java - 如何允许 JMS 使用端口 7676

Question

因此，我在运行使用 JMS 的应用程序时遇到了这个问题，我做了此处描述的所有操作 Transparent Asynchronous Remoting via JMS

这是我收到的异常:

org.springframework.jms.UncategorizedJmsException: Uncategorized exception occured during JMS processing; nested exception is com.sun.messaging.jms.JMSException: [C4003]: Error occurred on connection creation [localhost:7676]. - cause: java.net.ConnectException: Connection refused: connect

我绝对没有 JMS 或 Camel 的经验，所以我猜 JMS 不允许使用端口 7676，如果是的话，我该如何解决这个问题？如果这不是原因，您是否有任何提示我做错了什么？

Answer 1

您有在此端口上运行的代理吗？您可以验证代理是否正在使用 telnet 运行:

telnet localhost 7676
