CachePublicMetrics wasn't explicitly tested and was still using field
injection. This commit improves the situation in preparation of the fix
for gh-8984
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.
Closes gh-8979
Closes gh-8976
`BasicErrorControllerIntegrationTest` is handling the context in each test
and yet it starts a useless test via `@SpringBootTest`. This commit
removes the useless runner and associated annotations.
Replace the MVC validator post processor with an `@Import` so
that a "cannot enhance @Configuration bean definition"
warning does not occur.
Fixes gh-8951
