This commit polishes Kotlin nullable support by reusing
MethodParameter#isOptional() instead of adding a new
MethodParameter#isNullable() method, adds
Kotlin tests and introduces Spring Web Reactive
support.
Issue: SPR-14165
Where `isOptional` is used, also check for `isNullable` i.e.
values are not considered required if they are Kotlin nullables:
- spring-messaging: named value method arguments
- spring-web: named value method arguments
- spring-webmvc: request parts
This means that Kotlin client code no longer has to explicity specify
"required=false" for Kotlin nullables -- this information is inferred
automatically by the framework.
Issue: SPR-14165
Since https://jira.sonarsource.com/browse/SONARGRADL-30, we can now
safely update to sonarqube plugin v2.2.1.
The protobuf gradle plugin is now deprecated - instead of configuring
the new plugin supported by Google, this commits drops that part of the
gradle build since that proto->java conversion is rarely needed and can
be manually run by any member of the team.
- ScriptedSubscriber has been renamed to Verifier
- The Publisher is passed to create() instead of verify()
- No more need to specify the generic type explicitly
- Version is now sync with reactor-core
Issue: SPR-14800
Reactor recently added the `ScriptedSubscriber` in its new
`reactor-addons` module. This `Subscriber` revissits the previous
`TestSubscriber` with many improvements, including:
* scripting each expectation
* builder API that guides you until the final verification step
* virtual time support
This commit refactor all existing tests to use this new
infrastructure and removed the `TestSubscriber` implementation.
Issue: SPR-14800
This commit removes the usage of Reactor adapters (about to
be moved from Reactor Core to a new Reactor Adapter module).
Instead, RxReactiveStreams is now used for adapting RxJava
1 and Flowable methods are used for RxJava 2.
Issue: SPR-14824
A straight-forward port of the resource handling support in
spring-webmvc to spring-web-reactive. Primarily adapting contracts and
implementations to use the reactive request and response and the
reactive ResourceHttpMessageWriter.
