of the preceding configuration.

-[[dynamic-language-beans]]
-== Defining Beans that Are Backed by Dynamic Languages
-
-This section describes exactly how you define Spring-managed beans in any of the
-supported dynamic languages.
-
-Note that this chapter does not attempt to explain the syntax and idioms of the supported
-dynamic languages. For example, if you want to use Groovy to write certain of the classes
-in your application, we assume that you already know Groovy. If you need further details
-about the dynamic languages themselves, see <<dynamic-language-resources>> at the end of
-this chapter.
-
-
-
-[[dynamic-language-beans-concepts]]
-=== Common Concepts
-
-The steps involved in using dynamic-language-backed beans are as follows:
-
-. Write the test for the dynamic language source code (naturally).
-. Then write the dynamic language source code itself.
-. Define your dynamic-language-backed beans by using the appropriate `<lang:language/>`
-  element in the XML configuration (you can define such beans programmatically by
-  using the Spring API, although you will have to consult the source code for
-  directions on how to do this, as this chapter does not cover this type of advanced configuration).
-  Note that this is an iterative step. You need at least one bean definition for each dynamic
-  language source file (although multiple bean definitions can reference the same source file).
-
-The first two steps (testing and writing your dynamic language source files) are beyond
-the scope of this chapter. See the language specification and reference manual
-for your chosen dynamic language and crack on with developing your dynamic language
-source files. You first want to read the rest of this chapter, though, as
-Spring's dynamic language support does make some (small) assumptions about the contents
-of your dynamic language source files.
-
-
-[[dynamic-language-beans-concepts-xml-language-element]]
-==== The <lang:language/> element
-
-The final step in the list in the <<dynamic-language-beans-concepts, preceding section>>
-involves defining dynamic-language-backed bean definitions, one for each bean that you
-want to configure (this is no different from normal JavaBean configuration). However,
-instead of specifying the fully qualified class name of the class that is to be
-instantiated and configured by the container, you can use the `<lang:language/>`
-element to define the dynamic language-backed bean.
-
-Each of the supported languages has a corresponding `<lang:language/>` element:
-
-* `<lang:groovy/>` (Groovy)
-* `<lang:bsh/>` (BeanShell)
-* `<lang:std/>` (JSR-223, e.g. with JRuby)
-
-The exact attributes and child elements that are available for configuration depends on
-exactly which language the bean has been defined in (the language-specific sections
-later in this chapter detail this).
-
-
-[[dynamic-language-refreshable-beans]]
-==== Refreshable Beans
-
-One of the (and perhaps the single) most compelling value adds of the dynamic language
-support in Spring is the "`refreshable bean`" feature.
-
-A refreshable bean is a dynamic-language-backed bean. With a small amount of
-configuration, a dynamic-language-backed bean can monitor changes in its underlying
-source file resource and then reload itself when the dynamic language source file is
-changed (for example, when you edit and save changes to the file on the file system).
-
-This lets you deploy any number of dynamic language source files as part of an
-application, configure the Spring container to create beans backed by dynamic
-language source files (using the mechanisms described in this chapter), and (later,
-as requirements change or some other external factor comes into play) edit a dynamic
-language source file and have any change they make be reflected in the bean that is
-backed by the changed dynamic language source file. There is no need to shut down a
-running application (or redeploy in the case of a web application). The
-dynamic-language-backed bean so amended picks up the new state and logic from the
-changed dynamic language source file.
-
-NOTE: This feature is off by default.
-
-Now we can take a look at an example to see how easy it is to start using refreshable
-beans. To turn on the refreshable beans feature, you have to specify exactly one
-additional attribute on the `<lang:language/>` element of your bean definition. So,
-if we stick with <<dynamic-language-a-first-example, the example>> from earlier in
-this chapter, the following example shows what we would change in the Spring XML
-configuration to effect refreshable beans:
-
-[source,xml,indent=0,subs="verbatim,quotes"]
----
-	<beans>
-
-		<!-- this bean is now 'refreshable' due to the presence of the 'refresh-check-delay' attribute -->
-		<lang:groovy id="messenger"
-				refresh-check-delay="5000" <!-- switches refreshing on with 5 seconds between checks -->
-				script-source="classpath:Messenger.groovy">
-			<lang:property name="message" value="I Can Do The Frug" />
-		</lang:groovy>
-
-		<bean id="bookingService" class="x.y.DefaultBookingService">
-			<property name="messenger" ref="messenger" />
-		</bean>
-
-	</beans>
----
-
-That really is all you have to do. The `refresh-check-delay` attribute defined on the
-`messenger` bean definition is the number of milliseconds after which the bean is
-refreshed with any changes made to the underlying dynamic language source file.
-You can turn off the refresh behavior by assigning a negative value to the
-`refresh-check-delay` attribute. Remember that, by default, the refresh behavior is
-disabled. If you do not want the refresh behavior, do not define the attribute.
-
-If we then run the following application, we can exercise the refreshable feature.
-(Please excuse the "`jumping-through-hoops-to-pause-the-execution`" shenanigans
-in this next slice of code.) The `System.in.read()` call is only there so that the
-execution of the program pauses while you (the developer in this scenario) go off
-and edit the underlying dynamic language source file so that the refresh triggers
-on the dynamic-language-backed bean when the program resumes execution.
-
-The following listing shows this sample application:
-
-[source,java,indent=0,subs="verbatim,quotes"]
----
-	import org.springframework.context.ApplicationContext;
-	import org.springframework.context.support.ClassPathXmlApplicationContext;
-	import org.springframework.scripting.Messenger;
-
-	public final class Boot {
-
-		public static void main(final String[] args) throws Exception {
-			ApplicationContext ctx = new ClassPathXmlApplicationContext("beans.xml");
-			Messenger messenger = (Messenger) ctx.getBean("messenger");
-			System.out.println(messenger.getMessage());
-			// pause execution while I go off and make changes to the source file...
-			System.in.read();
-			System.out.println(messenger.getMessage());
-		}
-	}
----
-
-Assume then, for the purposes of this example, that all calls to the `getMessage()`
-method of `Messenger` implementations have to be changed such that the message is
-surrounded by quotation marks. The following listing shows the changes that you
-(the developer) should make to the `Messenger.groovy` source file when the
-execution of the program is paused:
-
-[source,groovy,indent=0,subs="verbatim,quotes"]
----
-	package org.springframework.scripting
-
-	class GroovyMessenger implements Messenger {
-
-		private String message = "Bingo"
-
-		public String getMessage() {
-			// change the implementation to surround the message in quotes
-			return "'" + this.message + "'"
-		}
-
-		public void setMessage(String message) {
-			this.message = message
-		}
-	}
----
-
-When the program runs, the output before the input pause will be `I Can Do The Frug`.
-After the change to the source file is made and saved and the program resumes execution,
-the result of calling the `getMessage()` method on the dynamic-language-backed
-`Messenger` implementation is `'I Can Do The Frug'` (notice the inclusion of the
-additional quotation marks).
-
-Changes to a script do not trigger a refresh if the changes occur within the window of
-the `refresh-check-delay` value. Changes to the script are not actually picked up until
-a method is called on the dynamic-language-backed bean. It is only when a method is
-called on a dynamic-language-backed bean that it checks to see if its underlying script
-source has changed. Any exceptions that relate to refreshing the script (such as
-encountering a compilation error or finding that the script file has been deleted)
-results in a fatal exception being propagated to the calling code.
-
-The refreshable bean behavior described earlier does not apply to dynamic language
-source files defined with the `<lang:inline-script/>` element notation (see
-<<dynamic-language-beans-inline>>). Additionally, it applies only to beans where
-changes to the underlying source file can actually be detected (for example, by code
-that checks the last modified date of a dynamic language source file that exists on the
-file system).
-
-
-[[dynamic-language-beans-inline]]
-==== Inline Dynamic Language Source Files
-
-The dynamic language support can also cater to dynamic language source files that are
-embedded directly in Spring bean definitions. More specifically, the
-`<lang:inline-script/>` element lets you define dynamic language source immediately
-inside a Spring configuration file. An example might clarify how the inline script
-feature works:
-
-[source,xml,indent=0,subs="verbatim,quotes"]
----
-	<lang:groovy id="messenger">
-		<lang:inline-script>
-
-	package org.springframework.scripting.groovy;
-
-	import org.springframework.scripting.Messenger
-
-	class GroovyMessenger implements Messenger {
-		String message
-	}
-
-		</lang:inline-script>
-		<lang:property name="message" value="I Can Do The Frug" />
-	</lang:groovy>
----
-
-If we put to one side the issues surrounding whether it is good practice to define
-dynamic language source inside a Spring configuration file, the `<lang:inline-script/>`
-element can be useful in some scenarios. For instance, we might want to quickly add a
-Spring `Validator` implementation to a Spring MVC `Controller`. This is but a moment's
-work using inline source. (See <<dynamic-language-scenarios-validators>> for such an
-example.)
-
-
-[[dynamic-language-beans-ctor-injection]]
-==== Understanding Constructor Injection in the Context of Dynamic-language-backed Beans
-
-There is one very important thing to be aware of with regard to Spring's dynamic
-language support. Namely, you can not (currently) supply constructor arguments
-to dynamic-language-backed beans (and, hence, constructor-injection is not available for
-dynamic-language-backed beans). In the interests of making this special handling of
-constructors and properties 100% clear, the following mixture of code and configuration
-does not work:
-
-.An approach that cannot work
-[source,groovy,indent=0,subs="verbatim,quotes"]
----
-	// from the file 'Messenger.groovy'
-	package org.springframework.scripting.groovy;
-
-	import org.springframework.scripting.Messenger
-
-	class GroovyMessenger implements Messenger {
-
-		GroovyMessenger() {}
-
-		// this constructor is not available for Constructor Injection
-		GroovyMessenger(String message) {
-			this.message = message;
-		}
-
-		String message
-
-		String anotherMessage
-	}
----
-
-[source,xml,indent=0,subs="verbatim,quotes"]
----
-	<lang:groovy id="badMessenger"
-		script-source="classpath:Messenger.groovy">
-		<!-- this next constructor argument will not be injected into the GroovyMessenger -->
-		<!-- in fact, this isn't even allowed according to the schema -->
-		<constructor-arg value="This will not work" />
-
-		<!-- only property values are injected into the dynamic-language-backed object -->
-		<lang:property name="anotherMessage" value="Passed straight through to the dynamic-language-backed object" />
-
-	</lang>
----
-
-In practice this limitation is not as significant as it first appears, since setter
-injection is the injection style favored by the overwhelming majority of developers
-(we leave the discussion as to whether that is a good thing to another day).

