Mybatis下配置调用Oracle自定义函数返回的游标结果集

在ibatis和Mybatis对存储过程和函数函数的调用的配置Xml是不一样的，以下是针对Mybatis 3.2的环境进行操作的。

• 第一步配置Mapper的xml内容

<mapper namespace="com.rrtong.rrt.auto.dao.SelfStatisticDataDao">
 	<resultMap id="SelfStatisticData" type="SelfStatisticData">
        <id 	column="name" 	property="name" />
        <result column="count" 	property="count"/>
    </resultMap>

	<select id="getSelfStatisticData" parameterType="HashMap" statementType="CALLABLE" >
 	    {#{result,mode=OUT,jdbcType=CURSOR, resultMap=SelfStatisticData} = call PKG_RRT_SelfStatics.Fn_GetSelfStatData(#{userCode,jdbcType=VARCHAR,mode=IN})	}
	</select>
</mapper>

说明：

1、result对应的是oracle自定义函数返回的游标

2、映射对象resultMap对应的是SelfStaticData

3、userCode为传入参数

• 在Service层中如何得到该游标的数据集呢？下面为调用实例，

@Service
public class SelfStatisticDataServiceImpl implements SelfStatisticDataService{
	@Resource
	SelfStatisticDataCache selfStatisticDataCache;

	public List<?> getSelfStatisticData(String userCode){
		List<?> selfStaticDataList = new ArrayList<Map<String,Object>>();
		HashMap<String,Object> statMap = new HashMap<String,Object>();
		statMap.put("userCode", userCode);
                /*设定游标结果写入的变量*/
                statMap.put("result", selfStaticDataList);	

		selfStatisticDataCache.getSelfStatisticData(statMap);
		/*获取返回的游标结果集*/
                selfStaticDataList = (List<?>) statMap.get("result");	

		return selfStaticDataList;
	}
}
