This is the orginal "A bean is an object that is instantiated, assembled, and otherwise managed by a Spring IoC container". Here's an extra word of "otherwise".
This commit adds a new `StartupStep` interface and its factory
`ApplicationStartup`. Such steps are created, tagged with metadata and
thir execution time can be recorded - in order to collect metrics about
the application startup.
The default implementation is a "no-op" variant and has no side-effect.
Other implementations can record and collect events in a dedicated
metrics system or profiling tools. We provide here an implementation for
recording and storing steps with Java Flight Recorder.
This commit also instruments the Spring application context to gather
metrics about various phases of the application context, such as:
* context refresh phase
* bean definition registry post-processing
* bean factory post-processing
* beans instantiation and post-processing
Third part libraries involved in the Spring application context can
reuse the same infrastructure to record similar metrics.
Closes gh-24878
Prior to this commit, The "auto grow" feature in SpEL expressions only
worked for element types with a default constructor. For example, auto
grow did not work for a list of BigDecimal elements.
This commit inserts a null value in the list when no default
constructor can be found for the element type.
Closes gh-25367
Because of security and broader industry support, support for several
remoting technologies is now deprecated and scheduled for removal in
Spring Framework 6.0.
This commit deprecates the following remoting technologies:
* HTTPInvoker
* RMI
* Hessian
* JMS remoting
Other remoting technologies like EJB or JAXWS might be deprecated in the
future depending on industry support.
Closes gh-25379
This commit introduces support for R2DBC ("Reactive Relational Database
Connectivity") with custom ConnectionFactory implementations, a
functional DatabaseClient for SQL execution, transaction management, a
bind marker abstraction database initialization utilities, and
exception translation.
Closes gh-25065
This commit introduces a change in reactive transaction semantics for
cancel signals. Canceling a subscription now rolls back a reactive transaction
to achieve a deterministic transaction outcome.
Previously, cancel signals committed a transaction which could
cause partially committed transactions depending on when the cancel happened.
Prior to this commit (and the previous one), the `AntPathStringMatcher`
(inner class of `AntPathmatcher`) would compile `Pattern` instances and
use regex matching even for static patterns such as `"/home"`.
This change introduces a shortcut in the string matcher algorithm to
skip the `Pattern` creation and uses `String` equality instead.
Static patterns are quite common in applications and this change can
bring performance improvements, depending on the mix of patterns
configured in the web application.
In benchmarks (added with this commit), we're seeing +20% throughput
and -40% allocation. This of course can vary depending on the number of
static patterns configured in the application.
Closes gh-24887
Prior to this commit, the Spring Framework test suite would rely only on
"Performance" tests associated with a specific CI build. As outlined in
gh-24830, the way they're built and executed is not working well
anymore.
This commit introduces a new JMH benchmark infrastructure in the build.
The goal here is not to run those benchmarks as part of a CI build, but
rather provide a proper infrastructure for writing and locally running
micro-benchmarks when working on specific optimizations.
This commit adds and configures a Gradle JMH plugin to allow for JMH
benchmark classes in Spring Framework modules (in `src/jmh/java` of each
`spring-*` module). It's also relaxing the checkstyle rules for JMH
classes, especially around Javadoc rules: this code is not meant to
have Javadocs.
Finally, this commit links to a new Wiki page on the project GitHub
repository documenting the infrastructure and helping contributors to
run and design benchmarks.
See gh-24830
TransactionAttribute now exposes a labels attribute that associates a
descriptive array of labels with a transaction.
Labels may be of a pure descriptive nature or may get evaluated by
transaction managers to associate technology-specific behavior
with the actual transaction.
This commit introduces support for setting the
spring.test.constructor.autowire.mode property via a JUnit Platform
configuration parameter -- for example, via the
junit-platform.properties file.
Closes gh-24285
Since the spring-framework.png file is not used in the generated
reference manual, this commit moves the spring-framework.png file from
the src/docs/asciidoc/images folder up to the src/docs folder.
As of gh-24952, `PathPatternParser` will strictly reject patterns with
`"**"` in the middle of them. `"**"` is only allowed at the end of the
pattern for matching multiple path segments until the end of the path.
Currently, if `"**"` is used in the middle of a pattern it will be
considered as a single `"*"` instead. Rejecting such cases should
clarify the situation.
This commit prepares for that upcoming change and:
* logs a warning message if such a case is used by an application
* expands the MVC and WebFlux documentation about URI matching in
general
Closes gh-24958
Prior to this commit, it was unclear in the documentation that a default
constructor will be used by default for autowiring if multiple
constructors are present and none of them is annotated with @Autowired.
This commit improves the documentation in this regard.
Closes gh-24838
This commit adds a section to the reference docs that explains
views live within the trust boundary of the application, and the
security implications thereof.
Closes gh-24777
This commit fixes the example by reverting the renaming of the local
Actor variable to avoid a conflict with a same-named variable already
in the current scope.
See gh-24398
0.4.0 provides built-in support for remembering a user's selections
using local storage. This replaces the custom switch language
JavaScript.
