Topic Hierarchy Example

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.

ActiveMQ Artemis supports topic hierarchies. With a topic hierarchy you can register a subscriber with a wild-card and that subscriber will receive any messages routed to an address that match the wildcard.

ActiveMQ Artemis wild-cards can use the character # which means "match any number of words", and the character * which means "match a single word". Words are delimited by the character ..

For example if I subscribe using the wild-card news.europe.#, then that would match messages sent to the addresses news.europe, news.europe.sport and news.europe.entertainment, but it does not match messages sent to the address news.usa.wrestling.

For more information on the wild-card syntax please consult the user manual.
