上传json

代码实现

@RestController
@RequestMapping("/api/hosp")
public class ApiController{@Autowiredprivate HospitalService hospitalService;@PostMapping("saveHospital")public Result saveHosp(HttpServletRequest request){Map<String,String[]> parameterMap = request.getParameterMap();//调用工具进行类型转换Map<String,Object> paramMap = HttpRequestHelper.switchMap(requestMap);//调用service方法，添加到数据库hospitalService.save(paramMap);return Reult.ok();}
}

@Service
public class HospitalServiceImpl implements HospitalService{@Autowiredprivate HospitalRepository hospitalRepository;@Overridepublic void save(Map<String,Object> paramMap){//通过fastjson工具进行对参数的转换String mapString = JSONObject.toJSONString(paramMap);Hospital hospital = JSONObject.parseObject(mapString,Hospital.class);//判断是否存在数据String hoscode = hospital.getHoscode();Hospital hospitalExist = hospitalRepository.getHospitalByHoscode(hoscode);//如果不存在，进行添加，否则修改if(hospitalExist != null){hospital.setStatus(hospitalExist.getStatus());hospital.setCreateTime(hospitalExist.getCreateTime());hospital.setUpdateTime(new Date());hospital.setIsDeleted(0);hospitalRepository.save(hospital);}else{hospital.setStatus(0);hospital.setCreateTime(new Date());hospital.setUpdateTime(new Date());hospital.setIsDeleted(0);hospitalRepository.save(hospital);}}
}

@Repository
public interface HospitalRepository extends MongoRepository<Hospital,String>{//判断是否存在数据Hospital getHospitalByHoscode(String hoscode);
}

工具

/**将map集合的value,由String数组类型转为Object类型
*/
public static Map<String,Object> switchMap(Map<String,String[]> paramMap){Map<String,Object> resultMap = new HashMap<>();for(Map.Entry<String,String[]> param:paramMap.entrySet()){resultMap.put(param.getKey(),param.getValue()[0]);}return resultMap;
}

/**引入依赖fastjson，进行如下转换将Map->字符串->对象
*/
