Previously, a number of Actuator endpoints ignored a context hierarchy
or assumed that it would always be linear. This commit reworks the
affected endpoints so that the no longer assume a linear hierarchy.
A side-effect of a non-linear hierarchy is that there may be multiple
different beans with the same name (in a linear hierarchy, a bean
with the same name as one in an ancestor context, replaces that bean).
The affected endpoints have also been updated so that, when bean names
are used as keys, those keys are grouped by application context. This
prevents a bean in one context from accidentially overwriting a bean
in another context.
Closes gh-11019
This commit moves management.server.context-path to
management.server.servlet.context-path to align with the configuration
key for the application's main context path.
Closes gh-11359
Previously, the Health web extension was defined in the management
context and, as a result, it wasn't found when a separate port was
required. The side effect is that anything that the health web extension
does was not active anymore in that case.
This commit makes sure that the extension is always defined as part of
the main context where operations are discovered and merged.
Closes gh-11285
Drop the status endpoint and merge functionality back into the health
endpoint. The `management.endpoint.health.show-details` property can
be used to change if full details, or just the status is displayed.
Fixes gh-11113
Update endpoint code to provide cleaner separation of concerns.
Specifically, the top level endpoint package is no longer aware of
the fact that JMX and HTTP are ultimately used to expose endpoints.
Caching concerns have also been abstracted behind a general purpose
`OperationMethodInvokerAdvisor` interface.
Configuration properties have been refined to further enforce
separation. The `management.endpoint.<name>` prefix provides
configuration for a single endpoint (including enable and cache
time-to-live). These properties are now technology agnostic (they
don't include `web` or `jmx` sub properties).
The `management.endpoints.<technology>` prefix provide exposure specific
configuration. For example, `management.endpoints.web.path-mapping`
allow endpoint URLs to be changed.
Endpoint enabled/disabled logic has been simplified so that endpoints
can't be disabled per exposure technology. Instead a filter based
approach is used to allow refinement of what endpoints are exposed over
a given technology.
Fixes gh-10176
- Modifying dependencies to starter-web with tomcat exclusion plus
alternative servlet container instead of manual dependency on
spring-webmvc as it is the preferrable way to use alternative servlet
container
- Previously RestTemplate with ssl was configured manually in tests - now
it rellies on autoconfiguration - changed this for multi-connector test
and added test to ensure that ssl autoconfiguration is working
- Most samples with alterntative servlet containers used some kind of
service reading property and returning default since it wasn't
configured - removed it, since it is not specific to using alternative
servlet containers.
