ibatis 中如果想使用的话， 可以用 select 的形式如下：
<resultMap class="BasicLineAttr" id="BasicLineAttrMap" >
<result property="blAttrId" column="BL_ATTR_ID"/>
<result property="attrId" column="ATTR_ID"/>
<result property="required" column="required"/>
<result property="attribute" column="ATTR_ID" select="getAttributeById"/>
</resultMap>
<select id="getAttributeById" parameterClass="long" resultMap="attributeModelMap">
SELECT
ATTR_ID, ATTR_NAME,ATTR_NAME_EN,ATTR_TYPE,REQUIRED,ATTR_VALUES,STATUS
FROM AD_ATTRIBUTE WHERE ATTR_ID = #value#
</select>
<select id="getBaseLineAttrs" parameterClass="map" resultMap="BasicLineAttrMap">
SELECT * FROM BASIC_LINE_ATTRIBUTE
</select>
