  • 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 org.mybatis.spring.MyBatisExceptionTranslator.translateExceptionIfPossible(MyBatisExceptionTranslator.java:75)
    at org.mybatis.spring.SqlSessionTemplate$SqlSessionInterceptor.invoke(SqlSessionTemplate.java:368)
    at $Proxy6.selectList(Unknown Source)
    at org.mybatis.spring.SqlSessionTemplate.selectList(SqlSessionTemplate.java:198)
    at com.asiacloud.core.base.dao.impl.BaseDaoImpl.select(BaseDaoImpl.java:74)
    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>
