When a handler method is annotated with `@ResponseStatus(reason="...")`,
Spring MVC will use `HttpServletResponse#sendError` to complete the
response. As a result, the Servlet container will send an HTML error
page and any existing data in the response buffer will be cleared.
This commit clarifies the `@ResponseStatus` Javadoc and ensures that a
message is logged at the WARN level if a handler method is annotated
like this and still returns a non-Void value. In this case, the return
value will be ignored and developers should be aware of this fact.

With this commit, ReactorClientHttpConnector now implements
SmartLifecycle which optionally allows recreating the HttpClient
after ReactorResourceFactory has been updated.
Closes gh-31180
With this commit, ReactorResourceFactory now implements
Lifecycle which allows supporting JVM Checkpoint Restore
in Spring Boot with Reactor Netty server, and helps
to support Reactor Netty client as well.
Closes gh-31178
Prior to this commit, the `RestTemplateAdapter` would manually expand
templated URIs. This means that the `RestTemplate` instance itself would
never see the templated URIs and could not record it in the client
observations at runtime.
This commit ensures that when URI templates are available, the adapter
uses the correct `exchange` method variant.
Fixes gh-31144
This commit schedules blocking I/O operations on the bounded elastic
scheduler, which includes retrieving the content length and writing
the resource (region).
Closes gh-30928
This commit builds on the recently added support for using @AliasFor to
override the `value` attribute in `@Component, and allows a custom
component name to be specified in both @ControllerAdvice and
@RestControllerAdvice via new `name` attributes.
See gh-31089
Closes gh-21108
This commit instruments the new `RestClient` HTTP client for
observability. Since this client is sharing its HTTP infrastructure with
`RestTemplate` and operates on the same request/response types, this
instrumentation reuses the Observation convention and context.
This choice makes sense since one can build a new `RestClient` instance
using a `RestTemplate` instance, effectively reusing the underlying
configuration.

This commit adds support for Kotlin Coroutines to Spring AOP
by leveraging CoroutinesUtils#invokeSuspendingFunction in
AopUtils#invokeJoinpointUsingReflection to convert it to the
equivalent Publisher return value, like in other parts of Spring
Framework.
That allows method interceptors with Reactive support to process
related return values.
CglibAopProxy#processReturnType and JdkDynamicAopProxy#invoke
take care of the conversion from the Publisher return value
to Kotlin Coroutines.
Reactive transactional and HTTP service interface support
have been refined to leverage those new generic capabilities.
Closes gh-22462
This commits adds a getContentAsString method to
ContentCachingRequestWrapper that uses the configured charset without
copying the underlying byte array.
See gh-30709
This commit moves ServerWebExchange Kotlin extensions
where they belong: in the spring-web module with the
org.springframework.web.server package, like
ServerWebExchange itself.
The extensions in the wrong location are deprecated
and semi-automated migration to the new variants is
made possible via @Deprecated + ReplaceWith(...).
Some tests have been added as well.
Closes gh-31046
Java 12 introduced java.lang.Class#componentType() as a shortcut for
getComponentType().
Since we started using arrayType() in fe5560400c, this commit switches
to componentType() for consistent API usage style.
When the content length is known, use readNBytes on the InputStream in
StringHttpMessageConverter, which avoids some extra copying and allocations.
Closes gh-30942
This commit updates WebMVC converters and WebFlux
encoders/decoders to support custom serializers
with Kotlin Serialization when specified via
a custom SerialFormat.
It also turns the serializers cache to a non-static
field in order to allow per converter/encoder/decoder
configuration.
Closes gh-30870
Where possible, switch to the Long.parseLong variant that accepts a
start and end index for the supplied CharSequence, thus avoiding making
unnecessary copies of the String input.
Closes gh-30710
This commit changes the default request factory from the
SimpleClientHttpRequestFactory to the JdkClientHttpRequestFactory if
available. It also adds detection logic for OkHttp and Jetty.
Now that HttpClientAdapter is deprecated and replaced by HttpExchangeAdapter
and ReactorHttpExchangeAdapter, our tests should use the new contracts.
See gh-30117
This commit improves the documentation for the
`ShallowEtagHeaderFilter`, stating that it is only meant to support a
subset of conditional HTTP requests: GET requests with "If-None-Match"
headers. Other headers and state changing HTTP methods are not supported
here, as the filter only operates on the content of the response and has
no knowledge of the resource being served.
