Exclude `@ConfigurationProperties` beans from method validation so
that `@Validated` can be used on final classes without the method
validation post-processor throwing an exception.
This commit introduces a `FilteredMethodValidationPostProcessor` class
which will use `MethodValidationExcludeFilters` to exclude beans from
method validation processing. Using `@EnableConfigurationProperties`
will automatically register an appropriate filter.

Previously, the locale context resolver used with WebFlux could only be
configured by provided a custom LocaleContextResolver bean. By
constrast, when using Spring MVC, the spring.mvc.locale and
spring.mvc.locale-resolver properties could be used to configure the
locale and the resolver (fixed or Accept header) respectively.
This commit introduces spring.web.locale and spring.web.locale-resolver
properties and deprecates their spring.mvc equivalents. The new
properties can be used to configure locale resolution with either
Spring MVC or WebFlux.

Previously, @WebListeners were discovered via custom component scanning
and then registered programmatically via the ServletContext. The servlet
spec requires any ServletContextListener registered in this manner to be
prohibited from programatically configuring servlets, filters, and
listeners. This left us not strictly complying with the servlet spec
as a ServletContextListener registered via a @WebListener annotation
should be able to programatically configure other components.
This commit updates WebListenerHandler to register each @WebListener
component directly with Jetty, Tomcat, or Undertow rather than via the
ServletContext API. This ensure that any @WebListener-annoated
ServletContextListener registered via servlet component scanning is
able to programatically register servlets, filters, and listeners.
There is a small chance that this will be a breaking change for some
users:
1. The ServletListenerRegistrationBeans that were previously defined
for each @WebListener will now be
WebListenerHandler.WebListenerRegistrars
2. Each @WebListener-annotated class will now be instantiated by
Jetty, Tomcat, or Undertow. Jetty and Tomcat both require the class
to be public and have a public default constructor. Previously,
a package-private class or default constructor could be used as the
instantiation was performed by Spring Framework. Undertow is not
affected as it can instantiate a package-private type.

Prior to this commit, the `StaticResourceLocation` for favicons would
point to `"/**/favicon.ico"`. This location does not reflect the current
web development landscape, since the png format and size variants are

and is deprecated by the new path pattern support in Spring Framework
(see gh-22833).

supporting common use cases such as `"/favicon.ico"`, `"/favicon.png"`
and `"/icons/icon-48x48.png"`.

Previously, the default servlet was registered automatically when using
embedded Jetty, Tomcat, or Undertow. However, it is not used by the
majority of applications where Spring MVC's DispatcherServlet will be
the only servlet that's needed. As such configuring the default servlet
was wasting CPU and memory.
This commit changes the default for registering the default servlet to
false. It can be re-enabled by setting
server.servlet.register-default-servlet=true.

Previously, spring.flyway.init-sqls was only applied to Flyway's
configuration if Flyway was being configured to create the DataSource.
If Flyway was being configured to use an existing DataSource, init-sqls
was not applied. This is a hangover from when the init SQLs support was
introduced. At that time, Flyway only supported SQL to initialize the
connection when it was creating the DataSource. Flyway 5.2 added init
SQL support no matter how Flyway's DataSource was configured.
This commit updates FlywayAutoConfiguration to always apply the
init-sqls property to Flyway's configuration. The property's
documentation does not describe the current limitation so this change
should align the behaviour with what the documentation leads people to
expect.

Prior to this commit, Spring Boot would auto-configure both
Elasticsearch variants: `RestClient` ("Low Level" client) and
`RestHighLevelClient` ("High Level" client).
Since one can be derived from the other, this would create complex and
unclear situations depending on what developers provided with their
configuration.
`RestHighLevelClient` is mostly for actual use of the Elasticsearch API,
with support for specific methods and (de)serialization. On the other
hand, `RestClient` is merely wrapping the Apache HTTP client for
load-balancing support and low level HTTP features.
This commit completely removes the support for `RestClient` in Spring
Boot and now requires the presence of the
`org.elasticsearch.client:elasticsearch-rest-high-level-client`
dependency for REST client support with Elasticsearch.