The selection is stored using a key derived from the
options that were available. Concretely, when the options are Java or
Kotlin, the local storage key is java-kotlin. Similarly, if the
choices were Java, Kotlin, and XML, the key would be java-kotlin-xml.
Given local storage's domain and protocol scoping, the nature of the
key that's used for storage will allow a user's selections to be
applied across all documentation hosted on https://docs.spring.io that
offer the same options.
Closes gh-24481
This commit deprecates PathExtensionContentNegotiationStrategy and
ServletPathExtensionContentNegotiationStrategy and also updates code
that depends on them internally to remove that dependence.
See gh-24179
Using Consumer<ClientCodecConfigurer> instead of
Consumer<ExchangeStrategies> eliminates one level of nesting that is
also unnecessary since codecs are the only strategy at present.
Closes gh-24124
As a follow-up of gh-23961, this change provides a way for custom codecs
to align with the default codecs' behavior on common features like
buffer size limits and logging request details.
Closes gh-24118

Prior to this commit, developers could configure their WebClient to use
their custom `ExchangeStrategies`, by providing it in the
`WebClient.Builder` chain.
Once created, an `ExchangeStrategies` instance is not mutable, which
makes it hard for further customizations by other components. In the
case of the reported issue, other components would override the default
configuration for the codecs maxInMemorySize.
This commit makes the `ExchangeStrategies` mutable and uses that fact to
further customize them with a new `WebClient.Builder#exchangeStrategies`
`Consumer` variant. This commit is also deprecating those mutating
variants in favor of a new `WebClient.Builder#exchangeStrategies` that
takes a `ExchangeStrategies#Builder` directly and avoids mutation issues
altogether.

Before this change an @MessageMapping could be matched to any RSocket
interaction type, which is arguably too flexible, makes it difficult to
reason what would happen in case of a significant mismatch of
cardinality, e.g. request for Fire-And-Forget (1-to-0) mapped to a
method that returns Flux, and could result in payloads being ignored,
or not seen unintentionally.
This commit checks @ConnectMapping method on startup and rejects them
if they return any values (sync or async). It also refines each
@MessageMapping to match only the RSocket interaction type it fits
based on the input and output cardinality of the handler method.
Subsequently if a request is not matched, we'll do a second search to
identify partial matches (by route only) and raise a helpful error that
explains which interaction type is actually supported.
The reference docs has been updated to explain the options.
Closes gh-23999
Previously, spring-webmvc and spring-webflux both contained tests
that would create gzipped files, write them to the filesystem
alongside the project's compiled test classes, and configure them to
be deleted on JVM exit. The output location placed the files on the
classpath, polluting it for every subsequent test that used the same
ClassLoader. The test-sources plugin combined with Gradle's use of
worker JVMs, broadens the scope of this pollution to other, downstream
projects in the same build. For example, the tests for
spring-websocket will have a different classpath depending on whether
or not the tests for spring-webmvc have already been run on the same
worker as part of the current build.
This commit updates the spring-webmvc and spring-webflux modules to
introduce a new JUnit Jupiter extension, GzipSupport. This extension
allows gzipped files to be created via an injectable GzippedFiles
class and automatically deletes each created file in an after-each
callback. This ensures that a gzipped file only exists on the
classpath for the duration of the test that needs it, avoiding the
pollution of the classpath of any subsequent tests.
Closes gh-23970
Commit 979508a7f3 removed the JUnit 4
dependency from all modules except spring-test. Unfortunately, the
@Inject TCK tests (SpringAtInjectTckTests) are still based on JUnit 3.
Thus, that commit accidentally excluded those tests from the build.
This commit includes SpringAtInjectTckTests in the build again by
introducing a test runtime dependency on the JUnit Vintage TestEngine
in spring-context.
See gh-23451
As a follow-up of gh-22915, the purpose of this commit is to improve
Coroutines programmatic transaction API to make it more consistent with
the Java one and more idiomatic.
For suspending functions, this commit changes the
TransactionalOperator.transactional extension with a suspending lambda
parameter to a TransactionalOperator.executeAndAwait one which is
conceptually closer to TransactionalOperator.execute Java API so more
consistent.
For Flow, the TransactionalOperator.transactional extension is correct
but would be more idiomatic as a Flow extension.
This commit also adds code samples to the reference documentation.
Closes gh-23627
Prior to this commit, a lot of work had been done to prevent improper
use of testing Framework APIs throughout the codebase; however, there
were still some loopholes.
This commit addresses these loopholes by introducing additional
Checkstyle rules (and modifying existing rules) to prevent improper use
of testing framework APIs in production code as well as in test code.
- Checkstyle rules for banned imports have been refactored into
multiple rules specific to JUnit 3, JUnit 4, JUnit Jupiter, and
TestNG.
- Accidental usage of org.junit.Assume has been switched to
org.junit.jupiter.api.Assumptions.
- All test classes now reside under org.springframework packages.