-
-[[dynamic-language-beans-groovy]]
-=== Groovy Beans
-
-This section describes how to use beans defined in Groovy in Spring.
-
-The Groovy homepage includes the following description:
-
-"`Groovy is an agile dynamic language for the Java 2 Platform that has many of the
-features that people like so much in languages like Python, Ruby and Smalltalk, making
-them available to Java developers using a Java-like syntax.`"
-
-If you have read this chapter straight from the top, you have already
-<<dynamic-language-a-first-example, seen an example>> of a Groovy-dynamic-language-backed
-bean. Now consider another example (again using an example from the Spring test suite):
-
-[source,java,indent=0,subs="verbatim,quotes"]
----
-	package org.springframework.scripting;
-
-	public interface Calculator {
-
-		int add(int x, int y);
-	}
----
-
-The following example implements the `Calculator` interface in Groovy:
-
-[source,groovy,indent=0,subs="verbatim,quotes"]
----
-	// from the file 'calculator.groovy'
-	package org.springframework.scripting.groovy
-
-	class GroovyCalculator implements Calculator {
-
-		int add(int x, int y) {
-			x + y
-		}
-	}
----
-
-The following bean definition uses the calculator defined in Groovy:
-
-[source,xml,indent=0,subs="verbatim,quotes"]
----
-	<!-- from the file 'beans.xml' -->
-	<beans>
-		<lang:groovy id="calculator" script-source="classpath:calculator.groovy"/>
-	</beans>
----
-
-Finally, the following small application exercises the preceding configuration:
-
-[source,java,indent=0,subs="verbatim,quotes"]
----
-	package org.springframework.scripting;
-
-	import org.springframework.context.ApplicationContext;
-	import org.springframework.context.support.ClassPathXmlApplicationContext;
-
-	public class Main {
-
-		public static void main(String[] args) {
-			ApplicationContext ctx = new ClassPathXmlApplicationContext("beans.xml");
-			Calculator calc = ctx.getBean("calculator", Calculator.class);
-			System.out.println(calc.add(2, 8));
-		}
-	}
----
-
-The resulting output from running the above program is (unsurprisingly) `10`.
-(For more interesting examples, see the dynamic language showcase project for a more
-complex example or see the examples <<dynamic-language-scenarios>> later in this chapter).
-
-You must not define more than one class per Groovy source file. While this is perfectly
-legal in Groovy, it is (arguably) a bad practice. In the interests of a consistent
-approach, you should (in the opinion of the Spring team) respect the standard Java
-conventions of one (public) class per source file.
-
-
-[[dynamic-language-beans-groovy-customizer]]
-==== Customizing Groovy Objects by Using a Callback
-
-The `GroovyObjectCustomizer` interface is a callback that lets you hook additional
-creation logic into the process of creating a Groovy-backed bean. For example,
-implementations of this interface could invoke any required initialization methods,
-set some default property values, or specify a custom `MetaClass`. The following listing
-shows the `GroovyObjectCustomizer` interface definition:
-
-[source,java,indent=0,subs="verbatim,quotes"]
----
-	public interface GroovyObjectCustomizer {
-
-		void customize(GroovyObject goo);
-	}
----
-
-The Spring Framework instantiates an instance of your Groovy-backed bean and then
-passes the created `GroovyObject` to the specified `GroovyObjectCustomizer` (if one
-has been defined). You can do whatever you like with the supplied `GroovyObject`
-reference. We expect that most people want to set a custom `MetaClass` with this
-callback, and the following example shows how to do so:
-
-[source,java,indent=0,subs="verbatim,quotes"]
----
-	public final class SimpleMethodTracingCustomizer implements GroovyObjectCustomizer {
-
-		public void customize(GroovyObject goo) {
-			DelegatingMetaClass metaClass = new DelegatingMetaClass(goo.getMetaClass()) {
-
-				public Object invokeMethod(Object object, String methodName, Object[] arguments) {
-					System.out.println("Invoking '" + methodName + "'.");
-					return super.invokeMethod(object, methodName, arguments);
-				}
-			};
-			metaClass.initialize();
-			goo.setMetaClass(metaClass);
-		}
-
-	}
----
-
-A full discussion of meta-programming in Groovy is beyond the scope of the Spring
-reference manual. See the relevant section of the Groovy reference manual or do a
-search online. Plenty of articles address this topic. Actually, making use of a
-`GroovyObjectCustomizer` is easy if you use the Spring namespace support, as the
-following example shows:
-
-[source,xml,indent=0,subs="verbatim,quotes"]
----
-	<!-- define the GroovyObjectCustomizer just like any other bean -->
-	<bean id="tracingCustomizer" class="example.SimpleMethodTracingCustomizer"/>
-
-		<!-- ... and plug it into the desired Groovy bean via the 'customizer-ref' attribute -->
-		<lang:groovy id="calculator"
-			script-source="classpath:org/springframework/scripting/groovy/Calculator.groovy"
-			customizer-ref="tracingCustomizer"/>
----
-
-If you do not use the Spring namespace support, you can still use the
-`GroovyObjectCustomizer` functionality, as the following example shows:
-
-[source,xml,indent=0,subs="verbatim,quotes"]
----
-	<bean id="calculator" class="org.springframework.scripting.groovy.GroovyScriptFactory">
-		<constructor-arg value="classpath:org/springframework/scripting/groovy/Calculator.groovy"/>
-		<!-- define the GroovyObjectCustomizer (as an inner bean) -->
-		<constructor-arg>
-			<bean id="tracingCustomizer" class="example.SimpleMethodTracingCustomizer"/>
-		</constructor-arg>
-	</bean>
-
-	<bean class="org.springframework.scripting.support.ScriptFactoryPostProcessor"/>
----
-
-NOTE: You may also specify a Groovy `CompilationCustomizer` (such as an `ImportCustomizer`)
-or even a full Groovy `CompilerConfiguration` object in the same place as Spring's
-`GroovyObjectCustomizer`. Furthermore, you may set a common `GroovyClassLoader` with custom
-configuration for your beans at the `ConfigurableApplicationContext.setClassLoader` level;
-this also leads to shared `GroovyClassLoader` usage and is therefore recommendable in case of
-a large number of scripted beans (avoiding an isolated `GroovyClassLoader` instance per bean).
-
-
-
-[[dynamic-language-beans-bsh]]
-=== BeanShell Beans
-
-This section describes how to use BeanShell beans in Spring.
-
-The https://beanshell.github.io/intro.html[BeanShell homepage] includes the following
-description:
-
----
-BeanShell is a small, free, embeddable Java source interpreter with dynamic language
-features, written in Java. BeanShell dynamically runs standard Java syntax and
-extends it with common scripting conveniences such as loose types, commands, and method
-closures like those in Perl and JavaScript.
----
-
-In contrast to Groovy, BeanShell-backed bean definitions require some (small) additional
-configuration. The implementation of the BeanShell dynamic language support in Spring is
-interesting, because Spring creates a JDK dynamic proxy that implements all of the
-interfaces that are specified in the `script-interfaces` attribute value of the
-`<lang:bsh>` element (this is why you must supply at least one interface in the value
-of the attribute, and, consequently, program to interfaces when you use BeanShell-backed
-beans). This means that every method call on a BeanShell-backed object goes through the
-JDK dynamic proxy invocation mechanism.
-
-Now we can show a fully working example of using a BeanShell-based bean that implements
-the `Messenger` interface that was defined earlier in this chapter. We again show the
-definition of the `Messenger` interface:
-
-[source,java,indent=0,subs="verbatim,quotes"]
----
-	package org.springframework.scripting;
-
-	public interface Messenger {
-
-		String getMessage();
-	}
----
-
-The following example shows the BeanShell "`implementation`" (we use the term loosely here)
-of the `Messenger` interface:
-
-[source,java,indent=0,subs="verbatim,quotes"]
----
-	String message;
-
-	String getMessage() {
-		return message;
-	}
-
-	void setMessage(String aMessage) {
-		message = aMessage;
-	}
----
-
-The following example shows the Spring XML that defines an "`instance`" of the above
-"`class`" (again, we use these terms very loosely here):
-
-[source,xml,indent=0,subs="verbatim,quotes"]
----
-	<lang:bsh id="messageService" script-source="classpath:BshMessenger.bsh"
-		script-interfaces="org.springframework.scripting.Messenger">
-
-		<lang:property name="message" value="Hello World!" />
-	</lang:bsh>
----
-
-See <<dynamic-language-scenarios>> for some scenarios where you might want to use
-BeanShell-based beans.
-
-
-
-
-[[dynamic-language-scenarios]]
-== Scenarios
-
-The possible scenarios where defining Spring managed beans in a scripting language would
-be beneficial are many and varied. This section describes two possible use cases for the
-dynamic language support in Spring.
-
-
-
-[[dynamic-language-scenarios-controllers]]
-=== Scripted Spring MVC Controllers
-
-One group of classes that can benefit from using dynamic-language-backed beans is that
-of Spring MVC controllers. In pure Spring MVC applications, the navigational flow
-through a web application is, to a large extent, determined by code encapsulated within
-your Spring MVC controllers. As the navigational flow and other presentation layer logic
-of a web application needs to be updated to respond to support issues or changing
-business requirements, it may well be easier to effect any such required changes by
-editing one or more dynamic language source files and seeing those changes being
-immediately reflected in the state of a running application.
-
-Remember that, in the lightweight architectural model espoused by projects such as
-Spring, you typically aim to have a really thin presentation layer, with all
-the meaty business logic of an application being contained in the domain and service
-layer classes. Developing Spring MVC controllers as dynamic-language-backed beans lets
-you change presentation layer logic by editing and saving text files. Any
-changes to such dynamic language source files is (depending on the configuration)
-automatically reflected in the beans that are backed by dynamic language source files.
-
-NOTE: To effect this automatic "`pickup`" of any changes to dynamic-language-backed
-beans, you have to enable the "`refreshable beans`" functionality. See
-<<dynamic-language-refreshable-beans>> for a full treatment of this feature.
-
-The following example shows an `org.springframework.web.servlet.mvc.Controller` implemented
-by using the Groovy dynamic language:
-
-[source,groovy,indent=0,subs="verbatim,quotes"]
----
-	// from the file '/WEB-INF/groovy/FortuneController.groovy'
-	package org.springframework.showcase.fortune.web
-
-	import org.springframework.showcase.fortune.service.FortuneService
-	import org.springframework.showcase.fortune.domain.Fortune
-	import org.springframework.web.servlet.ModelAndView
-	import org.springframework.web.servlet.mvc.Controller
-
-	import jakarta.servlet.http.HttpServletRequest
-	import jakarta.servlet.http.HttpServletResponse
-
-	class FortuneController implements Controller {
-
-		@Property FortuneService fortuneService
-
-		ModelAndView handleRequest(HttpServletRequest request,
-				HttpServletResponse httpServletResponse) {
-			return new ModelAndView("tell", "fortune", this.fortuneService.tellFortune())
-		}
-	}
----
-
-[source,xml,indent=0,subs="verbatim,quotes"]
----
-	<lang:groovy id="fortune"
-			refresh-check-delay="3000"
-			script-source="/WEB-INF/groovy/FortuneController.groovy">
-		<lang:property name="fortuneService" ref="fortuneService"/>
-	</lang:groovy>
----
-
-
-
-[[dynamic-language-scenarios-validators]]
-=== Scripted Validators
-
-Another area of application development with Spring that may benefit from the
-flexibility afforded by dynamic-language-backed beans is that of validation. It can
-be easier to express complex validation logic by using a loosely typed dynamic language
-(that may also have support for inline regular expressions) as opposed to regular Java.
-
-Again, developing validators as dynamic-language-backed beans lets you change
-validation logic by editing and saving a simple text file. Any such changes is
-(depending on the configuration) automatically reflected in the execution of a
-running application and would not require the restart of an application.
-
-NOTE: To effect the automatic "`pickup`" of any changes to dynamic-language-backed
-beans, you have to enable the 'refreshable beans' feature. See
-<<dynamic-language-refreshable-beans>> for a full and detailed treatment of this feature.
-
-The following example shows a Spring `org.springframework.validation.Validator`
-implemented by using the Groovy dynamic language (see <<core.adoc#validator,
-Validation using Spring’s Validator interface>> for a discussion of the
-`Validator` interface):
-
-[source,groovy,indent=0,subs="verbatim,quotes"]
----
-	import org.springframework.validation.Validator
-	import org.springframework.validation.Errors
-	import org.springframework.beans.TestBean
-
-	class TestBeanValidator implements Validator {
-
-		boolean supports(Class clazz) {
-			return TestBean.class.isAssignableFrom(clazz)
-		}
-
-		void validate(Object bean, Errors errors) {
-			if(bean.name?.trim()?.size() > 0) {
-				return
-			}
-			errors.reject("whitespace", "Cannot be composed wholly of whitespace.")
-		}
-	}
----
-
-
-
-
-[[dynamic-language-final-notes]]
-== Additional Details
-
-This last section contains some additional details related to the dynamic language support.
-
-
-
-[[dynamic-language-final-notes-aop]]
-=== AOP -- Advising Scripted Beans
-
-You can use the Spring AOP framework to advise scripted beans. The Spring AOP
-framework actually is unaware that a bean that is being advised might be a scripted
-bean, so all of the AOP use cases and functionality that you use (or aim to use)
-work with scripted beans. When you advise scripted beans, you cannot use class-based
-proxies. You must use <<core.adoc#aop-proxying, interface-based proxies>>.
-
-You are not limited to advising scripted beans. You can also write aspects themselves
-in a supported dynamic language and use such beans to advise other Spring beans.
-This really would be an advanced use of the dynamic language support though.
-
-
-
-[[dynamic-language-final-notes-scopes]]
-=== Scoping
-
-In case it is not immediately obvious, scripted beans can be scoped in the same way as
-any other bean. The `scope` attribute on the various `<lang:language/>` elements lets
-you control the scope of the underlying scripted bean, as it does with a regular
-bean. (The default scope is <<core.adoc#beans-factory-scopes-singleton, singleton>>,
-as it is with "`regular`" beans.)
-
-The following example uses the `scope` attribute to define a Groovy bean scoped as
-a <<core.adoc#beans-factory-scopes-prototype, prototype>>:
-
-[source,xml,indent=0,subs="verbatim,quotes"]
----
-	<?xml version="1.0" encoding="UTF-8"?>
-	<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

