This binary format more efficient than JSON should be useful for server
to server communication, for example in micro-services use cases.

This commit introduces an apply method to `WebClient.Builder`, allowing
users to make multiple changes to the builder in one consumer.
Issue: SPR-15743
The failures look like older failures possibly exposed by recent
changes in Reactor.
The one in ViewResolutionResultHandler is very old test error.
The one in Jackson2JsonDecoderTests is more recent but went unreported.
This commit moves `toEntity(Class<T>)` and `toEntityList(Class<T>)`
from WebClient.ResponseSpec to ClientResponse. The main reason for doing
so is that the newly introduced `onStatus` method (see
2f9bd6e075) does not apply to these two
methods, and the result would be confusing. Also, `ClientResponse` and
`ResponseEntity` represent the same data: status code, headers, and a
body.
Issue: SPR-15724
This commit introduces a way to customize the WebClientExceptions, as
thrown by WebClient.ResponseSpec.bodyTo[Mono|Flux]. The first
customization will override the defaults, additional customizations are
simply tried in order.

This commit changes `ServerRequest.attribute(String)`` to return
`Optional<Object>` instead of `Optional<T>`, where `T` was infered
from a type parameter.
Explicitly pass the client-side JSR-356 WebSocketContainer to the
TomcatWebSocketClient to prevent the ContainerProvider from finding
the one from undertow-websockets-jsr through the ServiceLoader API.
This commit disables the "failOnServerError" feature on the
`HttpClientRequest`, as wrapped by ReactorClientHttpRequest. 5xx errors
are supposed to be dealt with in the WebClient, not in the lower-level
components.
Issue: SPR-15739
This commit introduces client-side request attributes, similar to those
found on the server-side. The attributes can be used, for instance, for
passing on request-specific information to a globally registered
ExchangeFilterFunction.
The client request builder, as well as WebClient.RequestHeadersSpec and
WebTestClient.RequestHeaderSpec, add methods for adding a single
attribute, as well as manipulating the entire attributes map.
The client request itself adds a accessor for the (immutable) attributes
map.
This commit also introduces a new variant of the basic authentication
filter in ExchangeFilterFunctions. This variant takes the username and
password from well-known attributes.
Issue: SPR-15691
This commit changes ServerRequest.queryParams from returning a
List<String> given a String name, to returning a
MultiValueMap<String, String>, which gives more flexibility.
This commit uses the newly introduced `PathContainer` and `RequestPath`
support in the functional web framework. It exposes the path container
as property in `ServerRequest`, and uses that in the path-based
`RequestPredicates`.
Direct comparison of a pattern (as a String) to the path does not make
much sense now that we deal with URL encoding through PathContainer
which exposes (safely) decoded path segments.
Removing the PathPatternComparator also means we can keep patterns
pre-sorted instead of sorting them all the time. That probably offsets
any benefits from comparing to the lookup path for direct matches and
patterns are still sorted according to specificity.
This commits extends nullability declarations to the field level, formalizing the interaction between methods and their underlying fields and therefore avoiding any nullability mismatch.
Issue: SPR-15720
This commit adds support for Void response body types in the WebClient,
both when using `exchange` with a response.bodyToMono(Void.class), as
well as using `retrieve` with `toEntity(Void.class)`.
Issue: SPR-15679
This commit replaces the WebClient.filter method with
WebClient.Builder.filter. The reason for this change is that filters
added via WebClient.filter would be applied in the opposite order of
their declaration, due to the compositional nature of the method,
combined with the immutable nature of the WebClient.
WebClient.Builder.filter does keep the order of the filters, as
registered.
Furthermore, this commit introduces a WebClient.mutate() method,
returning a WebClient.Builder. This method allow to add/remove filters
and other defaults from a given WebClient.
Issue: SPR-15657
Add WebClient.Builder.addFilter
Add Consumer-based headers and cookies methods to builders.
Add WebClient.mutate
This commit changes the `ExchangeStrategies` and `HandlerStrategies`
interfaces to consistently use the `CodecConfigurer` (and
sub-interfaces) for configuring codecs on the server and on the client.
Issue: SPR-15682
Supporting ScriptEngine#eval(String, Bindings) when no render function
is specified allows to support use cases where script templates are
simply evaluating a script expression with an even more simplified
configuration.
This improvement also makes it possible to use script engines that
do not implement Invocable.
Issue: SPR-15115
This commit introduces LocaleContextResolver interface, which is used
at ServerWebExchange level to resolve Locale, TimeZone and other i18n
related informations.
It follows Spring MVC locale resolution patterns with a few differences:
- Only LocaleContextResolver is supported since LocaleResolver is less
flexible
- Support is implemented in the org.springframework.web.server.i18n
package of spring-web module rather than in spring-webflux in order
to be able to leverage it at ServerWebExchange level
2 implementations are provided:
- FixedLocaleContextResolver
- AcceptHeaderLocaleContextResolver
It can be configured with both functional or annotation-based APIs.
Issue: SPR-15036
Previously `HandlerMapping` implementation were heavily relying on
`String` path patterns, `PathMatcher` implementations and dedicated maps
for matching incoming request URL to an actual request handler.
This commit adds the `PathPatternRegistry` that holds `PathPattern`
instances and the associated request handler — matching results are then
shared as `PathMatchResult` instances. `AbstractUrlHandlerMapping` will
use this registry directly, but other components dealing with request
matching (like `PatternsRequestCondition`) will directly use ordered
`PathPattern` collections since ordering is important there.
This opens the door for faster request matching and simplifies the
design of this part.
Issue: SPR-15608
This commit removes the headers(HttpHeaders) method on ClientRequest and
ServerResponse, in favor of headers(Consumer<HttpHeaders>), which is
more flexible.
The revised builder emphasizes creating a list of resolvers either
built-in or custom with each top-level builder method resulting in
adding a resolver.
By default only the Header resolver is configured.
The path extension resolver is removed altogether to discourage its use
but is trivial to create manually with the helpf of
UriUtils#extractFileExtension + MediaTypeFactory.
