Spring MVC Websocket + sockjs https

Question

我在跨域环境中使用spring MVC ws实现WebSocket。我使用HTTP成功测试但是遇到了https的问题。

WebSocket connection to 'wss://server:port/ws/650/vmm0vcx2/websocket' failed: Error during WebSocket handshake: Unexpected response code: 400 stomp.js:10 
Whoops! Lost connection to undefined 

var socket = new SockJS('wss//server:port/ws');
stompClient = Stomp.over(socket);
        stompClient.connect({}, function(frame) {
            console.log('Connected: ' + frame);
            stompClient.subscribe('/topic/datafile', function(response){
                var json = JSON.parse(response.body);
                console.log(json);
            });
        });

春季配置：

<websocket:message-broker application-destination-prefix="/fieldmetrics-api">
        <websocket:stomp-endpoint path="/ws" allowed-origins="*">
            <websocket:sockjs/>
        </websocket:stomp-endpoint>
        <websocket:simple-broker prefix="/topic"/>
    </websocket:message-broker>

我为servlet和过滤器设置了<async-supported>true</async-supported>。 我是websocket的新手，请帮助。
