<h1>Topic Hierarchy Example</h1>
|
|
|
|
<pre>To run the example, simply type <b>mvn verify</b> from this directory, <br>or <b>mvn -PnoServer verify</b> if you want to start and create the server manually.</pre>

|
<p>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.</p>
|
|
<p>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 "."</p>
|
|
<p>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"</p>
|
|
<p>For more information on the wild-card syntax please consult the user manual.</p>
