Prior to this commit, Spring MVC and WebFlux would consider the
"kotlinx.serialization" JSON codecs and converters in addition to other
JSON alternatives like Jackson, Gson and Jsonb.
This would cause issues because while in most cases this library is only
involved if the type is annotated with "@Serializable", this is not true
for Java enums. In this particular case, the codec shadows Jackson and
causes issues.
This commit now considers kotlinx.serialization JSON support as an
alternative to Jackson. Just like Jsonb and GSON, this is only
auto-detected if Jackson is not present.
We received consistent feedback that kotlinx.serialization is popular in
Kotlin libraries and is often a transitive dependency. As a result, we
cannot consider its presence on the classpath as a strong enough signal
to configure it by default.

This commit deprecates the `<mvc:*` XML configuration namespace for
configuring Spring MVC applications. This configuration model is lagging
behind in the 6.x generation already and we don't intend to invest in
this space to close that gap.
As of 7.0, using this XML namespace will result in a WARN log message.
This commit also states our intent in the reference documentation.
Closes gh-34063
Since Joda-Time support was removed in Spring Framework 6.0, this commit
removes obsolete mentions of Joda-Time in the reference guide and Javadoc.
See gh-27426
Closes gh-33881
This commit removes all references to the Resin Servlet container, as it
is not supported as of Spring Framework 6.0 because we require a
JakartaEE baseline.
Closes gh-33772
This commit fixes the issue where the regex pattern in the reference documentation
was not rendering correctly for the `/projects/{project:[a-z]+}/versions` mapping.
Closes gh-33766
Since we now use asciidoctor-tabs instead of spring-asciidoctor-backends,
we no longer need the `role="primary"` and `role="secondary"` attributes
for tab groups.
Closes gh-33506
On the client side, supports `name=value` pairs. Placeholders in values
are resolved by the `embeddedValueResolver`.
On the server side, additionally supports `name` and `!name` syntax.
Closes gh-33309
This commit introduces a notion of different styles for the formatting
of Duration.
The `@DurationFormat` annotation is added to ease selection of a style,
which are represented as DurationFormat.Style enum, as well as a
supported time unit represented as DurationFormat.Unit enum.
DurationFormatter has been retroffited to take such a Style,
optionally, at construction. The default is still the JDK style a.k.a.
ISO-8601.
This introduces the new SIMPLE style which uses a single number + a
short human-readable suffix. For instance "-3ms" or "2h".
This has the same semantics as the DurationStyle in Spring Boot and
is intended as a replacement for that feature, providing access to the
feature to projects that only depend on Spring Framework.
Finally, the `@Scheduled` annotation is improved by adding detection
of the style and parsing for the String versions of initial delay, fixed
delay and fixed rate.

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.
