说是没有找到数据源，是不是你的Hibernate配置错误了
还有就是，你这是用的什么数据库啊？
没有见过这个驱动，>_<
奖励园豆：5
我也不懂...csdn找到的一个struts2+hibernate的例子
@眉间剪水泛千愁: 你现在用的是什么数据库？oracle？sql server？DB2？mysql？你告诉我你用的数据库，我才能帮你改一下！
O(∩_∩)O~
他上面这个数据库好像是一个很小型的数据库，不常见。我是没有见过！
@花落无声1991: mysql呀
你都会改...我看hibernate都看不懂
@眉间剪水泛千愁: 我最近才学的SSH（Struts2 + Spring + Hibernate）框架，这方面还是知道些许的！O(∩_∩)O~
@花落无声1991: 我刚学会点struts2,hibernate我真是不懂,现在映射差不多应该知道点了,但是用hibernate不是就不需要jdbc了么?不需要jdbc然后就茫然了Dao里就不知道怎么写
@眉间剪水泛千愁: hibernate是管理实体类与数据库的映射的（orm框架，object-relation-mapping），dao里面访问数据库可以直接调用hibernate的方法，或者是使用方法直接执行Hql & sql 语句进行数据库交互。
@眉间剪水泛千愁: 
DriverClass直接照抄下来，jdbc根据那个格式写一下数据库地址。
@花落无声1991: 也就是说使用hibernate之后,就不需要在写jdbc了,然后直接映射实体类呗.但是这样不写jdbc的话,Dao里面怎么写呢?
@花落无声1991: 你扣扣.我截图给你看这样子太慢啦宝宝
@眉间剪水泛千愁: 我们上班不让用丘丘，代理屏蔽了丘丘，嘿嘿。
Dao里面就是这样简单的实现了按照id来获得User实例化对象的，
里面的getObject()方法是继承的HibernateDAO里面的方法，应该是这样的，因为我使用的SSH框架和这个还有点不同，我那里是这样的
@花落无声1991: 还是不懂...我感觉就不理解这个东西了
@眉间剪水泛千愁:
也可以是这样，
这个是我使用Spring管理SessionFactory之后，你看那个应该是早起的Hibernate里面的方法吧！我看的是最新的学习资料。
上面这个例子里面是直接使用的HQL（Hibernate自己的查询语言）来进行查询User类。
@花落无声1991: hibernate它自己不需要spring么?就是说如果我只用struts2+hibernate做,然后映射完成后需要写Dao,听他们说写dao还需要hibernate的工具类,但是hibernate的工具类又需要spring
@眉间剪水泛千愁: 你还是看看这方面的资料吧！要不然看代码会什么都不懂！我也是自学了两三个月了，才到这点程度，我给你一个系统，也是在CSDN上下载的，我现在感觉那个系统写的很全面。你的丘丘是多少？我直接发邮件给你。
@花落无声1991: 728699398..为什么叫丘丘而不是扣扣呢?
@眉间剪水泛千愁: 小孩子小的时候说话说不清楚，就说丘丘，我外甥经常这样说，咕~~(╯﹏╰)
网上面也有很多人这样说啊！你不知道！
@花落无声1991: 不晓得呢
@眉间剪水泛千愁: 发给你了！请接收！
@花落无声1991: 这就是你的丘丘邮箱哈?
@眉间剪水泛千愁: 对
@花落无声1991: 那我+你呐
@眉间剪水泛千愁: 恩，好的！
@花落无声1991: 发过去啦..
@眉间剪水泛千愁: 锦袖？
@花落无声1991: 不好听么?
@眉间剪水泛千愁: 没有只是确认一下名字