- All test classes (including abstract test classes) now conform to the
`*Tests` naming convention.
- As an added bonus, tests in the renamed
ScenariosForSpringSecurityExpressionTests are now included in the
build.
- Dead JUnit 4 parameterized code has been removed from
DefaultServerWebExchangeCheckNotModifiedTests.
Closes gh-22962
This commit adds Coroutines extensions for
TransactionalOperator.transactional that accept suspending lambda or
Kotlin Flow parameters.
@Transactional on suspending functions is not supported yet, gh-23575
has been created for that purpose.
Closes gh-22915
This commit moves the dependency management and test source files
related to integration tests to a dedicated module.
This allows us to focus the root project on building the Spring
Framework.
See gh-23282
Add `SpringJUnit5` checkstyle rule to ensure that JUnit 4 annotations
aren't accidentally used in new tests.
The "must not be public" rule has been suppressed since there are
quite a few tests that extend base tests from other packages.
This commit introduces Kotlin code snippets, for now
in the core reference documentation. Other sections
will follow, as well as improvements like global
language switch.
See gh-21778
Prior to this commit, the SimpleUrlHandlerMapping classes in Spring MVC
and Spring Webflux only had default constructors. This lead to the fact
that users often had to explicitly invoke setUrlMap() and setOrder() on
the newly instantiated SimpleUrlHandlerMapping.
In order to simplify the programmatic setup of a SimpleUrlHandlerMapping
in common scenarios, this commit introduces the following constructors.
- SimpleUrlHandlerMapping()
- SimpleUrlHandlerMapping(Map<String, ?> urlMap)
- SimpleUrlHandlerMapping(Map<String, ?> urlMap, int order)
Closes gh-23362
gh-23289 introduced support for multiple single-line comment prefixes
for ScriptUtils, ResourceDatabasePopulator, and EmbeddedDatabaseBuilder.
This commit adds the same support for @SqlConfig in the TestContext
Framework. Specifically, @SqlConfig has a new `commentPrefixes`
attribute for setting multiple single-line comment prefixes.
Closes gh-23331
Replace docs on using MultipartBodyBuilder for the RestTemplate with
examples that show MultiValueMap. Originally the idea was to make
MultipartBodyBuilder accessible to the RestTemplate too, but with
support for async parts that's no longer a good fit.
Closes gh-23295
Prior to this commit, there was some ambiguity surrounding semantics
for @Autowired constructors and `required = true`, especially for
multiple @Autowired constructors.
This commit improves the documentation in the Javadoc for @Autowired as
well as in the reference manual.
Closes gh-23263
Prior to this commit, @TestConstructor supported a boolean `autowire`
attribute which naturally limited the configuration to two states: on
or off. Since we may need to support additional autowiring modes in the
future, the use of a boolean is limiting.
This commit address this issue by introducing a new AutowireMode enum
in @TestConstructor with ALL and ANNOTATED constants. In addition, the
attribute has been renamed to `autowireMode`, and the system property
has been renamed to `spring.test.constructor.autowire.mode` for greater
clarity of purpose.
Closes gh-23224
The commit deprecates syncBody(Object) in favor of body(Object)
which has the same behavior in ServerResponse, WebClient and
WebTestClient. It also adds body(Object, Class) and
body(Object, ParameterizedTypeReference) methods in order to support
any reactive type that can be adapted to a Publisher via
ReactiveAdapterRegistry. Related BodyInserters#fromProducer
methods are provided as well.
Shadowed Kotlin body<T>() extensions are deprecated in favor of
bodyWithType<T>() ones, including dedicated Publisher<T> and
Flow<T> variants. Coroutines extensions are adapted as well, and
body(Object) can now be used with suspending functions.
Closes gh-23212
Prior to this commit, RestTemplate posted multipart with Content-Type
"multipart/form-data" even if the FormHttpMessageConverter configured
in the RestTemplate had been configured to support additional multipart
subtypes. This made it impossible to POST form data using a content
type such as "multipart/mixed" or "multipart/related".
This commit addresses this issue by updating FormHttpMessageConverter
to support custom multipart subtypes for writing form data.
For example, the following use case is now supported.
MediaType multipartMixed = new MediaType("multipart", "mixed");
restTemplate.getMessageConverters().stream()
.filter(FormHttpMessageConverter.class::isInstance)
.map(FormHttpMessageConverter.class::cast)
.findFirst()
.orElseThrow(() ->
new IllegalStateException("Failed to find FormHttpMessageConverter"))
.addSupportedMediaTypes(multipartMixed);
MultiValueMap<String, Object> parts = new LinkedMultiValueMap<>();
parts.add("field 1", "value 1");
parts.add("file", new ClassPathResource("myFile.jpg"));
HttpHeaders requestHeaders = new HttpHeaders();
requestHeaders.setContentType(multipartMixed);
HttpEntity<MultiValueMap<String, Object>> requestEntity =
new HttpEntity<>(parts, requestHeaders);
restTemplate.postForLocation("https://example.com/myFileUpload", requestEntity);
