Prior to this commit some of the default strategies defined
for the DispatcherServlet weren't included in the default
configuration for both Java and XML configuration.
The following default beans have been added to the configuration
with the name as expected by the DispatcherServlet:
- org.springframework.web.servlet.i18n.AcceptHeaderLocaleResolver
- org.springframework.web.servlet.theme.FixedThemeResolver
- org.springframework.web.servlet.support.SessionFlashMapManager
- org.springframework.web.servlet.view.DefaultRequestToViewNameTranslator
Closes gh-25209
Prior to this commit, the `VersionResourceResolver` implementations
would write a strong ETag HTTP response header with the resolved version
of the resource (the actual value depending on the chosen strategy).
This approach doesn't work well when combined with HTTP compression.
Web servers disable HTTP response copression in the presence of strong
ETags since mutating the response body would break the contract.
This commit changes this semantic and ensures that weak ETags are used
instead.
Closes gh-24898
This commit adds the checkNotModified method to ServerRequest in both
WebFlux.fn and WebMvc.fn. Unlike other checkNotModified methods found
in the framework, this method does not return a boolean, but rather
a response wrapped in a Mono/Optional. If the resource has
not been changed, the not-modified response can be returned directly;
if the resource has changed, the user can create a corresponding
response using switchIfEmpty/orElse(Get).
Closes gh-24173
These calls were added in error when trying to fix#22797 and #23775.
They are not needed in 304 scenarios. Those have no response content and
are skipped by ShallowETagHeaderFilter based on the status.
This leaves disableContentCaching invoked only in streaming scenarios,
which was the original intent and should be the only reason for that
method.

This commit deprecates PathExtensionContentNegotiationStrategy and
ServletPathExtensionContentNegotiationStrategy and also updates code
that depends on them internally to remove that dependence.
See gh-24179
This commit updates CORS support in order to check Origin header
in CorsUtils#isPreFlightRequest which does not change how Spring
MVC or WebFlux process CORS request but is more correct in term
of behavior since it is a public API potentially used in another
contexts.
It also removes an unnecessary check in
AbstractHandlerMethodMapping#hasCorsConfigurationSource and processes
every preflight request with PreFlightHandler.
Closes gh-24327
When a request is mapped through a producible condition on an
@RequestMapping, then a failure to find a converter/decoder should be
a 500 because the return type + media type pair were declared by the
controller and that should be possible to render.
Closes gh-23287
This commit restores the interpretation of JSON as UTF-8 by default that
was removed in #bc205e0 and also ensures a charset is not appended
automatically to "application/json".
Closes gh-24123
