In Spring Framework 7.1, the TestContext Framework will reliably detect
all default context configuration within the type hierarchy or
enclosing class hierarchy (for @Nested test classes) above a given
test class; however, test suites may encounter failures once we make
that switch in behavior.
In order to help development teams prepare for the switch in 7.1, this
commit logs a warning similar to the following whenever default context
configuration is detected but currently ignored.
WARN - For test class [org.example.MyTests$NestedTests], the
following 'default' context configuration classes were detected but
are currently ignored: org.example.MyTests$Config. In Spring
Framework 7.1, these classes will no longer be ignored. Please update
your test configuration accordingly. For details, see:
https://docs.spring.io/spring-framework/reference/testing/testcontext-framework/ctx-management/default-config.html

The methods to build a request in RestClientAdapter and WebClientAdapter
are now public to make it easier to create a custom adapter that wraps
the built-in ones and delegates for methods that can be the same.
Closes gh-36374
Prior to this commit, flush calls on the output stream returned by
`ServletServerHttpResponse#getBody` would be delegated to the Servlet
response output stream.
This can cause performance issues when `HttpMessageConverter` and other
web components write and flush multiple times to the response body.
Here, the Servlet container is in a better position to flush to the
network at the optimal time and buffer the response body until then.
This is particularly true for `HttpMessageConverters` when they flush
many times the output stream, sometimes due to the underlying codec
library. Instead of revisiting the entire message converter contract, we
are here ignoring flush calls to that output stream.
This change does not affect the client side, nor the
`ServletServerHttpResponse#flush` calls.
This commit also introduces a new Spring property
`"spring.http.response.flush.enabled"` that reverts this behavior change
if necessary.
Closes gh-36385
This commit adapts RuntimeHints to be compatible with v1.2.0 of the
GraalVM metadata format. The changes are as follows:
* Resources and resource bundles are now defined at the same level. This
is transparent to users.
* Serialization is no longer a top-level concept, but rather an
attribute of a type or proxy. The top-level concept has been deprecated
and the relevant methods have been added.
Closes gh-36379
Prior to this commit, a few implementations of the `HttpMessageConverter`
contract were inheriting from abstract classes. Those classes were
performing extra `OutputStream#flush` on the response body even though
this is the responsibility of the super class. Such abstract classes
do flush already, after delegating to the `writeInternal` method.
This commit ensures that we remove such extra calls as they tend to
waste resources for no added benefit.
Closes gh-36383
This commit updates the target type detection in
`ResourceHttpMessageConverter` to only support target types that are
relevant: `InputStreamResource` for streaming, and types assignable from
`ByteArrayResource` for non-streaming cases.
Closes gh-36368
The `AbstractMessageConverterMethodProcessor` is in charge of handling
controller method return values and to write those as HTTP response
messages. The content negotiation process is an important part.
The `MimeTypeUtils#sortBySpecificity` is in charge of sorting inbound
"Accept" media types by their specificity and reject them if the list
is too large, in order to protect the application from ddos attacks.
Prior to this commit, the content negotiation process would first get
the sorted "Accept" media types, the producible media types as
advertized by message converters - and collect the intersection of both
in a new list (also sorted by specificity). If the "Accept" list is
large enough (but under the limit), the list of compatible media types
could exceed that limit because duplicates could be introduced in that
list: several converters can produce the same content type.
This commit ensures that compatible media types are collected in a set
to avoid duplicates. Without that, exceeding the limit at this point
will throw an `InvalidMimeTypeException` that's not handled by the
processor and result in a server error.
