Prior to this commit, the SseBuilder API in WebMvc.fn would only allow
to send Server-Sent Events with `data:` items in them. The spec doesnn't
disallow this and other specifications rely on such patterns to signal
the completion of a stream, like:
```
event:next
data:some data
event:complete
```
This commit adds a new `send()` method without any argument that sends
the buffered content (id, event comment and retry) without data.
Fixes: gh-32270
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
Fix another instance where a LinkedHashMap was initialized with an initial
capacity that would always cause a resize / rehash to occur. Switch to
CollectionUtils.newLinkedHashMap to size the map appropiately for the expected
number of items.
Closes gh-32215
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
ServletAttributesMap inherited default implementations of the size
and isEmpty methods from AbstractMap which delegates to the Set returned
by entrySet. ServletAttributesMap's entrySet method made this fairly
expensive, since it would copy the attributes to a List, then use a
Stream to build the Set. To avoid the cost, add implementations of
isEmpty / size that don't need to call entrySet at all.
Additionally, change entrySet to return a Set view that simply lazily
delegates to the underlying servlet request for iteration.
Closes gh-32189
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`.
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
See gh-32049
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
ResponseEntityExceptionHandler should not set the exception attribute
when there is a response body, and the response is fully handled.
Closes gh-31541
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
This commit makes sure to resolve placeholders in request mappings
using the EmbeddedValueResolver of the current WebApplicationContext.
To avoid retrieving the context too often, we check for the presence of
the standard placeholder prefix.
Closes gh-26795
Prior to this commit, the `HandlerMappingIntrospector` would comparea
request with a cached request by using `String#matches` on their String
URI. This could lead to `PatternSyntaxException` exceptions at runtime
if the request URI contained pattern characters.
This commit fixes this typo to use `String#equals` instead.
Fixes gh-31937
