import org.springframework.stereotype.Service;

@Service
public class HospitalSetServiceImpl extends ServiceImpl<HospitalSetMapper, HospitalSet> implements HospitalSetService {

}

controller

 @PostMapping("updateHospitalSet")
    public Result updateHospitalSet(@RequestBody HospitalSet hospitalSet){
