Apache ActiveMQ Artemis 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.
|
In JMS terminology this allows "topic hierarchies" to be created. |
This functionality is enabled by default.
To turn it off add the following to the broker.xml configuration.
<wildcard-addresses>
<routing-enabled>false</routing-enabled>
</wildcard-addresses>For more information on the wild card syntax and how to configure it, take a look at wildcard syntax chapter, also see the topic hierarchy example in the examples.
