求助！Struts2与Hibernate问题，急、急、急！!!
现在有两个实体类关系是一对多，User类为一，Question类为多。
User类使用Set持有Q类的引用private Set<Question> question;
Q类使用User类的引用private User user；

用户登录后，在提交问题表单中，增加问题的各个属性，Question表的外键关联User类的主键。

最后要根据用户查看用户所提问的问题。
如何编写，求高手赐教 可以根据数据库用myeclipse工具生成xxxx.hbm.xml文件,然后根据自己的需求在修改相关参数，可能需要你自己好好研究一下，这个一句两句真讲不清楚的，给你一个例子，你好好看看，这个是我自己的项目：
