在Spring4 + STOMP + SockJS应用程序中配置外部代理(RabbitMQ)

我正在使用Spring4 Messaging开发的聊天应用程序和使用SockJS实现的STOMP.我使用Simple Message Broker时应用程序正常工作:

config.enableSimpleBroker("/queue/", "/topic/");

但是,现在我们需要使用具有相同应用程序的外部代理(RabbitMQ).为此,我用以下内容更改了上面的代码:

// config.enableSimpleBroker("/queue/", "/topic/");
config.enableStompBrokerRelay("/queue", "/topic");

我的客户端使用STOMP客户端进行连接,如下所示:

stompClient.connect({},  function(frame) {
    // subscribe to topics or queues and other stuff
});

但是,我得到以下异常:

我检查了RabbitMQ,它已启动并运行.该STOMP插件也被安装在RabbitMQ.I做工精细也试过如下:

1. config.enableStompBrokerRelay("/queue", "/topic").setSystemLogin("guest").setSystemPasscode("guest");
2. config.enableStompBrokerRelay("/queue", "/topic").setClientLogin("guest").setClientPasscode("guest");
3. config.enableStompBrokerRelay("/queue", "/topic").setRelayHost("localhost").setRelayPort("15672");

我做了很多搜索,但仍然无法解决这个问题.有人可以对此有所了解吗？
