Annotation Interface Topic

@Documented @Retention(RUNTIME) @Target({TYPE,METHOD,PARAMETER}) @Repeatable(Topics.class) @Bindable @Executable @Inherited public @interface Topic
Used for binding the message topic and other parameters. Use multiple annotations to subscribe to multiple topics. When used on a subscriber, any topic annotations from the class level will be used in addition to any annotations found on the method level. Only one instance of the annotation can be applied to publishers because publishers cannot publish to multiple topics.
