先贴个逆向工程出来的mapper

/**
* Created by Mybatis Generator 2018/07/15 14:14
*/
public interface EmployeeMapper {
    long countByExample(EmployeeExample example);

    int deleteByExample(EmployeeExample example);

    int deleteByPrimaryKey(Long id);

    int insert(Employee entity);

    int insertSelective(Employee entity);

    List<Employee> selectByExample(EmployeeExample example);

    Employee selectByPrimaryKey(Long id);

    int updateByExampleSelective(@Param("record") Employee record, @Param("example") EmployeeExample example);

    int updateByExample(@Param("record") Employee record, @Param("example") EmployeeExample example);

    int updateByPrimaryKeySelective(Employee entity);

    int updateByPrimaryKey(Employee entity);
}

想知道这些多出来的方法有什么用吗 ? 想要花一分钟学会这个骚操作吗 , 点下面链接直达教程哈哈哈