Previous to this commit, an auto-configuration would create a
PlatformTransactionManager if none is present and others conditions are

out-of-the-box. This commit makes sure to back-off if any
TransactionManager is available.

The current arrangement with Neo4j does not allow us to know for sure
that the user intends to use `@Transactional` for reactive or imperative
operations.
The main reason for that is that the only trigger for the reactive
auto-configuration is the presence of reactor on the classpath given
that the Neo4j driver ships with both styles in the same jar. And
reactor can be on the classpath for a number of reasons that are
unrelated to imperative access (typically `WebClient`).
This commits removes the auto-configuration of the
ReactiveNeo4jAutoConfiguration and makes sure that if the user defines
one, the regular `PlatformTransactionManager` backs off. This is
a temporarily situation until we can provide a better signal that the
user intends to primarily use imperative repositories.
Closes gh-22940

`PropertyValue` (and the `BeanWrapper` eventually).
The previous behavior is left as a fallback and without a change in
Spring Framework will continue to be the default for most applications.

With the upgrade to the new Couchbase SDK and the related changes in
Spring Data Couchbase, CacheManagerCustomizer can no longer be used to

update the documentation to refer to it with a sample usage.

Previously, UrlPathHelper's full path optimization was enabled when
there was a dispatcher servlet mapped to /. The UrlPathHelper is used
across Spring MVC and if there are multiple dispatcher servlets they
all share the sample UrlPathHelper. This meant that any additional
dispatcher servlets mapping to locations other than / would not be able
to map requests correctly as the UrlPathHelper would use the full path,
ignoring the url mapping of the dispatcher servlet.
This commit updates the MVC auto-configuration so that use of the full
path is only enabled if there's a single dispatcher servlet
registration.

Previously, background pre-init was started in response to the
application starting event. This meant that it would be running while

As of Spring Framework 5.3, it is now possible to use `PathPatternParser`
to parse and match request mapping path patterns, as an alternative to
the current default `AntPathMatcher`.
This new implementation has been used for a while in Spring WebFlux and
it’s been designed for consistency and performance.
This commit introduces a new configuration property for opting-in this
new variant:
`spring.mvc.pathmatch.matching-strategy=path_pattern_parser`
The default option is still `ant_path_matcher` for now, but we might
change the default in future versions since Spring Framework considers
it the best choice for modern applications.
There are several behavior differences with this new variant:
* double wildcards `"**"` are rejected when used in the middle patterns,
this is only allowed as the last matching segment in a pattern.
* it is incompatible with some path matching options, like
suffix-pattern, registered-suffix-pattern or configuring a Servlet
prefix on the `DispatcherServlet` (`spring.mvc.servlet.path=/test`)

configuration error. A failure analyzer is also provided to improve
diagnostics for common mis-configurations detected by this validation.

Previously, the import selector for `@ImportAutoConfiguration` did not
consider the spring.autoconfigure.exclude property when determining
which auto-configurations to exclude. This meant that tests using a
slice that included a particular auto-configuration would include it
even if the application's configuration excluded it via
spring.autoconfigure.exclude. Confusingly, this could result in a
sliced test using an auto-configuration that would be excluded in a
broader `@SpringBootTest`.
This commit updates the ImportAutoConfigurationImportSelector to
consider the spring.autoconfigure.exclude property so that sliced tests
will use a subset of the auto-configurations that a `@SpringBootTest`
would use.

Since Spring Framework 4.3.0.RC2, a default embedded value resolver
has been registered with the bean factory when one is not otherwise
configured. This meant that placeholders in `@Value` would be resolved
with or without PropertyPlaceholderAutoConfiguration defining a
PropertySourcesPlaceholderConfigurer bean. However, placeholders in
bean definitions would only be resolved if a
PropertySourcesPlaceholderConfigurer was defined.
This commit updates PropertyPlaceholderAutoConfigurationTests to align
with this change in Framework. We now test that placeholders are
resolved in `@Value` annotations with or without the auto-configuration
and that placeholders in bean definitions are only resolved with the
auto-configured.

Previously, LifecycleAutoConfiguration would check the current context

This commit updates the auto-configuration to only check the current
context.

