Javascript 如何与spring websocket通信

我正在尝试构建一个应用程序，在这个应用程序中，服务器将在某个时间间隔内不断向客户端推送消息。 我有这样一个简单的html文件

    <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.4/angular.min.js"></script>
<script src="sockjs/sockjs.js"></script>
<script src="stomp/stomp.js"></script>
<div ng-app="myApp" ng-controller="myCtrl">
<button ng-click='connect()'>hi</button>
</div>

<script>
var app = angular.module('myApp', []);

app.controller('myCtrl', function($scope) {
    $scope.connect = function() {
        var socket = new SockJS('http://localhost:8099/myws');
        $scope.stompClient = Stomp.over(socket);
        $scope.stompClient.connect({}, function (frame) {
            console.log('Connected:bhabani ' + frame);
            $scope.stompClient.subscribe('http://localhost:8099/topic/jobconfig', function (wsdata) {
                console.log("helloooooooooooooooooooooooooooooooooooooooooooooooooo");
                console.log(wsdata);
            });
        });
    }
});
</script>

@Configuration
@EnableWebSocketMessageBroker
public class WebSocketConfig extends AbstractWebSocketMessageBrokerConfigurer {

    @Autowired
    private GreetingController gc;

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

    @Override
    public void registerStompEndpoints(StompEndpointRegistry registry) {
        registry.addEndpoint("/myws").setAllowedOrigins("*").withSockJS();
        new Thread(gc).start();
    }

}

有一个像这样的问候控制器，它应该以某种内部方式将消息推送到主题

@Component
public class GreetingController implements Runnable{

    @Autowired
    private SimpMessagingTemplate template;

    public void run() {
        try {
            Thread.sleep(10000);
        } catch (InterruptedException e1) {
            // TODO Auto-generated catch block
            e1.printStackTrace();
        }
        while(true){
        try {
            System.out.println("Sending");
            Thread.sleep(1000);
            template.convertAndSend("/topic/jobconfig", new Greeting("hi"));
        } catch (Exception e) {
            e.printStackTrace();
        }
        }
    }

当我按下连接按钮时，我可以看到连接已建立。 但是在那之后，我没有看到任何应该从服务器推送的消息出现在浏览器中

---

我希望“helloooo”消息应该在每个时间间隔打印在我的浏览器控制台中。

从此

更改stomp客户端订阅代码中的URLhttp://localhost:8099/topic/jobconfig

至此

/topic/jobconfig

$scope.stompClient.subscribe('/topic/jobconfig', function(wsdata) {
                    console.log("hello");
                    console.log(wsdata);
                });
