Previous to this commit, MockHttpServletRequestBuilder was not binary
compatible as its methods had moved to a parent class with a generic
argument on the return type. MockMultipartHttpServletRequestBuilder
was also not source compatible as it no longed extended from
MockHttpServletRequestBuilder.
Both these changes were introduced to allow the AssertJ support to
expose builders that implement an extra AssertJ interface, without
copying the features the builders provide.
This commit restore compatibility. For MockHttpServletRequestBuilder
we simply override all methods that returns the generic type into
the resolved type.
MockMultipartHttpServletRequestBuilder is more involved. Because we
need to extend from MockHttpServletRequestBuilder, we have no other
choice than duplicating the code. For now, the abstract builder for
multipart is only used by the AssertJ support, but we can revisit this
again in a major release.

This commit adapts code generation to "slice" the registration of bean
definitions in separate bean methods rather than a unique method for
all of them.
If the bean factory has more than a thousand bean, a method is created
for each slice of 1000 bean definitions.

This change simplifies the CacheInterceptor way of dealing with cached

The internal ArgumentsMatchInfo type seems to have once had additional
methods beyond the functionality provided by the ArgumentsMatchKind
enum; however, that is no longer the case. Consequently, there is no
need to maintain both types.
This commit therefore merges the convenience methods from
ArgumentsMatchInfo into the ArgumentsMatchKind enum and removes the
unnecessary ArgumentsMatchInfo type.
This application/javascript MIME type is deprecated.
This commit therefore changes the MIME type mapping for *.js files from
application/javascript to text/javascript in order to align with

Prior to this commit, the Spring Expression Language (SpEL) could not
invoke a varargs MethodHandle function with a primitive array
containing the variable arguments, although that is supported for a
varargs Method function. Attempting to do so resulted in the first
element of the primitive array being supplied as a single argument to
the MethodHandle, effectively ignoring any variable arguments after the
first one.
This commit addresses this by updating the
convertAllMethodHandleArguments(...) method in ReflectionHelper as
follows when the user supplies the varargs already packaged in a
primitive array.
- Regarding conversion, use the wrapper type for a primitive varargs
array, since we eventually need an Object array in order to invoke
the MethodHandle in FunctionReference#executeFunctionViaMethodHandle().
- When deciding whether to convert a single element passed as varargs,
we now check if the argument is an array that is assignable to the
varargs array type.
- When converting an array supplied as the varargs, we now convert that
array to the varargs array type instead of the varargs component type.
Note, however, that a SpEL expression cannot provide a primitive array
for an Object[] varargs target. This is due to the fact that the
ArrayToArrayConverter used by Spring's ConversionService does not
support conversion from a primitive array to Object[] -- for example,
from int[] to Object[].

The result returned by Kotlin reflective invocation of a function
returning an inline value class is wrapped, which makes sense

This commit ensures that the varargs component type for a MethodHandle

Prior to this commit, the Spring Expression Language (SpEL) could not
invoke a varargs MethodHandle function with an array containing the
variable arguments, although that is supported for a varargs Method
function. Attempting to do so resulted in the array being supplied as a
single argument to the MethodHandle.
This commit addresses this by updating the
executeFunctionViaMethodHandle(...) method in FunctionReference as
follows when the user supplies the varargs already packaged in an array.
- Creates a new array large enough to hold the non-varargs arguments
and the unpackaged varargs arguments.
- Adds the non-varargs arguments to the beginning of that array and
adds the unpackaged varargs arguments to the end of that array.
- Invokes the MethodHandle with the new arguments array.

This commit improves SimpleInstantiationStrategy by providing a common
template method before the regular runtime and AOT. As a result, the
method to set the currently invoked factory method is deprecated as it
should no longer be used.
Closes gh-33192
Previous to this change, the transactional aspect would supersed the
user-defined AspectJ aspect, shortcircuiting to calling the original

for AOP has been introduced in c8169e5c.

Prior to this commit, the Spring Expression Language (SpEL) could not
invoke a varargs MethodHandle function with zero variable arguments,
even though the variable arguments are not required. Attempting to do
so resulted in a SpelEvaluationException with an
INCORRECT_NUMBER_OF_ARGUMENTS_TO_FUNCTION message.
This commit addresses this by updating the
executeFunctionViaMethodHandle(...) method in FunctionReference so that
it properly checks the required number of arguments for both varargs
and non-varargs MethodHandle invocations.
This commit also improves the error message for varargs invocations
with too few arguments. For example, if the MethodHandle requires at
least 1 argument plus a variable number of additional arguments and 0
arguments were supplied, the error message now states:
"Incorrect number of arguments for function 'myFunc': 0 supplied but function takes 1 or more"
Instead of:
"Incorrect number of arguments for function 'myFunc': 0 supplied but function takes 2"
Closes gh-33190
This commit harmonizes the invocation of a bean supplier with what
SimpleInstantiationStrategy does. Previously, the current factory method
was set to `null` once the invocation completes. This did not take
into account recursive scenarios where an instance supplier triggers
another instance supplier.
For consistency, the thread local is removed now if we attempt to set
the current method to null. SimpleInstantiationStrategy itself uses
the shortcut to align the code as much as possible.
Closes gh-33180
Prior to this commit, the Spring Expression Language (SpEL) incorrectly
split single String arguments by comma for Object... varargs method and

This commit addresses this by checking if the single argument type is

to the varargs component type.

FunctionReference in the Spring Expression Language (SpEL) currently
does not unwrap an InvocationTargetException; however,
ConstructorReference and MethodReference do.
For example, currently one may encounter an exception like the
following, where the 'null' comes from the fact that an
InvocationTargetException doesn't always have a message.
SpelEvaluationException: EL1023E: A problem occurred whilst attempting
to invoke the function 'formatObjectVarargs': 'null'
To address that, and to align with the behavior of ConstructorReference
and MethodReference, this commit modifies FunctionReference so that it
unwraps the InvocationTargetException to use its cause for the
exception message, resulting in an exception message like the following.
SpelEvaluationException: EL1023E: A problem occurred whilst attempting
to invoke the function 'formatObjectVarargs': 'Format specifier '%s''

This commit allows `@Reflective` to be used on arbitrary types, not
only Spring beans. This makes the feature much more powerful as
components can be tagged directly.
Scanning happens during AOT processing (typically at build-time) when
`@ReflectiveScan` is used. Types do not need to have a particular
annotation, and types that can't be loaded are ignored.
This commit also exposes the infrastructure that does the scanning so
that custom code can do the scanning in an AOT contribution if they
don't want to rely on the annotation.

Commit 84714fbae9 introduced usage of the
-Djava.locale.providers=COMPAT command-line argument for javac in order
to allow our JDK 20 builds to pass by using legacy locale data.
That was done to ensure that Date/Time formats using AM/PM produced a
standard space (" ") before the "AM" or "PM" instead of a narrow
non-breaking space (NNBSP "\u202F"), which was introduced in Java 20
due to adoption of Unicode Common Locale Data Repository (CLDR-14032).
This commit removes usage of the -Djava.locale.providers=COMPAT
command-line argument and updates all affected tests to:
- Use an NNBSP before "AM" or "PM" in input text when running on Java 20
or higher.
- Leniently match against any Unicode space character in formatted
values containing "AM" or "PM".

