mybatis的XML递归获取子菜单

XML中：

<!--递归获取子类-->
<resultMap id="BaseResultMap" type="easy.quick.entity.operation.bean.Menu">
    <id property="id" column="id" />
    <result column="name" property="name" />
    <result column="parentId" property="parentId" />
    <result column="isParent" property="isParent" />
    <collection property="children" ofType="easy.quick.entity.operation.bean.Menu"
        select="easy.quick.user.dao.MenuDao.getMenuList" column="id"></collection>
</resultMap>

<select id="getYYMenuList" resultMap="BaseResultMap">
    SELECT * FROM yy_menu  WHERE parentId = #{id}
</select>

Dao中：

/**
 * 菜单列表获取
 * 树状结构展示
 * @param mid
 * @return
 */
List<Menu> getMenuList(@Param("id") long id);
