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.

This commit restructures the section on MockMvc so that the anchors
are easier to read. The standard integration has moved to a
Hamcrest Integration section at the same level as HtmlUnit Integration,
and a new AssertJ Integration section has been created.
Closes gh-32454
This commit adds support for Kotlin BeanPostProcessor beans which should
be defined in a companion object and annotated with `@JvmStatic`.
Closes gh-32946
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
types, it was not possible to declare the same exception type on
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")
public String handle(IllegalArgumentException exc, Model model) {
model.addAttribute("error", new ErrorMessage(exc.getMessage(), 42));
return "errorView";
}
```
This commit implements support in both Spring MVC and Spring WebFlux.
Closes gh-31936
This commit extract spring-related links and recurring external links
into asciidoctor attributes to be used by the Antora toolchain.
It notably homogenizes links to:
- IETF RFCs
- Java Community Process JSRs
- the Java API Documentation (on the Java 17 version)
- Kotlin documentations (on the Kotlinlang.org version)
- the Spring Boot reference guide (on the `html` version)
This commit also reworks most link attributes to follow a
Project-Category-Misc syntax. For example, `spring-boot-docs` rather
than `docs-spring-boot`.
Finally, it makes an effort to clean up remainders from the previous
documentation toolchain, namely the `docs/asciidoc` folder and
`modules/ROOT/pages/attributes.adoc` file.
Closes gh-26864

This commit adds a link in the package-overview pages of KDoc and
Javadoc, pointing to the other documentation's own page.
In order for local tests to work, the build has been slightly modified
to align with the directory structure in the distributed documentation
zip (and consequently with that of the deployed documentation website).
Lastly, the javadoc build was fixed to include the `overview.html` again
in the resulting HTML index, since this is where the KDoc link is added.

Prior to this commit, `@Async` and `@EventListener` annotated methods
would lose the the logging and observation contexts whenever their
execution was scheduled on a different Thread.
The Context Propagation library supports this use case and can propagate
context values in ThreadLocals, Reactor Context and more.
This commit introduces a new `TaskDecorator` implementation that
leverages the Context Propagation library. When configured on a
`TaskExecutor`, this allows to properly propagate context value through
the execution of the task.
This implementation is completely optional and requires the
"io.micrometer:context-propagation" library on the classpath. Enabling
this feature must be done consciously and sometimes selectively, as
context propagation introduces some overhead.
Closes gh-31130
This commit adds observability support for Jakarta JMS support in
spring-jms support. This feature leverages the `JmsInstrumentation`
infrastructure in `io.micrometer:micrometer-core` library.
This instruments the `JmsTemplate` and the `@JmsListener` support to
record observations:
* "jms.message.publish" when the `JmsTemplate` sends a message
* "jms.message.process" when a message is processed by a `@JmsListener`
annotated method
The observation `Convention` and `Context` implementations are shipped
with "micrometer-core".
Closes gh-30335
This commit enhances the `ScheduledAnnotationBeanPostProcessor` to
instrument `@Scheduled` methods declared on beans. This will create
`"tasks.scheduled.execution"` observations for each execution of a
scheduled method. This supports both blocking and reactive variants.
By default, observations are no-ops; developers must configure the
current `ObservationRegistry` on the `ScheduledTaskRegistrar` by using a
`SchedulingConfigurer`.
Closes gh-29883
Prior to this commit, the Observation instrumentation for Reactive
server applications was implemented with a `WebFilter`. This allowed to
record observations and set up a tracing context for the controller
handlers.
The limitation of this approach is that all processing happening at a
lower level is not aware of any observation. Here, the
`HttpWebHandlerAdapter` handles several interesting aspects:
* logging of HTTP requests and responses at the TRACE level
* logging of client disconnect errors
* handling of unresolved errors
With the current instrumentation, these logging statements will miss the
tracing context information. As a result, this commit deprecates the
`ServerHttpObservationFilter` in favor of a more direct instrumentation
of the `HttpWebHandlerAdapter`. This enables a more precise
instrumentattion and allows to set up the current observation earlier in
the reactor context: log statements will now contain the relevant
information.
Fixes gh-30013
Updated the Spring Framework documentation to include an example of using Vavr's Try monad to trigger transaction rollbacks when a @Transactional-annotated method returns a Failure. The modified documentation demonstrates how to use Try in a transactional method and how to check if an exception has been wrapped inside a Try.Failure instance. Additionally, a link to the official Vavr documentation was added to provide more information on the Try method.
