前端代码

initWebSocket(){ //初始化weosocket

        const wsuri = "ws://localhost:8090/websocket/ws";//ws地址
        this.websock = new WebSocket(wsuri);
        this.websocket.onopen = this.websocketonopen;

        console.log("WebSocket连接发生错误");
      },
      websocketonmessage(e){ //数据接收
        const redata = JSON.parse(e.data);
        //注意:长连接我们是后台直接1秒推送一条数据,
        //但是点击某个列表时,会发送给后台一个标识,后台根据此标识返回相对应的数据,
        //这个时候数据就只能从一个出口出,所以让后台加了一个键,例如键为1时,是每隔1秒推送的数据,为2时是发送标识后再推送的数据,以作区分
        console.log(redata.value);
      },

      websocketsend(agentData){//数据发送
        this.websock.send(agentData);

      websocketclose(e){ //关闭