-		</lang:groovy>
-
-		<bean id="bookingService" class="x.y.DefaultBookingService">
-			<property name="messenger" ref="messenger" />
-		</bean>
-
-	</beans>
----
-
-See <<core.adoc#beans-factory-scopes, Bean Scopes>> in <<core.adoc#beans, The IoC Container>>
-for a full discussion of the scoping support in the Spring Framework.
-
-
-
-[[xsd-schemas-lang]]
-=== The `lang` XML schema
-
-The `lang` elements in Spring XML configuration deal with exposing objects that have been
-written in a dynamic language (such as Groovy or BeanShell) as beans in the Spring container.
-
-These elements (and the dynamic language support) are comprehensively covered in
-<<dynamic-language, Dynamic Language Support>>. See that section
-for full details on this support and the `lang` elements.
-
-To use the elements in the `lang` schema, you need to have the following preamble at the
-top of your Spring XML configuration file. The text in the following snippet references
-the correct schema so that the tags in the `lang` namespace are available to you:

-Spring makes it easy to create Java enterprise applications. It provides everything you
-need to embrace the Java language in an enterprise environment, with support for Groovy
-and Kotlin as alternative languages on the JVM, and with the flexibility to create many
-kinds of architectures depending on an application's needs. As of Spring Framework 6.0,
-Spring requires Java 17+.
-
-Spring supports a wide range of application scenarios. In a large enterprise, applications
-often exist for a long time and have to run on a JDK and application server whose upgrade
-cycle is beyond developer control. Others may run as a single jar with the server embedded,
-possibly in a cloud environment. Yet others may be standalone applications (such as batch
-or integration workloads) that do not need a server.

-projects have been built on top of the Spring Framework. Most often, when people say
-"Spring", they mean the entire family of projects. This reference documentation focuses on
-the foundation: the Spring Framework itself.
-
-The Spring Framework is divided into modules. Applications can choose which modules they need.
-At the heart are the modules of the core container, including a configuration model and a
-dependency injection mechanism. Beyond that, the Spring Framework provides foundational
-support for different application architectures, including messaging, transactional data and
-persistence, and web. It also includes the Servlet-based Spring MVC web framework and, in
-parallel, the Spring WebFlux reactive web framework.
-
-A note about modules: Spring's framework jars allow for deployment to JDK 9's module path
-("Jigsaw"). For use in Jigsaw-enabled applications, the Spring Framework 5 jars come with
-"Automatic-Module-Name" manifest entries which define stable language-level module names
-("spring.core", "spring.context", etc.) independent from jar artifact names (the jars follow
-the same naming pattern with "-" instead of ".", e.g. "spring-core" and "spring-context").
-Of course, Spring's framework jars keep working fine on the classpath on both JDK 8 and 9+.

