HornetQ 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.
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 11.1.64, “Topic Hierarchy”.