When a response fails to be completely emitted by the remote (connection
termination during the transmission of the response for example), a
WebClientResponseException can be propagated with a confusing message
which mainly reflects the status code and reason phrase, leading to
messages like "200 OK" in such an exception.
This change improves the situation by appending a hint at the underlying
cause whenever getMessage() is called on a WebClientResponseException
which was created with a non-error status code.

This commit introduces an abstraction that allows to convert HTTP
inputs to a data type based on a set of HttpMessageConverter.
Previously, the AssertJ integration was finding the first converter
that is able to convert JSON to a Map (and vice-versa) and used that
in its API. With the introduction of SmartHttpMessageConverter, exposing
a specific converter is fragile.
The added abstraction allows for converting other kind of input than
JSON if we need to do that in the future.
Closes gh-33148
Prior to this commit, paths configured via the scripts attribute in
@Sql were required to be final paths without dynamic placeholders;
however, being able to make script paths dependent on the current

@Sql script paths which will be replaced by properties available in
the Environment of the test's ApplicationContext.

SmartHttpMessageConverter is similar to GenericHttpMessageConverter,

- No contextClass parameter
- `@Nullable Map<String, Object> hints` additional parameter for write
and read methods
This commit also refines RestTemplate#canReadResponse in order to use
the most specific converter contract when possible.

Prior to this commit, the fix for gh-32730 disabled the involvment of
the osbervation filter for async dispatches. Instead of relying on ASYNC
dispatches to close the observation for async requests, this is now
using an async listener instead: async dispatches are not guaranteed to
happen once the async request is handled.
This change caused another side-effect: because async dispatches are not
considered anymore by this filter, the observation scope is not
reinstated for async dispatches. For example, `ResponseBodyAdvice`
implementations do not have the observation scope opened during their
execution.
This commit re-enables async dispatches for this filter, but ensures
that observations are not closed during such dispatches as this will be
done by the async listener.

Prior to this commit, @TestBean factory methods had to be defined in
the test class, one of its superclasses, or in an implemented

name.
To address that, this commit introduces support for referencing a
@TestBean factory method via its fully-qualified method name following
the syntax <fully-qualified class name>#<method name>.

Prior to this commit, if ModelMap was used as an argument type in a
WebFlux controller method, the user encountered an exception similar to
the following.

Controller [example.SampleController]
Method [java.lang.String example.SampleController.index(org.springframework.ui.ModelMap)] with argument values:

However, the above error message is a bit cryptic since the error
occurs while attempting to invoke the controller method with an
instance of BindingAwareConcurrentModel which is not compatible with
ModelMap. More importantly, this error message does not explicitly
convey to the user that a ModelMap is not supported.
This commit improve the diagnostics for the user in such scenarios by
rejecting the use of ModelMap upfront in WebFlux.
Consequently, for the same use case as above, the user now encounters
an exception similar to the following.
java.lang.IllegalStateException:

java.lang.String example.SampleController.index(org.springframework.ui.ModelMap):

Prior to this commit, the "Method Arguments" documentation for WebFlux

This commit updates the documentation to reflect this.
In addition, this commit updates related Javadoc and tests to avoid

Prior to this commit, RequestMappingViewResolutionIntegrationTests
invoked the following:
configurer.setTemplateLoaderPath(
"classpath*:org/springframework/web/reactive/view/freemarker/");
However, that configuration is invalid since `classpath*:` is not
supported for a `templateLoaderPath`.
Despite that, the tests still passed since FreeMarkerConfigurer already
registers a new ClassTemplateLoader(FreeMarkerConfigurer.class, ""),
which automatically finds template files in the same package as
FreeMarkerConfigurer (for the "spring.ftl" macro library support) and
coincidentally RequestMappingViewResolutionIntegrationTests as well
(which resides in the same package).
This commit therefore removes the invalid configuration and adds a
comment to explain what's going on.

This commit aligns code generation to recent improvement in the core
container regarding type detection. Now that nested types are properly
resolved, our code generation that uses hasResolvableGenerics() is
taking the wrong decision if only a nested type has an unresolved
generics. Previously, this was hidden by the fact that the core
container would not resolve them recursively.
A new hasResolvableGenerics() method allows to verify that at least
one direct generic type is resolved. This restore our intent of checking
at the first level only and let recursive invocations figure out if they
have to write the raw type or the type with generics.

Prior to this commit, the isClientDisconnectedException() method in
DisconnectedClientHelper checked whether the message of the ultimate

the exception message contained "Connection reset", which is the case
for the SocketException thrown by throwConnectionReset() in

This commit therefore replaces the "connection reset by peer" phrase
with "connection reset" in order to support all exception messages

Prior to this commit, WebFlux had Protobuf codecs for managing the
`Message`/`"application/x-protobuf"` encoding and decoding.
The `com.google.protobuf:protobuf-java-util` library has additional
support for JSON (de)serialization, but this is not supported by
existing codecs.
This commit adds the new `ProtobufJsonEncode` and `ProtobufJsonDecoder`
classes that support this use case. Note, the `ProtobufJsonDecoder` has
a significant limitation: it cannot decode JSON arrays as
`Flux<Message>` because there is no available non-blocking parser able
to tokenize JSON arrays into streams of `Databuffer`. Instead,
applications should decode to `Mono<List<Message>>` which causes
additional buffering but is properly supported.
Closes gh-25457
This commit improves the handling of asynchronous requests by offering
a way to opt-in for the raw async result. This provides first class
support for asserting a request that might still be in process as well
as the asyncResult, if necessary.
See gh-33040
This commit makes asynchronous requests first class by providing a
MvcTestResult that represents the final, completed, state of a request
by default. Previously, the result was an intermediate step that may
require an ASYNC dispatch to be fully usable. Now it is de facto
immutable.
To make things a bit more explicit, an `.exchange(Duration)` method has
been added to provide a dedicated time to wait. The default applies a
default timeout that is consistent with what MVcResult#getAsyncResult
does.
Given that we apply the ASYNC dispatch automatically, the intermediate
response is no longer available by default. As a result, the asyncResult
is not available for assertions.
As always, it is possible to use plain MockMvc by using the `perform`
method that takes the regular RequestBuilder as an input. When this
method is invoked, no asynchronous handling is done.

