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,>_<

我也不懂...csdn找到的一个struts2+hibernate的例子

cocoyoona | 园豆:20 (初学一级) | 2016-05-18 09:15

@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!

LazyCat90 | 园豆:70 (初学一级) | 2016-05-18 09:47

@花落无声1991: mysql呀

cocoyoona | 园豆:20 (初学一级) | 2016-05-18 09:48

你都会改...我看hibernate都看不懂

cocoyoona | 园豆:20 (初学一级) | 2016-05-18 09:49

@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~

LazyCat90 | 园豆:70 (初学一级) | 2016-05-18 09:50

@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

cocoyoona | 园豆:20 (初学一级) | 2016-05-18 09:51

@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。

LazyCat90 | 园豆:70 (初学一级) | 2016-05-18 09:55

@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。

LazyCat90 | 园豆:70 (初学一级) | 2016-05-18 10:02

@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?

cocoyoona | 园豆:20 (初学一级) | 2016-05-18 10:04

@花落无声1991: 你扣扣.我截图给你看这样子太慢啦宝宝

cocoyoona | 园豆:20 (初学一级) | 2016-05-18 10:05

@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

LazyCat90 | 园豆:70 (初学一级) | 2016-05-18 10:12

@花落无声1991: 还是不懂...我感觉就不理解这个东西了

cocoyoona | 园豆:20 (初学一级) | 2016-05-18 10:14

@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。

LazyCat90 | 园豆:70 (初学一级) | 2016-05-18 10:17

@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

cocoyoona | 园豆:20 (初学一级) | 2016-05-18 10:20

@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。

LazyCat90 | 园豆:70 (初学一级) | 2016-05-18 10:21

@花落无声1991: 728699398..为什么叫丘丘而不是扣扣呢?

cocoyoona | 园豆:20 (初学一级) | 2016-05-18 10:22

@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!

LazyCat90 | 园豆:70 (初学一级) | 2016-05-18 10:25

@花落无声1991: 不晓得呢

cocoyoona | 园豆:20 (初学一级) | 2016-05-18 10:25

@眉间剪水泛千愁: 发给你了!请接收!

LazyCat90 | 园豆:70 (初学一级) | 2016-05-18 10:40

@花落无声1991: 这就是你的丘丘邮箱哈?

cocoyoona | 园豆:20 (初学一级) | 2016-05-18 10:41

@眉间剪水泛千愁: 对

LazyCat90 | 园豆:70 (初学一级) | 2016-05-18 10:41

@花落无声1991: 那我+你呐

cocoyoona | 园豆:20 (初学一级) | 2016-05-18 10:42

@眉间剪水泛千愁: 恩,好的!

LazyCat90 | 园豆:70 (初学一级) | 2016-05-18 10:43

@花落无声1991: 发过去啦..

cocoyoona | 园豆:20 (初学一级) | 2016-05-18 10:43

@眉间剪水泛千愁: 锦袖?

LazyCat90 | 园豆:70 (初学一级) | 2016-05-18 10:45

@花落无声1991: 不好听么?

cocoyoona | 园豆:20 (初学一级) | 2016-05-18 10:45

@眉间剪水泛千愁: 没有只是确认一下名字
