= Contributor Code of Conduct
|
||||
|
||||
As contributors and maintainers of this project, and in the interest of fostering an open
|
||||
and welcoming community, we pledge to respect all people who contribute through reporting
|
||||
issues, posting feature requests, updating documentation, submitting pull requests or
|
||||
patches, and other activities.
|
||||
|
||||
We are committed to making participation in this project a harassment-free experience for
|
||||
everyone, regardless of level of experience, gender, gender identity and expression,
|
||||
sexual orientation, disability, personal appearance, body size, race, ethnicity, age,
|
||||
religion, or nationality.
|
||||
|
||||
Examples of unacceptable behavior by participants include:
|
||||
|
||||
* The use of sexualized language or imagery
|
||||
* Personal attacks
|
||||
* Trolling or insulting/derogatory comments
|
||||
* Public or private harassment
|
||||
* Publishing other's private information, such as physical or electronic addresses,
|
||||
without explicit permission
|
||||
* Other unethical or unprofessional conduct
|
||||
|
||||
Project maintainers have the right and responsibility to remove, edit, or reject comments,
|
||||
commits, code, wiki edits, issues, and other contributions that are not aligned to this
|
||||
Code of Conduct, or to ban temporarily or permanently any contributor for other behaviors
|
||||
that they deem inappropriate, threatening, offensive, or harmful.
|
||||
|
||||
By adopting this Code of Conduct, project maintainers commit themselves to fairly and
|
||||
consistently applying these principles to every aspect of managing this project. Project
|
||||
maintainers who do not follow or enforce the Code of Conduct may be permanently removed
|
||||
from the project team.
|
||||
|
||||
This Code of Conduct applies both within project spaces and in public spaces when an
|
||||
individual is representing the project or its community.
|
||||
|
||||
Instances of abusive, harassing, or otherwise unacceptable behavior may be reported by
|
||||
contacting a project maintainer at spring-code-of-conduct@pivotal.io . All complaints will
|
||||
be reviewed and investigated and will result in a response that is deemed necessary and
|
||||
appropriate to the circumstances. Maintainers are obligated to maintain confidentiality
|
||||
with regard to the reporter of an incident.
|
||||
|
||||
This Code of Conduct is adapted from the

* `final` methods cannot be advised, because they cannot be overridden.

* Methods that are not visible – for example, package-private methods in a parent class

from a different package – cannot be advised because they are effectively private.

* The constructor of your proxied object will not be called twice, since the CGLIB proxy

instance is created through Objenesis. However, if your JVM does not allow for
|

constructor bypassing, you might see double invocations and corresponding debug log

* Your CGLIB proxy usage may face limitations with the Java Module System. As a typical
|

case, you cannot create a CGLIB proxy for a class from the `java.lang` package when

deploying on the module path. Such cases require a JVM bootstrap flag

`--add-opens=java.base/java.lang=ALL-UNNAMED` which is not available for modules.

|
||||
=== Programmatic Bean Registration
|
||||
|
||||
The AOT engine takes care of the `@Configuration` model and any callback that might be
|
||||
invoked as part of processing your configuration. If you need to register additional
|
||||
beans programmatically, make sure to use a `BeanDefinitionRegistry` to register
|
||||
bean definitions.
|
||||
|
||||
This can typically be done via a `BeanDefinitionRegistryPostProcessor`. Note that, if it
|
||||
is registered itself as a bean, it will be invoked again at runtime unless you make
|
||||
sure to implement `BeanFactoryInitializationAotProcessor` as well. A more idiomatic
|
||||
way is to implement `ImportBeanDefinitionRegistrar` and register it using `@Import` on
|
||||
one of your configuration classes. This invokes your custom code as part of configuration
|
||||
class parsing.
|
||||
|
||||
If you declare additional beans programmatically using a different callback, they are
|
||||
likely not going to be handled by the AOT engine, and therefore no hints are going to be
|
||||
generated for them. Depending on the environment, those beans may not be registered at
|
||||
all. For instance, classpath scanning does not work in a native image as there is no
|
||||
notion of a classpath. For cases like this, it is crucial that the scanning happens at
|
||||
build time.

