topic name造句

By including wildcards in the topic name of the JMS topic definition, a subscriber can receive messages from multiple topics with a single subscription.

Keep in mind that an application cannot publish to a JMS topic whose topic name contains wildcards, because a publisher can only publish a message to a single topic.

A subscriber (but not a publisher) can specify a topic name that contains wildcard characters, which creates a single subscription to multiple topics, such as a branch in a topic hierarchy.

What is important for your site is that you choose topic names that are meaningful within the context of the topic trees that you will define.

However, this definition does not create a new named object in the program and topic namespaces.
