Prior to this commit, paths configured via the scripts attribute in
@Sql were required to be final paths without dynamic placeholders;
however, being able to make script paths dependent on the current
environment can be useful in certain testing scenarios.
This commit introduces support for property placeholders (${...}) in
@Sql script paths which will be replaced by properties available in
the Environment of the test's ApplicationContext.
Closes gh-33114
Prior to this commit, @TestBean factory methods had to be defined in
the test class, one of its superclasses, or in an implemented
interface. However, users may wish to define common factory methods in
external classes that can be shared easily across multiple test classes
simply by referencing an external method via a fully-qualified method
name.
To address that, this commit introduces support for referencing a
@TestBean factory method via its fully-qualified method name following
the syntax <fully-qualified class name>#<method name>.
Closes gh-33125
Prior to this commit, the "Method Arguments" documentation for WebFlux
in the reference manual stated that WebFlux controller methods can
accept arguments of type Map, Model, or ModelMap to access the model.
However, ModelMap is actually not supported and results in exception
due to a type mismatch.
This commit updates the documentation to reflect this.
In addition, this commit updates related Javadoc and tests to avoid
mentioning or using ModelMap in WebFlux.
Closes gh-33107
Prior to this commit, the comment in the XML configuration example in
the Method Injection section of the reference manual referred to the
wrong bean names.

This commit restructures the section on MockMvc so that the anchors
are easier to read. The standard integration has moved to a
Hamcrest Integration section at the same level as HtmlUnit Integration,
and a new AssertJ Integration section has been created.
Closes gh-32454
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
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).
Closes gh-23473
Prior to this commit, if a Spring Expression Language (SpEL) expression
referenced the root context object via the #root or #this variable, we
inserted a checkcast in the generated byte code that cast the object to
its concrete type. However if the root context object's type was
non-public, that resulted in an IllegalAccessError when the compiled
byte code was executed.
VariableReference.getValueInternal() already contains a solution for
global variables which inserts a checkcast to Object in the generated
byte code instead of to the object's concrete non-public type.
This commit therefore applies the same logic to #root (or #this when
used to reference the root context object) that is already applied to
global variables.
Closes gh-32356
Prior to this commit, the reference manual only documented indexing
support for arrays, lists, and maps.
This commit improves the overall documentation for SpEL's property
navigation and indexing support and introduces additional documentation
for indexing into Strings and Objects.

For consistency with other examples, this commit omits `method` parameter

This commit removes the previous implementation in favor of the new
PlaceholderParser. The only noticeable side effect is that the exception

This commit allows EmbeddedDatabaseConfigurer instances to be further
customized if necessary. EmbeddedDatabaseBuilder has a way now to set
a DatabaseConfigurer rather than just a type to provide full control,
or customize an existing supported database type using the new
EmbeddedDatabaseConfigurers#customizeConfigurer callback.
Closes gh-21160
Although EvaluationContext defines the API for setting and looking up
variables, the internals of the Spring Expression Language (SpEL)
actually provide explicit support for registering functions as
variables.
This is self-evident in the two registerFunction() variants in
StandardEvaluationContext; however, functions can also be registered as
variables when using the SimpleEvaluationContext.
Since custom functions are also viable in use cases involving the
SimpleEvaluationContext, this commit documents that functions may be
registered in a SimpleEvaluationContext via setVariable().
This commit also explicitly documents the "function as a variable"
behavior in the class-level Javadoc for both StandardEvaluationContext
and SimpleEvaluationContext, as well as in the reference manual.
Closes gh-32258
This commit focuses on improving the AOT section on programmatic

As a bit of trivia, Jakarta EL was originally Unified EL, which was
originally JSP EL, which was originally SPEL.
SPEL: Simplest Possible Expression Language
SpEL: Spring Expression Language
So one could say that SPEL inspired SpEL.
