Previously, the endpoint used the same change log history service for
for each SpringLiquibase bean that it processed. This resulted in
pollution of the reported changes as the history of each bean was not
isolated.
This commit updates the endpoint to use a new history service for each
SpringLiquibase bean that is processed.

Prior to this commit, ApiVersion was treated as a mandatory parameter in
CachingOperationInvokerAdvisor and thus prevented the
CachingOperationInvoker to kick in. By skipping ApiVersion in the same
way we're skipping SecurityContext we can avoid this.
In order to not return the same cached response, this commit also
changes the cache handling in CachingOperationInvoker to account for
different ApiVersions being passed.
See gh-18961
This commit makes sure that the health endpoint returns a default health
status when no contributors are available. Previously, it was returning
`null` which leads to a 404 when exposed via HTTP.
Closes gh-18676
Previously, @EndpointFilter would only have an effect when used as
an annotation or meta-annotation on the endpoint class itself. It
would have no effect when used on a super-class of the endpoint
bean's class.
This commit updates EndpointDiscoverer so that an @EndpointFilter
annotation or meta-annotation on a super-class will be found and
applied to the discovery process. This is achieved by using find…
rather than get… when retrieving the attributes for the EndpointFilter
annotation.
Fixes gh-17866
Update `NamedContributorsMapAdapter` to check for `null` keys or values
during construction. Also update `HealthEndpointSupport` to allow
null component entries.
See gh-18687
Update `HealthEndpointSupport` so that aggregate elements that don't
ultimately provide a contribution are filtered out. Prior to this
commit an NPE was returned when calculating the aggregate status.
Fixes gh-18687
Extract reactor specific code to an inner class to protect
against ClassNotFound exceptions if reactor is not in use.
Also add support for `Flux`.
See gh-18339
Update `CachingOperationInvoker` so that TTL caching is applied directly
to reactive types. Prior to this commit, a `Mono` would be cached, but
the values that it emitted would not.
See gh-18339
Add a `show-components` property under `management.endpoint.health` and
`management.endpoint.health.group.<name>` that can be used to change
when components are displayed.
Prior to this commit it was only possible to set `show-details` which
offered an "all or nothing" approach to the resulting JSON. The new
switch allows component information to be displayed whilst still hiding
potentially sensitive details returned from the actual `HealthIndicator`.
Closes gh-15076
Update the health endpoint so the nested components are now exposed
under `components` rather than `details` when v3 of the actuator
REST API is being used.
This distinction helps to clarify the difference between composite
health (health composed of other health components) and health
details (technology specific information gathered by the indicator).
Since this is a breaking change for the REST API, it is only returned
for v3 payloads. Requests made accepting only a v2 response will have
JSON provided in the original form.
Closes gh-17929
Add `ApiVersion` enum that can be injected into actuator endpoints if
they need to support more than one API revision.
Spring MVC, WebFlux and Jersey integrations now detect the API version
based on the HTTP accept header. If the request explicitly accepts a
`application/vnd.spring-boot.actuator.v` media type then the version
is set from the header. If no explicit Spring Boot media type is
accepted then the latest `ApiVersion` is assumed.
A new v3 API revision has also been introduced to allow upcoming health
endpoint format changes. By default all endpoints now consume and
can produce v3, v2 and `application/json` media types.
See gh-17929
Allow legacy actuator endpoint IDs that contain dots to be transparently
migrated to the new format. This update will allow Spring Cloud users
to proactively migrate from endpoints such as `hystrix.stream` to
`hystrixstream`.
Closes gh-18148
Refactor the `org.springframework.boot.actuate.context` package
with the following changes:
- Deprecate several classes which would ideally be internal
- Replace `ConfigurationBeanFactoryMetadata` with a new
`ConfigurationPropertiesBean` class to better reflect that we no
longer maintain meta-data directly.
- Use constructor injection and final fields whenever possible
- Rename `ConfiguraionPropertiesBeanDefinition` to
`ConfigurationPropertiesValueObjectBeanDefinition` to align
with the binder changes made in commit 0b3015e4ff
- Add additional tests
Closes gh-16903
Prior to this commit, Spring Boot would use `Schedulers.elastic()` when
required to process blocking tasks in a reactive environment.
reactor/reactor-core#1804 introduced a new scheduler,
`Schedulers.boundedElastic()` that behaves quite similarly but:
* will limit the number of workers thread
* will queue tasks if no worker thread is available and reject them is
the queue is exceeds a limit
This allows Spring Boot to schedule blocking tasks as before and allows
greater flexibility.
Fixes gh-18269