[[aot.bestpractices.constructors]]
|
||||
=== Avoid Multiple Constructors
|
||||
|
||||
The container is able to choose the most appropriate constructor to use based on several candidates.
|
||||
However, relying on that is not a best practice, and flagging the preferred constructor with `@Autowired` if necessary is preferred.
|
||||
|
||||
In case you are working on a code base that you cannot modify, you can set the {spring-framework-api}/beans/factory/support/AbstractBeanDefinition.html#PREFERRED_CONSTRUCTORS_ATTRIBUTE[`preferredConstructors` attribute] on the related bean definition to indicate which constructor should be used.
|
||||
|
||||
[[aot.bestpractices.complex-data-structures]]
|
||||
=== Avoid Complex Data Structures for Constructor Parameters and Properties
|
||||
|
||||
When crafting a `RootBeanDefinition` programmatically, you are not constrained in terms of types that you can use.
|
||||
For instance, you may have a custom `record` with several properties that your bean takes as a constructor argument.
|
||||
|
||||
While this works fine with the regular runtime, AOT does not know how to generate the code of your custom data structure.
|
||||
A good rule of thumb is to keep in mind that bean definitions are an abstraction on top of several models.
|
||||
Rather than using such structures, decomposing to simple types or referring to a bean that is built as such is recommended.
|
||||
|
||||
As a last resort, you can implement your own `org.springframework.aot.generate.ValueCodeGenerator$Delegate`.
|
||||
To use it, register its fully-qualified name in `META-INF/spring/aot.factories` using `org.springframework.aot.generate.ValueCodeGenerator$Delegate` as the key.
|
||||
|
||||
[[aot.bestpractices.custom-arguments]]
|
||||
=== Avoid Creating Beans with Custom Arguments
|
||||
|
||||
Spring AOT detects what needs to be done to create a bean and translates that into generated code that uses an instance supplier.
|
||||
The container also supports creating a bean with {spring-framework-api}++/beans/factory/BeanFactory.html#getBean(java.lang.String,java.lang.Object...)++[custom arguments] which can lead to several issues with AOT:
|
||||
|
||||
. The custom arguments require dynamic introspection of a matching constructor or factory method.
|
||||
Those arguments cannot be detected by AOT, so the necessary reflection hints will have to be provided manually.
|
||||
. By-passing the instance supplier means that all other optimizations after creation are skipped as well.
|
||||
For instance, autowiring on fields and methods will be skipped as they are handled in the instance supplier.
|
||||
|
||||
Rather than having prototype-scoped beans created with custom arguments, we recommend a manual factory pattern where a bean is responsible for the creation of the instance.
|
||||
|
||||
[[aot.bestpractices.circular-dependencies]]
|
||||
=== Avoid Circular Dependencies
|
||||
|
||||
Certain use cases can result in circular dependencies between one or more beans. With the
|
||||
regular runtime, it may be possible to wire those circular dependencies via `@Autowired`
|
||||
on setter methods or fields. However, an AOT-optimized context will fail to start with
|
||||
explicit circular dependencies.
|
||||
|
||||
In an AOT-optimized application, you should therefore strive to avoid circular
|
||||
dependencies. If that is not possible, you can use `@Lazy` injection points or
|
||||
`ObjectProvider` to lazily access or retrieve the necessary collaborating beans. See
|
||||
xref:core/beans/classpath-scanning.adoc#beans-factorybeans-annotations-lazy-injection-points[this tip]

for further information.

[[aot.bestpractices.factory-bean]]
|
||||
=== FactoryBean
|
||||
|
||||
`FactoryBean` should be used with care as it introduces an intermediate layer in terms of bean type resolution that may not be conceptually necessary.
|
||||
As a rule of thumb, if a `FactoryBean` instance does not hold long-term state and is not needed at a later point at runtime, it should be replaced by a regular `@Bean` factory method, possibly with a `FactoryBean` adapter layer on top (for declarative configuration purposes).

