This commit adds micrometer's default values for each monitoring
system with tests that validate those defaults are consistent. This
makes sure that those defaults are part of the metadata and any tooling
support that uses it.
Closes gh-12089
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
