Prior to this commit, `MockMvc` would support checking for the Servlet
error message as the "response status reason". While this error message
can be driven with the `@ResponseStatus` annotation, this message is not
technically the HTTP status reason listed on the response status line.
This message is provided by the Servlet container in the error page when
the `response.sendError(int, String)` method is used.
This commit adds the missing
`mvc.get().uri("/error/message")).hasErrorMessage("error message")`
assertion to check for this Servlet error message.

Prior to this commit, information was logged when a bean definition
overrode an existing bean definition, but nothing was logged when the
registration of a bean definition resulted in the removal of an alias.
With this commit, an INFO message is now logged whenever an alias is
removed in DefaultListableBeanFactory.
Closes gh-34070
This commit fixes a regression introduced by gh-24560, when adding
execution metadata support for scheduled tasks. The
`OutcomeTrackingRunnable` would delegate to the actual runnable but
could also hide whether it implements the `SchedulingAwareRunnable`
contract.
This commit ensures that `OutcomeTrackingRunnable` always implements
that contract and delegates to the runnable if possible, or return
default values otherwise.
Fixes gh-34058
Properly processes recursive types through always comparing generics via the top-level ResolvableType (rather than through nested TypeDescriptors with custom ResolvableType instances).

It is currently possible for one Bean Override to override another
logically equivalent Bean Override.
For example, a @TestBean can override a @MockitoBean, and vice versa.
In fact, it's also possible for a @MockitoBean to override another
@MockitoBean, for a @TestBean to override a @TestBean, etc.
However, there may be viable use cases for one override overriding
another override. For example, one may have a need to spy on a bean
created by a @TestBean factory method.
In light of that, we do not prohibit one Bean Override from overriding
another Bean Override; however, with this commit we now log a warning
to help developers diagnose issues in case such an override is
unintentional.
For example, given the following test class, where TestConfig registers
a single bean of type MyService named "myService"...
@SpringJUnitConfig(TestConfig.class)
class MyTests {
@TestBean(methodName = "example.TestUtils#createMyService")
MyService testService;
@MockitoBean
MyService mockService;
@Test
void test() {
// ...
}
}
... running that test class results in a log message similar to the
following, which has been formatted for readability.
WARN - Bean with name 'myService' was overridden by multiple handlers:
[
[TestBeanOverrideHandler@44b21f9f
field = example.MyService example.MyTests.testService,
beanType = example.MyService,
beanName = [null],
strategy = REPLACE_OR_CREATE
],
[MockitoBeanOverrideHandler@7ee8130e
field = example.MyService example.MyTests.mockService,
beanType = example.MyService,
beanName = [null],
strategy = REPLACE_OR_CREATE,
reset = AFTER,
extraInterfaces = set[[empty]],
answers = RETURNS_DEFAULTS, serializable = false
]
]
NOTE: The last registered BeanOverrideHandler wins. In the above
example, that means that @MockitoBean overrides @TestBean, resulting
in a Mockito mock for the MyService bean in the test's
ApplicationContext.
Closes gh-34056
Prior to this commit, the Bean Override feature in the Spring
TestContext Framework (for annotations such as @MockitoBean and
@TestBean) silently allowed one bean override to override another
"identical" bean override; however, Spring Boot's @MockBean and
@SpyBean support preemptively rejects identical overrides and throws
an IllegalStateException to signal the configuration error to the user.
To align with the behavior of @MockBean and @SpyBean in Spring Boot,
and to help developers avoid scenarios that are potentially confusing
or difficult to debug, this commit rejects identical bean overrides in
the Spring TestContext Framework.
Note, however, that it is still possible for a bean override to
override a logically equivalent bean override. For example, a
@TestBean can override a @MockitoBean, and vice versa.
Closes gh-34054
This metadata information is required for supporting libraries using
`sun.misc.Unsafe#allocateInstance(Class<?>)`, even though Spring
Framework is not using this feature.
Closes gh-34055
To make an analogy to read phenomena for transactional databases, this
commit effectively fixes the "Phantom Read" problem for Bean Overrides.
A phantom read occurs when the BeanOverrideBeanFactoryPostProcessor
retrieves a set of bean names by-type twice and a new bean definition
for a compatible type has been created in the BeanFactory by a
BeanOverrideHandler between the first and second retrieval.

Prior to this commit, the injection of test Bean Overrides (for
example, when using @MockitoBean) could fail in certain scenarios if
overrides were created for nonexistent beans "by type" without an
explicit name or qualifier. Specifically, if an override for a SubType
was created first, and subsequently an attempt was made to create an
override for a SuperType (where SubType extends SuperType), the
override for the SuperType would "override the override" for the
SubType, effectively removing the override for the SubType.
Consequently, injection of the override instance into the SubType field
would fail with an error message similar to the following.
BeanNotOfRequiredTypeException: Bean named 'Subtype#0' is expected to
be of type 'Subtype' but was actually of type 'Supertype$Mock$XHb7Aspo'
This commit addresses this issue by tracking all generated bean names
(in a generatedBeanNames set) and ensuring that a new bean override
instance is created for the current BeanOverrideHandler if a previous
BeanOverrideHandler already created a bean override instance that now
matches the type required by the current BeanOverrideHandler.
In other words, if the generatedBeanNames set already contains the
beanName that we just found by-type, we cannot "override the override",
because we would lose one of the overrides. Instead, we must create a
new override for the current handler. In the example given above, we
must end up with overrides for both SuperType and SubType.
Closes gh-34025
This commit restores the user class in generated RootBeanDefinition
instances. Previously the CGLIB subclass was exposed. While this is
important in regular runtime as the configuration class parser operates
on the bean definition, this is not relevant for AOT as this information
is internal and captured in the instance supplier.
