This commit introduces automatic registration of a runtime hint for
classpath resources configured via the `value` attribute in
@WebAppConfiguration.
Closes gh-29026
This commit provides an alternative
java.beans.Introspector#findCustomizerClass implementation
via a GraalVM substitution that avoids to include thousands
of unused AWT classes in the native image.
Closes gh-29060
This commit introduces support for Netty 5's Buffer, in the form of
Netty5DataBuffer. Because of the new API offered by Buffer, several
changes have been made to the DataBuffer API:
- CloseableDataBuffer is a simpler alternative to PooledDataBuffer, and
implemented by Netty5DataBuffer. DataBufferUtils::release can now
handle CloseableDataBuffer as well as PooledDataBuffer.
- PooledDataBuffer::touch has been moved into a separate interface:
TouchableDataBuffer, which is implemented by Netty5DataBuffer.
- The capacity of DataBuffers can no longer be reduced, they can only
grow larger. As a consequence, DataBuffer::capacity(int) has been
deprecated, but ensureWritable (formally ensureCapacity) still exists.
- DataBuffer::slice and retainedSlice have been deprecated in favor of
split, a new method that ensures that memory regions do not overlap.
- DataBuffer::asByteBuffer has been deprecated in favor of toByteBuffer,
a new method that returns a copy, instead of shared data.
- DataBufferFactory::allocateBuffer has been deprecated in favor of
allocateBuffer(int).
Closes gh-28874
This commit introduces the TestClassScanner which scans provided
classpath roots for Spring integration test classes using the JUnit
Platform Launcher API which allows all registered TestEngines to
discover tests according to their own rules.
The scanner currently detects the following categories of Spring
integration test classes.
- JUnit Jupiter: classes that register the SpringExtension via
@ExtendWith.
- JUnit 4: classes that register the SpringJUnit4ClassRunner or
SpringRunner via @RunWith.
- Generic: classes that are annotated with @ContextConfiguration or
@BootstrapWith.
The scanner has been tested with the following TestEngine
implementations for the JUnit Platform.
- JUnit Jupiter
- JUnit Vintage
- JUnit Platform Suite Engine
- TestNG Engine for the JUnit Platform
Closes gh-28824
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.
Closes: gh-28714
This commit adds the supporting testing infrastructure using the
`RuntimeHintsAgent`. Given that the agent is loaded by the JVM running
the test suite, we can then use it to record method invocations at
runtime and check whether the prepared `RuntimeHints` match the expected
behavior.
This commit contributes the `RuntimeHintsRecorder`. With this, we can
record relevant method invocations for a given lambda, focusing on a
specific part of the code behavior. This returns a
`RuntimeHintsInvocations` instance, which is an AssertJ assert provider.
From there, we can perform assertions on the recorded invocations and
check that a given collection of hints cover the reflection, resources
and proxies needs at runtime.
This also ships the `@EnabledIfRuntimeHintsAgent` opinionated
annotation: this applies the `RuntimeHintsAgentCondition` JUnit
extension that detects whether the `RuntimeHintsAgent` is loaded by the
current JVM. Tests annotated with this will be skipped if the agent is
not present. This annotation is also tagged with a JUnit `@Tag` to
gather such tests in a specific `"RuntimeHintsTests"` test suite.
In the Spring Framework build, we have chosen to isolate such tests and
not load the agent for the main test suite ("RuntimeHintsTests" tests
are excluded from the main suite). While the agent's intent is to be as
transparent as possible, there are security and access considerations
that could interefere with other tests.
With this approach, we can then create a separate test suite and run
agent tests in a dedicated JVM.
Note that projects using this infrastructure can choose to use the
condition by itself in a custom annotation.
Here is an example of this testing infrastructure:
```
@EnabledIfRuntimeHintsAgent
class MyTestCases {
@Test
void hintsForMethodsReflectionShouldMatch() {
RuntimeHints hints = new RuntimeHints();
hints.reflection().registerType(String.class,
hint -> hint.withMembers(MemberCategory.INTROSPECT_PUBLIC_METHODS));
RuntimeHintsInvocations invocations = RuntimeHintsRecorder.record(() -> {
Method[] methods = String.class.getMethods();
});
assertThat(invocations).match(hints);
}
}
```

Ideally one would pass WebClient directly to HttpServiceProxyFactory,
but two need to remain decoupled. This commit adds static, shortcut
methods to WebClientAdapter to create an HttpServiceProxyFactory, thus
eliminating the step to wrap the WebClient.