-[[overview-history]]
-== History of Spring and the Spring Framework
-
-Spring came into being in 2003 as a response to the complexity of the early
-https://en.wikipedia.org/wiki/Java_Platform,_Enterprise_Edition[J2EE] specifications.
-While some consider Java EE and its modern-day successor Jakarta EE to be in
-competition with Spring, they are in fact complementary. The Spring programming
-model does not embrace the Jakarta EE platform specification; rather, it integrates
-with carefully selected individual specifications from the traditional EE umbrella:
-
-* Servlet API (https://jcp.org/en/jsr/detail?id=340[JSR 340])
-* WebSocket API (https://www.jcp.org/en/jsr/detail?id=356[JSR 356])
-* Concurrency Utilities (https://www.jcp.org/en/jsr/detail?id=236[JSR 236])
-* JSON Binding API (https://jcp.org/en/jsr/detail?id=367[JSR 367])
-* Bean Validation (https://jcp.org/en/jsr/detail?id=303[JSR 303])
-* JPA (https://jcp.org/en/jsr/detail?id=338[JSR 338])
-* JMS (https://jcp.org/en/jsr/detail?id=914[JSR 914])
-* as well as JTA/JCA setups for transaction coordination, if necessary.
-
-The Spring Framework also supports the Dependency Injection
-(https://www.jcp.org/en/jsr/detail?id=330[JSR 330]) and Common Annotations
-(https://jcp.org/en/jsr/detail?id=250[JSR 250]) specifications, which application
-developers may choose to use instead of the Spring-specific mechanisms provided
-by the Spring Framework. Originally, those were based on common `javax` packages.
-
-As of Spring Framework 6.0, Spring has been upgraded to the Jakarta EE 9 level
-(e.g. Servlet 5.0+, JPA 3.0+), based on the `jakarta` namespace instead of the
-traditional `javax` packages. With EE 9 as the minimum and EE 10 supported already,
-Spring is prepared to provide out-of-the-box support for the further evolution of
-the Jakarta EE APIs. Spring Framework 6.0 is fully compatible with Tomcat 10.1,
-Jetty 11 and Undertow 2.3 as web servers, and also with Hibernate ORM 6.1.
-
-Over time, the role of Java/Jakarta EE in application development has evolved. In the
-early days of J2EE and Spring, applications were created to be deployed to an application
-server. Today, with the help of Spring Boot, applications are created in a devops- and
-cloud-friendly way, with the Servlet container embedded and trivial to change. As of
-Spring Framework 5, a WebFlux application does not even use the Servlet API directly
-and can run on servers (such as Netty) that are not Servlet containers.
-
-Spring continues to innovate and to evolve. Beyond the Spring Framework, there are other
-projects, such as Spring Boot, Spring Security, Spring Data, Spring Cloud, Spring Batch,
-among others. It’s important to remember that each project has its own source code repository,
-issue tracker, and release cadence. See https://spring.io/projects[spring.io/projects] for
-the complete list of Spring projects.
-
-
-
-
-[[overview-philosophy]]
-== Design Philosophy
-
-When you learn about a framework, it’s important to know not only what it does but what
-principles it follows. Here are the guiding principles of the Spring Framework:
-
-* Provide choice at every level. Spring lets you defer design decisions as late as possible.
-For example, you can switch persistence providers through configuration without changing
-your code. The same is true for many other infrastructure concerns and integration with
-third-party APIs.
-* Accommodate diverse perspectives. Spring embraces flexibility and is not opinionated
-about how things should be done. It supports a wide range of application needs with
-different perspectives.
-* Maintain strong backward compatibility. Spring’s evolution has been carefully managed
-to force few breaking changes between versions. Spring supports a carefully chosen range
-of JDK versions and third-party libraries to facilitate maintenance of applications and
-libraries that depend on Spring.
-* Care about API design. The Spring team puts a lot of thought and time into making APIs
-that are intuitive and that hold up across many versions and many years.
-* Set high standards for code quality. The Spring Framework puts a strong emphasis on
-meaningful, current, and accurate javadoc. It is one of very few projects that can claim
-clean code structure with  no circular dependencies between packages.

-== Getting Started
-
-If you are just getting started with Spring, you may want to begin using the Spring
-Framework by creating a https://projects.spring.io/spring-boot/[Spring Boot]-based
-application. Spring Boot provides a quick (and opinionated) way to create a
-production-ready Spring-based application. It is based on the Spring Framework, favors
-convention over configuration, and is designed to get you up and running as quickly
-as possible.
-
-You can use https://start.spring.io/[start.spring.io] to generate a basic project or follow
-one of the https://spring.io/guides["Getting Started" guides], such as
-https://spring.io/guides/gs/rest-service/[Getting Started Building a RESTful Web Service].
-As well as being easier to digest, these guides are very task focused, and most of them
-are based on Spring Boot. They also cover other projects from the Spring portfolio that
-you might want to consider when solving a particular problem.