This commit replaces the use of EngineTestKit to test scenarios where
bean override could not process the test class. There is no need to
run an actual test for this as:
1. Regular integration tests are already validating that adding the
annotation triggers the processing as part of executing the test.
2. The entry point is a ContextCustomizer that can easily be invoked
in a regular test.
As part of harmonizing this, AbstractTestBeanIntegrationTestCase can
be nested, and BeanOverrideTestSuite serve no purpose. The tests can
be executed in an IDE without any special setup.
This commit harmonizes the class names of the bean override support by
using a consistent prefix for integration test, inspire from the one
that was used in Spring Boot
This commit revers the removal of the `private` keyword in the examples
of the reference documentation and the tests for consistency. While the
default visibility makes the example more concise, it could imply to the
reader that the field (or the factory method) cannot be private.
Also, there is no need to multiply anything returned from `Objects.hash`
as its very distinct on its own already.
This commit adds new information about the execution and scheduling of

This commit harmonizes how a candidate bean definition is determined

will be picked up transparently, the same it is done for regular
autowiring.
This commit also reviews the documentation of the feature as considering
the field means that its name is taken into account to compute a cache
key if by-type lookup is requested.

This commit fixes a package tangle between the root bean override
package and its sub-packages. This was vastly improved with the
introduction of `@DummyBean` but we still had a few tests that were
at the wrong place.
This commit changes how factory method for `@TestBean` usage is
discovered. Previously the field name or bean name suffixed with
'TestOverride' was used. It sounds more natural to just use the
field name or bean name, leaving cases where a suffix is required
to explicitly providing the method name.
As part of this change, the exception messages have been revisited as
it's less since the method name candidates have the exact same name
as the field or bean name. A `()` is added to make it more clear the
name is for a method.
Closes gh-32940
TestOverrideMetadata was doing byName lookup by default, even without
a bean name. This makes writing tests that need to do by type lookup

and doesn't override anything from it to make sure the behavior is not
altered.

By swallowing the exception on failing to release a savepoint, we are hiding
client code from database errors that they may need to be aware of or handle.
e.g. if the connection is now dead when trying to release the savepoint, by
swallowing the exception here, client code has no way of knowing this now until
the next operation on the database, which will yield a confusing message about
the problem and obscures where the failure occurred as it will be in a different
part of their code that throws any exception.
Swallowing the exception here is also inconsistent with all the other database
calls in the Transaction Object, where we always raise an exception up and let
client code decide how to handle the error.
Prior to this commit, the `ServerHttpObservationFilter` would support
async dispatches and would do the following:
1. start the observation
2. call the filter chain
3. if async has started, do nothing
4. if not in async mode, stop the observation
This behavior would effectively rely on Async implementations to
complete and dispatch the request back to the container for an async
dispatch. This is what Spring web frameworks do and guarantee.
Some implementations complete the async request but do not dispatch
back; as a result, observations could leak as they are never stopped.
This commit changes the support of async requests. The filter now
opts-out of async dispatches - the filter will not be called for those
anymore. Instead, if the application started async mode during the
initial container dispatch, the filter will register an AsyncListener to
be notified of the outcome of the async handling.
Fixes gh-32730
This commit reviews how bean override support can influence the key of
an application context cached by the TCF. OverrideMetadata and its
subclasses now implement a proper equals/hashCode pair that is tested
in various scenarios.
Due to how the TCF operates, OverrideMetadata has to be computed in
two locations:
1. In a ContextCustomizerFactory, using the metadata in the enclosing
class if any. This determines whether a customizer is needed in the
first place. The computed set of unique metadata identifies the
customizer and participates in the application context cache's key.
2. In the TestExecutionListener so that it knows the override points
it has to process.
Parsing of the metadata based on a test class has been greatly
simplified and moved to OverrideMetadata proper as we don't need several
flavors. 1 and 2 are using the same algorithm with the former wrapping
that in a Set to compute a proper key.
BeanOverrideContextCustomizerEqualityTests provides a framework for
testing edge cases as we only care about whether the created
ContextCustomizer behaves correctly against the identity of another.
Closes gh-32884
This commit reviews the structure of several classes to comply with
our guidelines. Also, rather than exposing a static method to configure
the context in a test, we call the high-level API directly.
Rather than having to override the getBeanName method when there is one,
this commit moves it as a @Nullable argument. This makes sure that
equals and hashCode consistently use the bean name. getBeanName cannot
be final just yet as the test infrastructure overrides it.
Also, arguments are now ordered consistently, which improves code

Prior to this commit, exceptions thrown by MVC functional handlers would
not be considered by `ExceptionHandlerExceptionResolver`. This means
that common exceptions would not be handled consistently between
annotated and functional handlers. This is true, for example, for all
`ProblemDetails`-related exception handling.
While MVC functional and annotation models are separate concepts,
WebFlux has a different error handling model that processes all
exceptions in a central place.
This commit ensures that `ExceptionHandlerExceptionResolver` considers
exceptions thrown by handlers of type `HandlerFunction<?>` and processes
them accordingly.

This commit aligns Spring WebFlux with WebMvc in adding URI variables

I accidentally introduced a regression in commit d185bb1d97 by no
longer checking the number of unique method names found when searching
for @TestBean factory methods.
This commit reintroduces that check and introduces a proper unit test
in TestBeanOverrideProcessorTests.
It turns out that we already had an integration test that was intended
to check for this scenario; however, that test actually did not test
this scenario due to a copy-and-paste error. Thus, this commit also
updates TestBeanInheritanceIntegrationTests so that
fieldInSupertypeWithPrioritizedFactoryMethodInSubtype() tests what it's
supposed to.
This commit benefits from a feature introduced in AssertJ 3.26.0, see
https://github.com/assertj/assertj/pull/3377.
This allows to use any AssertFactory and convert the actual value to
the type the factory manages. Previously, we were using
ParameterizedTypeReference to express the type with its generic
signature but the returned assert object would not be narrowed to the
converted type.
Thanks to this change, we can request to convert the actual value to
`InstanceOfAssertFactories.list(Member.class)` and get a `ListAssert`
of `Member` as a result, rather than an `ObjectAssert` of `List<User>`.
Thanks very much to @scordio for his efforts.

- Use idiomatic EngineTestKit APIs to simplify assertions on
EngineTestKit results.
- Introduce BeanOverrideTestSuite to simplify running all bean override
tests within the IDE.
- Separate failure and success scenario tests, so that failure tests do
not launch the JUnit Platform to run tests using the Spring
TestContext Framework (TCF) within a test class that itself uses the
TCF.
- Make AbstractTestBeanIntegrationTestCase actually abstract.
- Rename test case classes to give them meaningful names and simplify

This commit moves the features of MockHttpServletRequestBuilder in
an abstract class so that another class can offer the same feature

