AMQP Interceptor Example

To run the example, simply type mvn verify from this directory, or mvn -PnoServer verify if you want to start and create the broker manually.

This example shows you how to implement and configure a simple incoming, server-side AMQP interceptor with ActiveMQ Artemis.

ActiveMQ Artemis allows an application to use an interceptor to hook into the messaging system. To intercept AMQP packets all that needs to be done is to implement the org.apache.activemq.artemis.protocol.amqp.broker.AmqpInterceptor interface.

Once you have your own interceptor class add it to the broker.xml as follows:

<core>
   ...
   <remoting-incoming-interceptors>
      <class-name>org.apache.activemq.artemis.amqp.example.SimpleAmqpInterceptor</class-name>
   </remoting-incoming-interceptors>
    ...
</core>

With an interceptor you can handle various events in message processing. In this example, a simple interceptor, SimpleAmqpInterceptor, is implemented and configured. When the example is running, the interceptor will display the value of a string property of a sample AMQP message.

With our interceptor we always return true from the intercept method. If we were to return false that signifies that no more interceptors are to run. Throw an exception to abort processing of the packet.
