1. Update the HandlerMapping contract to state that CORS checks are expected
to be applied before returning a handler.
2. DispatcherHandler checks explicitly for pre-flight requests or CORS failed
requests and skips handling for both. Technically no change since
AbstractHandlerMapping already returns a NO_OP_HANDLER for those cases.
The purpose however is for the DispatcherHandler to also guarantee more
explicitly that no such handling can take place for such cases.
As one consequence, this makes it possible to invoke the DispatcherHandler from
anywhere in the WebFilter chain in order to "handle" a pre-flight request, and
then skip the rest of the WebFilter chain.
See gh-26257
The alternative is to use a filter but this makes it a little easier
and also guarantees that it will be downstream from all filters
regardless of their order, and therefore the Context will be visible
to all of them.

This commit makes copies of the default headers and cookies when a
WebClient is built, so that subsequent changes to these do not affect
previously built clients.
Closes: gh-25992
Allow the body to be written in order for all headers to be set
as they would be on HTTP GET. The body content is ignored as a
lower level.

The migration from JUnit 4 assertions to AssertJ assertions resulted in
several unnecessary casts from int to long that actually cause
assertions to pass when they should otherwise fail.
This commit fixes all such bugs for the pattern `.isNotEqualTo((long)`.
Prior to this commit, the resource handler serving static resources for
Spring MVC and Spring WebFlux would always look at the
`Resource#lastModified` information, derive the `"Last-Modified"` HTTP
response header and support HTTP conditional requests with that
information.
In some cases, builds or packaging tools choose to set this last
modification date to a static date in the past. This allows tools to
have reproducible builds or to leverage caching given the static
resources content didn't change.
This can lead to problems where this static date (e.g. "1980-01-01") is
used literally in HTTP responses and will make the HTTP caching
mechanism counter-productive: the content of the resources changed, but
the application insists on saying it didn't change since the 80s...
This commit adds a new configuration option to disable this support -
there is no way to automatically discard those dates: there is no
standard for that and many don't use he "EPOCH 0 date" as it can lead to
compatibility issues with different OSes.
Closes gh-25845
Prior to this commit, error handlers in the WebMvc.fn and WebFlux.fn
router function builders had to be registered in an unintuitive, reverse
order, due to the filter chain composition model used.
This commit reverses the error handler order, so that more specific
error handlers can come before generic ones.
Closes gh-25541
The exchange() method is now deprecated because it is not safe for
general use but that doesn't apply to the WebTestClient because it
exposes a different higher level API for response handling that
ensures the response is consumed. Nevertheless WebTestClient cannot
call WebClient.exchange() any more.
To fix this WebTestClient no longer delegates to WebClient and thus
gains direct access to the underlying ExchangeFunction. This is
not a big deal because WebClient and WebTestClient do the same
only when it comes to gathering builder options and request input.
See gh-25751
This commit makes sure that exceptions emitted by WebClient are wrapped
by WebClientExceptions:
- Exceptions emitted by the ClientHttpConnector are wrapped in a new
WebClientRequestException.
- Exceptions emitted after a response is received are wrapped in a
WebClientResponseException
Closes gh-23842
This commit makes several changes in both WebMvc.fn as well as
WebFlux.fn.
- ServerRequest now exposes a RequestPath through requestPath(), and
pathContainer() has been deprecated.
- The PathPredicate and PathResourceLookupFunction now respects this
RequestPath's pathInApplication() in their path-related
functionality.
- When nesting, the PathPredicate now appends the matched part of the
path to the current context path, instead of removing the matched
part (which was done previously). This has the same result: the
matched part is gone, but now the full path stays the same.
Closes gh-25270
Remove convenience Map that is to avoid. The only downside is that
getHandlerMethods requires a transformation but that should not be used frequently.
See gh-22961
