SmartHttpMessageConverter is similar to GenericHttpMessageConverter,
but more consistent with WebFlux Encoder and Decoder contracts, with
the following differences:
- A ResolvableType parameter is used instead of the Type one
- The MethodParameter can be retrieved via the ResolvableType source
- No contextClass parameter
- `@Nullable Map<String, Object> hints` additional parameter for write
and read methods
This commit also refines RestTemplate#canReadResponse in order to use
the most specific converter contract when possible.

Prior to this commit, the fix for gh-32730 disabled the involvment of
the osbervation filter for async dispatches. Instead of relying on ASYNC
dispatches to close the observation for async requests, this is now
using an async listener instead: async dispatches are not guaranteed to
happen once the async request is handled.
This change caused another side-effect: because async dispatches are not
considered anymore by this filter, the observation scope is not
reinstated for async dispatches. For example, `ResponseBodyAdvice`
implementations do not have the observation scope opened during their
execution.
This commit re-enables async dispatches for this filter, but ensures
that observations are not closed during such dispatches as this will be
done by the async listener.
Fixes gh-33091
Prior to this commit, @TestBean factory methods had to be defined in
the test class, one of its superclasses, or in an implemented
interface. However, users may wish to define common factory methods in
external classes that can be shared easily across multiple test classes
simply by referencing an external method via a fully-qualified method
name.
To address that, this commit introduces support for referencing a
@TestBean factory method via its fully-qualified method name following
the syntax <fully-qualified class name>#<method name>.
Closes gh-33125
Fix argument in call to applyReturnValueValidation()
method in MethodValidationInterceptor.java. Method
argument was passed instead of the return value of the
method that was being validated.

Prior to this commit, if ModelMap was used as an argument type in a
WebFlux controller method, the user encountered an exception similar to
the following.
java.lang.IllegalStateException: argument type mismatch
Controller [example.SampleController]
Method [java.lang.String example.SampleController.index(org.springframework.ui.ModelMap)] with argument values:
[0] [type=org.springframework.validation.support.BindingAwareConcurrentModel] [value={}]
However, the above error message is a bit cryptic since the error
occurs while attempting to invoke the controller method with an
instance of BindingAwareConcurrentModel which is not compatible with
ModelMap. More importantly, this error message does not explicitly
convey to the user that a ModelMap is not supported.
This commit improve the diagnostics for the user in such scenarios by
rejecting the use of ModelMap upfront in WebFlux.
Consequently, for the same use case as above, the user now encounters
an exception similar to the following.
java.lang.IllegalStateException:
Could not resolve parameter [0] in
java.lang.String example.SampleController.index(org.springframework.ui.ModelMap):
No suitable resolver
Closes gh-33109
Prior to this commit, the "Method Arguments" documentation for WebFlux
in the reference manual stated that WebFlux controller methods can
accept arguments of type Map, Model, or ModelMap to access the model.
However, ModelMap is actually not supported and results in exception
due to a type mismatch.
This commit updates the documentation to reflect this.
In addition, this commit updates related Javadoc and tests to avoid
mentioning or using ModelMap in WebFlux.
Closes gh-33107
According to the official FreeMarker documentation, Spring's
FreeMarkerView implementations should be configuring the
output_encoding for template rendering.
To address that, this commit modifies the FreeMarkerView
implementations in Web MVC and WebFlux to explicitly set the
output_encoding for template rendering.
See https://freemarker.apache.org/docs/pgui_misc_charset.html#autoid_53
See gh-33071
Closes gh-33106
Prior to this commit, the comment in the XML configuration example in
the Method Injection section of the reference manual referred to the
wrong bean names.
Closes gh-33096
Prior to this commit, the `ProtobufMessageConverter` used in messaging
would try and serialize the message payload by calling "toString()" on
it in order to pass it to the Protobuf JSON encoder.
While this works for `String` payloads, this fails for `byte[]` types.
This commit ensures that such `byte[]` are first converted to `String`
instances using the given charset first.
Fixes gh-27408
Prior to this commit, RequestMappingViewResolutionIntegrationTests
invoked the following:
configurer.setTemplateLoaderPath(
"classpath*:org/springframework/web/reactive/view/freemarker/");
However, that configuration is invalid since `classpath*:` is not
supported for a `templateLoaderPath`.
Despite that, the tests still passed since FreeMarkerConfigurer already
registers a new ClassTemplateLoader(FreeMarkerConfigurer.class, ""),
which automatically finds template files in the same package as
FreeMarkerConfigurer (for the "spring.ftl" macro library support) and
coincidentally RequestMappingViewResolutionIntegrationTests as well
(which resides in the same package).
This commit therefore removes the invalid configuration and adds a
comment to explain what's going on.
This commit replaces `@Nonnull(when = When.MAYBE)` meta-annotation in
org.springframework.lang.Nullable by `@CheckForNull` in order to
prevent "unknown enum constant When.MAYBE" compilation warnings.
IntelliJ IDEA 2024.1.2+ is required to interpret correctly the related
annotations.
