This commit revers the removal of the `private` keyword in the examples
of the reference documentation and the tests for consistency. While the
default visibility makes the example more concise, it could imply to the
reader that the field (or the factory method) cannot be private.
Also, there is no need to multiply anything returned from `Objects.hash`
as its very distinct on its own already.
This commit harmonizes how a candidate bean definition is determined
for overriding using `@TestBean`, `@MockitoBean`, and `@MockitoSpyBean`.
Previously, a qualifier was necessary even if the name of the annotated
field matches the name of a candidate. After this commit, such candidate
will be picked up transparently, the same it is done for regular
autowiring.
This commit also reviews the documentation of the feature as considering
the field means that its name is taken into account to compute a cache
key if by-type lookup is requested.
Closes gh-32939
This commit changes how factory method for `@TestBean` usage is
discovered. Previously the field name or bean name suffixed with
'TestOverride' was used. It sounds more natural to just use the
field name or bean name, leaving cases where a suffix is required
to explicitly providing the method name.
As part of this change, the exception messages have been revisited as
it's less since the method name candidates have the exact same name
as the field or bean name. A `()` is added to make it more clear the
name is for a method.
Closes gh-32940
This commit adds support for Kotlin BeanPostProcessor beans which should
be defined in a companion object and annotated with `@JvmStatic`.
Closes gh-32946
This commit uses the bean factory `isAutowiredCandidate` method directly
in `BeanOverrideBeanFactoryPostProcessor` to select a single match among
multiple candidates when matching by type.
The expected consequence, in most cases, is that this will delegate to
a `@Qualifier`-aware `QualifierAnnotationAutowireCandidateResolver`.
In that sense, bean overriding by-type matching is now potentially
taking Qualifier annotations or meta-annotations into account.
It also changes the way existing bean definitions are checked in case
a bean name has been specified: factory beans are now taken into account
when checking the type of an existing definition matches the expected
bean override type.
Closes gh-32822
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.
Closes gh-31936
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
