The ConnectionFactory can be used early in user configuration to
configure an `Exchange`. Such connection may not hold the proper
MetricCollector and can be cached, leading to missed metrics
information.
This commit moves the configuration of RabbitMQ metrics to a
BeanPostProcessor so that the proper MetricCollector is configured
before any connection is created.

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.

Auto-configuration of LDAP's `LdapTemplate` is currently a part of
`LdapDataAutoConfiguration` which is conditional of presence of
`LdapRepository` (i.e. Spring Data LDAP). This arrangement isn't ideal
since the `LdapTemplate` is a part of Spring LDAP project, and therefore
should not be tied to Spring Data LDAP.
This commit improves and simplifies LDAP auto-configuration by moving
`LdapTemplate` configuration to `LdapAutoConfiguration`. Consequently,
`LdapDataAutoConfiguration` is not needed anymore and is removed.

Previously, when the Jersey-based Actuator was configure with a
separate management port, the resulting child context would fail to
start due to their being no ResourceConfigCustomizer beans available.
This commit updates the configuration so that the customizer's are
injected using an ObjectProvider and an empty list is used in the
event of their being no customizer beans. This aligns the child
context configuration class with JerseyAutoConfiguration which
already used this approach.
Closes gh-12975
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.
Closes gh-12228
All Hibernate entityManagerFactories are automatically instrumented
and their statistics are included into Micrometer using its
HibernateMetrics binder.
Closes gh-12550
Update `MeterRegistryConfigurer` to also apply customizers to
composite meter registries. Prior to this commit composites were
skipped due to the incorrect assumption that did not contain
their own state.
Closes gh-12762
Previously, when performing lazy initialisation of the context,
ApplicationContextRequestMatcher assigned the context field before it
called initialized. The context being non-null is used as the signal
that it’s ok to call a subclass’s matches method. If one thread checks
for a non-null context in between the field being assigned and
initialized being called on another thread, matches will be called
before the subclass is ready.
This commit closes the window for the race condition by only assigning
the context field once the subclass’s initialized method has been
called.
There is a secondary problem in each of the subclasses. Due to the use
of double-checked locking in ApplicationContextRequestMatcher, it’s
possible for a subclass’s matches method to be called by a thread that
has not synchronised on the context lock that’s held when initialized
is called and the delegate field is assigned. This means that the
value assigned to the field may not be visible to that thread.
This commit declares the delegate field of each
ApplicationContextRequestMatcher subclass as volatile to ensure that,
following initialisation, its value is guaranteed to be visible to
all threads.
