mybatis使用中类属性名和数据库表字段名问题

起初我以为上述二者必须一致，后来发现也是可以像Hibernate那样在xml文件中进行映射的。

<mapper namespace="com.tenghu.mybatis.model.xml.DepartmentMapper">  

    <!-- 配置映射字段 -->
    <resultMap type="Department" id="tab_department">
        <id property="ids" column="ids"/>
        <result property="deName" column="de_name"/>
        <result property="pIds" column="p_ids"/>
        <result property="deChargePerson" column="de_charge_person"/>
        <result property="createTime" column="create_time"/>
    </resultMap>  

    <!-- 查询所有部门 -->
    <select id="queryAllDepartment" resultMap="tab_department">
        select * from tab_department
    </select>
</mapper>
