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 contract is not specific to servlet containers and should be
reused by all web server implementations (including reactive variants).
Fixes gh-8208
This commit removes `ServerProperties` and `ManagementServerProperties`
auto-configurations. Those properties objects are now created using
`@EnableConfigurationProperties` only.
Closes gh-8108
Update TestRestTemplate so that it no longer directly extends
RestTemplate. Prior to this commit it was possible that TestRestTemplate
could interfere with user defined RestTemplate beans.
TestRestTemplate offers the same methods as RestTemplate so should be
a drop-in replacement. If access is needed to the actual underlying
template the `getRestTemplate()` method should be used.
Fixes gh-5915
Move the @LocalServerPort to org.springframework.boot.context.embedded
since it's only really useful when working with embedded servlet
containers.
See gh-5822
Rework the new testing support so that @SpringApplicationTest can be
used for standard integration tests, web integration tests with a
mock Servlet environment and web integration tests with an embedded
servlet container. This means that it a replacement for 1.3's
@IntegrationTest and @WebIntegrationTest and allows all
SpringApplication testing to be configured using a common annotation.
The old @IntegrationTest and @WebIntegrationTest along with their
supporting classes have been reinstated to their previous form (while
remaining deprecated). This should ensure that they continue to work
in 1.4 exactly as they did in 1.3 giving users a smooth path to
@SpringApplicationTest.
See gh-5477
Add a `server.server-header` property which can be used to override the
`server` header usually sent back automatically by Tomcat/Jetty or
Undertow.
See https://www.owasp.org/index.php/Securing_tomcat for background.
Fixes gh-4461
Closes gh-4504
