Mybatis 的foreach 可以嵌套吗？

1. ​​http://code.google.com/p/mybatis/source/browse/trunk/src/test/java/org/apache/ibatis/submitted/nested/?r=3467​​

1. 
2. Junit Test
3. NestedForEachTest.java
4. NestedForEach.xml

照着这个效果,我在自己的paohe项目xml中这样写

<select id="queryQualityCost" parameterType="com.itonghui.biz.qualityclient.model.QualityClient" resultMap="BaseResultMap">
 SELECT 
 <include refid="Base_Column_List" />
 FROM spot_quality_cost
       WHERE QUALITY_COST_ID IN
 <foreach collection="qualitySampleinfoList" item="qualitySampleinfo" open="(" separator="," close=")"  >
 <foreach collection="qualitySampleinfo.qualityVarietyList" item="qualityVariety" separator="," >
 #{qualityVariety.qualityCostId}
     </foreach>
 </foreach>
 </select>java代码:
QualityClientServiceImpl.java:
QualityClient qualityClient = new QualityClient();
 qualityClient.setQualitySampleinfoList(sampleInfoListTmp);
 List<QualityCost> qualityCostList = qualityCostMapper.queryQualityCost(qualityClient); //获取最新的检测项费用

其中QualityClient.java   vo类有 private List<QualitySampleinfo> qualitySampleinfoList; //样品列表,

QualitySampleinfo.java vo类有 private List<QualityVariety> qualityVariety;

最终sql效果是

SELECT QUALITY_COST_ID, QUALITY_DESC_ID, QUALITY_CHECK_ID, INSPECT_ORGANIZATION
 _ID, TESTING_COST, CHECK_TYPE, IS_STANDARD_SAMPLE, REMARK, ALIVE_FLAG FROM spot_quality_cost WHERE QUALITY_COS
 T_ID IN ( ? , ? , ? , ? , ? , ? )

mybatis多个foreach嵌套查询成功!
