This commit deprecates MediaType.APPLICATION_JSON_UTF8 and
MediaType.APPLICATION_PROBLEM_JSON_UTF8 in favor of
MediaType.APPLICATION_JSON and MediaType.APPLICATION_PROBLEM_JSON since
UTF-8 encoding is now handled correctly by most browsers
(related bug has been fixed in Chrome since September 2017).
MediaType.APPLICATION_JSON is now used as the default JSON content type.
Closes gh-22788
Support for suspending handler methods introduced in Spring
Framework 5.2 M1 does not detect types correctly and does not
support suspending handler methods returning Flow which is a
common use case with WebClient.
This commit fixes these issues and adds Coroutines integration
tests.
Closes gh-22820
Closes gh-22827
Following on 3ebbfa2191 where the local
refCount was removed in favor of using the internal refCount of the
native data buffer, this commit ensures that LeakAwareDataBufferFactory
uses a PooledDataBufferFactory delegate by default.
There are also fixes for test issues with eager allocation uncovered by
these changes in StringDecoder and ResourceDecoder.
An empty path mapping in an @RequestMapping now consistently matches to
empty paths regardless of whether there are both type and method level,
annotations, or method-level only.
Closes gh-22543
This commit moves the WebFlux getMappingPathPatterns() implementation
from RequestMappingHandlerMapping to
RequestMappingInfoHandlerMapping so that subclasses of the latter no
longer need to re-implement the method.
See gh-22543
This commit revises the signature of getMappingPathPatterns() in
AbstractHandlerMethodMapping to return a set of PathPatterns instead of
a set of Strings.

Commit c0b52d09f5 introduced support for
throwing an exception if a @RequestMapping handler method in a Spring
MVC controller was mapped to an empty path. This had negative side
effects for applications that intentionally mapped to an empty path,
potentially alongside a mapping to an explicit path for the same
handler method.
This commit addresses this by logging a warning (instead of throwing an
exception) if a @RequestMapping method is mapped only to empty paths.
This commit also introduces the same support for WebFlux-based
@RequestMapping handler methods.
Closes gh-22543
Flow is a Kotlin Coroutines related cold asynchronous
stream of the data, that emits from zero to N (where N
can be unbounded) values and completes normally or with
an exception.
It is conceptually the Coroutines equivalent of Flux with
an extension oriented API design, easy custom operator
capabilities and some suspending methods.
This commit leverages Flow <-> Flux interoperability
to support Flow on controller handler method parameters
or return values, and also adds Flow based extensions to
WebFlux.fn. It allows to reach a point when we can consider
Spring Framework officially supports Coroutines even if some
additional work remains to be done like adding
interoperability between Reactor and Coroutines contexts.
Flow is currently an experimental API that is expected to
become final before Spring Framework 5.2 GA.

WebFlux.fn RouterFunctionDsl#invoke and CoRouterFunctionDsl#invoke
were wrongly exposed on public API and have never been designed to
be used by end users, but rather only invoked from router { } or
coRouter { } builders.
To fix that, avoiding this method being accessible from the DSL and
for the sake of consistency with WebMvc.fn RouterFunctionDsl,
Spring Framework 5.2 turns public fun invoke() method to
an internal fun build() one.
As a consequence RouterFunctionDsl and CoRouterFunctionDsl are not
open anymore, they are expected to be extended via Kotlin
extensions if needed.
Closes gh-22736
This commit changes the main configuration classes for Spring MVC and
Spring WebFlux to not call other bean methods when setting up the web
infrastructure. This allows configuration classes extending
`DelegatingWebFluxConfiguration` and `DelegatingWebMvcConfiguration`
to opt-in the lite-mode, as introduced in gh-22461.
This commit improves CORS support by:
- Using CORS processing only for CORS-enabled endpoints
- Skipping CORS processing for same-origin requests
- Adding Vary headers for non-CORS requests
It introduces an AbstractHandlerMapping#hasCorsConfigurationSource
method in order to be able to check CORS endpoints efficiently.
Closes gh-22273

As of Coroutines 1.2.0-alpha, Dispatchers.Unconfined
is a stable API so we can leverage it in order to get
better performances in our Reactive to Coroutines
bridge.
