public class AnnotatedMessageHandlingMemberDefinition extends Object implements HandlerDefinition
For this implementation to recognize a handler method, it should be (meta)annotated with MessageHandler
. It
is recommended to meta-annotated members, and preconfigure the expected messageType
. For example, and event
handler should define @MessageHandler(messageType = EventMessage.class)
, indicating that this handler should
only be invoked for EventMessage
s.