This change benefits MockMultipartHttpServletRequestBuilder that can

and deprecates the former `String` variants. This will allow
observability libraries like Micrometer to expose this as metrics:
```

This commit uses the bean factory `isAutowiredCandidate` method directly
in `BeanOverrideBeanFactoryPostProcessor` to select a single match among
multiple candidates when matching by type.
The expected consequence, in most cases, is that this will delegate to
a `@Qualifier`-aware `QualifierAnnotationAutowireCandidateResolver`.
In that sense, bean overriding by-type matching is now potentially
taking Qualifier annotations or meta-annotations into account.
It also changes the way existing bean definitions are checked in case
a bean name has been specified: factory beans are now taken into account
when checking the type of an existing definition matches the expected
bean override type.

Prior to this commit, `@ExceptionHandler` annotated controller methods
could be mapped using the exception type declaration as an annotation
attribute, or as a method parameter.
While such methods support a wide variety of method arguments and return

different methods (in the same controller/controller advice).
This commit adds a new `produces` attribute on `@ExceptionHandler`; with
that, applications can vary the HTTP response depending on the exception
type and the requested content-type by the client:
```
@ExceptionHandler(produces = "application/json")
public ResponseEntity<ErrorMessage> handleJson(IllegalArgumentException exc) {
return ResponseEntity.badRequest().body(new ErrorMessage(exc.getMessage(), 42));
}
@ExceptionHandler(produces = "text/html")

return "errorView";

The code was necessary while ForwardedHeaderFilter was deprecated
but still possible to use. When the filter was removed, this code
could have been removed as well.
Prior to this commit, DynamicPropertyRegistry could only be used with a
static @DynamicPropertySource method in an integration test class;
however, it can also be useful to be able to register a "dynamic
property" from within a test's ApplicationContext -- for example, in a
@Bean method in a @Configuration class that is specific to testing
scenarios.
To support such use cases, this commit updates the dynamic property
source infrastructure so that a DynamicPropertyRegistry is always
registered as a singleton bean in a test's ApplicationContext. This
allows DynamicPropertyRegistry to be autowired into a @Configuration
class or supplied to a @Bean method as an argument as shown in the
following example.
@Bean
@DynamicPropertySource
ApiServer apiServer(DynamicPropertyRegistry registry) {
ApiServer apiServer = new ApiServer();
registry.add("api.url", apiServer::getUrl);
return apiServer;
}
Note that the use of @DynamicPropertySource on the @Bean method is
optional and results in the corresponding bean being eagerly
initialized so that other singleton beans in the context can be given
access to the dynamic properties sourced from that bean when those
other beans are initialized.
Side note: DynamicPropertySourceBeanInitializer temporarily implements
LoadTimeWeaverAware since doing so is currently the only way to have a
component eagerly initialized before the
ConfigurableListableBeanFactory.preInstantiateSingletons() phase.
However, we plan to introduce a first-class callback to support such
use cases in the future.

This commit introduces a `isNotEqualTo(String)` assertion in order to
avoid false negatives when using the default Object-based assertion.
This is a risk since MediaTypeAssert has a `isEqualTo(String)` method

and expect the same parsing behaviour.
This commit also adds tests around the String parsing and the isNotEqual
cases.

Prior to this commit, the `ReactiveTypeHandler` would handle `Flux`-like
return types from controller methods and adapt them to SSE streams using
the `SseEmitter`/`ResponseBodyEmitter` APIs. In case an `IOException` is
thrown while writing to the HTTP response stream, the
`ReactiveTypeHandler` would rely on the Servlet container to call
`AsyncListener#onError` - this would be the signal for Spring MVC to
complete the async exchange. To prevent racing issues between this
signal and the actual handling of the exception, changes like gh-20173
were applied. Since then, robust checks were added with gh-32340 in
`StandardServletAsyncWebRequest.LifecycleHttpServletResponse`.
With Jetty 12, `AsyncListener#onError` would not be called as the error
would happen while writing in blocking mode to the response (so, not
using the Servlet WriteListener contract). But still, such `IOException`
would still result in the closing of the HTTP connection. As of Jetty
12.0.4, this is no longer the case and the party managing the async
lifecycle is in charge of completing the exchange, as it should. This
means that the current behavior leaks HTTP connections for these cases
and causes memory issues.
This commit ensures that such exceptions happening during response
writes are caught and result in the completion of the `SSEEmitter` and
the closing of the exchange. Even if other Servlet containers still
propagate the error `AsyncListener#onError`, competing signals are still
managed with gh-32340.
Closes gh-32629
Prior to this commit, `DataBufferLimitException` would be thrown by

result in an HTTP 413 "Payload too large" response status.

This commit renames AssertableMockMvc to MockMvcTester as the former
was too mouthful, and we are looking for a naming pattern that can be
applied consistently to test utilities that rely on AssertJ.
Rather than AssertableMvcResult, we now use MvcTestResult and it no
longer extends from MvcResult itself. That avoids having existing code
that is migrated to the new API whilst assigning the result to MvcResult
and get a bad DevXP as that doesn't bring any of the AssertJ support.

A bug has existed in Spring's MergedAnnotations support since it was
introduced in Spring Framework 5.2. Specifically, if the
MergedAnnotations API is used to search for annotations with "standard
repeatable annotation" support enabled (which is the default), it's
possible to search for a repeatable annotation but not for the
repeatable annotation's container annotation.
The reason is that MergedAnnotationFinder.process(Object, int, Object,
Annotation) does not process the container annotation and instead only
processes the "contained" annotations, which prevents a container
annotation from being included in search results.
In #29685, we fixed a bug that prevented the MergedAnnotations support
from recognizing an annotation as a container if the container
annotation declares attributes other than the required `value`
attribute. As a consequence of that bug fix, since Spring Framework
5.3.25, the MergedAnnotations infrastructure considers such an
annotation a container, and due to the aforementioned bug the container
is no longer processed, which results in a regression in behavior for
annotation searches for such a container annotation.
This commit addresses the original bug as well as the regression by
processing container annotations in addition to the contained
repeatable annotations.

Prior to this commit, HTTP requests sent with the
`HttpComponentsClientHttpRequestFactory` would not set a
"Content-Length" header for empty request bodies. Setting a request

align the behavior with other HTTP clients.
Developers would often rely on `BufferingClientHttpRequestFactory` to
set this information on the request.
This commit ensures that a `NullEntity` is used for unsafe HTTP methods,
when no body has been set for the request. This result in a
"Content-Length:0" request header.

This commit improves on the bean overriding feature in several ways:
the API is simplified and polished (metadata and processor contracts,
etc...).
The commit also reworks infrastructure classes (context customizer,
test execution listener, BeanOverrideBeanFactoryPostProcessor, etc...).
Parsing of annotations is now fully stateless.
In order to avoid OverrideMetadata in bean definition and to make a
first step towards AOT support, the BeanOverrideBeanFactoryPostProcessor
now delegates to a BeanOverrideRegistrar to track classes to parse,
the metadata-related state as well as for the field injection methods
for tests.
Lastly, this commit increases the test coverage for the provided
annotations and adds integration tests and fixes a few `@TestBean`
issues.
Prior to this commit, `BufferingClientHttpRequestWrapper` would always
write to the actual client request body, even if the buffered content
was empty (empty byte array).
This would cause issues with specific client request factories,
especially the OkHttp variant, that would consider empty byte arrays as
non-empty body and would reject such cases for GET requests with an
"IllegalArgumentException: method GET must not have a request body".
This commit only writes to the request if the buffered content is not
empty.

