public class PfStuffInfoVo implements Serializable {
/** 信息Id */
private String infoId;
/** 项目Id */
private String proid;
/** 附件信息 */
private List<PfFileVo> fileList;
...
这是我的对象 该怎么把fileList属性已插入，PfFileVo 有对应的表
貌似iBatis没有提供多个关联对象的同时插入
你需要再Service层调用多个DAO去做多个关联对象的插入操作
批处理在iBatis里是肯定有的
貌似叫batchUpdate方法
不记得了，这个你可以上网搜搜，答案很多的
iBatis3里貌似确实木有批量插入，很郁闷的说

可以通过ibatis建立一对多的映射
