Prior to this commit (and since Spring Framework 5.0), Spring's
integration with JUnit Jupiter supported detection of test
configuration (e.g., @ContextConfiguration, etc.) on @Nested classes.
However, if a @Nested class did not declare its own test configuration,
Spring would not find the configuration from the enclosing class. This
is in contrast to Spring's support for automatic inheritance of test
configuration from superclasses. The only workaround was to
copy-n-paste the entire annotation configuration from enclosing classes
to nested tests classes, which is cumbersome and error prone.
This commit introduces a new @NestedTestConfiguration annotation that
allows one to choose the EnclosingConfiguration mode that Spring should
use when searching for test configuration on a @Nested test class.
Currently, the options are INHERIT or OVERRIDE, where the current
default is OVERRIDE. Note, however, that the default mode will be
changed to INHERIT in a subsequent commit. In addition, support will be
added to configure the global default mode via the SpringProperties
mechanism in order to allow development teams to revert to the behavior
prior to Spring Framework 5.3.
As of this commit, inheritance of the following annotations is honored
when the EnclosingConfiguration mode is INHERIT.
- @ContextConfiguration / @ContextHierarchy
- @ActiveProfiles
- @TestPropertySource / @TestPropertySources
- @WebAppConfiguration
- @TestConstructor
- @BootstrapWith
- @TestExecutionListeners
- @DirtiesContext
- @Transactional
- @Rollback / @Commit
This commit does NOT include support for inheriting the following
annotations on enclosing classes.
- @Sql / @SqlConfig / @SqlGroup
In order to implement this feature, the search algorithms in
MetaAnnotationUtils (and various other spring-test internals) have been
enhanced to detect when annotations should be looked up on enclosing
classes. Other parts of the ecosystem may find the new
searchEnclosingClass() method in MetaAnnotationUtils useful to provide
similar support.
As a side effect of the changes in this commit, validation of user
configuration in repeated @TestPropertySource declarations has been
removed, but this may be reintroduced at a later date.

This commit adds support for Kotlin Coroutines suspending functions to
Spring MVC, by converting those to a Mono that can then be handled by
the asynchronous request processing feature.
It also optimizes Coroutines detection with the introduction of an
optimized KotlinDetector.isSuspendingFunction() method that does not
require kotlin-reflect.
Closes gh-23611
Flow decoding is not supported yet since it depends on
kotlin/kotlinx.serialization#1073, but it will be
enabled when this issue will be fixed.
Closes gh-25771
The workaround was removed in the 5.3 milestone phase and in master
only because the referenced Jetty issue is marked fixed. However,
what we need to replace it with should be a little more involved
and also it's not entirely clear if the fixes in Jetty aligns with
our release and retain semantics so that needs to be investigated
more thoroughly.
Prior to this commit, the resource handler serving static resources for
Spring MVC and Spring WebFlux would always look at the
`Resource#lastModified` information, derive the `"Last-Modified"` HTTP
response header and support HTTP conditional requests with that
information.
In some cases, builds or packaging tools choose to set this last
modification date to a static date in the past. This allows tools to
have reproducible builds or to leverage caching given the static
resources content didn't change.
This can lead to problems where this static date (e.g. "1980-01-01") is
used literally in HTTP responses and will make the HTTP caching
mechanism counter-productive: the content of the resources changed, but
the application insists on saying it didn't change since the 80s...
This commit adds a new configuration option to disable this support -
there is no way to automatically discard those dates: there is no
standard for that and many don't use he "EPOCH 0 date" as it can lead to
compatibility issues with different OSes.
Closes gh-25845
Prior to this commit, error handlers in the WebMvc.fn and WebFlux.fn
router function builders had to be registered in an unintuitive, reverse
order, due to the filter chain composition model used.
This commit reverses the error handler order, so that more specific
error handlers can come before generic ones.
Closes gh-25541
This commit adds two overloaded methods for each HTTP method in the
WebFlux.fn and WebMvc.fn route builders: one method taking just a
handler function, the other a request predicate and handler function.
After this commit, it is no longer required to provide a String path,
which is particularly useful when nesting routes, and the path would be
"".
Closes gh-25752
This commit introduces a new async(Object) method in the WebMvc.fn,
taking a asynchronous response as argument in the form of a
CompletableFuture or Publisher. This allows for asynchronous setting
of headers and status (and not just body, which was already possible).
Closes gh-25828
