websocket连接不会与stompjs和spring boot关闭

我有websocket的问题我正在使用spring boot和stompjs我正在使用以下代码订阅套接字：

var socketLien = /*[[@{'/socket'}]]*/;
var socket = new SockJS(socketLien);
var stompClient = Stomp.over(socket);
stompClient.reconnect_delay = 5000;
stompClient.connect({}, function (frame) {

    var lien = /*[[${"/topic/greetings"}]]*/;
    var agenceId =/*[[${session.agencePrincipale.id}]]*/
    var cessionLien = /*[[@{'/Agence/Cession/Creation'}]]*/; 

    stompClient.subscribe(lien+"/"+agenceId, function (greeting) {
        notif(jQuery.parseJSON(greeting.body),cessionLien);
    },{"agenceId" : agenceId});
    /*]]>*/

    stompClient.subscribe("/user"+lien+"/"+agenceId, function (greeting) {
       console.log(greeting.body);
       notif(jQuery.parseJSON(greeting.body),cessionLien);
    });
},function(frame) {
    console.log('close');
    stompClient.disconnect();
});

刷新后，会创建一个新连接，但旧连接不会关闭

我在服务器中找到了一个日志，显示所有已连接的套接字

[MessageBroker-1] o.s.w.s.c.WebSocketMessageBrokerStats    : WebSocketSession[0 current WS(0)-HttpStream(0)-HttpPoll(0), 11 total, 0 closed abnormally (0 connect failure, 0 send limit, 0 transport error)], stompSubProtocol[processed CONNECT(11)-CONNECTED(11)-DISCONNECT(0)], stompBrokerRelay[null], inboundChannel[pool size = 0, active threads = 0, queued tasks = 0, completed tasks = 132], outboundChannelpool size = 0, active threads = 0, queued tasks = 0, completed tasks = 22], sockJsScheduler[pool size = 4, active threads = 1, queued tasks = 9, completed tasks = 29198]

这是我在 Spring 季靴子的conf：

@Configuration
@EnableWebSocketMessageBroker
public class WebSocketConfig extends AbstractWebSocketMessageBrokerConfigurer{

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

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

你能帮助我吗 ？
