uniRequest.post('/orderParking',{parkingRecord:this.ParkingRecord})

我刚开始只是写@RequestBody ParkingRecord parkingRecord
一直获取的都是null,
直到用了Map标签才终于获取到参数了

 @RequestMapping(value = "/orderParking",produces="application/json",method = RequestMethod.POST)public R orderParking(@RequestBody Map<String,ParkingRecord> parkingRecord)

获取到map的key，就可以获取值了

 @RequestMapping(value = "/orderParking",produces="application/json",method = RequestMethod.POST)public R orderParking(@RequestBody Map<String,ParkingRecord> parkingRecord){System.out.print(parkingRecord.toString());//获取当前时间Date date = new Date();String nowTime = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(date);Timestamp timestamp = Timestamp.valueOf(nowTime);ParkingRecord parkingRecord1 = parkingRecord.get("parkingRecord");parkingRecord1.setStartTime(timestamp);boolean res = parkingRecordService.save(parkingRecord1);Map<String, Object> map = new HashMap<>();map.put("res",res);map.put("mes","预约成功");return R.ok(map);}

有人说是前后端参数名称不一致：在实体类的属性上加一个注解
然而这个没有解决我的问题

@JsonProperty(value = "car_license")private String carLicense;

也有人说是因为lombok的问题,自己用idea的快捷键生成，但也没有解决,
再就是实体类的属性名不符合java规范问题：我刚开始是car_lincese这样命名，都需要改为驼峰式命名，carLinces
