mybatis插入数据成功，数据库没有显示

 public int insertFlight(FlightEntity flightEntity){
        int result=flightMapper.insertFlight(flightEntity);
        return result;
    }

修改为

public SqlSession sqlSession;
public int insertFlight(FlightEntity flightEntity){
        int result=flightMapper.insertFlight(flightEntity);
        sqlSession.commit();//需要提交事务
        return result;
    }
