This commit adds a reference documentation section explaining how
applications can use custom `HttpServiceArgumentResolver`
implementations to support complex application types as method
parameters in HTTP interfaces.

This commit updates the whole Spring Framework codebase to use JSpecify
annotations instead of Spring null-safety annotations with JSR 305
semantics.
JSpecify provides signficant enhancements such as properly defined
specifications, a canonical dependency with no split-package issue,
better tooling, better Kotlin integration and the capability to specify
generic type, array and varargs element null-safety. Generic type
null-safety is not defined by this commit yet and will be specified
later.
A key difference is that Spring null-safety annotations, following
JSR 305 semantics, apply to fields, parameters and return values,
while JSpecify annotations apply to type usages. That's why this
commit moves nullability annotations closer to the type for fields
and return values.

As a preparation to using a Kotlin 2 baseline, this commit stops using
Java code snippets in Kotlin ones in order to avoid redeclaration
errors.

This commit adapts AOT support in various modules after the RuntimeHints
and related deprecation changes.
`MemberCategory.INTROSPECT_*` hints are now removed and
`MemberCategory.*_FIELDS` are replaced with
`MemberCategory.INVOKE*_FIELDS` when invocation is needed.
Usage of `RuntimeHintsAgent` are also deprecated.
Closes gh-33847
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.
Closes gh-33132
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.

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.

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.
