Use a callback to detect token authentication (via inteceptor) thus
avoiding a potential race between that detection after the message is
sent on the inbound channel (via Executor) and the processing of the
CONNECTED frame returned from the broker on the outbound channel.

Improve the performance of `FormContentFilter` by checking directly if
`contentType` is empty. This saves the need for an exception to thrown
then immediately caught.
Closes gh-23216
Update `MimeTypeUtils` so that the StringUtils.hasLength check is
performed immediately on the incoming argument, rather than in
`parseMimeTypeInternal`. This restores the `IllegalArgumentException`
rather than the `NullPointerException` which is thrown by the
`ConcurrentHashMap`.

Commit 5008423408 added support for
multipart/* media types in FormHttpMessageConverter, but users still had
to manually register multipart/mixed as a supported media type in order
to POST multipart data with that content type.
This commit removes the need to manually register multipart/mixed as a
supported media type by registering it automatically in
FormHttpMessageConverter. In addition, this commit introduces
MULTIPART_MIXED and MULTIPART_MIXED_VALUE constants in MediaType.
Closes gh-23209
This commit improves the cache implementation by skipping the ordering
of most recently used cached keys when the cache is at least half empty.
See gh-23211
As of gh-22340, `MimeTypeUtils` has a built-in LRU cache implementation
for caching parsed MIME types and avoiding excessive garbage creation at
runtime.
This implementation, when hit with highly concurrent reads on the same
media type (the cache key), can create multiple keys for the same MIME
type string. This duplication leads to the cache filling up and evicting
entries. When the cache fetches a duplicate key, it is then not
associated with a value and the cache can return a `null` value, which
is forbidden by the API contract.
This commit adds another cache check within the write lock: this avoids
creating duplicate entries in the cache and `null` return values.
Fixes gh-23211
The responding side now relies on a new MetadataExtractor which decodes
metadata entries of interest, and adds them to an output map whose
values are then added as Message headers, and are hence accessible to
controller methods.
Decoded metadata entry values can be added to the output map one for
one, or translated to any number of values (e.g. JSON properties),
as long as one of the resulting pairs has a key called "route".
On the requesting side, now any metadata can be sent, and a String
route for example is not required to be provided explicitly. Instead
an application could create any metadata (e.g. JSON properties) as long
as the server can work out the route from it.
The commit contains further refinements on the requesting side so that
any mime type can be used, not only composite or routing metadata, e.g.
a route in an "text/plain" entry.
Closes gh-23157
Prior to this commit, the Basic Authentication credentials were encoded
for each request.
This commit addresses this minor performance issue by caching the
encoded credentials in BasicAuthenticationInterceptor.
In addition, this commit introduces new encodeBasicAuth() and
setBasicAuth(String encodedCredentials) methods in HttpHeaders to
support this feature.
Closes gh-23204
Prior to this commit, RestTemplate posted multipart with Content-Type
"multipart/form-data" even if the FormHttpMessageConverter configured
in the RestTemplate had been configured to support additional multipart
subtypes. This made it impossible to POST form data using a content
type such as "multipart/mixed" or "multipart/related".
This commit addresses this issue by updating FormHttpMessageConverter
to support custom multipart subtypes for writing form data.
For example, the following use case is now supported.
MediaType multipartMixed = new MediaType("multipart", "mixed");
restTemplate.getMessageConverters().stream()
.filter(FormHttpMessageConverter.class::isInstance)
.map(FormHttpMessageConverter.class::cast)
.findFirst()
.orElseThrow(() ->
new IllegalStateException("Failed to find FormHttpMessageConverter"))
.addSupportedMediaTypes(multipartMixed);
MultiValueMap<String, Object> parts = new LinkedMultiValueMap<>();
parts.add("field 1", "value 1");
parts.add("file", new ClassPathResource("myFile.jpg"));
HttpHeaders requestHeaders = new HttpHeaders();
requestHeaders.setContentType(multipartMixed);
HttpEntity<MultiValueMap<String, Object>> requestEntity =
new HttpEntity<>(parts, requestHeaders);
restTemplate.postForLocation("https://example.com/myFileUpload", requestEntity);
Closes gh-23159
This commit changes the new addSupportedMediaType(MediaType) method
to addSupportedMediaTypes(MediaType...), in order to allow registration
of multiple supported media types simultaneously.
See gh-23203
Prior to this commit, it was unclear that an invocation of getCache()
might potentially create a new Cache.
This commit updates the Javadoc to point out that concrete CacheManager
implementations may choose to create a new Cache at runtime if the Cache
does not already exist.
Closes gh-23193
This commit clarifies the semantics of the PriorityOrdered interface
with respect to sorting sets of objects containing both PriorityOrdered
and plain Ordered objects.
Closes gh-23187
Prior to this commit, all clients of
ControllerAdviceBean.findAnnotatedBeans() sorted the returned list
manually. In addition, clients within the core Spring Framework
unnecessarily used AnnotationAwareOrderComparator instead of
OrderComparator to sort the list.
This commit presorts the ControllerAdviceBean list using OrderComparator
directly within ControllerAdviceBean.findAnnotatedBeans().
Closes gh-23188
Prior to this commit, there would be no easy way to register client
RSocket handlers against an `RSocketRequester` instance. The only
solution was to gather all handlers and wrap them in a
`RSocketMessageHandler` and configure it as an acceptor on the client
RSocket.
This commit adds a convenience method on the `RSocketRequester` builder
to tkae care of this part of the infrastructure.
