Rework the ConfigurationPropertySources and related adapter classes to
help with performance. The ConfigurationPropertySources class now only
monitors for updates when `.attach` is used. The `.get` methods now
return the adapted version, but no longer checks to see if sources have
been added or removed on each call.
This commit also fixes a few caching issues and makes both the
`PropertyMapper` implementations true static singletons.

Relax `SpringBootTestContextBootstrapper` rules so that a test can
specify an `ApplicationContextInitializer` and still have
`@SpringBootConfiguration` detected.
Prior to this commit detection would not occur because it's possible
that an initializer _could_ register configuration. This scenario is
actually quite unlikely to occur, certainly less likely than wanting to
use an initializer in combination with auto-detection.
Fixes gh-8483
Update SpringBootTestContextBootstrapper to detect `@ContextHierarchy`
annotations so that only the last child creates a
`WebApplicationContext`.
Prior to this commit a context hierarchy would start two embedded web
servers which is inconsistent with the `SpringApplicationBuilder`
behavior.
Fixes gh-8311
Restructure `org.springframework.boot.autoconfigure.web` to better align
with the new package structure in `spring-boot`.
Auto-configuration is now split into client, servlet and reactive
sub-packages. In addition a new `http` package now handles common
HTTP concerns.
Fixes gh-8616
Unify common for from the abstract `ServletWebServerFactory` and
`ReactiveWebServerFactory` classes. Common code is now located in
`AbstractConfigurableWebServerFactory`.
Fixes gh-8631
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 add mock support for WebFlux with an infrastructure similar
to what `WebMvcTest` provides. `@WebFluxTest` can be used to test
controllers with a narrowed classpath that is relevant to WebFlux. Also,
`@SpringBootTest` now starts WebFlux in "mock" mode by default and
`@AutoConfigureWebTestClient` can be used to inject a `WebTestClient`
connected to the `ApplicationContext`.
To make that happen, a `ReactiveWebApplicationContext` interface has been
introduced to mirror what `WebApplicationContext` currently does. Things
are still a bit volatile at this point and that infra may move to Spring
Framework at some point.
Closes gh-8401
This commit exposes a `WebTestClient` automatically in a reactive
integration test that uses an embedded web server. This is similar to
what we do with `TestRestTemplate` for servlet based integration tests.
Closes gh-8399
This commit makes sure that `@SpringBootTest` with a reactive setup
starts a web application if necessary.
If both a servlet and a reactive environment are available, a servlet
environment is bootstraped. This commit also adds a way to force a
reactive environment by specifying the `spring.main.web-application-type`
property of the test (e.g. `@TestPropertySource`).
Closes gh-8383
