Rename `/actuator/httptrace` to `/actuator/httpexchanges` to better
describe its purpose and to remove confusion with distribute tracing.
This change also takes the opportunity to improve the code by making
the `HttpExchange` class (previously `HttpTrace`) fully immutable.

Without this change we're missing the BaggageTextMapPropagator for
OTel. This means that we're not propagating remote-fields
(only baggage via the 'baggage' field).
With this change we're adding the missing propagator as
THE LAST entry in the composite TextMapPropagator. It has to be
last cause with the latest Snapshots of Micrometer Tracing it
will append the remote field baggage to existing baggage in the
context extracted via the W3CBaggagePropagator.

Prior to this commit, Spring Boot would offer a specific Metrics
instrumentation for WebFlux applications through a `WebFilter` and
custom Tag providers.
As of Spring Framework 6.0, the Observation instrumentation is done
directly in WebFlux, also with a `WebFilter`. While this allows both
metrics and traces, some features cannot be supported in the same way
with this new infrastructure.
The former `WebFilter` has been removed and the Tagging infrastructure
deprecated in favor of custom Observation conventions. This commit
provides an adapter layer so that developers can refactor their custom
tagging solution to the convention way, during the deprecation phase,
without losing any feature.
Closes gh-32539
This commit migrates the existing metrics support (added in #29140) to
the new `Observation` instrumentation contributed in
spring-projects/spring-graphql#501.
We cannot have a smoother migration path here as the instrumentation
does not use the same context information for metadata extraction.
Closes gh-32794
This commit moves the entire Metrics auto-configuration for Spring MVC
to the new `Observation` API and the instrumentation contributed in
Spring Framework.
Closes gh-32538
This commits adds a checkstyle rule to not use List.of(), Set.of()
and Map.of(), preferring Collections.emptyList(), emptySet(), and
emptyMap() respectively.
It replaces usages of these methods across the codebase.

This commit updates the bean factory methods for beans that can be
instantiated at build-time to be static. Doing so makes sure that
the enclosing configuration class does not have to be resolved in
order to create the instance.
Closes gh-32570
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
Previously, RestTemplateBuilder and WebClient.Builder beans were used
to create the HTTP client for sending out spans. Those same beans are
also instrumented for observability which results in a cycle.
This commit breaks the cycle by not using the application-web
builders to create the RestTemplate and WebClient's used by the Zipkin
senders. Instead, builders are created inline, with new callbacks
being introduced to allow the user to customize these Zipkin-specific
builders.
See gh-32528
Previously, a Webclient-based sender was only for reactive web
applications, falling back to a RestTemplate-based sender in all
other cases.
With this commit we now prefer to use WebClient if it is available,
irrespective of the web application type. The assumption is that
if the user has WebClient on the classpath, it's either a reactive
web application, or it's a servlet web application or non-web
application but WebClient is preferred.
See gh-32529
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
This commit updates Servlet based Spring Security auto-configuration
to use AuthorizationFilter, which is intended to supersede
FilterSecurityInterceptor.
See gh-31255
With this commit, loading `@AutoConfiguration`,
`@ImportAutoConfiguration`, and `@ManagementContextConfiguration`
classes is supported with `.imports` files only. Support for loading
these classes with `spring.factories` is removed.
