java - Avoiding duplicated messages on JMS/ActiveMQ

Question

Is there a way to suppress duplicated messages on a queue defined on ActiveMQ server?

I tried to define manually JMSMessageID, (message.setJMSMessageID("uniqueid")), but server ignores this modification and deliver a message with built-in generated JMSMessageID.

By specification, I didn't found a reference about how to deduplicate messages.

In HornetQ, to deal with this problem, we need to declare the HQ specific property org.hornetq.core.message.impl.HDR_DUPLICATE_DETECTION_ID on message definition.

i.e.:

Message jmsMessage = session.createMessage();
String myUniqueID = "This is my unique id"; // Could use a UUID for this
message.setStringProperty(HDR_DUPLICATE_DETECTION_ID.toString(), myUniqueID);

Somebody knows if there's a similar solution for ActiveMQ?

Answer 1

You should look at Apache Camel, it provides an Idempotent consumer component that would work with any JMS provider, see: http://camel.apache.org/idempotent-consumer.html

Using that in combination with the ActiveMQ component makes using JMS quite simple, see: http://camel.apache.org/activemq.html
