WebSocket握手-意外的响应代码200-AngularJs和Spring Boot

Question

当我尝试在AngularJS应用和Spring Boot之间建立websocket通信时，出现错误：websocket握手期间出错-意外的响应代码：200。

这是我的JS代码：

function run(stateHandler, translationHandler, $websocket) {
    stateHandler.initialize();
    translationHandler.initialize();

    var ws = $websocket.$new('ws://localhost:8080/socket'); // instance of ngWebsocket, handled by $websocket service

    ws.$on('$open', function () {
        console.log('Oh my gosh, websocket is really open! Fukken awesome!');  
    });

    ws.$on('/topic/notification', function (data) {
        console.log('The websocket server has sent the following data:');
        console.log(data);

        ws.$close();
    });

    ws.$on('$close', function () {
        console.log('Noooooooooou, I want to have more fun with ngWebsocket, damn it!');
    });
}

这是我的Java代码：

WebsocketConfiguration.java

@Override
public void registerStompEndpoints(StompEndpointRegistry stompEndpointRegistry)
{
    stompEndpointRegistry.addEndpoint("/socket")
        .setAllowedOrigins("*")
        .withSockJS();
}

@Override
public void configureMessageBroker(MessageBrokerRegistry registry) {
    registry.enableSimpleBroker("/topic");
}

WebsocketSecurityConfiguration.java

@Override
protected void configureInbound(MessageSecurityMetadataSourceRegistry messages) {
    messages
        // message types other than MESSAGE and SUBSCRIBE
        .nullDestMatcher().authenticated()
        // matches any destination that starts with /rooms/
        .simpDestMatchers("/topic/tracker").hasAuthority(AuthoritiesConstants.ADMIN)
        .simpDestMatchers("/topic/**").permitAll()
        // (i.e. cannot send messages directly to /topic/, /queue/)
        // (i.e. cannot subscribe to /topic/messages/* to get messages sent to
        // /topic/messages-user<id>)
        .simpTypeMatchers(SimpMessageType.MESSAGE, SimpMessageType.SUBSCRIBE).denyAll()
        // catch all
        .anyMessage().denyAll();
}

有谁知道如何解决这个问题？
先感谢您！

我有一个类似的问题，我正在使用chrome插件（简单的WebSocket客户端）测试我的Websocket连接，并尝试连接到我的代码中定义的ws：// localhost：8080 / handler /， registry.addEndpoint("/handler").setAllowedOrigins("*").withSockJS();但发生了意外错误200 。我已通过将/ websocket附加到chrome扩展程序上的客户端请求字符串中来解决此问题，因此您可以尝试在JS文件中更改以下行：

var ws = $websocket.$new('ws://localhost:8080/socket');

至

 var ws = $websocket.$new('ws://localhost:8080/socket/websocket');

我不知道为什么在我的情况下解决这个问题，我只是偶然发现了它，如果some1可以进一步阐明它，那将是非常好的:)

你可以尝试这个WebsocketConfiguration配置：

@Override
public void registerStompEndpoints(StompEndpointRegistry stompEndpointRegistry)
{
    stompEndpointRegistry.addEndpoint("/socket").setAllowedOrigins("*");      
    stompEndpointRegistry.addEndpoint("/socket").setAllowedOrigins("*").withSockJS();
}

那么你有 websocket 和 SockJS 配置吗？
