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 POJO Java code