{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.

||||
|
||||
Out-of-the-box, only Spring beans are considered, but you can opt-in for scanning using

||||
{spring-framework-api}/context/annotation/ReflectiveScan.html[`@ReflectiveScan`]. In the

Scanning happens during AOT processing, and the types in the target packages do not need to have a class-level annotation to be considered.
|

This performs a _deep scan_, and the presence of `@Reflective`, either directly or as a meta-annotation, is checked on types, fields, constructors, methods, and enclosed elements.

`@RegisterReflection` can be applied to any target type at the class level, but it can also be applied directly to a method to better indicate where the hints are actually required.

||||
common types (see xref:core/validation/convert.adoc[Spring Type Conversion]), some
|
||||
conversions are supported via a convention-based algorithm that relies on reflection.
|
||||
|
||||
Specifically, if there is no explicit `Converter` registered with the `ConversionService`
|
||||
for a particular source → target type pair, the internal `ObjectToObjectConverter`
|
||||
will attempt to use conventions to convert a source object to a target type by delegating
|
||||
to a method on the source object or to a static factory method or constructor on the
|
||||
target type. Since this convention-based algorithm can be applied to arbitrary types at
|
||||
runtime, the core container is not able to infer the runtime hints necessary to support
|
||||
such reflection.
|
||||
|
||||
If you encounter convention-based conversion issues within a native image resulting from
|
||||
lacking runtime hints, you can register the necessary hints programmatically. For
|
||||
example, if your application requires a conversion from `java.time.Instant` to
|
||||
`java.sql.Timestamp` and relies on `ObjectToObjectConverter` to invoke
|
||||
`java.sql.Timestamp.from(Instant)` using reflection, you could implement a custom
|
||||
`RuntimeHintsRegitrar` to support this use case within a native image, as demonstrated in
|
||||
the following example.
|
||||
`@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.

= Annotation-based Container Configuration
|
||||
|
||||
Spring provides comprehensive support for annotation-based configuration, operating on
|
||||
metadata in the component class itself by using annotations on the relevant class,
|
||||
method, or field declaration. As mentioned in
|
||||
xref:core/beans/factory-extension.adoc#beans-factory-extension-bpp-examples-aabpp[Example: The `AutowiredAnnotationBeanPostProcessor`],
|
||||
Spring uses `BeanPostProcessors` in conjunction with annotations to make the core IOC
|
||||
container aware of specific annotations.
|
||||
.Are annotations better than XML for configuring Spring?
|
||||
****
|
||||
The introduction of annotation-based configuration raised the question of whether this
|
||||
approach is "`better`" than XML. The short answer is "`it depends.`" The long answer is
|
||||
that each approach has its pros and cons, and, usually, it is up to the developer to
|
||||
decide which strategy suits them better. Due to the way they are defined, annotations
|
||||
provide a lot of context in their declaration, leading to shorter and more concise
|
||||
configuration. However, XML excels at wiring up components without touching their source
|
||||
code or recompiling them. Some developers prefer having the wiring close to the source
|
||||
while others argue that annotated classes are no longer POJOs and, furthermore, that the
|
||||
configuration becomes decentralized and harder to control.
|
||||
|
||||
For example, the xref:core/beans/annotation-config/autowired.adoc[`@Autowired`]
|
||||
annotation provides the same capabilities as described in
|
||||
xref:core/beans/dependencies/factory-autowire.adoc[Autowiring Collaborators] but
|
||||
No matter the choice, Spring can accommodate both styles and even mix them together.
|
||||
It is worth pointing out that through its xref:core/beans/java.adoc[JavaConfig] option, Spring lets
|
||||
annotations be used in a non-invasive way, without touching the target components'
|
||||
source code and that, in terms of tooling, all configuration styles are supported by
|
||||
https://spring.io/tools[Spring Tools] for Eclipse, Visual Studio Code, and Theia.
|
||||
****
|
||||
|
||||
An alternative to XML setup is provided by annotation-based configuration, which relies
|
||||
on bytecode metadata for wiring up components instead of XML declarations. Instead of
|
||||
using XML to describe a bean wiring, the developer moves the configuration into the
|
||||
component class itself by using annotations on the relevant class, method, or field
|
||||
declaration. As mentioned in xref:core/beans/factory-extension.adoc#beans-factory-extension-bpp-examples-aabpp[Example: The `AutowiredAnnotationBeanPostProcessor`], using a
|
||||
`BeanPostProcessor` in conjunction with annotations is a common means of extending the
|
||||
Spring IoC container. For example, the xref:core/beans/annotation-config/autowired.adoc[`@Autowired`]
|
||||
annotation provides the same capabilities as described in xref:core/beans/dependencies/factory-autowire.adoc[Autowiring Collaborators] but
|
||||
with more fine-grained control and wider applicability. In addition, Spring provides
|
||||

