amazon-web-services - AWS ElasticBeanstalk Tomcat 和 Spring 中的 Websocket 无法正常工作

Question

我在 AWS EB 中使用 Tomcat。我开发了一个应用程序，使用 Spring boot 技术堆栈 Spring 4 和 Java 8。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，这在我的本地运行良好，但出现以下错误

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？

为安全组添加入站规则解决了这个问题。请在 ec2 dashboard > NETWORK & SECURITY(在左 Pane 中)> security groups > inbound 添​​加规则
