Prior to this commit, `@ExceptionHandler` annotated controller methods
could be mapped using the exception type declaration as an annotation
attribute, or as a method parameter.
While such methods support a wide variety of method arguments and return
types, it was not possible to declare the same exception type on
different methods (in the same controller/controller advice).
This commit adds a new `produces` attribute on `@ExceptionHandler`; with
that, applications can vary the HTTP response depending on the exception
type and the requested content-type by the client:
```
@ExceptionHandler(produces = "application/json")
public ResponseEntity<ErrorMessage> handleJson(IllegalArgumentException exc) {
return ResponseEntity.badRequest().body(new ErrorMessage(exc.getMessage(), 42));
}
@ExceptionHandler(produces = "text/html")
public String handle(IllegalArgumentException exc, Model model) {
model.addAttribute("error", new ErrorMessage(exc.getMessage(), 42));
return "errorView";
}
```
This commit implements support in both Spring MVC and Spring WebFlux.

Prior to this commit, DynamicPropertyRegistry could only be used with a
static @DynamicPropertySource method in an integration test class;
however, it can also be useful to be able to register a "dynamic
property" from within a test's ApplicationContext -- for example, in a
@Bean method in a @Configuration class that is specific to testing
scenarios.
To support such use cases, this commit updates the dynamic property
source infrastructure so that a DynamicPropertyRegistry is always
registered as a singleton bean in a test's ApplicationContext. This
allows DynamicPropertyRegistry to be autowired into a @Configuration
class or supplied to a @Bean method as an argument as shown in the
following example.
@Bean
@DynamicPropertySource
ApiServer apiServer(DynamicPropertyRegistry registry) {
ApiServer apiServer = new ApiServer();
registry.add("api.url", apiServer::getUrl);
return apiServer;
}
Note that the use of @DynamicPropertySource on the @Bean method is
optional and results in the corresponding bean being eagerly
initialized so that other singleton beans in the context can be given
access to the dynamic properties sourced from that bean when those
other beans are initialized.
Side note: DynamicPropertySourceBeanInitializer temporarily implements
LoadTimeWeaverAware since doing so is currently the only way to have a
component eagerly initialized before the
ConfigurableListableBeanFactory.preInstantiateSingletons() phase.
However, we plan to introduce a first-class callback to support such
use cases in the future.
Closes gh-32271
This change switches default behavior of `@TestBean`, `@MockitoBean` and
`@MockitoSpyBean` to match the bean definition / bean to override by
type in the case there is no explicit bean name provided via the
annotation. The previous behavior of using the annotated field's name
is still an option for implementors, but no longer the default.
Closes gh-32761
This change splits the documentation in the reference manual: the
`@TestBean`, `@MockitoBean` and `@MockitoSpyBean` annotations are kept
in the appendix and the general documentation about the feature is moved
into a dedicated sub-section of the TCF section.

Prior to this commit, the text `#{ }` was displayed as { } with a bright
green background.
This commit addresses this by making use of Asciidoc's literal monospace
feature: `+#{ }+`.
This commit improves on the bean overriding feature in several ways:
the API is simplified and polished (metadata and processor contracts,
etc...).
The commit also reworks infrastructure classes (context customizer,
test execution listener, BeanOverrideBeanFactoryPostProcessor, etc...).
Parsing of annotations is now fully stateless.
In order to avoid OverrideMetadata in bean definition and to make a
first step towards AOT support, the BeanOverrideBeanFactoryPostProcessor
now delegates to a BeanOverrideRegistrar to track classes to parse,
the metadata-related state as well as for the field injection methods
for tests.
Lastly, this commit increases the test coverage for the provided
annotations and adds integration tests and fixes a few `@TestBean`
issues.
This commit makes the use of bean definition overriding more visible and
prepare for a deprecation of the feature in the next major release.
As of this commit, use of bean definition overriding logs at INFO level.
The previous log level can be restored by setting the
allowBeanDefinitionOverriding flag explicitly on the BeanFactory (or
via the related ApplicationContext).
A number of tests that are using bean overriding on purpose have been
updated to set this flag, which will make them easier to find once we
actually deprecate the feature.
Closes gh-31288
The ApplicationContext has a resource cache that it uses while the
context is being refreshed. Once the refresh phase completes, the
cache is cleared as its content is no longer in use. If beans are
lazily initialized, there is a case where the cache might be filled
again as processing is deferred past the refresh phase.
For those cases, the cache is not cleared. This can be a problem when
running in this mode with a large set of test configurations as the TCF
caches the related contexts.
This commit includes an additional TestExecutionListener to the TCF that
clears the resource cache if necessary once a test class completes. It
is ordered so that it runs after `@DirtiesContext` support as marking
the context as dirty will remove it from the cache and make that extra
step unnecessary.
Closes gh-30954
This commit upgrades to a major new release of HtmlUnit. This is a
breaking change as HtmlUnit 3 moves to a `org.htmlunit` package and
calling code needs to be restructured.
Our use of Selenium has been adapted accordingly, moving to Selenium
3, using the new org.seleniumhq.selenium:htmlunit3-driver integration.
Closes gh-30392
This commit introduces two sets of annotations (`@TestBean` on one side
and `MockitoBean`/`MockitoSpyBean` on the other side), as well as an
extension mecanism based on the `@BeanOverride` meta-annotation.
Extension implementors are expected to only provide an annotation,
a BeanOverrideProcessor implementation and an OverrideMetadata subclass.
Closes gh-29917.
Includes rollbackOn annotation attribute on @EnableTransactionManagement and addDefaultRollbackRule method on AnnotationTransactionAttributeSource, as well as publicMethodsOnly as instance-level flag (also on AnnotationCacheOperationSource).
