When running on Java 11 (where `@PostConstruct` is no longer part of
the JRE) and without a dependency on jakarta-annotation-api,
`@PostContruct` annotions are silently dropped. This leads to obscure and
hard-to-track down changes in the behaviour of our auto-configuration
as the `@PostConstruct`-annotated methods are not invoked.
To allow users to run on Java 11 without having jakarta-annotation-api
on the classpath, this commit removes use of `@PostConstruct` from main
code. A Checkstyle rule has also been added to prevent its usage in
main code from being reintroduced.

Previously, the test would make an HTTP request and, as soon as the
response was received, it would check the presence and value of the
http.server.requests meter. This create a race condition between the
meter being registered once the response had been flushed and the
meter's presence being checked. If the check won the race, the test
would fail.
This commit updates the test to wait for up to 5 seconds for the
meter to be present and have a count of 1, matching the single request
that has been made.
Fixes gh-23919
Add a dedicate condition annotation to detect when Spring Security is
available but has not been configured by the user. The new annotation
helps simplify quite a few of our auto-configuration classes.

Replace `WebSecurityConfigurer` and `WebSecurityConfigurerAdapter`
configurations with `WebSecurityCustomizer` or `SecurityFilterChain`

Previously, the base path of a servlet-based management server could be
configured using management.server.servlet.context-path but there was no
equivalent property for WebFlux.
This commit introduces a new property, management.server.base-path,
that can be used with both servlet and reactive management servers. The
existing servlet-specific property has been deprecated in favour of the
new general property. When using the servlet stack, if both the general
property and the servlet-specific property are set, the new general
property takes precedence. When using the reactive stack, only the new
general property is considered.
Closes gh-22906
This commit makes sure to defer registration of hibernate statistics
outside of the singleton lock as it can lead to deadlocks when the
EntityManagerFactory is initialized in deferred mode.
Closes gh-23740
This commit adds support for Redis cache metrics. Users can opt-in for
statistics using the "spring.cache.redis.enable-statistics" property.
Closes gh-22701
Constructor calls like new AtomicInteger(0) cause a volatile write that
can be saved in cases where the constructor parameter is the default
value.

Previously, all MeterFilter beans were applied to all MeterRegistry
beans. As a result, when a composite registry was auto-configured, both
the composite and all of its delegates would have the same MeterFilters
applied. This made it impossible for one of the delegate registries to
have a locally-configured filter that would allow a meter that would be
denied by one of the MeterFilter beans applied to the composite.
This commit update MeterRegistryConfigurer to skips the auto-configured
composite meter registry when applying MeterFilter beans to
MeterRegistry beans. As a result, the composite's filters will no
longer deny a meter before it reaches a delegate that would have
accepted it due to one of its locally-configured filters.

With the introduction of health indicators that only require the
CqlSession, this commit deprecates the health indicators that require
Spring Data since the latter build on top of the former.
Closes gh-23226
Prior to this commit, Spring Boot would auto-configure both
Elasticsearch variants: `RestClient` ("Low Level" client) and
`RestHighLevelClient` ("High Level" client).
Since one can be derived from the other, this would create complex and
unclear situations depending on what developers provided with their
configuration.
`RestHighLevelClient` is mostly for actual use of the Elasticsearch API,
with support for specific methods and (de)serialization. On the other
hand, `RestClient` is merely wrapping the Apache HTTP client for
load-balancing support and low level HTTP features.
This commit completely removes the support for `RestClient` in Spring
Boot and now requires the presence of the
`org.elasticsearch.client:elasticsearch-rest-high-level-client`
dependency for REST client support with Elasticsearch.
Closes gh-22358
This commit builds on top of gh-22603 and exposes data collected by the
`BufferingApplicationStartup` on a dedicated `"/startup"` Actuator
endpoint.
Closes gh-23213
Rename `CompositeMeterRegistryAutoConfiguration` to
`MeterRegistryAutoConfiguration` since it can also create non-composite
registries.
Closes gh-22988
Update metrics auto-configurations so that they are auto-configured
after `CompositeMeterRegistryAutoConfiguration` in order to ensure
the `MeterRegistry` bean has been defined.
Prior to this commit, metrics auto-configurations that depended on a
`MeterRegistry` has `@AutoConfigureAfter(MetricsAutoConfiguration.class)`
which is not sufficient since `MetricsAutoConfiguration` does not export
a `MeterRegistry`.
See gh-21134
Previously, the endpoints' responses could occasionally exceed
WebClient's in-memory buffer limt, for example if the threads endpoint
was reporting a large number of threads or the threads had large
stacks.
This commit disables WebClient's in-memory buffer size limit so that
the tests passing is not dependent on the size of the endpoints'
responses.
Closes gh-22743
Prior to this commit, the livenessState and readinessState health
indicators would not be configured automatically and would be missing
from the "liveness" and "readiness" health groups, leading to 404s when
hitting the `/actuator/health/liveness` or `/actuator/health/readiness`.
This commit ensures that the health indicators beans have the proper
name and revisits the auto-configuration conditions to reflect that as
well.
Fixes gh-22562
This commit replaces the Neo4j-OGM based health checks with one based on
the Neo4j Java driver. A Reactive variant is also added in this commit.
See gh-22302
This commit harmonizes dependency declarations for Jackson in the
actuator. Both Jackson and JSR 310 are back to optional in the core
actuator module and mandatory when using the auto-configuration.
Closes gh-22624
The generated snippets were not declared as an output to the
`spring-boot-actuator-autoconfigure` test goal so when the test was
pulled from the cache, it did not contain the `generated-snippets`
directory. This directory is required as an input to the Asciidoctor
plugin.
See gh-22555
This commit introduces a new property to globally disable metrics
export. In integration tests, this property is automatically set to
disable everything but in-memory metrics.
This commit also introduces a `@AutoConfigureMetrics` annotation that
can be used for integration tests that require metrics export to operate
as they would in an application.
See gh-21658
Prior to this commit, the application availability infrastructure
would mix the `AvailabilityState`, the `HealthIndicator` and the
`HealthGroup` concepts and would not align with the rest.
This commit auto-configures the livenessState and readinessState
health indicators with the relevant configuration properties.
Unlike other indicators, they are not enabled by default but might
be in future versions.
This also moves the `management.health.probes.enabled` property
to `management.endpoint.health.probes.enabled` since "probes" here
is not a health indicator but rather a configuration flag for the
health endpoint.
Finally, the probes auto-configuration is refined to automatically
add liveness and readiness indicators for the probes group if
they're not already present.
Closes gh-22107
Prior to this commit, configuring a reactive Elasticsearch client would
auto-configure an Actuator Health check using a synchronous client, with
the default configuration properties (so tarting localhost:9200).
This would lead to false reports of unhealthy Elasticsearch clusters
when using reactive clients.
This commit reproduces the logic for MongoDB repositories: if a reactive
variant is available, it is selected for the health check
infrastructure.
