This commit adds support for the "Partitioned" cookie attribute in
WebFlux servers and the related testing infrastructure.
Note, Undertow does not support this feature at the moment.
Closes gh-31454
Prior to this commit, #31870 added support for constraint annotations on
container elements for handler method argument validation. Supporting
this use case:
```
public void addNames(List<@NotEmpty String> names)
```
This commit does the same for `@Valid` annotation:
```
public void addPeople(List<@Valid Person> people)
```
Fixes gh-32964
This commit ensures that the FormHttpMessageConverter no longer supports
reading Maps (just MultiValueMaps). Plain maps are often used to
represent JSON.
See gh-32826
This commit makes several improvements to MultiValueMap:
- asSingleValueMap offers a single-value view (as opposed to the
existing toSingleValueMap, which offers a copy)
- fromSingleValue is a static method that adapts a Map<?,?> to the
MultiValueMap interface
- fromMultiValue is a static method that adapts a Map<?,List<?>> to the
MultiValueMap interface
Closes gh-32832
This commit changes the FormHttpMessageConverter from a
HttpMessageConverter<MultiValueMap<String, ?>> to a
HttpMessageConverter<Map<String, ?>>, so that normal, single-value maps
can also be used as form representation, both for reading and writing.
Closes gh-32826
This commit allows to extend the `ServerHttpObservationFilter` when the
observation scope is opened. This typically allows to add the current
traceId as a response header.
Closes gh-30632
Includes JAXBContext locking revision (avoiding synchronization) and consistent treatment of DocumentBuilderFactory (in terms of caching as well as locking).
Closes gh-32851
Prior to this commit, `@ExceptionHandler` annotated controller methods
could be mapped using the exception type declaration as an annotation
attribute, or as a method parameter.
While such methods support a wide variety of method arguments and return
types, it was not possible to declare the same exception type on
different methods (in the same controller/controller advice).
This commit adds a new `produces` attribute on `@ExceptionHandler`; with
that, applications can vary the HTTP response depending on the exception
type and the requested content-type by the client:
```
@ExceptionHandler(produces = "application/json")
public ResponseEntity<ErrorMessage> handleJson(IllegalArgumentException exc) {
return ResponseEntity.badRequest().body(new ErrorMessage(exc.getMessage(), 42));
}
@ExceptionHandler(produces = "text/html")
public String handle(IllegalArgumentException exc, Model model) {
model.addAttribute("error", new ErrorMessage(exc.getMessage(), 42));
return "errorView";
}
```
This commit implements support in both Spring MVC and Spring WebFlux.
Closes gh-31936
The code was necessary while ForwardedHeaderFilter was deprecated
but still possible to use. When the filter was removed, this code
could have been removed as well.
Prior to this commit, `DataBufferLimitException` would be thrown by
codecs when the request body was too large for the configured buffer
limit. This exception would not be handled by the web infrastructure and
would result in an HTTP 500 server error.
This commit introduces a new `PayloadTooLargeException` type that will
result in an HTTP 413 "Payload too large" response status.
Closes gh-32558
