我一直想知道hibernate是什么思想呢，据说是一个表对应一个数据库。。。
呵呵，支持下楼主先

我发现的问题：
1 目前没看到你JSF的影子。
2 hibernate的事务没提交。

#9

无理取闹2007-01-16 12:10

jsf 我定义了userBean
hibernate哪里没提交？？

#10

无理取闹2007-01-16 12:37

哦对了我的全部源码在一楼有兴趣可以下载看看

#11

支离破碎2007-01-16 13:18

建议加入SPRING框架~~~~(最近也学了学JSF。。和原来我用过的Tapestry感觉差不多的。基于组件的。。）

#12

无理取闹2007-01-16 13:35

我刚刚才开始学习框架的东西
所以想把spring留到掌握hibernate后来学习
谢谢楼上建议

private Transaction tx=session.beginTransaction();
public List<LUser> getByName(String username) {
String sql="from LUser user where username=:name";
Query query=session.createQuery(sql);
query.setParameter("name", username);
return query.list();

是不是缺少了个commit() ?

#14

无理取闹2007-01-16 16:11

这个方法不需要commit();
如果有空你可以仔细看看我的代码
谢谢

#15

private Transaction tx=session.beginTransaction();
public List<LUser> getByName(String username) {
String sql="from LUser user where username=:name";
try{
Query query=session.createQuery(sql);
query.setParameter("name", username);
return query.list();
tx.commit();
}catch(HibernateException e)
{
e.printStackTrace();
rollback();
}
