Take a slice of the metadata if not using composite metadata to allow
reading it multiple times. For composite metadata this is not an isuse
as it is ensured by the underlying RSocket Java API.
This commit renames the `metadataExtractors` method to something that is
closer to the actual intent: addming new metadata extractors against the
registry given as a parameter of the `Consumer`.
The method is renamed to `metadataExtractorRegistry`.
This commit makes it possible to send requests without
requiring to call data(Mono.empty()). It introduces a
dedicated MetadataSpec interface and merge ResponseSpec
into RequestSpec for more flexibility.
Closes gh-23649
Prior to this commit, customizing the extraction of RSocket metadata
from frames would require developers to override the default
`MetadataExtractor` while configuring `RSocketStrategies`.
This touches on many infrastructure parts, whereas the goal is just to
configure an extra metadata entry extractor using already configured
codecs.
This commit adds a way to register metadata entry extractors on the
`RSocketStrategies` builder with a `Consumer`-based API.
Closes gh-23645
This allows encoding of metadata values externally via some
existing API for encoding RSocket metadata, rather than relying on
registered Encoders.
Also remove explicit checks for DataBuffer since those are supported
through the DataBufferEncoder (registered by default).
See gh-23513
For public use, these constants aren't ideally exposed through an SPI
like MetadataExtractor, and there isn't any other obvious place either.
In practice the only public API where these can be passed in is
RSocketRequester and RSocketMessageHandler both of which already
default to composite metadata anyway, leaving only the routing MimeType
to be used potentially but much less likely.
Due to existence of similar constants in the RSocket itself, i.e.
WellKnownMimeType, we can get by internally too without declaring
MimeType constants from a central place.
This commit removes the JUnit 4 dependency from all modules except
spring-test which provides explicit JUnit 4 support.
This commit also includes the following.
- migration from JUnit 4 assertions to JUnit Jupiter assertions in all
Kotlin tests
- migration from JUnit 4 assumptions in Spring's TestGroup support to
JUnit Jupiter assumptions, based on org.opentest4j.TestAbortedException
- introduction of a new TestGroups utility class than can be used from
existing JUnit 4 tests in the spring-test module in order to perform
assumptions using JUnit 4's Assume class

Deprecate all mutation methods in `MethodParameter` in favor of factory
methods that return a new instance. Existing code that previously relied
on mutation has been updated to use the replacement methods.
Closes gh-23385
Expecting data first and metadata second aligns better with the single
arg variant that accepts data. This is also consistent with the
RSocket API in the create methods of ByteBufPayload and DefaultPayload.
Use rsocketStrategies field with mutate() to ensure consistency
with internal state.
Remove transparent initialization of decoders in MetadataExtractor
and expect them to be set to avoid unintended side effects.
