Annotation Interface SubscribeMapping

@Target(METHOD) @Retention(RUNTIME) @Documented @Reflective(MessageMappingReflectiveProcessor.class) public @interface SubscribeMapping
Annotation for mapping subscription messages onto specific handler methods based on the destination of a subscription. Supported with STOMP over WebSocket only (for example, STOMP SUBSCRIBE frame).

This is a method-level annotation that can be combined with a type-level @MessageMapping.

Supports the same method arguments as @MessageMapping; however, subscription messages typically do not have a body.

The return value also follows the same rules as for @MessageMapping, except if the method is not annotated with SendTo or SendToUser, the message is sent directly back to the connected user and does not pass through the message broker. This is useful for implementing a request-reply pattern.

NOTE: When using controller interfaces (for example, for AOP proxying), make sure to consistently put all your mapping annotations - such as @MessageMapping and @SubscribeMapping - on the controller interface rather than on the implementation class.

      This is the destination of the STOMP message (for example, "/positions"). Ant-style path patterns (for example, "/price.stock.*") and path template variables (for example, "/price.stock.{ticker}") are also supported.
