Question

我配置了独立的hornetq并启动了它。创建了一个发送方类和一个MDB接收方类。当我使用该方法向消费者类注册我的发件人类时， messageConsumer.setMessageListener（listener）在sender类本身，它工作正常。但是当我在jboss应用服务器中部署我的MDB接收器（.war文件！）时，它不会监听队列消息。

你的问题没有很好地阐述，但让我试试......

为了给你一个正确的答案，我需要更多的信息，你的服务器在哪里（它是远程的），以及你正在使用的版本。

通常，您只需指定远程服务器即可。你有关于HornetQ文档的一些信息：

http://docs.jboss.org/hornetq/2.2.2.Final/user-manual/en/html/appserver-integration.html#d0e8389

如果您向我提供有关正在发生的事情的更多信息（错误，版本），我可能会尝试给您更好的答案。
