As of spring-projects/spring-framework#28341, `WebClient` is
instrumented directly for `Observation`.
This commit removes the custom `ExchangeFilterFunction` that previously
instrumented the client for metrics.
As a result, the relevant tag providers are now deprecated and adapted
as `ObservationConvention` for the time being.
Closes gh-32518
Prior to this commit, Spring Boot would auto-configure a customizer that
instruments `RestTemplate` through a `RestTemplateBuilder`. This would
install a request interceptor that instrumented client exchanges for
producing metrics.
As of spring-projects/spring-framework#28341, the instrumentation is
done at the `RestTemplate` level directly using the `Observation` API.
The `Tag` (now `KeyValue`) extraction, observation name and
instrumentation behavior now lives in the Spring Framework project.
This commit updates the auto-configuration to switch from Boot-specific
Metrics instrumentation to a generic Observation instrumentation.
As a migration path, some configuration properties are deprecated in
favor of the new `management.observations.*` namespace.
Closes gh-32484
Any classes that rely on Spring Data being on the classpath
have been moved under a data package.
Certain configuration properties have also been updated to
accurately reflect whether Spring Data is required for the
auto-configuration to work.
Closes gh-11574
This commit adds the Spring for GraphQL auto-configuration back
into Spring Boot 3.0, now that a 1.1.0 release is scheduled with the
required baseline. This release also needs GraphQL Java 19.0 as a
baseline.
Closes gh-31809
Update `NamedContributorsMapAdapter` so that the adapter function is
called only once per entry. Prior to this commit, the adapter was called
dynamically which made `CompositeHealthContributor` behave differently
from a regular `HealthContributor`.
