Annotation Interface MessageInterceptor

@Target(METHOD) @Retention(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&lt;String&gt; 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.
