我在看完Hibernate第一课视频后，就自已动手做了一个数据添加的小项目。可是问题也随之出现了，我使用的是oracle数据库。
表设计完了，对应表中的自增长字段我也随之写出了序列与触发器，可是执行的时候却发生了问题。在映射的xml中主键生成器是sequence 我已经查过了
下面是错误的提示
HTTP Status 500 - type Exception report
message

note The full stack trace of the root cause is available in the Apache Tomcat/5.5.12 logs.
Apache Tomcat/5.5.12
插入的源代码如下
Session session=HibernateSessionFactory.getSession();
Reguser reguser=new Reguser();
reguser.setName(registeruserform.getName());
reguser.setPassword(registeruserform.getPassword());
reguser.setMoney(new Double(500.00));
reguser.setRolename(new String("common"));
session.save(reguser);
session.beginTransaction().commit();
session.clear();
下面是后台输入的记录
Hibernate: select hibernate_sequence.nextval from dual
跪求各位高手给予小弟指点 |
