This commit disables support for evaluating SpEL expressions from
untrusted sources by default. Specifically, this applies to the
SpEL-based 'selector' header support in WebSocket messaging, which
includes the DefaultSubscriptionRegistry and the classes used to
configure the 'selector' header name (SimpleBrokerMessageHandler and
SimpleBrokerRegistration).
The selector header support remains in place but will have to be
explicitly enabled beginning with Spring Framework 6.1.
For example, a custom implementation of WebSocketMessageBrokerConfigurer
can override the configureMessageBroker() method and configure the
selector header name as follows.
registry.enableSimpleBroker().setSelectorHeaderName("selector");
Closes gh-30550
This commit refactors some AssertJ assertions into more idiomatic and
readable ones. Using the dedicated assertion instead of a generic one
will produce more meaningful error messages.
For instance, consider collection size:
```
// expected: 5 but was: 2
assertThat(collection.size()).equals(5);
// Expected size: 5 but was: 2 in: [1, 2]
assertThat(collection).hasSize(5);
```
Closes gh-30104
This commit deprecates ListenableFuture in favor of CompletableFuture.
ListenableFuture was introduced in Spring Framework 4.0, when
CompletableFuture was not yet available. Spring now requires JDK 17, so
having our own type no longer seems necessary.
Major changes in this commit include:
- Deprecation of ListenableFuture and related types
(ListenableFutureCallback, SettableListenableFuture, etc.)
- Deprecation of AsyncListenableTaskExecutor in favor of default methods
in AsyncTaskExecutor (submitCompletable).
- AsyncHandlerMethodReturnValueHandler now has toCompletableFuture
instead of toListenableFuture.
- WebSocketClient now has execute methods, which do the same as
doHandshake, but return CompletableFutures (cf. the reactive
WebSocketClient).
All other changes
- add an overloaded method that takes a CompletableFuture parameter
instead of ListenableFuture, and/or
- add a method with a 'Async' suffix that returns a CompletableFuture
instead of a ListenableFuture (connectAsync, sendAsync).
Closes gh-27780
SockJsServiceRegistration#setSupressCors name contains a typo. It is
now deprecated in favor of a correctly spelled method, setSuppressCors.
See gh-28853
This commit deprecates all methods in org.springframework.scheduling
that use
- Date, in favor of variants that take an Instant.
- long & TimeUnit, in favor of variants that take a Duration.

This commit contains changes made because of the introduction of
HttpStatusCode. In general, methods that used to return a HttpStatus
now return HttpStatusCode instead, and methods that returned raw status
codes are now deprecated.
