使用mybatisPlus修改数据-示例

import com.atguigu.yygh.model.hosp.HospitalSet;
import com.baomidou.mybatisplus.core.mapper.BaseMapper;

public interface HospitalSetMapper extends BaseMapper<HospitalSet> {
}

import com.atguigu.yygh.model.hosp.HospitalSet;
import com.baomidou.mybatisplus.extension.service.IService;

public interface HospitalSetService extends IService<HospitalSet> {
}

import com.baomidou.mybatisplus.extension.service.impl.ServiceImpl;
import org.springframework.stereotype.Service;

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

}

 @PostMapping("updateHospitalSet")
    public Result updateHospitalSet(@RequestBody HospitalSet hospitalSet){
        boolean flag = hospitalSetService.updateById(hospitalSet);

        return flag ? Result.ok() : Result.fail();
    }
