mapper中的定义

public interface MenuMapper extends BaseMapper<Menu> {

    /**
     * 根据用户Id 查询用户列表
     * @param id
     * @return
     */
    List<Menu> getMenusByAdminid(Integer id);
}

mapper.xml

<!--根据用户id查询菜单列表-->
    <select id="getMenusByAdminid" resultMap="Menus" >
    SELECT DISTINCT
    m1.*,
    m2.id AS id2,
    m2.url AS url2,
    m2.component AS component2,
    m2.`name` AS name2,
    m2.iconCls As iconCls2,
    m2.keepAlive AS keepAlive2,
    m2.requireAuth AS requireAuth2,
    m2.parentId AS parentId2,
    m2.enabled AS enabled2
    FROM
    t_menu m1, t_menu m2,t_admin_role ar,t_menu_role mr WHERE m1.id = m2.parentId
    AND
    m2.id = mr.mid
    AND
    mr.rid = ar.rid
    AND
    ar.adminId = #{id}
    AND m2.enabled = TRUE
    </select>

请问这要做怎么解决呀

盲猜XML指定的Mapper类写错了
