Routing Messages With Wild Cards

ActiveMQ allows the routing of messages via wildcard addresses.

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

Note

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

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

For more information on the wild card syntax take a look at ? chapter, also see ?.
