Annotation Type MessageInterceptor

@Target(value=METHOD)
 @Retention(value=RUNTIME)
 @Documented
public @interface MessageInterceptor

An annotation that marks a method to be used as a MessageInterceptor.

The annotated method must expect a single argument with parameter type TextMessage, or Message<String>. The return type can either be Textmessage, Message<String> or void.

MessageInterceptors can be used as MessageFilter: If the annotated method is returning null, the intercepted message will be dropped, without sending and/or processing it.

Processing of @MessageInterceptor annotations is performed by a MessageInterceptorBeanPostProcessor that is auto-configured in SynapseAutoConfiguration.
