At present Tomcat expects a WriteListener to be registered immediately
on the initial thread so for the time being this commit ensures the
WriteListener is registered unconditionally for every request.
Issue: SPR-14772, SPR-14803
This commit removes factory methods for `RequestMappingHandlerMapping`
and `RequestMappingHandlerAdapter` from `WebReactiveConfigurer`.
`WebReactiveConfigurer` should promote only common customizations;
those factory methods should be overridden when extending
`WebReactiveConfigurationSupport`, in advanced configuration scenarios.
This commit replaces the lazy URI and headers initialization in the
reactive ServerHttpRequest in favor of eager initialization at
construction time. Both the URI and headers are nearly guaranteed to
be accessed for every request (URI for application path, headers for
"Origin" header).
Query params are still lazily parsed but parsing is idemptotent and
in the unlikely case of concurrent access (it's the framework that
typically accesses query params) it maybe parsed twice but should
be side effect free still.
Cookies are also parsed lazily and since we delegate to the "native"
request, it depends on the underlying runtime whether synchronization
is needed. This commit adds synchronization for the HttpServletRequest.
At present RxNetty, Reactor, and Undertow implementations provide
thread-safe access to cookies.
This commit introduces support for running multiple HttpHandler's under
distinct context paths which effectively allows running multiple
applications on the same server. ContextPathIntegrationTests contains
an example of two applications with different context paths.
In order to support this the HttpHandler adapters for all supported
runtimes now have a common base class HttpHandlerAdapterSupport
which has two constructor choices -- one with a single HttpHandler and
another with a Map<String, HttpHandler>.
Note that in addition to the contextPath under which an HttpHandler is
configured there may also be a "native" contextPath under which the
native runtime adapter is configured (e.g. Servlet containers). In such
cases the contextPath is a combination of the native contextPath and
the contextPath assigned to the HttpHandler. See for example
HttpHandlerAdapterSupportTests.

This commit adds a bodyToMono and bodyToFlux convenience method to
ClientResponse/ServerRequest, similar to the body(Publisher) method that
is on ClientRequest/ServerResponse.
This commit introduces the following changes to web.reactive.function:
- Added RouterFunction.andRoute(), a combination of RouterFunction.and()
with RouterFunctions.route()
- ServerRequest.pathVariable() returns String instead of
Optional<String>. An exception is thrown if the variable is not present.
- Added HandlerFilterFunction.andThen and HandlerFilterFunction.apply()
This commit removes the usage of Reactor adapters (about to
be moved from Reactor Core to a new Reactor Adapter module).
Instead, RxReactiveStreams is now used for adapting RxJava
1 and Flowable methods are used for RxJava 2.
Issue: SPR-14824
This commit changes web.reactive.function to reflect the introduction of
the new WebClient. Changes include:
- Request -> ServerRequest
- Response -> ServerResponse
- FilterFunction -> HandlerFilterFunction
- StrategiesSupplier -> HandlerStrategies
This commit refactors the web client to be more similar to
web.reactive.function. Changes include:
- Refactor ClientWebRequest to immutable ClientRequest with builder and
support for BodyInserters.
- Introduce ClientResponse which exposes headers, status, and support
for reading from the body with BodyExtractors.
- Removed ResponseErrorHandler, in favor of having a ClientResponse
with "error" status code (i.e. 4xx or 5xx). Also removed
WebClientException and subclasses.
- Refactored WebClientConfig to WebClientStrategies.
- Refactored ClientHttpRequestInterceptor to ExchangeFilterFunction.
- Removed ClientWebRequestPostProcessor in favor of
ExchangeFilterFunction, which allows for asynchronous execution.
Issue: SPR-14827
This commit moves the web.reactive.function.[BodyInserter|BodyExtractor]
to http.codec, so that they can be used from the client as well.
Furthermore, it parameterized both inserter and extractor over
ReactiveHttpOutputMessage and ReactiveHttpInputMessage respectively, so
that they can be limited to only be used on the client or server.
Typically the Mono<Void> from the HttpHandler also reflects the
completion of the request and response body processors and at that
point invoking AsyncContext#complete() from HandlerResultSubscriber
should be sufficient.
This commit explicitly propagates the AsyncListener.onComplete event
to the request and response body processors for added safety.
Technically as mentioned those processors should have completed but
depending on how the controller is written there is a possibility
the body processors may not have completed.

ServerWebExchange now has a getPrincipal method and along with that a
ServerWebExchangeDecorator that can be used to wrap the exchange in
order to return the authenticated user.
Issue: SPR-14680
The documentation mentions various NativeJdbcExtractors that no longer
exist. To be specific CommonsDbcpNativeJdbcExtractor and
XAPoolNativeJdbcExtractor no longer exist.
This commit includes the following changes:
* remove CommonsDbcpNativeJdbcExtractor references from Asciidoctor
* remove CommonsDbcpNativeJdbcExtractor references from Javadoc
* remove XAPoolNativeJdbcExtractor references from Asciidoctor
Issue: SPR-14810
Closes gh-1205
String with version 5 the name of Java Platform, Enterprise Edition
changed from J2EE to Java EE. However a lot of the documentation still
uses the term J2EE.
This commit includes the following changes:
* replace J2EE with Java EE where appropriate
This is not a blind search and replace. The following occurrences
remain unchanged:
* references to old J2EE releases, most notably 1.3 and 1.4.
* references to "Expert One-On-One J2EE Design and Development"
* references to "Core J2EE patterns"
* XML namespaces
* package names

This commit improves the existing web reactive configuration
infrastructure with the following changes:
* renamed `WebReactiveConfiguration` to
`WebReactiveConfigurationSupport` and is is no longer a Configuration
class
* created the `WebReactiveConfigurer` interface; Configuration classes
implementing it will augment the web reactive configuration support
* created the `DelegatingWebReactiveConfiguration` and
`WebReactiveConfigurerComposite` to effectively tie those custom-defined
configurers to the main configuration support
* created the `@EnableWebReactive` to active that support in
configuration classes
Issue: SPR-14754
Now that OracleLobHandler has finally been removed it should also be
removed from the documentation.
This commit includes the following changes:
* remove OracleLobHandler references from Javadoc
* remove OracleLobHandler references from Asciidoctor
Issue: SPR-14809
Closes gh-1204
