迭代Ibatis中的对象列表 [英] Iterate list of Objects in Ibatis

问题描述

我有一个对象列表，我想迭代并访问ibatis sql中的特定字段。

I have a list of object where I want to iterate and access a particular field in ibatis sql.

Ex。

public Class Student
{
String id;
String name;
}

我将作为参数传递给学生对象列表（列表（学生））

并迭代访问每个对象bean的id。我该怎么做？

I will pass as parameter a List of Student object(List(Student))
and do iteration accessing the id for each object bean. How do I do this?

推荐答案

foreach -tag就是你要找的。示例：

The foreach-tag is what you are looking for. Example:

<select id="selectPostIn" resultType="domain.blog.Post">
  SELECT *
   FROM POST P
   WHERE ID in
   <foreach item="item" index="index" collection="list" open="(" separator="," close=")">
    #{item}
   </foreach>
</select>

参见用户指南了解更多信息，请参见动态sql一章。

See the user guide for more info, chapter "dynamic sql".

顺便说一句，iBatis不再开发并被冻结，它现在被称为MyBatis，整个开发团队从Apache转移到新的MyBatis主页。

By the way, iBatis is no longer developed and is frozen, it is now called "MyBatis" and the whole developer team moved away from Apache to the new MyBatis home.