-
-This section describes Spring Framework's support for the RSocket protocol.
-
-
-[[rsocket-overview]]
-== Overview
-
-RSocket is an application protocol for multiplexed, duplex communication over TCP,
-WebSocket, and other byte stream transports, using one of the following interaction
-models:
-
-* `Request-Response` -- send one message and receive one back.
-* `Request-Stream` -- send one message and receive a stream of messages back.
-* `Channel` -- send streams of messages in both directions.
-* `Fire-and-Forget` -- send a one-way message.
-
-Once the initial connection is made, the "client" vs "server" distinction is lost as
-both sides become symmetrical and each side can initiate one of the above interactions.
-This is why in the protocol calls the participating sides "requester" and "responder"
-while the above interactions are called "request streams" or simply "requests".
-
-These are the key features and benefits of the RSocket protocol:
-
-* https://www.reactive-streams.org/[Reactive Streams] semantics across network boundary --
-for streaming requests such as `Request-Stream` and `Channel`, back pressure signals
-travel between requester and responder, allowing a requester to slow down a responder at
-the source, hence reducing reliance on network layer congestion control, and the need
-for buffering at the network level or at any level.
-* Request throttling -- this feature is named "Leasing" after the `LEASE` frame that
-can be sent from each end to limit the total number of requests allowed by other end
-for a given time. Leases are renewed periodically.
-* Session resumption -- this is designed for loss of connectivity and requires some state
-to be maintained. The state management is transparent for applications, and works well
-in combination with back pressure which can stop a producer when possible and reduce
-the amount of state required.
-* Fragmentation and re-assembly of large messages.
-* Keepalive (heartbeats).
-
-RSocket has {gh-rsocket}[implementations] in multiple languages. The
-{gh-rsocket-java}[Java library] is built on https://projectreactor.io/[Project Reactor],
-and https://github.com/reactor/reactor-netty[Reactor Netty] for the transport. That means
-signals from Reactive Streams Publishers in your application propagate transparently
-through RSocket across the network.
-
-
-
-[[rsocket-protocol]]
-=== The Protocol
-
-One of the benefits of RSocket is that it has well defined behavior on the wire and an
-easy to read https://rsocket.io/about/protocol[specification] along with some protocol
-{gh-rsocket}/rsocket/tree/master/Extensions[extensions]. Therefore it is
-a good idea to read the spec, independent of language implementations and higher level
-framework APIs. This section provides a succinct overview to establish some context.
-
-**Connecting**
-
-Initially a client connects to a server via some low level streaming transport such
-as TCP or WebSocket and sends a `SETUP` frame to the server to set parameters for the
-connection.
-
-The server may reject the `SETUP` frame, but generally after it is sent (for the client)
-and received (for the server), both sides can begin to make requests, unless `SETUP`
-indicates use of leasing semantics to limit the number of requests, in which case
-both sides must wait for a `LEASE` frame from the other end to permit making requests.
-
-**Making Requests**
-
-Once a connection is established, both sides may initiate a request through one of the
-frames `REQUEST_RESPONSE`, `REQUEST_STREAM`, `REQUEST_CHANNEL`, or `REQUEST_FNF`. Each of
-those frames carries one message from the requester to the responder.
-
-The responder may then return `PAYLOAD` frames with response messages, and in the case
-of `REQUEST_CHANNEL` the requester may also send `PAYLOAD` frames with more request
-messages.
-
-When a request involves a stream of messages such as `Request-Stream` and `Channel`,
-the responder must respect demand signals from the requester. Demand is expressed as a
-number of messages. Initial demand is specified in `REQUEST_STREAM` and
-`REQUEST_CHANNEL` frames. Subsequent demand is signaled via `REQUEST_N` frames.
-
-Each side may also send metadata notifications, via the `METADATA_PUSH` frame, that do not
-pertain to any individual request but rather to the connection as a whole.
-
-**Message Format**
-
-RSocket messages contain data and metadata. Metadata can be used to send a route, a
-security token, etc. Data and metadata can be formatted differently. Mime types for each
-are declared in the `SETUP` frame and apply to all requests on a given connection.
-
-While all messages can have metadata, typically metadata such as a route are per-request
-and therefore only included in the first message on a request, i.e. with one of the frames
-`REQUEST_RESPONSE`, `REQUEST_STREAM`, `REQUEST_CHANNEL`, or `REQUEST_FNF`.
-
-Protocol extensions define common metadata formats for use in applications:
-
-* {gh-rsocket-extensions}/CompositeMetadata.md[Composite Metadata]-- multiple,
-  independently formatted metadata entries.
-* {gh-rsocket-extensions}/Routing.md[Routing] -- the route for a request.
-
-
-
-[[rsocket-java]]
-=== Java Implementation
-
-The {gh-rsocket-java}[Java implementation] for RSocket is built on
-https://projectreactor.io/[Project Reactor]. The transports for  TCP and WebSocket are
-built on https://github.com/reactor/reactor-netty[Reactor Netty]. As a Reactive Streams
-library, Reactor simplifies the job of implementing the protocol. For applications it is
-a natural fit to use `Flux` and `Mono` with declarative operators and transparent back
-pressure support.
-
-The API in RSocket Java is intentionally minimal and basic. It focuses on protocol
-features and leaves the application programming model (e.g. RPC codegen vs other) as a
-higher level, independent concern.
-
-The main contract
-{gh-rsocket-java}/blob/master/rsocket-core/src/main/java/io/rsocket/RSocket.java[io.rsocket.RSocket]
-models the four request interaction types with `Mono` representing a promise for a
-single message, `Flux` a stream of messages, and `io.rsocket.Payload` the actual
-message with access to data and metadata as byte buffers. The `RSocket` contract is used
-symmetrically. For requesting, the application is given an `RSocket` to perform
-requests with. For responding, the application implements `RSocket` to handle requests.
-
-This is not meant to be a thorough introduction. For the most part, Spring applications
-will not have to use its API directly. However it may be important to see or experiment
-with RSocket independent of Spring. The RSocket Java repository contains a number of
-{gh-rsocket-java}/tree/master/rsocket-examples[sample apps] that
-demonstrate its API and protocol features.
-
-
-
-[[rsocket-spring]]
-=== Spring Support
-
-The `spring-messaging` module contains the following:
-
-* <<rsocket-requester>> -- fluent API to make requests through an `io.rsocket.RSocket`
-  with data and metadata encoding/decoding.
-* <<rsocket-annot-responders>> -- `@MessageMapping` annotated handler methods for
-  responding.
-
-The `spring-web` module contains `Encoder` and `Decoder` implementations such as Jackson
-CBOR/JSON, and Protobuf that RSocket applications will likely need. It also contains the
-`PathPatternParser` that can be plugged in for efficient route matching.
-
-Spring Boot 2.2 supports standing up an RSocket server over TCP or WebSocket, including
-the option to expose RSocket over WebSocket in a WebFlux server. There is also client
-support and auto-configuration for an `RSocketRequester.Builder` and `RSocketStrategies`.
-See the
-https://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#boot-features-rsocket[RSocket section]
-in the Spring Boot reference for more details.
-
-Spring Security 5.2 provides RSocket support.
-
-Spring Integration 5.2 provides inbound and outbound gateways to interact with RSocket
-clients and servers. See the Spring Integration Reference Manual for more details.
-
-Spring Cloud Gateway supports RSocket connections.
-
-
-
-[[rsocket-requester]]
-== RSocketRequester
-
-`RSocketRequester` provides a fluent API to perform RSocket requests, accepting and
-returning objects for data and metadata instead of low level data buffers. It can be used
-symmetrically, to make requests from clients and to make requests from servers.
-
-
-[[rsocket-requester-client]]
-=== Client Requester
-
-To obtain an `RSocketRequester` on the client side is to connect to a server which involves
-sending an RSocket `SETUP` frame with connection settings. `RSocketRequester` provides a
-builder that helps to prepare an `io.rsocket.core.RSocketConnector` including connection
-settings for the `SETUP` frame.
-
-This is the most basic way to connect with default settings:
-
-[source,java,indent=0,subs="verbatim,quotes",role="primary"]
-.Java
----
-	RSocketRequester requester = RSocketRequester.builder().tcp("localhost", 7000);
-
-	URI url = URI.create("https://example.org:8080/rsocket");
-	RSocketRequester requester = RSocketRequester.builder().webSocket(url);
----
-
-[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
-.Kotlin
----
-	val requester = RSocketRequester.builder().tcp("localhost", 7000)
-
-	URI url = URI.create("https://example.org:8080/rsocket");
-	val requester = RSocketRequester.builder().webSocket(url)
----
-
-The above does not connect immediately. When requests are made, a shared connection is
-established transparently and used.
-
-
-[[rsocket-requester-client-setup]]
-==== Connection Setup
-
-`RSocketRequester.Builder` provides the following to customize the initial `SETUP` frame:
-
-* `dataMimeType(MimeType)` -- set the mime type for data on the connection.
-* `metadataMimeType(MimeType)` -- set the mime type for metadata on the connection.
-* `setupData(Object)` -- data to include in the `SETUP`.
-* `setupRoute(String, Object...)` -- route in the metadata to include in the `SETUP`.
-* `setupMetadata(Object, MimeType)` -- other metadata to include in the `SETUP`.
-
-For data, the default mime type is derived from the first configured `Decoder`. For
-metadata, the default mime type is
-{gh-rsocket-extensions}/CompositeMetadata.md[composite metadata] which allows multiple
-metadata value and mime type pairs per request. Typically both don't need to be changed.
-
-Data and metadata in the `SETUP` frame is optional. On the server side,
-<<rsocket-annot-connectmapping>> methods can be used to handle the start of a
-connection and the content of the `SETUP` frame. Metadata may be used for connection
-level security.
-
-
-[[rsocket-requester-client-strategies]]
-==== Strategies
-
-`RSocketRequester.Builder` accepts `RSocketStrategies` to configure the requester.
-You'll need to use this to provide encoders and decoders for (de)-serialization of data and
-metadata values. By default only the basic codecs from `spring-core` for `String`,
-`byte[]`, and `ByteBuffer` are registered. Adding `spring-web` provides access to more that
-can be registered as follows:
-
-[source,java,indent=0,subs="verbatim,quotes",role="primary"]
-.Java
----
-	RSocketStrategies strategies = RSocketStrategies.builder()
-		.encoders(encoders -> encoders.add(new Jackson2CborEncoder()))
-		.decoders(decoders -> decoders.add(new Jackson2CborDecoder()))
-		.build();
-
-	RSocketRequester requester = RSocketRequester.builder()
-		.rsocketStrategies(strategies)
-		.tcp("localhost", 7000);
----
-
-[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
-.Kotlin
----
-	val strategies = RSocketStrategies.builder()
-			.encoders { it.add(Jackson2CborEncoder()) }
-			.decoders { it.add(Jackson2CborDecoder()) }
-			.build()
-
-	val requester = RSocketRequester.builder()
-			.rsocketStrategies(strategies)
-			.tcp("localhost", 7000)
----
-
-`RSocketStrategies` is designed for re-use. In some scenarios, e.g. client and server in
-the same application, it may be preferable to declare it in Spring configuration.
-
-
-[[rsocket-requester-client-responder]]
-==== Client Responders
-
-`RSocketRequester.Builder` can be used to configure responders to requests from the
-server.
-
-You can use annotated handlers for client-side responding based on the same
-infrastructure that's used on a server, but registered programmatically as follows:
-
-[source,java,indent=0,subs="verbatim,quotes",role="primary"]
-.Java
----
-	RSocketStrategies strategies = RSocketStrategies.builder()
-		.routeMatcher(new PathPatternRouteMatcher())  // <1>
-		.build();
-
-	SocketAcceptor responder =
-		RSocketMessageHandler.responder(strategies, new ClientHandler()); // <2>
-
-	RSocketRequester requester = RSocketRequester.builder()
-		.rsocketConnector(connector -> connector.acceptor(responder)) // <3>
-		.tcp("localhost", 7000);
----
-<1> Use `PathPatternRouteMatcher`, if `spring-web` is present, for efficient
-    route matching.
-<2> Create a responder from a class with `@MessageMapping` and/or `@ConnectMapping` methods.
-<3> Register the responder.
-
-[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
-.Kotlin
----
-	val strategies = RSocketStrategies.builder()
-			.routeMatcher(PathPatternRouteMatcher())  // <1>
-			.build()
-
-	val responder =
-		RSocketMessageHandler.responder(strategies, new ClientHandler()); // <2>
-
-	val requester = RSocketRequester.builder()
-			.rsocketConnector { it.acceptor(responder) } // <3>
-			.tcp("localhost", 7000)
----
-<1> Use `PathPatternRouteMatcher`, if `spring-web` is present, for efficient
-route matching.
-<2> Create a responder from a class with `@MessageMapping` and/or `@ConnectMapping` methods.
-<3> Register the responder.
-
-Note the above is only a shortcut designed for programmatic registration of client
-responders. For alternative scenarios, where client responders are in Spring configuration,
-you can still declare `RSocketMessageHandler` as a Spring bean and then apply as follows:
-
-[source,java,indent=0,subs="verbatim,quotes",role="primary"]
-.Java
----
-	ApplicationContext context = ... ;
-	RSocketMessageHandler handler = context.getBean(RSocketMessageHandler.class);
-
-	RSocketRequester requester = RSocketRequester.builder()
-		.rsocketConnector(connector -> connector.acceptor(handler.responder()))
-		.tcp("localhost", 7000);
----
-
-[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
-.Kotlin
----
-	import org.springframework.beans.factory.getBean
-
-	val context: ApplicationContext = ...
-	val handler = context.getBean<RSocketMessageHandler>()
-
-	val requester = RSocketRequester.builder()
-			.rsocketConnector { it.acceptor(handler.responder()) }
-			.tcp("localhost", 7000)
----
-
-For the above you may also need to use `setHandlerPredicate` in `RSocketMessageHandler` to
-switch to a different strategy for detecting client responders, e.g. based on a custom
-annotation such as `@RSocketClientResponder` vs the default `@Controller`. This
-is necessary in scenarios with client and server, or multiple clients in the same
-application.
-
-See also <<rsocket-annot-responders>>, for more on the programming model.
-
-
-[[rsocket-requester-client-advanced]]
-==== Advanced
-
-`RSocketRequesterBuilder` provides a callback to expose the underlying
-`io.rsocket.core.RSocketConnector` for further configuration options for keepalive
-intervals, session resumption, interceptors, and more. You can configure options
-at that level as follows:
-
-[source,java,indent=0,subs="verbatim,quotes",role="primary"]
-.Java
----
-	RSocketRequester requester = RSocketRequester.builder()
-		.rsocketConnector(connector -> {
-			// ...
-		})
-		.tcp("localhost", 7000);
----
-
-[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
-.Kotlin
----
-	val requester = RSocketRequester.builder()
-			.rsocketConnector {
-				//...
-			}
-			.tcp("localhost", 7000)
----
-
-
-[[rsocket-requester-server]]
-=== Server Requester
-
-To make requests from a server to connected clients is a matter of obtaining the
-requester for the connected client from the server.
-
-In <<rsocket-annot-responders>>, `@ConnectMapping` and `@MessageMapping` methods support an
-`RSocketRequester` argument. Use it to access the requester for the connection. Keep in
-mind that `@ConnectMapping` methods are essentially handlers of the `SETUP` frame which
-must be handled before requests can begin. Therefore, requests at the very start must be
-decoupled from handling. For example:
-
-[source,java,indent=0,subs="verbatim,quotes",role="primary"]
-.Java
----
-	@ConnectMapping
-	Mono<Void> handle(RSocketRequester requester) {
-		requester.route("status").data("5")
-			.retrieveFlux(StatusReport.class)
-			.subscribe(bar -> { // <1>
-				// ...
-			});
-		return ... // <2>
-	}
----
-<1> Start the request asynchronously, independent from handling.
-<2> Perform handling and return completion `Mono<Void>`.
-
-[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
-.Kotlin
----
-	@ConnectMapping
-	suspend fun handle(requester: RSocketRequester) {
-		GlobalScope.launch {
-			requester.route("status").data("5").retrieveFlow<StatusReport>().collect { // <1>
-				// ...
-			}
-		}
-		/// ... <2>
-	}
----
-<1> Start the request asynchronously, independent from handling.
-<2> Perform handling in the suspending function.
-
-
-
-[[rsocket-requester-requests]]
-=== Requests
-
-Once you have a <<rsocket-requester-client,client>> or
-<<rsocket-requester-server,server>> requester, you can make requests as follows:
-
-[source,java,indent=0,subs="verbatim,quotes",role="primary"]
-.Java
----
-	ViewBox viewBox = ... ;
-
-	Flux<AirportLocation> locations = requester.route("locate.radars.within") // <1>
-			.data(viewBox) // <2>
-			.retrieveFlux(AirportLocation.class); // <3>
-
----
-<1> Specify a route to include in the metadata of the request message.
-<2> Provide data for the request message.
-<3> Declare the expected response.
-
-[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
-.Kotlin
----
-	val viewBox: ViewBox = ...
-
-	val locations = requester.route("locate.radars.within") // <1>
-			.data(viewBox) // <2>
-			.retrieveFlow<AirportLocation>() // <3>
----
-<1> Specify a route to include in the metadata of the request message.
-<2> Provide data for the request message.
-<3> Declare the expected response.
-
-The interaction type is determined implicitly from the cardinality of the input and
-output. The above example is a `Request-Stream` because one value is sent and a stream
-of values is received. For the most part you don't need to think about this as long as the
-choice of input and output matches an RSocket interaction type and the types of input and
-output expected by the responder. The only example of an invalid combination is many-to-one.
-
-The `data(Object)` method also accepts any Reactive Streams `Publisher`, including
-`Flux` and `Mono`, as well as any other producer of value(s) that is registered in the
-`ReactiveAdapterRegistry`. For a multi-value `Publisher` such as `Flux` which produces the
-same types of values, consider using one of the overloaded `data` methods to avoid having
-type checks and `Encoder` lookup on every element:
-
-[source,java,indent=0,subs="verbatim,quotes"]
----
-data(Object producer, Class<?> elementClass);
-data(Object producer, ParameterizedTypeReference<?> elementTypeRef);
----
-
-The `data(Object)` step is optional. Skip it for requests that don't send data:
-
-[source,java,indent=0,subs="verbatim,quotes",role="primary"]
-.Java
----
-	Mono<AirportLocation> location = requester.route("find.radar.EWR"))
-		.retrieveMono(AirportLocation.class);

