CharSequenceEncoder now supports all MIME types, however since encoding
Flux<String> can overlap with other encoders (e.g. SSE) there are now
two ways to create a CharSequenceEncoder -- with support for text/plain
only or with support for any MIME type.
In WebFlux configuration we insert one CharSequenceEncoder for
text/plain (as we have so far) and a second instance with support for
any MIME type at the very end.

This commit changes `ServerResponse` and subtypes to use properties
instead of fields during response rendering. This allows for overriding
these methods in a response subclass.
This commit changes the `HandlerFilterFunction.ofResponseProcessor`
method signature to return `Mono<ServerResponse>`, to better cooperate
with response builders (which all return a `Mono`).
Instead of accepting List<Encoder|Decoder> and then look for the first
to support JSON, always expect a single JSON [Encoder|Decoder] and use
that unconditionally.
When writing use the nested ResolvableType instead of the Class of the
actual value which should better support generics.
Remove the SSE hint and pass "text/event-stream" as the media type
instead to serve as a hint. We are expecting a JSON encoder and using
it unconditionally in any case so this should be good enough.
Consolidate JsonView hint extraction in shared base class.
Rename base class from AbstractJackson2Codec to Jackson2CodecSupport
since the class mainly provides support methods.
ServerHttpMessage[Reader|Writer] are now expected for WebFlux,
annotated controller endpoint and subsequently the instanceof checks
for HttpMessage[Reader|Writer] vs ServerHttpMessage[Reader|Writer] can
be removed from AbstractMessageReaderArgumentResolver and
AbtractMessageWriterResultHandler.
Support for flushing in EncoderHttpMessageWriter is now driven from a
configurable list of "streaming" media types with the list including
"application/stream+json" by default.
As a result Jackson2ServerHttpMessageWriter is no longer needed.
ServerHttpEncoder and ServerHttpDecoder are HTTP-specific
specializations that can prepare encoding and decoding hints from
extra information available on the server side.
As a result Jackson2ServerHttpMessageReader is no longer needed.
There is a natural way to implement ServerHttpMessage[Reader|Writer]
from [Encoder|Decoder]HttpMessageWriter by resolving hints first via
a protected method and then delegating to the regular read or write.
There is no downside either since it does not prevent
[Encoder|Decoder]HttpMessageWriter from being used for both client and
server scenarios while they're more useful.
As a positive side effect AbstractServerHttpMessage[Reader|Writer] can
be removed further simplfications can be made (in a future commit) to
accept ServerHttpMessageWriter for configuration purposes on the server
side and remove instanceof checks for ServerHttpMessageWriter.
This commit updates the main code base to conform to the dropped JAF
dependency in MediaTypeFactory. Specifically, it
- Removes JAF detection (JAF_PRESENT constants)
- Deprecated useJaf properties, with no direct replacement.
- Updated docs to remove JAF references, in favor of MediaTypeFactory.

Fold ResourceRegionHttpMessageWriter into ResourceHttpMessageWriter.
The latter was a private helper (not meant to be exposed) and the two
have much in common now sharing a number of private helper methods.
The combined class does not extend AbstractServerHttpMessageConverter
from which it was not using anything.
Internally the combined class now delegates directly to ResourceEncoder
or ResourceRegionEncoder as needed. The former is no longer wrapped
with EncoderHttpMessageWriter which is not required since "resource"
MediaType determination is a bit different.
The consolidation makes it easy to see the entire algorithm in one
place especially for server side rendering (and HTTP ranges). It
also allows for consistent determination of the "resource" MediaType
via MediaTypeFactory for all use cases.
ResourceRegionHttpMessageWriter no longer extends from
EncoderHttpMessageWriter freeing it to pass the correct content type
into the encoder.
Considering that the main benefit of EncoderHttpMessageWriter is to
deal with content type fallback cases, there is nothing to be missed.
Furthermore ResourceRegionHttpMessageWriter is a package private class
that is used internally within ResourceHttpMessageWriter and never
exposed externally as a an actual HttpMessageWriter.
Issue: SPR-15358
CompositeHttpHandler is public and called ContextPathCompositeHandler.
Also an overhaul of the Javadoc on HttpHandler, WebHttpHandlerAdapter,
and ContextPathCompositeHandler.
Switch from extension to delegation model, i.e. delegating to
InvocableHandlerMethod, so that only sync invocation is exposed and
only resolvers of type SyncHandlerMethodArgumentResolver are allowed
to be configured in a cleaner fashion.
Currently the BOM versions are:
* reactor-core 3.0.6.BUILD-SNAPSHOT
* reactor-netty 0.6.2.BUILD-SNAPSHOT
This commit fixes as well a few deprecations in reactor-core.
From spring-webflux to spring-web test sources since it is perfectly
usable for testing Spring MVC annotation method support.
Potentially to be promoted further up for use in any module that has
annotation method support. It has spring-core dependencies only
In preparation for SPR-15132.
Turn the BindingContextFactory into ModelInitializer (both package
private) since creating BindingContext itself is quite simple.
The ModelInitializer also has only one field and no need to be aware
of fields the RequestMappingHandlerAdapter.
