后台代码：

@RequestMapping(value = "getServerDevice")
        @ResponseBody
        public String getServerDevice(
                HttpServletRequest request,
                HttpServletResponse response,
                @ModelAttribute ServerDevice inputData,
                ModelMap modelMap){
            String siteCode = inputData.getSiteCode();
            List<ServerDevice> serverDeviceList = serverDeviceService.getResultBySiteCode(siteCode);
            Gson gson = new Gson();
            String retString = gson.toJson(serverDeviceList);
            System.out.println(retString + "aaaaaa");
            return retString;
        }

json数据：

[{"deviceId":"5c4b907fb722413b801728f39eb5885e","siteCode":"1","siteName":"明尼苏达小区","localDeviceId":5,"localUploadDate":"Jun 24, 2019 4:00:00 PM","deviceAlarm":"null","deviceAlarmNum":0,"serverThemoList":[],"serverWaterList":[],"serverSmokeList":[],"serverHumidityList":[],"deviceNum":4,"deviceStatus":"OK","deviceAlarmLevel":1,"createdDate":"Jun 24, 2019 4:00:37 PM"}]aaaaaa

前台ajax代码：

$.ajax({
                    type : "post",
                    url : projectName + "/sensors/mobile/getServerDevice",
                    data : inputData,
                    dataType : "json",
                    async : false,
                    success: function (data)
                    {
                        var obj = JSON.parse(data);
                        console.log(obj[0].deviceAlarmLevel + "   dddd");//根据实际业务需求，改为遍历读取即可。
                    }
    });