-[[rsocket-annot-responders]]
-== Annotated Responders
-
-RSocket responders can be implemented as `@MessageMapping` and `@ConnectMapping` methods.
-`@MessageMapping` methods handle individual requests while `@ConnectMapping` methods handle
-connection-level events (setup and metadata push). Annotated responders are supported
-symmetrically, for responding from the server side and for responding from the client side.
-
-
-
-[[rsocket-annot-responders-server]]
-=== Server Responders
-
-To use annotated responders on the server side, add `RSocketMessageHandler` to your Spring
-configuration to detect `@Controller` beans with `@MessageMapping` and `@ConnectMapping`
-methods:
-
-[source,java,indent=0,subs="verbatim,quotes",role="primary"]
-.Java
----
-	@Configuration
-	static class ServerConfig {
-
-		@Bean
-		public RSocketMessageHandler rsocketMessageHandler() {
-			RSocketMessageHandler handler = new RSocketMessageHandler();
-			handler.routeMatcher(new PathPatternRouteMatcher());
-			return handler;
-		}
-	}
----
-[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
-.Kotlin
----
-	@Configuration
-	class ServerConfig {
-
-		@Bean
-		fun rsocketMessageHandler() = RSocketMessageHandler().apply {
-			routeMatcher = PathPatternRouteMatcher()
-		}
-	}
----
-
-Then start an RSocket server through the Java RSocket API and plug the
-`RSocketMessageHandler` for the responder as follows:
-
-[source,java,indent=0,subs="verbatim,quotes",role="primary"]
-.Java
----
-	ApplicationContext context = ... ;
-	RSocketMessageHandler handler = context.getBean(RSocketMessageHandler.class);
-
-	CloseableChannel server =
-		RSocketServer.create(handler.responder())
-			.bind(TcpServerTransport.create("localhost", 7000))
-			.block();
----
-[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
-.Kotlin
----
-	import org.springframework.beans.factory.getBean
-
-	val context: ApplicationContext = ...
-	val handler = context.getBean<RSocketMessageHandler>()
-
-	val server = RSocketServer.create(handler.responder())
-			.bind(TcpServerTransport.create("localhost", 7000))
-			.awaitSingle()
----
-
-`RSocketMessageHandler` supports
-{gh-rsocket-extensions}/CompositeMetadata.md[composite] and
-{gh-rsocket-extensions}/Routing.md[routing] metadata by default. You can set its
-<<rsocket-metadata-extractor>> if you need to switch to a
-different mime type or register additional metadata mime types.
-
-You'll need to set the `Encoder` and `Decoder` instances required for metadata and data
-formats to support. You'll likely need the `spring-web` module for codec implementations.
-
-By default `SimpleRouteMatcher` is used for matching routes via `AntPathMatcher`.
-We recommend plugging in the `PathPatternRouteMatcher` from `spring-web` for
-efficient route matching. RSocket routes can be hierarchical but are not URL paths.
-Both route matchers are configured to use "." as separator by default and there is no URL
-decoding as with HTTP URLs.
-
-`RSocketMessageHandler` can be configured via `RSocketStrategies` which may be useful if
-you need to share configuration between a client and a server in the same process:
-
-[source,java,indent=0,subs="verbatim,quotes",role="primary"]
-.Java
----
-	@Configuration
-	static class ServerConfig {
-
-		@Bean
-		public RSocketMessageHandler rsocketMessageHandler() {

-			handler.setRSocketStrategies(rsocketStrategies());
-			return handler;
-		}
-
-		@Bean
-		public RSocketStrategies rsocketStrategies() {
-			return RSocketStrategies.builder()
-				.encoders(encoders -> encoders.add(new Jackson2CborEncoder()))
-				.decoders(decoders -> decoders.add(new Jackson2CborDecoder()))
-				.routeMatcher(new PathPatternRouteMatcher())

-[[rsocket-annot-responders-client]]
-=== Client Responders
-
-Annotated responders on the client side need to be configured in the
-`RSocketRequester.Builder`. For details, see
-<<rsocket-requester-client-responder>>.
-
-
-
-[[rsocket-annot-messagemapping]]
-=== @MessageMapping
-
-Once <<rsocket-annot-responders-server,server>> or
-<<rsocket-annot-responders-client,client>> responder configuration is in place,
-`@MessageMapping` methods can be used as follows:
-
-[source,java,indent=0,subs="verbatim,quotes",role="primary"]
-.Java
----
-	@Controller
-	public class RadarsController {
-
-		@MessageMapping("locate.radars.within")

