2.java

    @RequiresPermissions("system:lmonitor:list")
    @PostMapping("/list")
    @ResponseBody
    public TableDataInfo list(LstMonitor lstMonitor)
    {
        startPage();

        return getDataTable(list);
    }

        var map = new BMap.Map('container');  // 创建地图实例
        var center = new BMap.Point(121.18720385246547,31.28460823015341);  // 设置中心点
        map.centerAndZoom(center, 100);  // 初始化地图， 设置中心点坐标和地图级别
        map.enableScrollWheelZoom(true);  //启用滚轮放大缩小，默认禁用

            var latitude = mapList[i]['latitude'] / resolution;
            var devId = mapList[i]['devId'];
            var opt = {width: 200, height: 100, title: "背景OBU"};  // 创建信息窗口
            points[i] = new BMap.Point(longitude,latitude);  // 设置中心点

                this.openInfoWindow(infoWindow,point);