(that is, the field name or parameter name) against the target bean names and chooses

the same-named candidate, if any (either by bean name or by associated alias).
|

|

Since version 6.1, this requires the `-parameters` Java compiler flag to be present.
|

As of 6.2, the container applies fast shortcut resolution for bean name matches,

bypassing the full type matching algorithm when the parameter name matches the

bean name and no type, qualifier or primary conditions override the match. It is

therefore recommendable for your parameter names to match the target bean names.

====
|

|
||||
As an alternative for injection by name, consider the JSR-250 `@Resource` annotation
|
||||
which is semantically defined to identify a specific target component by its unique name,

with the declared type being irrelevant for the matching process. `@Autowired` has rather

different semantics: After selecting candidate beans by type, the specified `String`

matching an `account` qualifier against beans marked with the same qualifier label).
|
||||
|
||||
For beans that are themselves defined as a collection, `Map`, or array type, `@Resource`
|
||||
is a fine solution, referring to the specific collection or array bean by unique name.

That said, as of 4.3, you can match collection, `Map`, and array types through Spring's

`@Autowired` type matching algorithm as well, as long as the element type information
|
||||
is preserved in `@Bean` return type signatures or collection inheritance hierarchies.
|
||||
In this case, you can use qualifier values to select among same-typed collections,
|
||||
as outlined in the previous paragraph.
|
||||
|
||||
`@Autowired` also considers self references for injection (that is, references back to
|
||||
the bean that is currently injected). See

xref:core/beans/annotation-config/autowired.adoc#beans-autowired-annotation-self-injection[Self Injection]

As of 4.3, `@Autowired` also considers self references for injection (that is, references
|
||||
back to the bean that is currently injected). Note that self injection is a fallback.
|
||||
Regular dependencies on other components always have precedence. In that sense, self
|
||||
references do not participate in regular candidate selection and are therefore in
|
||||
particular never primary. On the contrary, they always end up as lowest precedence.
|
||||
In practice, you should use self references as a last resort only (for example, for
|
||||
calling other methods on the same instance through the bean's transactional proxy).
|
||||
Consider factoring out the affected methods to a separate delegate bean in such a scenario.
|
||||
Alternatively, you can use `@Resource`, which may obtain a proxy back to the current bean
|
||||
by its unique name.

[NOTE]

====

Trying to inject the results from `@Bean` methods on the same configuration class is

effectively a self-reference scenario as well. Either lazily resolve such references

in the method signature where it is actually needed (as opposed to an autowired field

in the configuration class) or declare the affected `@Bean` methods as `static`,

|

`@Autowired` also considers self references for injection (that is, references back to
|
||||
the bean that is currently injected).
|
||||
|
||||
Note, however, that self injection is a fallback mechanism. Regular dependencies on other
|
||||
components always have precedence. In that sense, self references do not participate in
|
||||
regular autowiring candidate selection and are therefore in particular never primary. On
|
||||
the contrary, they always end up as lowest precedence.
|
||||
|
||||
In practice, you should use self references as a last resort only – for example, for
|
||||
calling other methods on the same instance through the bean's transactional proxy. As an
|
||||
alternative, consider factoring out the affected methods to a separate delegate bean in
|
||||
such a scenario.
|
||||
|
||||
Another alternative is to use `@Resource`, which may obtain a proxy back to the current
|
||||
bean by its unique name.
|
||||
|
||||
======
|
||||
[NOTE]
|
||||
====
|
||||
Trying to inject the results from `@Bean` methods in the same `@Configuration` class is
|
||||
effectively a self-reference scenario as well. Either lazily resolve such references
|
||||
in the method signature where it is actually needed (as opposed to an autowired field
|
||||
in the configuration class) or declare the affected `@Bean` methods as `static`,
|
||||
decoupling them from the containing configuration class instance and its lifecycle.
|
||||
Otherwise, such beans are only considered in the fallback phase, with matching beans
|
||||
on other configuration classes selected as primary candidates instead (if available).

