Refine Mustache support to provide a cleaner separation between the
reactive and servlet implementations. The views have now moved to the
`spring-boot` project and the auto-configuration has been split into
two distinct `@Imports` to save needing full package declarations.
See gh-8941
This commit simplifies the Mustache support for Spring MVC and removes
the included (view-based) i18n support in favor of more idiomatic
constructs like Mustache lambdas.
Fixes gh-8941
This commit moves the existing Spring MVC Mustache support to its own
`servlet` package and adds a new one under `reactive` for the WebFlux
web applications.
New `MustacheView` and `MustacheViewResolver` types resolve and render
Mustache views for WebFlux applications.
Since this templating engine is now supported by two flavors of Spring
web apps, the `spring-boot-starter-mustache` does not depend anymore on
the `spring-boot-starter-web` one: it's up to the developer to add the
relevant starter `web` or `webflux` to their application.

Replace the MVC validator post processor with an `@Import` so
that a "cannot enhance @Configuration bean definition"
warning does not occur.

Update `PropertiesLauncher` so that classes can be loaded outside of
`BOOT-INF/classes`. You can use a subdirectory, or the root directory
of an external jar (but not the parent archive to avoid issues
with agents and awkward delegation models).
Fixes gh-8480

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
that an initializer _could_ register configuration. This scenario is
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`.
Fixes gh-8495
Allow `PathExtensionContentNegotiationStrategy` to be bypassed by
actuator endpoints. Prior to this commit calling `/loggers/com.aaa.cab`
would return a HTTP 406 response due to `.cab` being a known extension.
Fixes gh-8765
Update `ResourceServerTokenServicesConfiguration` to fail fast if the
`getKeyFromServer()` call fails. Since the key is part of the singleton
`JwtAccessTokenConverter` bean there is not real way to refresh without
restarting the application.
A hard failure seems preferable to an inconsistent state.
Closes gh-8924
Since SPR-15415 and SPR-15435, the HandlerStrategies and its companion
builder are now using the new CodecConfigurer infrastructure to
configure codecs in a cross-cutting way.
This commit looks for a custom instance of `HandlerStrategies.Builder`
provided by the user, or create a default one if none was found.
Fixes gh-8897
This commit makes sure to honour the `spring.aop.proxy-target-class`
property if set by the user. Previously, the
`PersistenceExceptionTranslationPostProcessor` was always configured to
use cglib, regardless of the value of that property.
Closes gh-8887
This commit separates the JPA-specific bits of the batch
auto-configuration so that it is possible to reuse most of the logic if
JPA isn't available at all.
Closes gh-8877
