Prior to this commit, when searching for annotations using the
TYPE_HIERARCHY_AND_ENCLOSING_CLASSES strategy an exception could be
thrown while attempting to load the enclosing class (e.g., a
NoClassDefFoundError), thereby halting the entire annotation scanning
process.
This commit makes this search strategy defensive by logging exceptions
encountered while processing the enclosing class hierarchy instead of
allowing the exception to halt the entire annotation scanning process.
The exception handling is performed by
AnnotationUtils.handleIntrospectionFailure() which only allows an
AnnotationConfigurationException to propagate.
See gh-24136
Prior to this commit, the enclosing class was always eagerly loaded
even if the annotation search strategy was not explicitly
TYPE_HIERARCHY_AND_ENCLOSING_CLASSES.

This commit restores the interpretation of JSON as UTF-8 by default that
was removed in #bc205e0 and also ensures a charset is not appended
automatically to "application/json".

Given the following improperly configured composed @RequestMapping
annotation:
@Retention(RetentionPolicy.RUNTIME)
@RequestMapping
@interface PostApi {
@AliasFor("value")
String[] path() default {};
@AliasFor(annotation = RequestMapping.class, attribute = "path")
String[] value() default {};
}
Prior to this commit, an attempt to process the above annotation
resulted in an exception similar to the following, which is not
especially helpful to discern the problem.
> Attribute 'value' in annotation [PostApi] must be declared as an
> @AliasFor 'path', not 'path'.
This commit improves the exception message for such scenarios,
resulting in an exception message similar to the following.
> Attribute 'value' in annotation [PostApi] must be declared as an
> @AliasFor attribute 'path' in annotation [PostApi], not attribute
> 'path' in annotation [RequestMapping].
Closes gh-24168
Spring Framework 5.2 introduced support for caching @ControllerAdvice
beans; however, this caching was also applied incorrectly to
non-singleton beans.
This commit addresses this regression by only caching singleton
@ControllerAdvice beans.
Closes gh-24157
Update `ResolvableType` so that variable referenced can be resolved
against wildcard types. Prior to this commit, given a type:
Map<String, ? extends List<? extends CharSequence>>
Calling `type.getGeneric(1).asCollection().resolveGeneric()` would
return `null`. This was because the `List` variable `E` referenced a
wildcard type which `resolveVariable` did not support.
Closes gh-24145
Spring Framework 5.2 introduced a regression for implicit aliases
declared via @AliasFor. Specifically, Spring's merged annotation
algorithms stopped honoring default values for implicit alias pairs if
the composed annotation was used without specifying the aliased
attributes.
This commit fixes this regression.
Closes gh-24110
As a follow-up of gh-23961, this change provides a way for custom codecs
to align with the default codecs' behavior on common features like
buffer size limits and logging request details.

Prior to this commit, developers could configure their WebClient to use
their custom `ExchangeStrategies`, by providing it in the
`WebClient.Builder` chain.
Once created, an `ExchangeStrategies` instance is not mutable, which
makes it hard for further customizations by other components. In the
case of the reported issue, other components would override the default
configuration for the codecs maxInMemorySize.
This commit makes the `ExchangeStrategies` mutable and uses that fact to
further customize them with a new `WebClient.Builder#exchangeStrategies`
`Consumer` variant. This commit is also deprecating those mutating
variants in favor of a new `WebClient.Builder#exchangeStrategies` that
takes a `ExchangeStrategies#Builder` directly and avoids mutation issues
altogether.
Closes gh-23961