This set of commits introduces a new IndexAccessor SPI for the Spring
Expression Language (SpEL) which allows third parties to customize the
SpEL Indexer.
A custom IndexAccessor implementation can be registered in a
StandardEvaluationContext.
For an example, see the JacksonArrayNodeIndexAccessor in IndexingTests
in the spring-expression module.
See gh-26409
Closes gh-26478
Prior to this commit, the read() method in the IndexAccessor SPI
declared a return type of ValueRef which introduced a package cycle.
This commit addresses this by aligning with the PropertyAccess SPI and
returning TypedValue from IndexAccessor's read() method. This commit
also reworks the internals of Indexer based on a new, local
IndexAccessorValueRef implementation.

Prior to this commit, MethodIntrospector failed to properly detect
bridge methods for subsequent invocations of selectMethods() with the
same targetType and MetadataLookup, if such subsequent invocations
occurred after the ApplicationContext had been refreshed.
The reason this occurs is due to the following.
- Class#getDeclaredMethods() always returns "child copies" of the
underlying Method instances -- which means that `equals()` should be
used instead of `==` whenever the compared Method instances can come
from different sources (such as the static caches mentioned below).
- BridgeMethodResolver caches resolved bridge methods in a static cache
-- which is never cleared.
- ReflectionUtils caches declared methods in a static cache
-- which gets cleared when an ApplicationContext is refreshed.
Consequently, if you attempt to load an ApplicationContext twice in the
same ClassLoader, the second attempt uses the existing, populated cache
for bridged methods but a cleared, empty cache for declared methods.
This results in new invocations of Class#getDeclaredMethods(), and
identity checks with `==` then fail to detect equivalent bridge methods.
This commit addresses this by additionally comparing bridge methods
using `equals()` in MethodIntrospector.selectMethods().
Note that the `==` checks remain in place as an optimization for when
`equals()` is unnecessary.
Closes gh-32586
Prior to this commit, the `JmsTemplate#sendAndReceive` method would not
instrument the JMS session. This means that no metric would be recorded
when sending the message and no trace would be propagated downstream.
This commit ensures that the JMS session is instrumented in this case as
well. Note, the reception of the response message does not create a
`"jms.message.process"` observation as the session is only receiving the
message, no listener has been configured on the message consumer.

This commit makes the use of bean definition overriding more visible and
prepare for a deprecation of the feature in the next major release.
As of this commit, use of bean definition overriding logs at INFO level.
The previous log level can be restored by setting the
allowBeanDefinitionOverriding flag explicitly on the BeanFactory (or
via the related ApplicationContext).
A number of tests that are using bean overriding on purpose have been
updated to set this flag, which will make them easier to find once we
actually deprecate the feature.

This set of commits introduces support for a null-safe operator in the
Spring Expression Language (SpEL), including support for compiling

Prior to this commit, MethodReference and PropertyOrFieldReference
already defined local isNullSafe() methods, but we need identical

introduces an isNullSafe() method in SpelNodeImpl with a default
implementation that returns false.

Prior to this commit when a required parameter defined as a property or

Prior to this commit, the SpEL compiler generated classes in a package
named "spel" with names following the pattern "Ex#", where # was an
index starting with 2.
This resulted in class names such as:
- spel.Ex2
- spel.Ex3
This commit improves the names of classes created by the SpEL compiler
by generating classes in a package named
"org.springframework.expression.spel.generated" with names following
the pattern "CompiledExpression#####", where ##### is a 0-padded
counter starting with 00001.
This results in class names such as:
- org.springframework.expression.spel.generated.CompiledExpression00001
- org.springframework.expression.spel.generated.CompiledExpression00002
This commit also moves the saveGeneratedClassFile() method from
SpelCompilationCoverageTests to SpelCompiler and enhances it to:
- Save classes in a "build/generated-classes" directory.
- Convert package names to directories.
- Create missing parent directories.
- Use logging instead of System.out.println().
Running a test with saveGeneratedClassFile() enabled now logs something
similar to the following.

The ApplicationContext has a resource cache that it uses while the
context is being refreshed. Once the refresh phase completes, the
cache is cleared as its content is no longer in use. If beans are
lazily initialized, there is a case where the cache might be filled
again as processing is deferred past the refresh phase.
For those cases, the cache is not cleared. This can be a problem when
running in this mode with a large set of test configurations as the TCF
caches the related contexts.
This commit includes an additional TestExecutionListener to the TCF that
clears the resource cache if necessary once a test class completes. It
is ordered so that it runs after `@DirtiesContext` support as marking
the context as dirty will remove it from the cache and make that extra
step unnecessary.

This commit introduces null-safety checks for spring-core at build-time
in order to validate the consistency of Spring null-safety annotations
and generate errors when inconsistencies are detected during a build
(similar to what is done with Checkstyle).
In order to make that possible, this commit also introduces a new
org.springframework.lang.Contract annotation inspired from
org.jetbrains.annotations.Contract, which allows to specify semantics
of methods like Assert#notNull in order to prevent artificial
additional null checks in Spring Framework code base.
This commit only checks org.springframework.core package, follow-up
commits will also extend the analysis to other modules, after related
null-safety refinements.

The fix for #31254 resulted in an InvalidMimeTypeException being thrown
by MimeTypeUtils.sortBySpecificity() instead of an
IllegalArgumentException. However, InvalidMimeTypeException extends
IllegalArgumentException. Consequently, the change from
IllegalArgumentException to InvalidMimeTypeException did not result in
the desired effect in HeaderContentNegotiationStrategy.
HeaderContentNegotiationStrategy.resolveMediaTypes() still allows the
InvalidMimeTypeException to propagate as-is without wrapping it in an
HttpMediaTypeNotAcceptableException.
To address this issue, this commit catches InvalidMediaTypeException
and InvalidMimeTypeException in HeaderContentNegotiationStrategy and
wraps the exception in an HttpMediaTypeNotAcceptableException.

This commit adds a new way to use MockMvc by returning a MvcResult that
is AssertJ compatible. Compared to the existing MockMvc infrastructure,
this new model has the following advantages:
* Can be created from a MockMvc instance
* Dedicated builder methods for easier setup
* Assertions use familiar AssertJ syntax with discoverable assertions
through a DSL
* Improved exception message
See gh-21178
Co-authored-by: Brian Clozel <brian.clozel@broadcom.com>
This commit adds AssertJ compatible assertions for HTTP request and
responses, including headers, media type, and response body. The latter
delegate to the recently included JSON assert support.

