This commit introduces new HTTP method, Content-Type, and Accept header
request predicates that handle single values. Previously, these
predicates were always dealt with as single-value collections, which
introduced computational overhead.
Closes gh-32244
Prior to this commit, the `RequestPredicates` would add new attributes
to the existing request attributes by creating a new `LinkedHashMap`
with the total number of elements as its new initial capacity.
This would not achieve optimal performance as initial resize or rehash
operations could be expected. Consistently using
`CollectionUtils#newLinkedHashMap` avoids this problem.
Closes gh-32201
To improve consistency and avoid confusion regarding primitive types
and their wrapper types, this commit ensures that we always use class
literals for primitive types.
For example, instead of using the `Void.TYPE` constant, we now
consistently use `void.class`.
Before this commit, the JDK and Jetty connectors do not have any
safeguards against multiple body subscriptions. Such as check has now
been added.
Closes gh-32100
The behavior for the toString() implementation for annotations changed
in JDK 19, per my request to the JDK team (see link below).
Specifically, since JDK 19, the toString() implementation for annotation
proxies created by the JDK started using canonical names instead of
binary names for types.

This commit revises the RequestMappingHandlerMapping implementations in
Spring MVC and Spring WebFlux to ensure that a @Controller class which
implements an interface annotated with @HttpExchange annotations can
inherit the @HttpExchange declarations from the interface or
optionally override them locally with @HttpExchange or
@RequestMapping annotations.
Closes gh-32065
This commit updates the RequestMappingHandlerMapping implementations in
Spring MVC and Spring WebFlux so that mixed @RequestMapping and
@HttpExchange declarations on the same element are rejected.
Note, however, that a @Controller class which implements an interface
annotated with @HttpExchange annotations can still inherit the
@HttpExchange declarations from the interface or optionally override
them locally with @HttpExchange or @RequestMapping annotations.
See gh-31962

Closes gh-32065
This commit updates the RequestMappingHandlerMapping implementations in
Spring MVC and Spring WebFlux so that multiple @HttpExchange
declarations on the same element are rejected.
Closes gh-32049
If multiple request mapping annotations are discovered, Spring MVC and
Spring WebFlux now log a warning similar to the following (without
newlines).
Multiple @RequestMapping annotations found on
void org.example.MyController.put(), but only the first will be used:
[
@org.springframework.web.bind.annotation.PutMapping(consumes={}, headers={}, name="", params={}, path={"/put"}, produces={}, value={"/put"}),
@org.springframework.web.bind.annotation.PostMapping(consumes={}, headers={}, name="", params={}, path={"/put"}, produces={}, value={"/put"})
]
Closes gh-31962
This commit adds CORS support for Private Network Access
by adding an Access-Control-Allow-Private-Network response
header when the preflight request is sent with an
Access-Control-Request-Private-Network header and that
Private Network Access has been enabled in the CORS
configuration.
See https://developer.chrome.com/blog/private-network-access-preflight/
for more details.
Closes gh-28546
