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;
}
}
