mybatis 多级级联问题

Question

在mybatis里面

当有三张表 o,u,ui 我想用o表查到ui的数据

返回类型是 o 时 ，这个resultMapper 改怎么写呢？
下面这个mapper 的写法是对的吗？

 select o.* ,ui.id as ui_id,ui.name as ui_name from order o, u_user u LEFT JOIN u_userinfo ui ON u.`id`=ui.`user_id`
 where  o.user_id = u.id 

 <resultMap id="fuckJiLianResult" type="com.ronhan.ctoc.model.Review">
    <id column="id" jdbcType="BIGINT" property="id" />

    <result column="user_id" jdbcType="BIGINT" property="userId" />
    <result column="score1" jdbcType="TINYINT" property="score1" />
    <result column="score2" jdbcType="TINYINT" property="score2" />
    <result column="score3" jdbcType="TINYINT" property="score3" />
    <result column="comments" jdbcType="VARCHAR" property="comments" />

      <association column="user" property="user" javaType="com.ronhan.ctoc.model.User" resultMap="userResult"/>
     </collection>
     </resultMap>
       <resultMap id="userResult" type="com.ronhan.ctoc.model.User">
        <id column="id" jdbcType="BIGINT" property="id" />
         <association column="userInfo" property="userInfo" javaType="com.ronhan.ctoc.model.UserInfo" resultMap="userInfoResult"/>
    </resultMap>
    <resultMap id="userInfoResult" type="com.ronhan.ctoc.model.UserInfo">
    <id column="ui_id" jdbcType="BIGINT" property="id" />

    <result column="ui_name" jdbcType="VARCHAR" property="name" />

    <result column="ui_buys" jdbcType="Integer" property="buys" />
  </resultMap>

MyBatis不需要指定对应关系，只需查询的字段名和JavaBean属性名对应即可，Hibernate才要这样指定。
