我使用 spring+stomp 向 websocket 客户端广播消息，但我怎么知道结果是成功的？我使用setSendTimeout方法并捕获异常来检测convertAndSend是否成功，但是没有用！代码

@Resource
private SimpMessagingTemplate simpMessagingTemplate;

@RequestMapping("/test")
public String test() {
    simpMessagingTemplate.setSendTimeout(1);
    String result;
    try {
        simpMessagingTemplate.convertAndSend("/topic/test", "haha");
        result = "success!";
    } catch (Exception e) {
        result = "failed! \n" + e.toString();
    }
    return result;

}

js代码

<script src="/lib/websocket/sockjs.min.js"></script>
<script src="/lib/websocket/stomp.min.js"></script>
<script>
  var socket = new SockJS("/kefu");
  var client = Stomp.over(socket);
  client.debug = function (str) {
  };

  client.connect(
          {},
          function () {
            client.subscribe('/topic/test', function(msg) {
              console.log(msg);
            });
          },
          function (error) {
            console.log(error);
          }
  );

</script>
