Mybatis 传入List类型参数，报错：There is no getter for property named '__frch_item_0' in

错误如下：

org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.ibatis.reflection.ReflectionException: There is no getter for property named '__frch_item_0' in 'class com.asiacloud.core.model.PageModel'

at com.asiacloud.syse.unitaccount.dao.impl.TSyseMaintainAccountDaoImpl.queryListByUnitIdPage(TSyseMaintainAccountDaoImpl.java:107)

Mapper

<select id="queryListByUnitIdPage" parameterType="TSyseMaintainAccount" resultMap="TSyseMaintainAccountResultMap">
        select a.*,b.UNIT_NAME linkUnitName from T_SYSE_MAINTAIN_ACCOUNT a
        left JOIN T_SYSE_OPER_UNIT b
        on a.UNIT_ID=b.ID
        where a.STATUS_FLAG in ('1','2')
        AND a.UNIT_ID in  
            <foreach item="item" index="index" collection="params.idList" open="(" separator="," close=")">  
                       #{item}  
            </foreach> 
        AND a.ID != #{params.id}
    </select>

上面写法错误，注意下面foreach中的值取法，如果取的是List，要用索引来取。

<foreach item="item" index="index" collection="params.idList" open="(" separator="," close=")">  
    #{params.idList[${index}]}
</foreach>
