iBATIS 查询多个实例的配置 - iBATIS报错

"

ibits查询传入参数和传出参数不是同一个实体的解决方法。

代码如下：

    <typeAlias alias="cmsStatistic" type="com.geong.report.data.CmsStatistic" />
    <typeAlias alias="statistic" type="com.geong.report.data.StatisticObj" />

<!-- 结果集定义 -->
    <resultMap id="ResultMap" class="cmsStatistic">
        <result property="cId" column="c_id"/>
        <result property="cProcessDate" column="c_process_date"/>
        <result property="cProcessType" column="c_process_type"/>
        <result property="cUserid" column="c_userid"/>
        <result property="cItemType" column="c_item_type"/>
        <result property="cItemId" column="c_item_id"/>

     </resultMap>

<!-- 统计结果集定义  人员工作量统计 -->

     </resultMap>

        <isNotEmpty prepend="and" property = "cEndDate">
             cmsStatistic.c_process_date < to_date('#cEndDate#','yyyy-MM-dd')
