Prior to this commit, the `StandardWebSocketUpgradeStrategy` would get
the HTTP headers from the handshake request and store them in the
WebSocket session for the entire duration of the session.
As of gh-36334, Spring MVC manages HTTP directly with a native API
instead of copying them. This improves performance but also uncovered
this bug: we cannot keep a reference to HTTP headers once the HTTP
exchange is finished, because such resources can be recycled and reused.
This commit ensures that the handshake headers are copied into the
session info to keep them around for the entire duration of the session.
Without that, Tomcat will raise an `IllegalStateException` at runtime.
This was already done for WebFlux in SPR-17250, but the latest header
management changes in Framework uncovered this issue for the Standard
WebSocket container case.
Fixes gh-36486
Prior to this commit, Spring web frameworks were using the
"application/x-ndjson" media type for streaming JSON payloads delimited
with newlines.
The "application/jsonl" media type seems to gain popularity in the
broader ecosystem and could supersede NDJSON in the future. This commit
adds support for JSON Lines as an alternative.
Closes gh-36485
Introduces a general-purpose consumeContent method on Resource and EncodedResource with special behavior for multi-content resources. Regular getInputStream/getReader calls will expose the merged content of all same-named resources in the classpath.
Closes gh-36415
Prior to this commit, the `WebTestClient` could only accept non-nullable
types in its `expectBodyList<T>` Kotlin extension function.
This commit relaxes this requirements to allow for more assertions.
Fixes gh-36476
This commit ensures that `ParameterizedTypeReference<T>` can accept
nullable types. This is especially useful for Kotlin extension functions
and assertion contracts.
Fixes gh-36477
Since the Spring Framework uses American English spelling, this commit
updates Javadoc and the reference manual to ensure consistency in that
regard. However, there are two exceptions to this rule that arise due
to their use within a technical context.
- We use "cancelled/cancelling" instead of "canceled/canceling" in
numerous places (including error messages).
- We use "implementor" instead of "implementer".
Closes gh-36470
Prior to this commit, if a superclass or enclosing test class (such as
one annotated with @SpringBootTest or simply
@ExtendWith(SpringExtension.class)) was not annotated with
@ContextConfiguration (or @Import with @SpringBootTest), the
ApplicationContext loaded for a subclass or @Nested test class would
not use any default context configuration for the superclass or
enclosing test class.
Effectively, a default XML configuration file or static nested
@Configuration class for the superclass or enclosing test class was
not discovered by the AbstractTestContextBootstrapper when attempting
to build the MergedContextConfiguration (application context cache key).
To address that, this commit introduces a new
resolveDefaultContextConfigurationAttributes() method in
ContextLoaderUtils which is responsible for creating instances of
ContextConfigurationAttributes for all superclasses and enclosing
classes. This effectively enables AbstractTestContextBootstrapper to
delegate to the resolved SmartContextLoader to properly detect a
default XML configuration file or static nested @Configuration class
even if such classes are not annotated with @ContextConfiguration.
Closes gh-31456
This commit revises the resolveExplicitTestContextBootstrapper()
algorithm in BootstrapUtils to allow a local @BootstrapWith annotation
to override a meta-annotation within the same composed annotation.
Closes gh-35938
This commit apply extra checks to ScriptTemplateView resource handling
with ResourceHandlerUtils, consistently with what is done with static
resource handling.
Closes gh-36458
Restore both WebMVC and WebFlux variants that were deleted
by mistake in commit 4db2f8ea1b.
This commit also removes the empty resource loader path, as it is not
needed for the main WEB-INF/ use case that is typically configured
explicitly by the user, and not needed to pass the restored tests.
Closes gh-36456
Prior to this commit, the `ClassFile` based implementation of
`AnnotationMetadata` would rely on the `NestHost` class element to get
the enclosing class name for a nested class.
This approach works for bytecode emitted by Java11+, which aligns with
our Java17+ runtime policy. But there are cases where bytecode was not
emitted by a Java11+ compiler, such as Kotlin. In this case, the
`NestHost` class element is absent and we should instead use the
`InnerClasses` information to get it.
This commit makes use of `InnerClasses` to get the enclosing class name,
but still uses `NestHost` as a fallback for anonymous classes.
Fixes gh-36451
Uses ClassFileAnnotationMetadata name for actual AnnotationMetadata.
Moves JSR-305 dependency to compile-only for all spring-core tests.
Closes gh-36432
Prior to this commit, the `setMessageConverters` method would have
private visibility. But `initBodyConvertFunction`, which is `protected`,
relies on the message converters being set in the first place.
While this works with `RestTemplate` because this is done automatically,
the `RestClient` does offer a builder method to configure a
`ResponseErrorHandler` and this makes it impossible to configure
converters in this case.
This commit aligns the method visibility by making it protected.
Closes gh-36434
Prior to this commit, our implementation of Server Sent Events (SSE),
`SseEmitter` (MVC) and `ServerSentEvent` (WebFlux), would not guard
against invalid characters if the application mistakenly inserts such
characters in the `id` or `event` types.
Both implementations would also behave differently when it comes
to escaping comment multi-line events.
This commit ensures that both implementations handle multi-line comment
events and reject invalid characters in id/event types.
This commit also optimizes `String` concatenation and memory usage
when writing data.
Fixes gh-36440
