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

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.
Remove RSocketStrategies argument from the contract to avoid having to
pass them every time especially by application components, like an
implementation of a Spring Security matcher.
Decouple DefaultMetadataExtractor from RSocketStrategies in favor of
a decoders property and an internal DataBufferFactory, which does not
need to be the shared one as we're only wrapping ByteBufs.
If there is more than one non-basic codec (e.g. CBOR and JSON)
RSocketRequester.Builder takes the mime type of the first one rather
than giving up. It is a valid scenario (JSON for server responding to
browser, and CBOR for client talking to server) and it is the default
situation in Boot, and after all the point here is to pick some default
as best as we can with the worst possible outcome being a server
refusing the connection if it doesn't support the mime type. Beyond
that applications can set the dataMimeType on the builder explicitly.
To match that change this commit also ensures RSocketMessageHandler
rejects proactively data mime types it does not support at the point
of accepting a connection.
This commit ensures getRSocketStrategies() now reflects the state of
corresponding RSocketMessageHandler properties even if those change
after a call to setRSocketStrategies.
RSocketMessageHandler has default Encoder/Decoder initializations
consistent with the recent changes to RSocketStrategies.
Now that responder RSocketStrategies also exposes responder strategies,
AnnotationClientResponderConfigurer is reduced and no longer needs to
be public. This commit folds it into RSocketMessageHandler as a nested
class and exposes it as a ClientRSocketFactoryConfigurer through a
static method that accepts the handlers to use.
Effectively a shortcut for creating RSocketMessageHandler, giving it
RSocketStrategies, calling afterPropertiesSet, and then the instance
createResponder.
See gh-23314
Now that RSocketStrategies has default settings it makes sense to have
a create() shortcut vs builder().build().
This commit also updates tests to take advantage of improvements in this
and the previous two commits.
See gh-23314
1. RSocketStrategies hooks in the basic codecs from spring-core by
default. Now that we have support for composite metadata, it makes
sense to have multiple codecs available.
2. RSocketStrategies is pre-configured with NettyDataBufferFactory.
3. DefaultRSocketRequesterBuilder configures RSocket with a frame
decoder that matches the DataBufferFactory choice, i.e. ensuring
consistency of zero copy vs default (copy) choice.
4. DefaultRSocketRequesterBuilder now tries to find a single non-basic
decoder to select a default data MimeType (e.g. CBOR), or otherwise
fall back on the first default decoder (e.g. String).
See gh-23314
The new interface supersedes ClientResponderFactory and is more general,
for any RSocketFactory customization.
DefaultClientResponderFactory implements the new interface and is
renamed to AnnotationClientResponderConfigurer.
See gh-23170
Simplify the creation of MetadataExtractor by not requiring
RSocketStrategies up front. The strategies are already configured in higher
level places like RSocketMessageHandler that invoke the MetadataExtractor.
The strategies are now passed in as an argument to the extract method.
Prior to this commit, the `RSocketRequester.Builder` would allow to
configure directly annotated handlers for processing server requests.
This lead to a package tangle where the `o.s.messaging.rsocket` would
use classes from `o.s.messaging.rsocket.annotation.support` package.
This commit introduces the `ClientResponderFactory` interface for
configuring a responder on the client RSocket factory. Its goal is
to be compatible with future changes with a functional variant for
RSocket handlers.
Closes gh-23170
The new annotation helps to differentiate the handling of connection
level frames (SETUP and METADATA_PUSH) from the 4 stream requests.
Closes gh-23177
This commit renames RSocketRequester.RequestSpec data extension to
dataWithType to avoid shadowing issues and adds Publisher<T> and Flow<T>
variants to provide automatic reified type parameter resolution for
those types. It also makes RSocketRequester consistent with the
changes introduced via 2b4d6ce354 in WebFlux.
