Restructure actuator packages to improve structure. The following
changes have been made:
- Separate actuator and actuator auto-configuration into different
modules.
- Move endpoint code into `spring-boot-actuator`.
- Move `Endpoint` implementations from a single package into
technology specific packages.
- Move `HealthIndicator` implementations from a single package into
technology specific packages.
- As much as possible attempt to mirror the `spring-boot` package
structure and class naming in `spring-boot-actuator` and
`spring-boot-actuator-autoconfigure`.
- Move `DataSourceBuilder` and DataSource meta-data support from
`spring-boot-actuator` to `spring-boot`.
Fixes gh-10261
This commit combines security autoconfigurations for
management endpoints and the rest of the application. By default,
if Spring Security is on the classpath, it turns on @EnableWebSecurity.
In the presence of another WebSecurityConfigurerAdapter this backs off
completely. A default AuthenticationManager is also provided with a user
and generated password. This can be turned off by specifying a bean of
type AuthenticationManager, AuthenticationProvider or UserDetailsService.
Closes gh-7958
This commit moves CORS properties out of the endpoints namespace as they
do not refer to a "cors" endpoint but rather to the CORS configuration
of all endpoints.
Closes gh-10053
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.
