To run the example, simply type mvn verify from this directory, or mvn -PnoServer verify if you want to start and create the broker manually.
Using ActiveMQ 5.x virtual topics, messages that are sent to a virtual topic can be consumed from a set of backing queues. This is similar to using an Artemis Address with a multicast binding and consuming from directly from the underlying queue using a FQQN (Fully Qualified Queue Name).
In ActiveMQ 5.x the relation between the virtual topic and its backing queues is established by following a naming convention. For more details on Virtual Topics please see http://activemq.apache.org/virtual-destinations.html
This example shows you how to map a virtual topic naming convention (from ActiveMQ 5.x) to use the Artemis Address model . The Artemis broker is configured to recognise the Virtual Topic Naming convention, using virtualTopicConsumerWildcards acceptor parameter and the consumer will be mapped internally to consume from the appropriate FQQN rather than the specified Address.
The example sends a message to a topic (using openwire protocol) and an openwire consumer listens on the backing queue using the ActiveMQ 5.x virtual topic naming convention. Due to the acceptor url parameter virtualTopicConsumerWildcards, (see below), Artemis maps the consumer consuming from Consumer.A.VirtualTopic.Orders to actually consume from FQQN of VirtualTopic.Orders::Consumer.A.VirtualTopic.Orders
<acceptor name="artemis">tcp://0.0.0.0:61616?virtualTopicConsumerWildcards=Consumer.*.%3E%3B2</acceptor>
