<h1>MQTT Interceptor Example</h1>
|
||||
|
||||
<pre>To run the example, simply type <b>mvn verify</b> from this directory, <br>or <b>mvn -PnoServer verify</b> if you want to start and create the server manually.</pre>
|
||||
|
||||
|
||||
<p>This example shows you how to implement and configure a simple incoming, server-side MQTT interceptor with ActiveMQ Artemis.</p>
|
||||
|
||||
<p>ActiveMQ Artemis allows an application to use an interceptor to hook into the messaging system. All that needs to do is to implement the
|
||||
Interceptor interface, as defined below: </p>
|
||||
<pre class="prettyprint">
|
||||
<code>
|
||||
public interface Interceptor
|
||||
{
|
||||
boolean intercept(final MqttMessage mqttMessage, RemotingConnection connection);
|
||||
}
|
||||
</code>
|
||||
</pre>
|
||||
<p>Once you have your own interceptor class, add it to the broker.xml, as follows:</p>
|
||||
<pre class="prettyprint">
|
||||
<code>
|
||||
<configuration>
|
||||
...
|
||||
<remoting-incoming-interceptors>
|
||||
<class-name>org.apache.activemq.artemis.mqtt.example.SimpleMQTTInterceptor</class-name>
|
||||
</remoting-incoming-interceptors>
|
||||
...
|
||||
</configuration>
|
||||
</code>
|
||||
</pre>
|
||||
|
||||
<p>With interceptor, you can handle various events in message processing. In this example, a simple interceptor, SimpleMQTTInterceptor, is implemented and configured.
|
||||
When the example is running, the interceptor will modify the payload of a sample MQTT message.</p>
|
||||
|
||||
<p>With our interceptor we always return <code>true</code> from the <code>intercept</code> method. If we were
|
||||
to return <code>false</code> that signifies that no more interceptors are to run or the target
|
||||
is not to be called. Return <code>false</code> to abort processing of the packet.</p>
|
||||
