ActiveMQ Artemis Topic Hierarchy Example

# 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 server 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.
