topic name造句怎么写

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.

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

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.

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

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.