Historically, we have rarely intentionally thrown a
NullPointerException in the Spring Framework. Instead, we prefer to
throw either an IllegalArgumentException or IllegalStateException
instead of a NullPointerException.
However, changes to the code in recent times have introduced the use of
Objects.requireNonNull(Object) which throws a NullPointerException
without an explicit error message.
The latter ends up providing less context than a NullPointerException
thrown by the JVM (since Java 14) due to actually de-referencing a
null-pointer. See https://openjdk.org/jeps/358.
In light of that, this commit revises our current use of
Objects.requireNonNull(Object) by removing it or replacing it with
Assert.notNull().
However, we still use Objects.requireNonNull(T, String) in a few places
where we are required to throw a NullPointerException in order to
comply with a third-party contract such as Reactive Streams.
Closes gh-32430
Prior to this commit, gh-21783 introduced `ReadOnlyHttpHeaders` to avoid
parsing media types multiple times during the lifetime of an HTTP
exchange: such values are cached and the headers map is made read-only.
This also added a new `HttpHeaders.writableHttpHeaders` method to unwrap
the read-only variant when needed.
It turns out this method sends the wrong signal to the community
because:
* the underlying map might be unmodifiable even if this is not an
instance of ReadOnlyHttpHeaders
* developers were assuming that modifying the collection that backs the
read-only instance would work around the cached values for
Content-Type and Accept headers
This commit adds more documentation to highlight the desired behavior
for cached values by the read-only variant, and deprecates the
`writableHttpHeaders` method as `ReadOnlyHttpHeaders` is package private
and we should not surface that concept anyway.
Instead, this commit unwraps the read-only variant if needed when a new
HttpHeaders instance is created.

Prior to this commit, gh-31609 added the current observation context as
a request attribute for `WebClient` calls. While it was not confirmed as
the main cause, this feature was linked to several reports of memory
leaks. This would indeed attach more memory to the request object graph
at runtime - although it shouldn't prevent its collection by the GC.
This commit removes this feature and instead developers should get the
current observation from the reactor context if they wish to interact
with it.

This commit introduce a change of behaviour when component scan is used
with conditions. Previously, any condition in the REGISTER_BEAN phase
were ignored and the scan was applied regardless of the outcome of

Rather than ignoring those conditions, this commit fails fast when it
detects such use case. Code will have to be adapted accordingly.

Commit c79436f832 ensured that methods are invoked via a public
interface or public superclass when compiling Spring Expression
Language (SpEL) expressions involving method references or property
access (see MethodReference, PropertyOrFieldReference, and
collaborating support classes). However, compilation of expressions
that access properties by indexing into an object by property name is
still not properly supported in all scenarios.
To address those remaining use cases, this commit ensures that methods
are invoked via a public interface or public superclass when accessing
a property by indexing into an object by the property name – for
example, `person['name']` instead of `person.name`.
In addition, SpEL's Indexer now properly relies on the
CompilablePropertyAccessor abstraction instead of hard-coding support
for only OptimalPropertyAccessor. This greatly reduces the complexity
of the Indexer and simultaneously allows the Indexer to potentially
support other CompilablePropertyAccessor implementations.

This commit introduces two sets of annotations (`@TestBean` on one side

a BeanOverrideProcessor implementation and an OverrideMetadata subclass.

Prior to this commit, error signals flowing from the client response
publisher in `WebClient` would be set on the `Observation.Context`. This

this issue.

Although the Spring Expression Language (SpEL) generally does a good
job of locating the public declaring class or interface on which to

are invoked via a public interface or public superclass whenever
possible when compiling SpEL expressions.

This commit fixes an issue where a Cacheable method which returns a
Flux (or multi-value publisher) will be invoked once, but the returned
publisher is actually subscribed twice.
The previous fix 988f3630c would cause the cached elements to depend on
the first usage pattern / request pattern, which is likely to be too
confusing to users. This fix reintroduces the notion of exhausting the
original Flux by having a second subscriber dedicated to that, but uses
`refCount(2)` to ensure that the original `Flux` returned by the cached
method is still only subscribed once.

This commit fixes an issue where a Cacheable method which returns a
Flux (or multi-value publisher) will be invoked once, but the returned
publisher is actually subscribed twice.
By using the Reactor `tap` operator, we ensure that we can emit values
downstream AND accumulate emitted values into the List with a single
subscription.
The SignalListener additionally handles scenarios involving cancel,
for instance in case of a `take(1)` in the chain. In that case values
emitted up until that point will have been stored into the List buffer,
so we can still put it in the cache. In case of error, no caching occurs
and the internal buffer is cleared. This implementation also protects
against competing onComplete/onError signals and cancel signals.

Prior to this commit, if a Spring Expression Language (SpEL) expression
referenced the root context object via the #root or #this variable, we
inserted a checkcast in the generated byte code that cast the object to
its concrete type. However if the root context object's type was
non-public, that resulted in an IllegalAccessError when the compiled
byte code was executed.
VariableReference.getValueInternal() already contains a solution for
global variables which inserts a checkcast to Object in the generated
byte code instead of to the object's concrete non-public type.
This commit therefore applies the same logic to #root (or #this when
used to reference the root context object) that is already applied to
global variables.

Based on feedback from several members of the community, we have

introduced in ContentCachingResponseWrapper in 375e0e6827.
This commit therefore completely removes Content-Type caching in
ContentCachingResponseWrapper and updates the existing tests
accordingly.
To provide guards against future regressions in this area, this commit
also introduces explicit tests for the 6 ways to set the content length

Commit 375e0e6827 introduced a regression in
ContentCachingResponseWrapper (CCRW). Specifically, CCRW no longer
honors Content-Type and Content-Length headers that have been set on
the wrapped response and returns null for those header values if they
have not been set directly on the CCRW.
This commit fixes this regression as follows.
- The Content-Type and Content-Length headers set in the wrapped
response are honored in getContentType(), containsHeader(),
getHeader(), and getHeaders() unless those headers have been set
directly on the CCRW.
- In copyBodyToResponse(), the Content-Type in the wrapped response is
only overridden if the Content-Type has been set directly on the CCRW.

This commit removes the previous implementation in favor of the new
PlaceholderParser. The only noticeable side effect is that the exception
is no longer an IllegalArgumentException, but rather the dedicated
PlaceholderResolutionException.
See gh-9628
This commit provides a rewrite of the parser for properties containing
potentially placeholders.
Assuming a source where `firstName` = `John` and `lastName` = `Smith`,
the "${firstName}-${lastName}" property is evaluated as "John-Smith".
Compared with the existing implementation in PropertyPlaceholderHelper,
the new implementation offers the following extra features:
1. Placeholder can be escaped using a configurable escape character.
When a placeholder is escaped it is rendered as is. This does apply to
any nested placeholder that wouldn't be escaped. For instance,
"\${firstName}" is evaluated as "${firstName}".
2. The default separator can also be escaped the same way. When the
separator is escaped, the left and right parts are not considered as
the key and the default value respectively. Rather the two parts
combined, including the separator (but not the escape separator) are
used for resolution. For instance, ${java\:comp/env/test} is looking
for a "java:comp/env/test" property.
3. Placeholders are resolved lazily. Previously, all nested placeholders
were resolved before considering if a separator was present. This
implementation only attempts the resolution of the default value if the
key does not provide a value.
4. Failure to resolve a placeholder are more rich, with a dedicated
PlaceholderResolutionException that contains the resolution chain.

