This commit adds support for Actuator Metrics for WebClient.
This support mirrors the current behavior for `RestTemplate`, reusing
the same metric name `"http.client.requests"` and tags.
`WebClient` is instrumented by a `MetricsWebClientFilterFunction` which
is applied by a `WebClientCustomizer`. This instrumentation happens
automatically only if you create an instance of `WebClient` using an
auto-configured `WebClient.Builder` bean.
This infrastructure is reusing de facto the `MeterFilter` that has been
added for `RestTemplate` in order to limit the "uri" tag cardinality.
Closes gh-12228
All Hibernate entityManagerFactories are automatically instrumented
and their statistics are included into Micrometer using its
HibernateMetrics binder.
Closes gh-12550
This commits make sure that the Quartz auto-configuration no longer
associates an `Executor` bean if present in the context as Quartz offers
properties to tune it, which would mutate and lead to unexpected
results.
Closes gh-12823
Spring Boot now deploys both annotation-based and functional endpoints
under the same `HttpHandler`; this means the currently auto-configured
`MetricsWebFilter` is instrumenting all endpoints to produce metrics.
There is no need for a WebFlux functional specific support.
This commit removes mentions of `RouterFunctionMetrics` in the docs and
deprecates that class.
Closes gh-12833
Documentation still refers to the now deprecated `EnvironmentTestUtils`
class instead of `TestPropertyValues` for setting environment values in
tests.
This commit replaces it with `TestPropertyValues` and provides an
equivalent code example.
Closes gh-12711
This commit updates WebTestClientAutoConfiguration to only create a
WebTestClient when running a WebFlux-based application as mocking the
context only works with that mode at the moment.
Closes gh-12318