-	}
----

----
-@Controller
-class RadarsController {
-
-	@MessageMapping("locate.radars.within")
-	fun radars(request: MapRequest): Flow<AirportLocation> {
-		// ...
-	}
-}
----
-
-The above `@MessageMapping` method responds to a Request-Stream interaction having the
-route "locate.radars.within". It supports a flexible method signature with the option to
-use the following method arguments:
-
-[cols="1,3",options="header"]
-|===
-| Method Argument
-| Description
-
-| `@Payload`
-| The payload of the request. This can be a concrete value of asynchronous types like
-  `Mono` or `Flux`.
-
-  *Note:* Use of the annotation is optional. A method argument that is not a simple type
-  and is not any of the other supported arguments, is assumed to be the expected payload.
-
-| `RSocketRequester`
-| Requester for making requests to the remote end.
-
-| `@DestinationVariable`
-| Value extracted from the route based on variables in the mapping pattern, e.g.
-  pass:q[`@MessageMapping("find.radar.{id}")`].
-
-| `@Header`
-| Metadata value registered for extraction as described in <<rsocket-metadata-extractor>>.
-
-| `@Headers Map<String, Object>`
-| All metadata values registered for extraction as described in <<rsocket-metadata-extractor>>.
-
-|===
-
-The return value is expected to be one or more Objects to be serialized as response
-payloads. That can be asynchronous types like `Mono` or `Flux`, a concrete value, or
-either `void` or a no-value asynchronous type such as `Mono<Void>`.
-
-The RSocket interaction type that an `@MessageMapping` method supports is determined from
-the cardinality of the input (i.e. `@Payload` argument) and of the output, where
-cardinality means the following:
-
-[%autowidth]
-[cols=2*,options="header"]
-|===
-| Cardinality
-| Description
-
-| 1
-| Either an explicit value, or a single-value asynchronous type such as `Mono<T>`.
-
-| Many
-| A multi-value asynchronous type such as `Flux<T>`.
-
-| 0
-| For input this means the method does not have an `@Payload` argument.
-
-  For output this is `void` or a no-value asynchronous type such as `Mono<Void>`.
-|===
-
-The table below shows all input and output cardinality combinations and the corresponding
-interaction type(s):

-[[rsocket-annot-connectmapping]]
-=== @ConnectMapping
-
-`@ConnectMapping` handles the `SETUP` frame at the start of an RSocket connection, and
-any subsequent metadata push notifications through the `METADATA_PUSH` frame, i.e.
-`metadataPush(Payload)` in `io.rsocket.RSocket`.
-
-`@ConnectMapping` methods support the same arguments as
-<<rsocket-annot-messagemapping>> but based on metadata and data from the `SETUP` and
-`METADATA_PUSH` frames. `@ConnectMapping` can have a pattern to narrow handling to
-specific connections that have a route in the metadata, or if no patterns are declared
-then all connections match.
-
-`@ConnectMapping` methods cannot return data and must be declared with `void` or
-`Mono<Void>` as the return value. If handling returns an error for a new
-connection then the connection is rejected. Handling must not be held up to make
-requests to the `RSocketRequester` for the connection. See
-<<rsocket-requester-server>> for details.
-
-
-
-
-[[rsocket-metadata-extractor]]
-== MetadataExtractor
-
-Responders must interpret metadata.
-{gh-rsocket-extensions}/CompositeMetadata.md[Composite metadata] allows independently
-formatted metadata values (e.g. for routing, security, tracing) each with its own mime
-type. Applications need a way to configure metadata mime types to support, and a way
-to access extracted values.
-
-`MetadataExtractor` is a contract to take serialized metadata and return decoded
-name-value pairs that can then be accessed like headers by name, for example via `@Header`
-in annotated handler methods.
-
-`DefaultMetadataExtractor` can be given `Decoder` instances to decode metadata. Out of
-the box it has built-in support for
-{gh-rsocket-extensions}/Routing.md["message/x.rsocket.routing.v0"] which it decodes to
-`String` and saves under the "route" key. For any other mime type you'll need to provide
-a `Decoder` and register the mime type as follows:
-
-[source,java,indent=0,subs="verbatim,quotes",role="primary"]
-.Java
----
-	DefaultMetadataExtractor extractor = new DefaultMetadataExtractor(metadataDecoders);
-	extractor.metadataToExtract(fooMimeType, Foo.class, "foo");
----
-[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
-.Kotlin
----
-	import org.springframework.messaging.rsocket.metadataToExtract
-
-	val extractor = DefaultMetadataExtractor(metadataDecoders)
-	extractor.metadataToExtract<Foo>(fooMimeType, "foo")
----
-
-Composite metadata works well to combine independent metadata values. However the
-requester might not support composite metadata, or may choose not to use it. For this,
-`DefaultMetadataExtractor` may needs custom logic to map the decoded value to the output
-map. Here is an example where JSON is used for metadata:
-
-[source,java,indent=0,subs="verbatim,quotes",role="primary"]
-.Java
----
-	DefaultMetadataExtractor extractor = new DefaultMetadataExtractor(metadataDecoders);
-	extractor.metadataToExtract(
-		MimeType.valueOf("application/vnd.myapp.metadata+json"),
-		new ParameterizedTypeReference<Map<String,String>>() {},
-		(jsonMap, outputMap) -> {
-			outputMap.putAll(jsonMap);
-		});
----
-[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
-.Kotlin
----
-	import org.springframework.messaging.rsocket.metadataToExtract
-
-	val extractor = DefaultMetadataExtractor(metadataDecoders)
-	extractor.metadataToExtract<Map<String, String>>(MimeType.valueOf("application/vnd.myapp.metadata+json")) { jsonMap, outputMap ->
-		outputMap.putAll(jsonMap)
-	}
----
-
-When configuring `MetadataExtractor` through `RSocketStrategies`, you can let
-`RSocketStrategies.Builder` create the extractor with the configured decoders, and
-simply use a callback to customize registrations as follows:
-
-[source,java,indent=0,subs="verbatim,quotes",role="primary"]
-.Java
----
-	RSocketStrategies strategies = RSocketStrategies.builder()
-		.metadataExtractorRegistry(registry -> {
-			registry.metadataToExtract(fooMimeType, Foo.class, "foo");
-			// ...
-		})
-		.build();
----
-[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]

----
-	import org.springframework.messaging.rsocket.metadataToExtract

-[[rsocket-interface]]
-== RSocket Interface
-
-The Spring Framework lets you define an RSocket service as a Java interface with annotated
-methods for RSocket exchanges. You can then generate a proxy that implements this interface
-and performs the exchanges. This helps to simplify RSocket remote access by wrapping the
-use of the underlying <<rsocket-requester>>.
-
-One, declare an interface with `@RSocketExchange` methods:
-
-[source,java,indent=0,subs="verbatim,quotes"]
----

-
-		@RSocketExchange("radars")
-		Flux<AirportLocation> getRadars(@Payload MapRequest request);
-
-		// more RSocket exchange methods...
-
-	}
----

-method parameters:
-
-[cols="1,2", options="header"]
-|===
-| Method argument | Description
-
-| `@DestinationVariable`
-| Add a route variable to pass to `RSocketRequester` along with the route from the
-  `@RSocketExchange` annotation in order to expand template placeholders in the route.
-  This variable can be a String or any Object, which is then formatted via `toString()`.
-
-| `@Payload`
-| Set the input payload(s) for the request. This can be a concrete value, or any producer
-  of values that can be adapted to a Reactive Streams `Publisher` via
-  `ReactiveAdapterRegistry`
-
-| `Object`, if followed by `MimeType`
-| The value for a metadata entry in the input payload. This can be any `Object` as long
-  as the next argument is the metadata entry `MimeType`. The value can be a concrete
-  value or any producer of a single value that can be adapted to a Reactive Streams
-  `Publisher` via `ReactiveAdapterRegistry`.
-
-| `MimeType`
-| The `MimeType` for a metadata entry. The preceding method argument is expected to be
-  the metadata value.