Previously, Spring Boot's modules published Gradle Module Metadata
(GMM) the declared a platform dependency on spring-boot-dependencies.
This provided versions for each module's own dependencies but also had
they unwanted side-effect of pulling in spring-boot-dependencies
constraints which would influence the version of other dependencies
declared in the same configuration. This was undesirable as users
should be able to opt in to this level of dependency management, either
by using the dependency management plugin or by using Gradle's built-in
support via a platform dependency on spring-boot-dependencies.
This commit reworks how Spring Boot's build uses
spring-boot-dependencies and spring-boot-parent to provide its own
dependency management. Configurations that aren't seen by consumers are
configured to extend a dependencyManagement configuration that has an
enforced platform dependency on spring-boot-parent. This enforces
spring-boot-parent's version constraints on Spring Boot's build without
making them visible to consumers. To ensure that the versions that
Spring Boot has been built against are visible to consumers, the
Maven publication that produces pom files and GMM for the published
modules is configured to use the resolved versions from the module's
runtime classpath.

Prior to this commit, the welcome page support implemented in gh-9785
would override existing index views in both annotation and functional
variants.
This comes from the fact that the feature was implemented as a
`RouterFunction` configured in the main `RouterFunctionMapping` bean.
Due to ordering issues between mappings, this would override existing
application mappings in some cases.
This commit ensures that the welcome page `RouterFunction` is
contributed to the context in its own handler mapping, ordered after the
application ones.

Previously, HttpMessageConvertersAutoConfiguration registered
ServerProperties. When this happened in a parent context, any child

bind server.servlet.encoding directly instead of enabling
ServerProperties. With ServerProperties no longer enabled in a parent
context, child contexts are now able to configure their own server
properties.

Prior to this commit, Spring Boot would auto-configure Spring MVC and
would keep the default `UrlPathHelper` configuration.
Since Spring Boot is in charge of configuring the `DispatcherServlet`
and its mapping, it is in a position to optimally configure the
`UrlPathHelper` depending on the chosen mapping.
This commit sets the `alwaysUseFullPath` property of `UrlPathHelper` if
the Servlet mapping is `"/"`. This is more efficient since this
configuration requires less processing of the request path.

Prior to this commit, the property was a Boolean with a null default.
If it was explicitly set by the user, a context customizer would use
that value to set it on the context. However, if it was not set, the default

`false` in `TomcatServletWebServerFactory`. This commit defaults the property
itself to `false` so that the default is more obvious to the user.

Prior to this commit, there was a property server.error.include-details

server.error.include-binding-errors. When the message attribute is
excluded from a servlet response, the value is changed from a
hard-coded text value to an empty value.

Starting the CouchbaseContainer fails intermittently when creation
of the primary index for the bucket fails with a read timeout. The
test doesn't require a primary index for the bucket so this commit
disables it creation in the hope that it will help to stabilise the
test.
Previously, DefaultResourceLoader instances were created using the
default constructor. This causes the resource loader to capture the
TCCL that was in place at that time. This can lead to a class loader
leak if the resource loader is referenced directly or indirectly from
a static field of a class loaded by a different class loader.
This commit updates the creation of DefaultResourceLoader instances
in main code so that the resource load will use the class loader of
the creating class. In almost all cases this will be the same class
loader as was the thread context class loader that was being captured
so the change in behavior is minimal. Crucially, it will still address
the situation where the TCCL was different.
Note the DevTools' ApplicationContextResourceLoader has been updated
to explicitly use the TCCL. This ensures that it uses the restart
class loader which is required for DevTools to function correctly.

At present, RestClientBuilderCustomizer allows general customization of RestClientBuilder.
This is troublesome for users that want to customize `HttpAsyncClientBuilder` and

connection-timeout and read-timeout properties from `"spring.elasticsearch.rest"` namespace.
This commit enhances the `RestClientBuilderCustomizer` with support for customizing
`HttpAsyncClientBuilder` and `RequestConfig.Builder` by providing additional `customize`
methods that accept the aforementioned builders. Both new methods are optional as they have
