AWS ElasticBeanstalk中的Websocket Tomcat＆amp;春天不工作

Question

我在AWS EB中使用Tomcat。我使用Spring引导开发了一个带有技术栈Spring 4和Java 8的应用程序。我的应用程序使用Spring WebSocket向用户发送通知。以下是javascript条目

<script src="https://cdnjs.cloudflare.com/ajax/libs/sockjs-client/1.1.4/sockjs.min.js" ></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/stomp.js/2.3.3/stomp.min.js" ></script>

// Create and init the SockJS object
var socket = new SockJS('/partnervestcrm/message');
var stompClient = Stomp.over(socket);
// Subscribe the '/notify' channell
stompClient.connect({}, function(frame) {
  stompClient.subscribe('/user/queue/notify', function(notification) {
    // Call the notify function when receive a notification
    //notify(JSON.parse(notification.body).message);
    notify(JSON.parse(notification.body));
  });


}, function(error) {
    alert("STOMP error " + error);
});

当部署到AWS EB时，我在本地工作正常，我收到的错误

WebSocket connection to 'ws://xxxxx/notification/298/plu4ia32/websocket' failed: Error during WebSocket handshake: Unexpected response code: 400

你能告诉我如何解决这个问题吗？
