Introduce a strategy to `WebApplicationType` to allow modules to
implement deduction logic.
Prior to this commit, modules played no part in deducing the
`WebApplicationType`. This meant that a user with `spring-webflux`
for client purposes would deduce `REACTIVE` despite no
`spring-boot-webflux` module being present.
The following deduction logic order is now implemented:
1) If the `spring-boot-webmvc` module is being used and Spring MVC
classes are found then `SERVLET` is used.
2) If the `spring-boot-webflux` module is being used and Spring WebFlux
classes are found then `REACTIVE` is used.
3) If `spring-web` is found and servlet classes are available then
`SERVLET` is used.
4) If none of the above are satisfied, `NONE` is used.
This commit also updates `SpringBootTestContextBootstrapper` to use
the same deduction logic.
Fixes gh-48517
Mirror the package names used in actuator for classes to support
mappings and exchanges in `spring-boot-servlet`, `spring-boot-webmvc`
and `spring-boot-webflux`.
Closes gh-46217
This commit modularizes spring-boot-test-autoconfigure. It now
contains only the code that's central to test auto-configuration.
Feature-specific functionality has moved out into -test modules,
some existing and some newly created. For example, `@DataJpaTest` can
now be found in spring-boot-data-jpa-test.
Closes gh-47322
Refactor `PropertyMapper` so that it no longer calls adapter or
predicate methods by default when the source value is `null`. This
effectively makes all default calls the same as using
`alwaysWhenNotNull` in the previous generation of the code.
For the limited times when you do need to deal with `null` values, the
new `always()` method can be used.
For example,
map.from(source::method).to(destination::method);
Will not call `destination.method(...)` if `source.method()` returns
`null`.
Where as:
map.from(source::method).always().to(destination::method);
Will call `destination.method(null)` if `source.method()` returns
`null`.
This update provides clearer semantics for the API and allows for better
JSpecify nullability annotations. It has also simplified much of our
existing property mapper code.
Closes gh-47024

The enum itself is not specifically tied to auto-configuration so
spring-boot is a better place for it. The related condition,
`@ConditionalOnThreading`, remains in spring-boot-autoconfigure. This
aligns things with the similar `CloudPlatform` and
`@ConditionalOnCloudPlatform`.
