Normally consumes matches the "Content-Type" header but what should be done if
there is no content? This commit adds checks for method parameters with
@RequestBody(required=false) and if "false" then also match requests with no content.
Closes gh-22010
Deprecate the public `StandardMetadata` constructors to make it clearer
that these classes should not be instantiated directly. A new
`AnnotationMetadata.introspect` factory method has been added which
can now be used to obtain instances.
This change will allow use to make the constructors package private
and drop the `nestedAnnotationsAsMap` parameter in a future release.
Closes gh-22906
Replace the existing ASM based readers with new implementations that
also support MergedAnnotations. The meta-data classes themselves are
now immutable, and constructed via separate reader classes.
The `SimpleMetadataReader` class has been updated to return the new
classes, however the old ones remain since some of them are public
and might be being used directly.
Closes gh-22884
Add `AnnotatedTypeMetaData.getAnnotations()` that can be used to access
annotation details using the `MergedAnnotations` interface.
Where possible, the existing annotation methods have been migrated to
call `getAnnotation()`, rather than needing their own implementation.
The existing ASM based meta-data implementations have not been updated
since they will be deprecated and replaced in a subsequent commit.
See gh-22884
Update `StandardAnnotationMetadata` to use `ReflectionUtils` when
obtaining declared methods. This update is primarily so that the common
method cache can be used.
Closes gh-22907
Update `StandardAnnotationMetadata` and `AnnotationMetadataReadingVisitor`
so that `java.lang.annotation` annotations are consistently skipped.
Closes gh-22885
Update ASM based metadata readers so that only RetentionPolicy.RUNTIME
annotations are exposed. This aligned behavior with the reflection based
implementation.
Closes gh-22886
Add a factory method to `MergedAnnotation` that allows an instance to
be created for an explicit collection of root annotations. This method
will allow ASM based readers to expose a `MergedAnnotation` instance
that has root annotations loaded from bytecode, and meta-annotations
loaded using reflection.
See gh-22884
Update TypeMappedAnnotation so that Strings can be used to represent
Class attribute values. This will allow ASM annotation readers to
present a `MergedAnnotation` instance without necessarily having the
actual class values on the classpath.
When the underlying value is a String, any calls to
`getValue(name, String.class)` or `asMap(Adapt.CLASS_TO_STRING)` will
simply return the original String. Calls that need the actual Class
result (such as `getClass`) will use `Class.forName` and may throw
a `ClassNotFoundException` at that point.
This commit also allows an empty Object[] to be used to represent
any empty primitive array.
See gh-22884
Rename `from` to `of` for the `MergedAnnotation` factory methods that
work with Maps. The previous name was a little confusing, especially
when an annotation source parameter was specified. The new method name
helps to make it clearer when the user is explicitly defining the
attributes of the annotation, as opposed to picking them up from the
source.
Add a `getTypeHierarchy()` method to `MergedAnnotation` that can be used
to return the full type hierarchy information. This method is
specifically designed to be used in combination with
`MergedAnnotationPredicates.unique`.
This update also allows us to delete the `parentAndType` method
from `AnnotatedElementUtils`.
Closes gh-22908
We now correctly unwrap suspended resources instead capturing
the Mono emitting suspended resources.
We also properly continue resume by chaining resume Mono's
instead of terminating eagerly.
This commit introduces the DefaultMultipartMessageReader, a fully
reactive multipart parser that does have any third party dependencies.
Closes gh-21659
Added two methods to DataBufferUtils:
* matcher(byte[]), which returns a Matcher object that can be used to
find a delimiter in a data buffer.
* split(Publisher<DataBuffer>, byte[] delimiter), which splits a given
stream of data buffers around a given delimiter.
We now use Flux.usingWhen() instead materialize/dematerialize operators
to reuse Reactor's resource closure.
Until usingWhen() accepts a BiFunction to consume error signals,
we need to map error signals outside of usingWhen which requires
re-wrapping of the ReactiveTransaction object.
Also, reuse the current TransactionContext to leave Transaction
creation/propagation entirely to ReactiveTransactionManager instead
of creating new TransactionContexts.