-= Integration Testing
-
-It is important to be able to perform some integration testing without requiring
-deployment to your application server or connecting to other enterprise infrastructure.
-Doing so lets you test things such as:
-
-* The correct wiring of your Spring IoC container contexts.
-* Data access using JDBC or an ORM tool. This can include such things as the correctness
-  of SQL statements, Hibernate queries, JPA entity mappings, and so forth.
-
-The Spring Framework provides first-class support for integration testing in the
-`spring-test` module. The name of the actual JAR file might include the release version
-and might also be in the long `org.springframework.test` form, depending on where you get
-it from (see the <<core.adoc#beans-dependencies, section on Dependency Management>>
-for an explanation). This library includes the `org.springframework.test` package, which
-contains valuable classes for integration testing with a Spring container. This testing
-does not rely on an application server or other deployment environment. Such tests are
-slower to run than unit tests but much faster than the equivalent Selenium tests or
-remote tests that rely on deployment to an application server.
-
-Unit and integration testing support is provided in the form of the annotation-driven
-<<testcontext-framework, Spring TestContext Framework>>. The TestContext framework is
-agnostic of the actual testing framework in use, which allows instrumentation of tests
-in various environments, including JUnit, TestNG, and others.
-
-The following section provides an overview of the high-level goals of Spring's
-integration support, and the rest of this chapter then focuses on dedicated topics:
-
-* <<integration-testing-support-jdbc>>
-* <<testcontext-framework>>
-* <<webtestclient>>
-* <<spring-mvc-test-framework>>
-* <<spring-mvc-test-client>>
-* <<integration-testing-annotations>>
-
-
-
-[[integration-testing-goals]]
-== Goals of Integration Testing
-
-Spring's integration testing support has the following primary goals:
-
-* To manage <<testing-ctx-management, Spring IoC container caching>> between tests.
-* To provide <<testing-fixture-di, Dependency Injection of test fixture instances>>.
-* To provide <<testing-tx, transaction management>> appropriate to integration testing.
-* To supply <<testing-support-classes, Spring-specific base classes>> that assist
-  developers in writing integration tests.
-
-The next few sections describe each goal and provide links to implementation and
-configuration details.
-
-
-[[testing-ctx-management]]
-=== Context Management and Caching
-
-The Spring TestContext Framework provides consistent loading of Spring
-`ApplicationContext` instances and `WebApplicationContext` instances as well as caching
-of those contexts. Support for the caching of loaded contexts is important, because
-startup time can become an issue -- not because of the overhead of Spring itself, but
-because the objects instantiated by the Spring container take time to instantiate. For
-example, a project with 50 to 100 Hibernate mapping files might take 10 to 20 seconds to
-load the mapping files, and incurring that cost before running every test in every test
-fixture leads to slower overall test runs that reduce developer productivity.
-
-Test classes typically declare either an array of resource locations for XML or Groovy
-configuration metadata -- often in the classpath -- or an array of component classes that
-is used to configure the application. These locations or classes are the same as or
-similar to those specified in `web.xml` or other configuration files for production
-deployments.
-
-By default, once loaded, the configured `ApplicationContext` is reused for each test.
-Thus, the setup cost is incurred only once per test suite, and subsequent test execution
-is much faster. In this context, the term "`test suite`" means all tests run in the same
-JVM -- for example, all tests run from an Ant, Maven, or Gradle build for a given project
-or module. In the unlikely case that a test corrupts the application context and requires
-reloading (for example, by modifying a bean definition or the state of an application
-object) the TestContext framework can be configured to reload the configuration and
-rebuild the application context before executing the next test.
-
-See <<testcontext-ctx-management>> and <<testcontext-ctx-management-caching>> with the
-TestContext framework.
-
-
-[[testing-fixture-di]]
-=== Dependency Injection of Test Fixtures
-
-When the TestContext framework loads your application context, it can optionally
-configure instances of your test classes by using Dependency Injection. This provides a
-convenient mechanism for setting up test fixtures by using preconfigured beans from your
-application context. A strong benefit here is that you can reuse application contexts
-across various testing scenarios (for example, for configuring Spring-managed object
-graphs, transactional proxies, `DataSource` instances, and others), thus avoiding the
-need to duplicate complex test fixture setup for individual test cases.
-
-As an example, consider a scenario where we have a class (`HibernateTitleRepository`)
-that implements data access logic for a `Title` domain entity. We want to write
-integration tests that test the following areas:
-
-* The Spring configuration: Basically, is everything related to the configuration of the
-  `HibernateTitleRepository` bean correct and present?
-* The Hibernate mapping file configuration: Is everything mapped correctly and are the
-  correct lazy-loading settings in place?
-* The logic of the `HibernateTitleRepository`: Does the configured instance of this class
-  perform as anticipated?
-
-See dependency injection of test fixtures with the
-<<testcontext-fixture-di, TestContext framework>>.
-
-
-[[testing-tx]]
-=== Transaction Management
-
-One common issue in tests that access a real database is their effect on the state of the
-persistence store. Even when you use a development database, changes to the state may
-affect future tests. Also, many operations -- such as inserting or modifying persistent
-data -- cannot be performed (or verified) outside of a transaction.
-
-The TestContext framework addresses this issue. By default, the framework creates and
-rolls back a transaction for each test. You can write code that can assume the existence
-of a transaction. If you call transactionally proxied objects in your tests, they behave
-correctly, according to their configured transactional semantics. In addition, if a test
-method deletes the contents of selected tables while running within the transaction
-managed for the test, the transaction rolls back by default, and the database returns to
-its state prior to execution of the test. Transactional support is provided to a test by
-using a `PlatformTransactionManager` bean defined in the test's application context.
-
-If you want a transaction to commit (unusual, but occasionally useful when you want a
-particular test to populate or modify the database), you can tell the TestContext
-framework to cause the transaction to commit instead of roll back by using the
-<<integration-testing-annotations, `@Commit`>> annotation.
-
-See transaction management with the <<testcontext-tx, TestContext framework>>.
-
-
-[[testing-support-classes]]
-=== Support Classes for Integration Testing
-
-The Spring TestContext Framework provides several `abstract` support classes that
-simplify the writing of integration tests. These base test classes provide well-defined
-hooks into the testing framework as well as convenient instance variables and methods,
-which let you access:
-
-* The `ApplicationContext`, for performing explicit bean lookups or testing the state of
-  the context as a whole.
-* A `JdbcTemplate`, for executing SQL statements to query the database. You can use such
-  queries to confirm database state both before and after execution of database-related
-  application code, and Spring ensures that such queries run in the scope of the same
-  transaction as the application code. When used in conjunction with an ORM tool, be sure
-  to avoid <<testcontext-tx-false-positives, false positives>>.
-
-In addition, you may want to create your own custom, application-wide superclass with
-instance variables and methods specific to your project.
-
-See support classes for the <<testcontext-support-classes, TestContext framework>>.

-= Testing Client Applications
-
-You can use client-side tests to test code that internally uses the `RestTemplate`. The
-idea is to declare expected requests and to provide "`stub`" responses so that you can

-In the preceding example, `MockRestServiceServer` (the central class for client-side REST
-tests) configures the `RestTemplate` with a custom `ClientHttpRequestFactory` that
-asserts actual requests against expectations and returns "`stub`" responses. In this
-case, we expect a request to `/greeting` and want to return a 200 response with
-`text/plain` content. We can define additional expected requests and stub responses as
-needed. When we define expected requests and stub responses, the `RestTemplate` can be
-used in client-side code as usual. At the end of testing, `mockServer.verify()` can be
-used to verify that all expectations have been satisfied.
-
-By default, requests are expected in the order in which expectations were declared. You
-can set the `ignoreExpectOrder` option when building the server, in which case all
-expectations are checked (in order) to find a match for a given request. That means
-requests are allowed to come in any order. The following example uses `ignoreExpectOrder`:
-
-[source,java,indent=0,subs="verbatim,quotes",role="primary"]
-.Java
----
-	server = MockRestServiceServer.bindTo(restTemplate).ignoreExpectOrder(true).build();
----
-[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
-.Kotlin
----
-	server = MockRestServiceServer.bindTo(restTemplate).ignoreExpectOrder(true).build()
----
-
-Even with unordered requests by default, each request is allowed to run once only.
-The `expect` method provides an overloaded variant that accepts an `ExpectedCount`
-argument that specifies a count range (for example, `once`, `manyTimes`, `max`, `min`,
-`between`, and so on). The following example uses `times`:
-
-[source,java,indent=0,subs="verbatim,quotes",role="primary"]
-.Java
----
-	RestTemplate restTemplate = new RestTemplate();
-
-	MockRestServiceServer mockServer = MockRestServiceServer.bindTo(restTemplate).build();
-	mockServer.expect(times(2), requestTo("/something")).andRespond(withSuccess());
-	mockServer.expect(times(3), requestTo("/somewhere")).andRespond(withSuccess());
-
-	// ...
-
-	mockServer.verify();
----
-[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
-.Kotlin
----
-	val restTemplate = RestTemplate()
-
-	val mockServer = MockRestServiceServer.bindTo(restTemplate).build()
-	mockServer.expect(times(2), requestTo("/something")).andRespond(withSuccess())
-	mockServer.expect(times(3), requestTo("/somewhere")).andRespond(withSuccess())
-
-	// ...
-
-	mockServer.verify()
----
-
-Note that, when `ignoreExpectOrder` is not set (the default), and, therefore, requests
-are expected in order of declaration, then that order applies only to the first of any
-expected request. For example if "/something" is expected two times followed by
-"/somewhere" three times, then there should be a request to "/something" before there is
-a request to "/somewhere", but, aside from that subsequent "/something" and "/somewhere",
-requests can come at any time.
-
-As an alternative to all of the above, the client-side test support also provides a
-`ClientHttpRequestFactory` implementation that you can configure into a `RestTemplate` to
-bind it to a `MockMvc` instance. That allows processing requests using actual server-side
-logic but without running a server. The following example shows how to do so:
-
-[source,java,indent=0,subs="verbatim,quotes",role="primary"]
-.Java
----
-	MockMvc mockMvc = MockMvcBuilders.webAppContextSetup(this.wac).build();
-	this.restTemplate = new RestTemplate(new MockMvcClientHttpRequestFactory(mockMvc));
-
-	// Test code that uses the above RestTemplate ...
----
-[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
-.Kotlin
----
-	val mockMvc = MockMvcBuilders.webAppContextSetup(this.wac).build()
-	restTemplate = RestTemplate(MockMvcClientHttpRequestFactory(mockMvc))
-
-	// Test code that uses the above RestTemplate ...

-== Static Imports
-
-As with server-side tests, the fluent API for client-side tests requires a few static
-imports. Those are easy to find by searching for `MockRest*`. Eclipse users should add
-`MockRestRequestMatchers.{asterisk}` and `MockRestResponseCreators.{asterisk}` as
-"`favorite static members`" in the Eclipse preferences under Java -> Editor -> Content
-Assist -> Favorites. That allows using content assist after typing the first character of
-the static method name. Other IDEs (such IntelliJ) may not require any additional
-configuration. Check for the support for code completion on static members.