Prior to this commit, the `SimpleCommandLineArgsParser` would reject
"--" arguments as invalid. As reported by the community, the POSIX
utility conventions (Guideline 10) state that
> The first -- argument that is not an option-argument should be
> accepted as a delimiter indicating the end of options.
> Any following arguments should be treated as operands, even if they
> begin with the '-' character.
This commit updates `SimpleCommandLineArgsParser` to not reject "--"
arguments and instead to consider remaining arguments as non-optional.

This commit updates the WebSocket message broker configuration to stop
setting a thread name prefix for externally defined Executors.
This used to apply to:
* clientInboundChannel with a thread name prefix of
"clientInboundChannel-".
* clientOutboundChannel with a thread name prefix of
"clientOutboundChannel-".
* brokerChannel with a thread name prefix of "brokerChannel-".
Closes gh-32132
This commit harmonizes the configuration of the WebSocket message
broker to use Executor rather than TaskExecutor as only the former
is enforced. This lets custom configuration to use a wider range

This commit improves jsonpath support in WebTestClient by detecting
a suitable json encoder/decoder that can be applied to assert more
complex data structure.
Closes gh-31653
This commit improves JsonPathExpectationsHelper to allow a custom json
path configuration to be defined. The primary objective of a custom
configuration is to specify a custom mapper that can deserialize complex
object structure.
As part of this commit, it is now possible to invoke a Matcher against
a type that holds generic information, using a regular
ParameterizedTypeReference.
Given that the existing constructor takes a vararg of Object, this
commit also deprecates this constructor in favor of formatting the
expression String upfront.

This commit allows EmbeddedDatabaseConfigurer instances to be further

Closes gh-21160
Prior to this commit, the SseBuilder API in WebMvc.fn would only allow
to send Server-Sent Events with `data:` items in them. The spec doesnn't
disallow this and other specifications rely on such patterns to signal
the completion of a stream, like:
```
event:next
data:some data
event:complete
```
This commit adds a new `send()` method without any argument that sends
the buffered content (id, event comment and retry) without data.
Fixes: gh-32270
Although EvaluationContext defines the API for setting and looking up
variables, the internals of the Spring Expression Language (SpEL)
actually provide explicit support for registering functions as
variables.
This is self-evident in the two registerFunction() variants in
StandardEvaluationContext; however, functions can also be registered as
variables when using the SimpleEvaluationContext.
Since custom functions are also viable in use cases involving the
SimpleEvaluationContext, this commit documents that functions may be
registered in a SimpleEvaluationContext via setVariable().
This commit also explicitly documents the "function as a variable"
behavior in the class-level Javadoc for both StandardEvaluationContext
and SimpleEvaluationContext, as well as in the reference manual.

The cancellation of read and write inactivity tasks was done via
WebSocketHandler#afterConnectionClosed, relying on the WebSocket
library to always invoke the callback.
This change moves the cancellation to the `close` method instead
that in turn is called from DefaultStompSession#resetConnection,
in effect making the cancellation more proactive and aligned with
connection cleanup in DefaultStompSession vs relying on a
subsequent call from the WebSocket library after the connection
is closed.
Closes gh-32195
ConnectionLostException was applies only after the WebSocket library
notified us of a session close. However, read inactivity and heartbeat
send failures are also cases of the connection being lost rather than
closed intentionally.
This commit also ensures resetConnection is called after a heartbeat
write failure, consistent with other places where a transport error
is handled that implies the connection is lost.

Fix another instance where a LinkedHashMap was initialized with an initial
capacity that would always cause a resize / rehash to occur. Switch to
CollectionUtils.newLinkedHashMap to size the map appropiately for the expected
number of items.
Closes gh-32215
Prior to this commit, the `RequestPredicates` would add new attributes
to the existing request attributes by creating a new `LinkedHashMap`
with the total number of elements as its new initial capacity.
This would not achieve optimal performance as initial resize or rehash
operations could be expected. Consistently using
`CollectionUtils#newLinkedHashMap` avoids this problem.
Closes gh-32201
ServletAttributesMap inherited default implementations of the size
and isEmpty methods from AbstractMap which delegates to the Set returned
by entrySet. ServletAttributesMap's entrySet method made this fairly
expensive, since it would copy the attributes to a List, then use a
Stream to build the Set. To avoid the cost, add implementations of
isEmpty / size that don't need to call entrySet at all.
Additionally, change entrySet to return a Set view that simply lazily
delegates to the underlying servlet request for iteration.
Closes gh-32189
This commit ensures that, when creating a RestClient.Builder from a
RestTemplate, the UriBuilderFactory is only copied if it has been

This commit also introduces a small memory optimization in
DefaultUriBuilderFactory, so that default environment variables are
created lazily.

As a bit of trivia, Jakarta EL was originally Unified EL, which was
originally JSP EL, which was originally SPEL.
SPEL: Simplest Possible Expression Language
SpEL: Spring Expression Language
So one could say that SPEL inspired SpEL.
This commit introduces a globally applied Checkstyle rule which
enforces the use of class literals for primitive types and void by
forbidding the use of the TYPE constants in Boolean, Character, Byte,
Short, Integer, Long, Float, Double, and Void.
For example, if MyClass uses one of the TYPE constants, the build will
now fail with a message similar to the following.
[ERROR] <...>/MyClass.java:39: Please use class literals for primitives and void -- for example, int.class instead of Integer.TYPE.
This commit improves PersistenceManagedTypesBeanRegistrationAotProcessor
so that it does not attempt to load JPA classes when checking for the
presence of a PersistenceManagedTypes bean. To make it more clear a
check on the presence for JPA has been added to prevent the nested
classes to be loaded regardless of the presence of the bean.
Closes gh-32155
To improve consistency and avoid confusion regarding primitive types
and their wrapper types, this commit ensures that we always use class
literals for primitive types.
For example, instead of using the `Void.TYPE` constant, we now
consistently use `void.class`.
Prior to this commit, SpEL's Indexer incorrectly requested conversion
to wrappers instead of primitives when setting an element in a
primitive array.
This commit addresses this by requesting primitive conversion -- for
example, conversion to `int.class` instead of `Integer.class` when
setting a value in an `int[]` array.
For greater clarity, this commit also switches from using `TYPE`
constants in wrapper classes to primitive class literals -- for
example, from `Integer.TYPE` to `int.class`.

The behavior for the toString() implementation for annotations changed

Prior to this commit, the `RestTemplate` observation instrumentation
would only record `RestClientException` and `IOException` as errors in
the observation. Other types of errors can be thrown by custom
components, such as `ResponseErrorHandler` and in this case they aren't
recorded with the observation.
Also, the current instrumentation does not create any observation scope
around the execution. While this would have a limited benefit as no
application code is executed there, developers could set up custom
components (such as, again, `ResponseErrorHandler`) that could use
contextual logging with trace ids.
This commit ensures that all `Throwable` are recorded as errors with the
observations and that an observation `Scope` is created around the
execution of the client exchange.