= Container Overview
|
||||
|
||||
The `org.springframework.context.ApplicationContext` interface represents the Spring IoC
|
||||
container and is responsible for instantiating, configuring, and assembling the beans.
|
||||
The container gets its instructions on the components to instantiate, configure, and
|
||||
assemble by reading configuration metadata. The configuration metadata can be represented
|
||||
as annotated component classes, configuration classes with factory methods, or external
|
||||
XML files or Groovy scripts. With either format, you may compose your application and the
|
||||
rich interdependencies between those components.
|
||||
container and is responsible for instantiating, configuring, and assembling the
|
||||
beans. The container gets its instructions on what objects to
|
||||
instantiate, configure, and assemble by reading configuration metadata. The
|
||||
configuration metadata is represented in XML, Java annotations, or Java code. It lets
|
||||
you express the objects that compose your application and the rich interdependencies
|
||||
between those objects.
|
||||
|
||||
Several implementations of the `ApplicationContext` interface are part of core Spring.
|
||||
In stand-alone applications, it is common to create an instance of
|
||||
{spring-framework-api}/context/annotation/AnnotationConfigApplicationContext.html[`AnnotationConfigApplicationContext`]
|
||||
or {spring-framework-api}/context/support/ClassPathXmlApplicationContext.html[`ClassPathXmlApplicationContext`].
|
||||
Several implementations of the `ApplicationContext` interface are supplied
|
||||
with Spring. In stand-alone applications, it is common to create an
|
||||
instance of
|
||||
{api-spring-framework}/context/support/ClassPathXmlApplicationContext.html[`ClassPathXmlApplicationContext`]
|
||||
or {api-spring-framework}/context/support/FileSystemXmlApplicationContext.html[`FileSystemXmlApplicationContext`].
|
||||
While XML has been the traditional format for defining configuration metadata, you can
|
||||
instruct the container to use Java annotations or code as the metadata format by
|
||||
providing a small amount of XML configuration to declaratively enable support for these
|
||||
additional metadata formats.
|
||||
|
||||
In most application scenarios, explicit user code is not required to instantiate one or
|
||||
more instances of a Spring IoC container. For example, in a plain web application scenario,
|
||||
a simple boilerplate web descriptor XML in the `web.xml` file of the application suffices (see
|
||||
more instances of a Spring IoC container. For example, in a web application scenario, a
|
||||
simple eight (or so) lines of boilerplate web descriptor XML in the `web.xml` file
|
||||
of the application typically suffices (see
|
||||
xref:core/beans/context-introduction.adoc#context-create[Convenient ApplicationContext Instantiation for Web Applications]).
|
||||
In a Spring Boot scenario, the application context is implicitly bootstrapped for you
|
||||
based on common setup conventions.
|
||||
If you use the https://spring.io/tools[Spring Tools for Eclipse] (an Eclipse-powered
|
||||
development environment), you can easily create this boilerplate configuration with a
|
||||
few mouse clicks or keystrokes.
|
||||
|
||||
The following diagram shows a high-level view of how Spring works. Your application classes
|
||||
are combined with configuration metadata so that, after the `ApplicationContext` is
|
||||
created and initialized, you have a fully configured and executable system or application.

