Previously, if a user's configuration class provided a custom
Validator bean, that configuration class would be initialized very
early so that the Validator could be used to create the
auto-configured MethodValidationPostProcessor. This early
initialization could problems as it may prevent any of the
configuration class's dependencies from being post-processed.
This commit updates the injection of the Validator bean to be lazy,
thereby preventing the creation of the auto-configured
MethodValidationPostProcessor from triggering early initialization.

This commit removes the only use of the `javax.annotation.Resource`
annotation from the codebase. This ensures that injection point are

In an MVC web application, DelegatingWebMvcConfiguration provides the
ConversionService while also consuming WebMvcConfigurerAdapters that,
among other things, can configure HTTP message converters. Boot's
WebMvcConfigurerAdapter, WebMvcAutoConfigurationAdapter, consumes
the HttpMessageConverters bean and uses it to configure Spring MVC's
HTTP message converters. This can create a bean dependency cycle if
an HTTP message converter bean depends, directly or indirectly on
the ConversionService. An example of the cycle is:
┌─────┐
| jsonComponentConversionServiceCycle.ThingDeserializer defined in …
↑ ↓
| org.springframework.boot.autoconfigure.web.WebMvcAutoConfiguration$EnableWebMvcConfiguration
↑ ↓
| org.springframework.boot.autoconfigure.web.WebMvcAutoConfiguration$WebMvcAutoConfigurationAdapter
↑ ↓
| org.springframework.boot.autoconfigure.web.HttpMessageConvertersAutoConfiguration
↑ ↓
| mappingJackson2HttpMessageConverter defined in class path resource [org/springframework/boot/autoconfigure/web/JacksonHttpMessageConvertersConfiguration$MappingJackson2HttpMessageConverterConfiguration.class]
↑ ↓
| jacksonObjectMapper defined in class path resource [org/springframework/boot/autoconfigure/jackson/JacksonAutoConfiguration$JacksonObjectMapperConfiguration.class]
└─────┘
This commit breaks the cycle by making WebMvcAutoConfigurationAdapter
consume HttpMessageConverters lazily. This allows the adapter to be
created without triggered instantiation of every HTTP message
converter bean and all their dependencies. This allows it to be
injected into DelegatingWebMvcConfiguration without triggering an
attempt to retrieve the ConversionService.

Previously, when the liquibase.url, .username, and .password
properties were used to configure a DataSource specifically for
Liquibase that DataSource would never be explicitly closed. As it is
created by DataSourceBuilder with no explicitly configured type it
will use whichever connection pool is available and, therefore, will
create and keep open the pool's minimum number of connections. This
is an unnecessary use of resources both in the application and in the
database.
This commit updates LiquibaseAutoConfiguration so that if it uses
DataSourceBuilder to create a DataSource then it will also close that
DataSource once the database has been migrated.

This commit ensures that a primary JSR 303 and Spring Validator will be
exposed if the auto-configuration kicks in. As `LocalValidatorFactoryBean`
exposes 3 contracts (JSR-303 `Validator` and `ValidatorFactory` as well as
the `Spring` validator one), this makes sure that those types can be
injected by type.
`LocalValidatorFactoryBean` exposes 3 contracts and we're only checking
for the absence of a `javax.validation.Validator` to auto-configure a
`LocalValidatorFactoryBean`. If no standard JSR validator exists but a
Spring's `Validator` exists and is primary, we shouldn't flag the
auto-configured one as `@Primary`. Previous iterations on this feature
have made sure that we'll auto-configure at most one
`javax.validation.Validator` so not flagging it `@Primary` is no problem.
This commit also restores and adds tests that validates
`ValidationAutoConfiguration` will configure a JSR validator even if a
Spring Validator is present.
This effectively fixes gh-8495 in a different way.

Relax `SpringBootTestContextBootstrapper` rules so that a test can
specify an `ApplicationContextInitializer` and still have
`@SpringBootConfiguration` detected.
Prior to this commit detection would not occur because it's possible

actually quite unlikely to occur, certainly less likely than wanting to
use an initializer in combination with auto-detection.
Fixes gh-8483
Update `ValidationAutoConfiguration` and `WebMvcAutoConfiguration` to
ensure as much as possible that only a single Validator bean of each
type is registered.
Validation auto-configuration now does the following:
- If no validator is found: Registers a `LocalValidatorFactoryBean`
(providing both Spring and JSR validation)
- If the user defines a Spring & JSR validator: Backs off
- If the user defines only a JSR validator: Adapts it to a Spring
validator (without exposing another JSR implementation)
WebMvcAutoConfiguration auto-configuration has been updated to make
MVC validation follow common Spring Boot patterns:
- If not validator beans are found (due to the user excluding
ValidationAutoConfiguration) a new `mvcValidator` bean will be
registered.
- If a single validator bean is found it will be used for MVC
validation.
- If multiple validator beans are defined it will either use the one
named `mvcValidator` or it will register a new `mvcValidator` bean
Any automatically registered `mvcValidator` bean will not implement
the JSR validator interface.
Finally, it is no longer possible to provide an MVC validator via a
`WebMvcConfigurer`.

