Support @PathVariable in annotated message handling methods [SPR-10949]

[spring-projects-issues]

nebhale opened SPR-10949 and commented

Currently if a method is annotated with @SubscribeEvent and then uses an @PathVariable the value is not mapped into the method invocation. So an example such as the following does not work.

@SubscribeEvent("/projects/{projectId}/builds")
List<Build> onSubscribe(@PathVariable String projectId) {
  ...
}

What should happen is the value that is extracted from the placeholder should be injected in the same way it would be if this were an @RequestMapping annotated method. Note that this means that the argument should be coerced beyond a mere String and should get the full benefit of the Spring's type coercion support (e.g, Spring Data's domain class binding). Also note that this may be more generally applicable to methods annotated with other types (e.g. @MessageMapping).
