Refactor `ConfigurationPropertiesBindingPostProcessor` to allow JSR-303
validation on `@ConfigurationProperties` defined at the `@Bean` method
level.
JSR-303 validation is now applied when a JSR-303 implementation is
available and `@Validated` is present on either the configuration
properties class itself or the `@Bean` method that creates it.
Standard Spring validation is also supported using a validator bean
named `configurationPropertiesValidator`, or by having the configuration
properties implement `Validator`.
The commit also consolidates tests into a single location.
Fixes gh-10803
The `server.display-name` configuration property is used to configure
the application display name for Servlet-based applications.
This commit moves that property to:
`server.servlet.application-display-name` and keeps the same defaults.
Closes gh-8624
Remove custom `SpringIntegrationMetrics` and instead provide
auto-configuration to the direct Micrometer support added in Spring
Integration 5.0.2.
Closes gh-11985
As discussed in gh-11872, `TestRestTemplate` constructor variants taking
a `RestTemplate` argument are confusing since the main goal of that
class is to mutate `RestTemplate`.
This commit removes all those constructor variants and replaces them
with `RestTemplateBuilder` arguments when possible.
Closes gh-11872
Refactor `*ExportConfiguration` classes to be regular auto-configuration
classes.
Also removed the `@ConditionalOnProperty` guards for `.enabled` properties
since auto-configuration can now be excluded in the usual way. Enabled
properties remain where applicable and are adapted for Micrometer to use
as it sees fit.
Fixes gh-11838