Update `ResourceServerTokenServicesConfiguration` to fail fast if the

Previously, WelcomePageHandlerMapping would forward to index.html.
This assumed that the static path pattern was always /**. If it had
been customised to, for example, /foo/**, then the forward would still
be to index.html and a 404 would result as the page is actually
available at /foo/index.html.
At first glance, it would appear that the forward should be made to
foo/index.html. However, as it's a forward rather than a redirect,
any relative URLs in the index.html page would then be resolved using
/ whereas they should be resolved using /foo/. This could be addressed
by using a redirect rather than a forward, but we don't want to do
that as it's more invasive and would require a roundtrip back to the
client. Instead, this commit simply stops performing the forward when
the static path pattern is not /**.

Previously to this commit, transaction management was only enabled when
a `DataSource` is configured. The processing of `@Transactional`

This commit makes sure that if a `javax.cache.CacheManager` is required,
an auto-configured `HazelcastInstance` is fully resolved first. This
prevents the case where the JCache bootstrap actually starts an instance
early, followed by a second (potentially unwanted) instance created by the
regular auto-configuration.
Since the JCache implementation works with an `HazelcastInstance` behind
the scenes, if there is one `HazelcastInstance` configured and it has a
name, then we configure the `CacheProvider` to use that. Future Hazelcast
version will allow to pass the instance directly (i.e. not requiring an
actual name).
Closes gh-8484
This commit flags the two `BeanPostProcessors` registered by the

This commit makes sure that if `local.mongo.port` is set, a `MongoClient`
on the embedded MongoDB instance is created. When an embedded instance

switches to the embedded server, even if a production uri has been
specified.

Rework Spring MVC JSR-303 validation support a little more to move
most of the creation logic to the wrapper class. Also rename
`SpringValidatorAdapterWrapper` -> `WebMvcValidator`.
See gh-8223
This commit improves the initial solution by actually overriding the
`mvcValidator` `@Bean`. This gives us more control as whether a custom
validator has been specified or not. We now wrap it regardless of it
being custom or provided by auto-configuration.
Closes gh-8223
`MethodValidationPostProcessor` requires a `Validator` so we need to flag
it as an infrastructure bean to prevent an additional log that indicates
it won't be post-processed.
We obviously don't want to post-process the `Validator` here so adding the
additional meta-data is a good idea anyway.
Closes gh-8422
This commit makes sure that the Spring `Validator` used by the MVC
layer doesn't expose a JSR-303 contract, if any.
The default implementation of the `mvcValidator` is
`LocalValidatorFactoryBean`. While this object is exposed as a Spring
`Validator` only, its runtime capabilities expose that contract as well
as the standard `Validator` and `ValidatorFactory` ones.
Concretely, if an auto-configuration is checking if a
`javax.validation.Validator` bean is missing, the condition will match
since we only know about "advertized types": beans haven't been created
yet so we can't inspect their runtime capabilities. Since the condition
match, we will auto-configure a bean. At runtime though, we're no longer
ale to inject a `javax.validation.Validator` by type since two candidates
are available.
This commit introduces `SpringValidatorAdapterWrapper`, a wrapper class
on any `SpringValidatorAdapter` (`LocalValidatorFactoryBean` being one of
the available implementations) that only exposes the Spring contract.
Also, if a `javax.validation.Validator` bean is available, we will use it
for the MVC layer, rather than creating a new one.

The verifier's type checker is required to check that a type returned
from a method (an areturn instruction) is assignable to the method's
declared return type. When the return type is an interface, the JLS
states that it should be treated as java.lang.Object. This means that
no analysis of the type being returned is required and verification
passes. When the return type is a class, the type being returned must
be analyzed to ensure that it is compatible. This analysis causes the
return type to be loaded during verification.
Prior to this commit, BasicBatchConfigurer's
createAppropriateTransactionManager method had a return type of
AbstractPlatformTransactionManager and a branch that could return
a JpaTransactionManager. This caused the verifier to attempt to load
JpaTransactionManager so that it could check that it was assignable
to AbstractPlatformTransactionManager. This would fail when
spring-orm is not on the classpath as JpaTransactionManager could not
be loaded.
This commit updates BasicBatchConfigurer to change the return type
of createAppropriateTransactionManager so that it returns a
PlatformTransactionManager which is an interface. As described above,
this relaxes the verification of any areturn instructions in the
method and, in this particular case stops the verifier from trying to
load JpaTransactionManager.

unrelated annotations.
A new `DeterminableImports` interface has been added that can be

this interface.

Previously, Hibernate Validator would fail to initialize if it was
on the classpath but an EL implementation was not.
OnValidatorAvailableCondition protected against this scenario by
initializing the validator.
The Hibernate Validator shortcoming was addressed in eb222209

ValidationProvider META-INF/services resource is now sufficient to
auto-configure validation. This commit removes
OnValidatorAvailableCondition as it is no longer necessary.

In version 2.3.6 and earlier, an attempt to create a Bucket or a
ClusterInfo would fail fast with a ConnectException in the cause of
the Couchbase server was done. In 2.3.7 this remains true for a
Bucket but is no longer the case for ClusterInfo. The latter now
retries for 75 seconds by default and when it eventually fails a
ConnectException is no longer part of the cause chain.
This commit makes the auto-configured ClusterInfo depend on the
auto-configured Bucket. This means that the Bucket is always created
before the ClusterInfo, thereby ensuring that things fail gracefully
with useful diagnostics when the server is unavailable.
