Java 如何在IBatis的select查询中发送列表？

我正在使用Java1.7、IBatis和postgreSQL

我有一个学生

My函数返回以下结果：

从获取参与方详细信息1102103104中选择*

My querys.xml

有什么帮助/建议吗

编辑1：我也尝试了foreach循环，但这并没有让我摆脱这个问题

<select id="get_party_details" parameterType="StudentVO" statementType="PREPARED" resultMap="partyMap">
        select * from get_party_details(
        <foreach item="friends" index="index" collection="studentFriendNums"
            open="(" separator="," close=")">
            #{friends}
        </foreach>
        )
    </select>

编辑2：我的Ibatis版本是3.2.3

您可以尝试使用iterate标记：

您可以使用foreach：

   <select id="get_party_details" parameterType="StudentVO" 
            statementType="PREPARED" resultMap="partyMap">
                select * from get_party_details
                <foreach item="item" index="index" collection="studentFriendNums"
                    open="(" separator="," close=")">
                #{item}
               </foreach>
    </select>

---

刚刚看到您的第一次编辑，您不需要在foreach前后打开和关闭括号。参数打开和关闭为您执行此操作。

这是我的错！我只是看过头了！谢谢：使用Iterate给了我一个警告，因为元素类型select的内容必须匹配include | trim | where | set | foreach | choose | if | bind。您使用的是哪个版本的ibatis？您可以发送完整的sqlMap文件吗？org.mybatis mybatis 3.2.3我想mybatis已经取消了对的支持。很抱歉，你可以用标签代替迭代。酷！无论如何，谢谢你的回答！：
