Prior to this commit, documentation for WebJar support referenced the
webjars-locator artifact; however, Spring now uses the
webjars-locator-core artifact.
This commit updates the documentation to reflect this.
Closes gh-22613
Prior to this commit, the PDF version of the Spring Reference Manual
contained HTML <strong></strong> tags in code examples due to the fact
that Asciidoctor converts bold formatting (i.e., elements wrapped in
`**` or `*`) within source code blocks into HTML tags even for PDF
rendering.
This commit addresses this issue by removing all bold formatting from
example code blocks.
Closes gh-22577
Headings are optimized for how they appear in the left-hand side
navitation menu, with context provided by parent headings, and not
necessarily for how they read on their own.
At 2nd and 3rd level of nesting, which is where most headings are,
the wrapping becomes too distracting and the left-hand side navigation
sprawling.
I edited for spelling, puncutation, grammar, usage, and corporate voice. I also added a bunch of cross-references and links to the Javadoc.
I also corrected the rendering problems that I had accidentally created in previous commits (because I was adjusting headings and adding callouts to listings.
1. Rename globalResources to useGlobalResources.
2. Use of global resources is mutually exlusive with explicit config.
3. Allow Consumer<HttpResources> to configure global resources.
4. Allow ConnectionProvider + LoopResources Supplier to customize
creation and initialization.
5. Do not manage externally provided ConnectionProvider + LoopResources
instances.

JettyResourceFactory, similar to ReactorResourceFactory, allows
to share resources (Executor, ByteBufferPool, Scheduler) between
Jetty clients and servers.

This commit handles "empty" cases for `ResponseEntity` controller
handler return types when wrapped with a `java.util.Optional` in Spring
MVC or a single `Publisher` like `Mono`.
Given the following example for Spring MVC:
```
@GetMapping("/user")
public Optional<ResponseEntity<User>> fetchUser() {
Optional<User> user = //...
return user.map(ResponseEntity::ok);
}
```
If the resulting `Optional` is empty, Spring MVC will infer a
`ResponseEntity` with an empty body and a 404 HTTP response status.
The same reasoning is applied to Spring WebFlux with Publisher types:
```
@GetMapping("/user")
public Mono<ResponseEntity<User>> fetchUser() {
Mono<User> user = //...
return user.map(ResponseEntity::ok);
}
```
This feature is only valid for `HttpEntity` return types and does not
apply to `@ResponseBody` controller handlers.

Rename "Builder" sub-section to "Configuration" and move it in the
beginning before all others since it explains how to create a client
in the first place.
Update content on Reactor Netty connector based on the API in 0.8 and
specifically address Reactor Netty resources and lifecycle.
Issue: SPR-16963
Forwarded headers are now processed before ServerWebExchange is created
through ForwardedHeaderTransformer which has the same logic as the
ForwardedHeaderFilter but works on the request only.
ForwardedHeaderFilter is deprecated as of 5.1 but if registered it is
removed from the list of filters and ForwardedHeaderTransformer is used
instead.
Issue: SPR-17072
This commit introduces Protobuf support in WebFlux via dedicated
codecs.
Flux<Message> are serialized/deserialized using delimited Protobuf
messages with the size of each message specified before the message
itself. In that case, a "delimited=true" parameter is added to the
content type.
Mono<Message> are expected to use regular Protobuf message
format (without the size prepended before the message).
Related HttpMessageReader/Writer are automatically registered when the
"com.google.protobuf:protobuf-java" library is detected in the classpath,
and can be customized easily if needed via CodecConfigurer, for example
to specify protocol extensions via the ExtensionRegistry based
constructors.
Both "application/x-protobuf" and "application/octet-stream" mime types
are supported.

1. Revise @SubscribeMapping to address common points of confusion.
2. Add ExecutorSubsribableChannel.
3. Split Events and Interception in two.
Issue: SPR-16950
After the latest changes, two small fixes in the clone method to copy
the encode flag, and in the encodeUriTemplate method to account for
possible null query params.
Improvements in the URI encoding section.

Leverage https://github.com/jetty-project/jetty-reactive-httpclient
to add support for Jetty in WebClient via JettyClientHttpConnector.
Implemented with buffer copy instead of optimized buffer wrapping
because the latter hangs since Callback#succeeded doesn't allow
releasing the buffer and requesting more data at different times
(required for Mono<DataBuffer> for example).
See https://github.com/eclipse/jetty.project/issues/2429.
Issue: SPR-15092
This commit adds FormContentFilter, which is the same as the
HttpPutFormContentFilter but also supports DELETE.
The HttpPutFormContentFilter is now deprecated.
Issue: SPR-16874
The new EncodedResourceResolver is a generalized version of
GzipResourceResolver that can be configured to support different
content codings, by "br" and "gzip".
GzipResourceResolver is now deprecated.

This commit makes it possible to pass attributes from the WebSession of
a handshake request to the WebSocketSession, by configuring a
Predicate<String> on HandshakeWebSocketService.
Issue: SPR-16212
This commit removes all places where forwarded headers are checked
implicitly, on an ad-hoc basis.
ForwardedHeaderFilter is expected to be used instead providing
centralized control over using or discarding such headers.
Issue: SPR-16668
1. Consistent with "xml code" examples.
2. "xml()" is a static method and will use default builder config,
so use createXmlMapper(true) instead.
3. Fix mvc namespace tag typo.
This commit restructures the existing content to separate out Overview
content into its own section, and also introduces more formal structure
where reference type content can be expanded over time.

We cover this more succinctly from other places, e.g. in Model Methods
by referring to the Javadoc of Contentions, or pointing to the
RequestToViewNameTranslator.
@EnableWebFlux bootstraps both annotated controllers and functional
endpoints, so we need to be more explicit about which parts of the
configuration apply to which.
Issue: SPR-16360
This commit allows CorsConfiguration#combine()
to differentiate permit default values set by
CorsConfiguration#applyPermitDefaultValues()
from values configured explicitly by the user.
Those permit default values will be overridden
by any user-provided ones while user-provided values
will be combined in an additive way, including
when "*" is specified.
Documentation has been improved accordingly.
Issue: SPR-15772
- Add "Processing" section (also replaces Advanced Customizations)
- Add information on out-of-the-box behavior
- Add more deails on @CrossOririn default configuratio
- Add cross-references between Spring MVC and WebFlux
- Polish
Access-Control-Allow-Credentials CORS header, used to
allow cookies with CORS requests, is not set to true
anymore by default when enabling CORS with
@CrossOrigin or global CORS configuration in order to
provide a more secured default CORS configuration.
The related allowCredentials property now requires to
be set to true explicitly in order to support cookies
with CORS requests.
Issue: SPR-16130
This commit introduces a new AbstractReactiveWebInitializer in
spring-web that relies on WebHttpHandlerBuilder to detect request
processing infrastructure beans from an ApplicationContext.
This eliminates the need to create a DispatcherHandler, since it is
expected to be a Spring bean, and as a result the initializers in
spring-webflux have been deprecated.
Issue: SPR-16144
A new HTTP/2 support section has been added in the Spring MVC
documentation. Also, a dedicated wiki page is created for specific
container support information.