Prior to this commit, the alias resolution error message in
SimpleAliasRegistry was misleading.
When a resolution conflict is detected, the IllegalStateException
thrown by resolveAliases(...) now states that the resolved alias is
already registered for an `existingName` instead of the `registeredName`.
See gh-31353
Closes gh-32025
This commit improves SimpleAliasRegistryTests in the following ways.
- Some existing methods have been split up into smaller test methods
which focus on a single use case.
- The use of Mockito mocks has been replaced by a hand-crafted
StubStringValueResolver which ensures that existing aliases and names
are not accidentally replaced by null thereby removing their removing
there mappings inadvertently.
- Several test methods now include inline comments that document the
current state of the aliasMap in order to clarify what is happening
behind the scenes in the ConcurrentHashMap.
- Several test methods warn that the current expectations are based on
ConcurrentHashMap iteration order!
- New @ParameterizedTest which is currently @Disabled but
demonstrates that complex use cases involving placeholder replacement
can be supported consistently -- regardless of the values of the
aliases involved -- but only if alias registration order is honored.

The goal for #31530 was to support bean validation on Set and other
method parameters that are containers of value(s) for which there is
a registered Jakarta Validation ValueExtractor.
Unfortunately, bean validation does not expose the unwrapped value
for a Path.Node, which we need for a method parameter in order to
create a BindingResult for the specific bean within the container,
and the leafBean that we tried to use is really the node at the
very bottom of the property path (i.e. not what we need).
This change removes the use of beanLeaf, restores the logic as it
was before, adds support for arrays, and a new test class for
scenarios with cascaded violations.
See gh-31746
Prior to this commit, the `WebHttpHandlerBuilder` would only configure

This commit builds on top of changes made in gh-29775 and gh-31737.
Before this change, we would allocate several byte arrays even in cases

colocated in memory.
This change ensures that we create a `FastByteArrayOutputStream`
instance with the known request size so that the first allocated segment
can contain the entire content.
If the request size is not know, we will default back on the default
allocation size for the `FastByteArrayOutputStream`.

Prior to this commit, the WebClient observations would have a specific
lifecycle where the observation context is build with a
`ClientRequest.Builder` as tracing needs to add an outgoing request
header before the request is made immutable.
With this setup, the metrics observation handler processes the start
event by increasing the "http.client.requests.active" counter and
collecting tags at this point. Because then the immutable request is not
yet fully built or set on the context, the keyvalues collected by the
observation convention at that point can be incomplete.
This commit ensures that a request is always made available in the
context, even if it is updated right after the observation start. The
only difference between the two should be additional tracing headers and
a request attribute holding the current observation context.
Closes gh-31702

Prior to this commit, the `ConcurrentReferenceHashMap#restructure`
operation would null out the entire references array before starting the
restructuring operation (in case resizing is not necessary).
This could cause at runtime race conditions where a lookup operation
would return null, when the value is actually cached but not accesible
during the restructuring phase.
This commit ensures that, when resizing is not required, a new reference
list is built (purged of null entries) and then assigned to the
reference array. This way, concurrent reads will not return null for
existing entries and there are less chances of re-calculating cache
entries during the restructuring phase.

Introduce ShardingKeyDataSourceAdapter to get shard connections.
This commit introduces a DataSource proxy, that changes the behavior of the getConnection method to use the `createConnectionBuilder()` api to acquire direct shard connections. The shard connection is acquired by specifying a `ShardingKey` that is correspondent to the wanted shard.
While it is not easily possible to create a ConcurrentTaskScheduler
with no scheduled executor, DefaultManagedTaskScheduler has a default
constructor that does that as the JNDI lookup happens in the regular
afterPropertiesSet callback. If such an instance is created manually,
it can throw an unhelpful NullPointerException if one attempts to
schedule a task.
This commit updates ConcurrentTaskScheduler to flag that the scheduled
executor could be `null` and check if that's the case before using it.
This now throws a dedicated exception that should hopefully provide
better context for those upgrading.

This commit introduces a toString() overload in

Closes gh-31719
The getContentAsString method was originally added in d9b8826 to avoid
the extra copying inherent to calling ByteArrayOutputStream.toByteArray;
however, in f83c609 the class was updated to instead use
FastByteArrayOutputStream, and in the process the extra copy was brought
back when getContentAsString was changed to call toByteArray.
Switch to calling toByteArrayUnsafe, a method provided by
FastByteArrayOutputStream, which avoids the extra copy; since we
immediately pass the byte array to the String constructor, and it isn't
accessed anywhere else, the usage is safe.

Prior to this commit, regressions were introduced with gh-31417:
1. the observation keyvalues would be inconsistent with the HTTP response
2. the observation scope would not cover all controller handlers, causing
traceIds to be missing
The first issue is caused by the fact that in case of error signals, the
observation was stopped before the response was fully committed, which
means further processing could happen and update the response status.
This commit delays the stop event until the response is committed in
case of errors.
The second problem is caused by the change from a `contextWrite`
operator to using the `tap` operator with a `SignalListener`. The
observation was started in the `doOnSubscription` callback, which is too
late in some cases. If the WebFlux controller handler is synchronous
non-blocking, the execution of the handler is performed before the
subscription happens. This means that for those handlers, the
observation was not started, even if the current observation was
present in the reactor context. This commit changes the
`doOnSubscription` to `doFirst` to ensure that the observation is
started at the right time.

[[aot.bestpractices.bean-registration]]
== 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.comlext-data-structure]]
=== Avoid Complex Data Structure 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 structure, 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 the `Delegate` as the key.
[[aot.bestpractices.custom-arguments]]
=== Avoid Creating Bean with Custom Arguments
Spring AOT detects what needs to be done to create a bean and translates that in generated code using 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] that leads 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.

{spring-framework-api}/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.
Out-of-the-box, only Spring beans are considered but you can opt-in for scanning using `@ReflectiveScan`.
In the example below, all types of the package `com.example.app` and their subpackages are considered:
include-code::./MyConfiguration[]
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.
By default, `@Reflective` registers an invocation hint 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.
An example of such customization is covered in the next section.

{spring-framework-api}/aot/hint/annotation/RegisterReflection.html[`@RegisterReflection`] is a specialization of `@Reflective` that provides a declarative way of registering reflection for arbitrary types.
NOTE: As a specialization of `@Reflective`, this is also detected if you're using `@ReflectiveScan`.
In the following example, public constructors and public methods can be invoked via reflection on `AccountService`:
`@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.
`@RegisterReflection` can be used as a meta-annotation to provide more specific needs.
{spring-framework-api}/aot/hint/annotation/RegisterReflectionForBinding.html[`@RegisterReflectionForBinding`] is such composed annotation and 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.
The following example registers `Order` for serialization.
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].

For more targeted discovery and testing, Spring Framework ships a dedicated module with core AOT testing utilities, `"org.springframework:spring-core-test"`.

.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.
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.
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
