Add an `DispatcherServletPath` interface which provides a much more
consistent way to discover the path of the main dispatcher servet.
Prior to this commit, auto-configurations would often make use of the
`ServerProperties` class to discover the dispatcher servlet path. This
mechanism isn't very explicit and also makes it hard for us to relocate
that property in Spring Boot 2.1.
This commit also reverts most of fddc9e9c7e since it is now clear that
the supporting multiple dispatcher servlet paths will be much more
involved that we originally anticipated.
Closes gh-13834
Previously, when a DispatcherServlet was registered via a
ServletRegistrationBean, the mappings endpoint did not expose any
information about it as it wasn't detected.
This commit fixes the detection of available DispatcherServlets in the
context so that the mappings endpoint include them all.

This commit improves the for Actuator Metrics in WebClient.
Unlike the server couterpart of WebFlux, using a `retry` operator on a
`WebClient` pipeline does resubscribes to the whole chain.
The previous implementation recorded start time at the time of pipeline
build phase, but outside of it. This doesn't work since retrying the
same pipeline doesn't update the recorded start time and the duration of
sequential calls are cumulative.
This is now fixed using the Reactor `Context`, since we're now recording
the start time at subscription time and record metrics on `onNext` and
`onError` signals.
Closes gh-12228
Previously, a NullPointerException would occur when WebFluxTags
attempted to create a method Tag for a request with a non-standard
method.
This commit updates WebFluxTags to use getMethodValue(), which will
never return null, rather than getMethod(), which may return null,
when determining the tag's value for the given request.
Closes gh-13596
As of Spring Framework 5.1, we're depending on the Reactor Californium
release train.
Reactor Netty is now at version 0.8 and changed its artifact
coordinates, package names and broke several APIs. Spring Framework is
now up-to-date with those changes and this commit does the same for
Spring Boot.
Note that in that process, the `NettyServerCustomizer` has been changed
since the former `HttpServerOptions.Builder` API is now gone from
Reactor Netty, and we're now relying on immutable server instances
instead of a stateful builder pattern.
See gh-13321
Previously, WebMvcTags would fall back to using the request’s path
info if Spring MVC’s best matching path pattern attribute was not
available. For non-Spring MVC web frameworks that support path
variables, such as Jersey, this led to an explosion of URI tags that
could exhaust the heap.
Closes gh-12447
This commit fixes endpoint extension discovery when the related endpoint
is sub-classed. Previously, a strict by type check was applied against
the `endpoint` attribute of `EndpointExtension`.
Rather than using a `Class` check, this commit extracts the id of an
endpoint and uses it to match its extension, if any.
Closes gh-13082
This commit improves the `health` endpoint to run health check for a
particular component or, if that component is itself a composite, an
instance of that component.
Concretely, it is now possible to issue a `GET` on
`/actuator/health/{component}` and
`/actuator/health/{component}/instance` to retrieve the health of a
component or an instance of a composite component, respectively.
If details cannot be showed for the current user, any request leads to a
404 and does not invoke the health check at all.
Closes gh-8865
This commit updates the initial proposal to add support for reactive
use cases as well. A reactive application can use
ReactiveHealthIndicatorRegistry as an alternative to
HealthIndicatorRegistry.
Closes gh-4965
This commit introduces HealthIndicatorRegistry which handles
registration of HealthIndicator instances. Registering new
HealthIndicator instances is now possible in runtime.
See gh-4965
This commit improves the initial proposal by providing a by name read
operation that returns the detail of a particular cache. It also adds
more tests and complete API documentation for the feature.
Closes gh-12216
This commits adds an actuator endpoint which lists the caches per
context and cacheManager and provides a delete operation to clear the
caches. As the statistics are exposed via the metrics endpoint they are
not included
See gh-12216
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.
