Chapter 12. Routing Messages With Wild Cards

HornetQ allows the routing of messages via wildcard addresses.

If a queue is created with an address of say then it will receive any messages sent to addresses that match this, for instance or or If you create a consumer on this queue, this allows a consumer to consume messages which are sent to a hierarchy of addresses.


In JMS terminology this allows "topic hierarchies" to be created.

To enable this functionality set the property wild-card-routing-enabled in the hornetq-configuration.xml file to true. This is true by default.

For more information on the wild card syntax take a look at Chapter 13, Understanding the HornetQ Wildcard Syntax chapter, also see Section 11.1.54, “Topic Hierarchy”.
