Annotation Type MessageHandlerInterceptor

@MessageHandler
 @Retention(value=RUNTIME)
 @Target(value={METHOD,ANNOTATION_TYPE})
public @interface MessageHandlerInterceptor

Annotation marking an handler method as an interceptor handler. Unlike regular handlers, interceptor handlers are chained and do not block processing by other handlers. They can be used to add processing behavior either before, after or both before and after processing of other handlers.

When parameters of an interceptor do not match the message, this will prevent the invocation of this handler, but it will not block processing of any other handlers that do match.
