This commit migrates the Actuator onto the new endpoint infrastruture.
In addition to the existing support for accessing the endpoints via
JMX and HTTP using Spring MVC, support for access via HTTP using
Jersey and WebFlux has been added. This includes using a separate
management port where we now spin up an additional, appropriately
configured servlet or reactive web server to expose the management
context on a different HTTP port to the main application.
Closes gh-2921
Closes gh-5389
Closes gh-9796
This commit replaces the Acuator's support for hypermedia with a
single endpoint that returns HAL-formatted links to all of the
available endpoints. This is done without requiring Spring HATEOAS
to be on the classpath in a similar manner to the existing
CloudFoundry discovery endpoint.
Closes gh-9901
Rework `org.springframework.boot.context.embedded` to relocate classes
to `org.springframework.boot.web`. Packages are now organized around
the following areas:
Packages for shared concerns, for example the `WebServer` interface
to start/stop a server and the common configuration elements:
- org.springframework.boot.web.context
- org.springframework.boot.web.server
Servlet specific packages:
- org.springframework.boot.web.servlet.server
- org.springframework.boot.web.servlet.context
- org.springframework.boot.web.servlet.filter
Reactive specific packages:
- org.springframework.boot.web.reactive.context
- org.springframework.boot.web.reactive.server
Embedded server implementations (both reactive and servlet):
- org.springframework.boot.web.embedded
In addition:
- Rename `EmbeddedServletContainerFactory` to `ServletWebServerFactory`
to align with the `ReactiveWebServerFactory`.
- Rename `EmbeddedWebApplicationContext` to
`ServletWebServerApplicationContext` and
- Rename `EmbeddedReactiveWebApplicationContext` to
`ReactiveWebServerApplicationContext`.
- Add checkstyle rules to restrict imports.
- Fixup all affected code to use the correct imports and local names.
Fixes gh-8532
This commit refactors the `ServerProperties` property keys and
introduces a separate "server.servlet" namespace to isolate
servlet-specific properties from the rest.
