springboot项目 Feign调用时，@RequestBody 接受字符串(String),json字符串多出引号

今天对外提供接口，接口如下

打印结果如下：  =======mapAlarmVo======JSONObject.toJSONString(mapAlarmVo)=======“{"policeId":"d8e749914fb84492a338a58794f7d098","personTypeName":"嫌疑人","sCaseCode":"210220112240000","alarmTypeName":"无人看管","orgId":"a9d44acdb3d0481f84a1431c24f6772f","sCreateUser":"admin","dtUpdateTime":1613974757773,"policeNameNo":"进程21001","sDescribe":"测试无人看管","policeName":"进程2","id":"a69c8572-d30b-400e-9252-7c021567ba41","personType":"0","sAlarmSourceId":"623c9aa78355435f87c381ae877a41e4","verifiedFlg":"0","alarmTime":1613974627000,"policeNo":"1001","dtCreateTime":1613974757773,"sUpdateUser":"admin","sStandBookId":"108604e0bc8449279a322997cac2479d","alarmArea":"","personName":"测试","alarmType":"100522","alarmAreaName":"","personId":"623c9aa78355435f87c381ae877a41e4","sAlarmSourceName":"测试","sAlarmWeight":"20"} “

收到消息体多了个引号。