== Configuration Metadata
|
||||
|
||||
As the preceding diagram shows, the Spring IoC container consumes a form of
|
||||
configuration metadata. This configuration metadata represents how you, as an
|
||||
application developer, tell the Spring container to instantiate, configure,
|
||||
and assemble the components in your application.
|
||||
application developer, tell the Spring container to instantiate, configure, and assemble
|
||||
the objects in your application.
|
||||
|
||||
Configuration metadata is traditionally supplied in a simple and intuitive XML format,
|
||||
which is what most of this chapter uses to convey key concepts and features of the
|
||||
Spring IoC container.
|
||||
|
||||
NOTE: XML-based metadata is not the only allowed form of configuration metadata.
|
||||
The Spring IoC container itself is totally decoupled from the format in which this
|
||||
configuration metadata is actually written. These days, many developers choose
|
||||

== Naming Autodetected Components
|
||||
|
||||
When a component is autodetected as part of the scanning process, its bean name is
|
||||
generated by the `BeanNameGenerator` strategy known to that scanner.
|
||||
generated by the `BeanNameGenerator` strategy known to that scanner. By default, any
|
||||
Spring stereotype annotation (`@Component`, `@Repository`, `@Service`, and
|
||||
`@Controller`) that contains a name `value` thereby provides that name to the
|
||||
corresponding bean definition.
|
||||
|
||||
By default, the `AnnotationBeanNameGenerator` is used. For Spring
|
||||
xref:core/beans/classpath-scanning.adoc#beans-stereotype-annotations[stereotype annotations],
|
||||
if you supply a name via the annotation's `value` attribute that name will be used as
|
||||
the name in the corresponding bean definition. This convention also applies when the
|
||||
following JSR-250 and JSR-330 annotations are used instead of Spring stereotype
|
||||
annotations: `@jakarta.annotation.ManagedBean`, `@javax.annotation.ManagedBean`,
|
||||
`@jakarta.inject.Named`, and `@javax.inject.Named`.
|
||||
|
||||
As of Spring Framework 6.1, the name of the annotation attribute that is used to specify
|
||||
the bean name is no longer required to be `value`. Custom stereotype annotations can
|
||||
declare an attribute with a different name (such as `name`) and annotate that attribute
|
||||
with `@AliasFor(annotation = Component.class, attribute = "value")`. See the source code
|
||||
declaration of `ControllerAdvice#name()` for a concrete example.
|
||||
|
||||
[WARNING]
|
||||
====
|
||||
As of Spring Framework 6.1, support for convention-based stereotype names is deprecated
|
||||
and will be removed in a future version of the framework. Consequently, custom stereotype
|
||||
annotations must use `@AliasFor` to declare an explicit alias for the `value` attribute
|
||||
in `@Component`. See the source code declaration of `Repository#value()` and
|
||||
`ControllerAdvice#name()` for concrete examples.
|
||||
====
|
||||
|
||||
If an explicit bean name cannot be derived from such an annotation or for any other
|
||||
detected component (such as those discovered by custom filters), the default bean name
|
||||
generator returns the uncapitalized non-qualified class name. For example, if the
|
||||
following component classes were detected, the names would be `myMovieLister` and
|
||||
`movieFinderImpl`.
|
||||
If such an annotation contains no name `value` or for any other detected component
|

|
||||
== Generating an Index of Candidate Components
|
||||
|
||||
While classpath scanning is very fast, it is possible to improve the startup performance
|
||||
of large applications by creating a static list of candidates at compilation time. In this
|
||||
mode, all modules that are targets of component scanning must use this mechanism.
|
||||
|
||||
NOTE: Your existing `@ComponentScan` or `<context:component-scan/>` directives must remain
|
||||
unchanged to request the context to scan candidates in certain packages. When the
|
||||
`ApplicationContext` detects such an index, it automatically uses it rather than scanning
|
||||
the classpath.
|
||||
|
||||
To generate the index, add an additional dependency to each module that contains
|
||||
components that are targets for component scan directives. The following example shows
|
||||
how to do so with Maven:

The `spring-context-indexer` artifact generates a `META-INF/spring.components` file that

NOTE: When working with this mode in your IDE, the `spring-context-indexer` must be

||||
candidate components are updated.

Notice that `ApplicationListener` is generically parameterized with the type of your custom event (`BlockedListEvent` in the preceding example).

This means that the `onApplicationEvent()` method can remain type-safe, avoiding any need for downcasting.

You can register as many event listeners as you wish, but note that, by default, event listeners receive events synchronously.

This means that the `publishEvent()` method blocks until all listeners have finished processing the event.

it operates inside the transaction context of the publisher if a transaction context is available.
