Web项目中使用了Strut2和Hibernate，往数据库里写入条目有问题

[杉彤守护神]

服务器: TOMCAT 7; 开发软件：Eclipse；使用了HibernateUtil类

代码如下：

if(user.getUsername().equals("ad")&&user.getPassword().equals("ad")){
UserDAO userdao = DAOFactory.getUserDAOInstance();
try{
User u = new User();
u.setId(5);
u.setUsername(user.getUsername());
u.setPassword(user.getPassword());
userdao.save(u);
this.success= true;
}catch(Exception e){
e.printStackTrace();
this.success=false;
this.message="对不起，未授权的用户不能登录改系统";
}
//this.message="你的账号是："+user.getUsername()+"密码是："+user.getPassword();
}else{
this.success=false;
this.message="对不起，未授权的用户不能登录改系统";
}
return SUCCESS;

这个代码去掉返回成功、失败之后，其他在Junit中执行正常，可以写入数据库，但在Strut2的Action里总是出错，调试时发现在Save（u）程序段报错，但为什么Juint执行正常呢，新手求解，还请帮忙。

报的啥子错误哦

不好意思，没有看到错误报出啊。。。，我的其他两个文件源码： DAOFactory.java

调试时每次到UserDAOImpl.java文件的第12行 Session session= HibernateUtil.getSession(); //生成Session实例 报错 InvocationTargetException.<init>(Throwable)line:not availabe source not found 不知道什么原因，还请版主帮忙，折腾了一个星期了。

[杉彤守护神]

还请版主和各位高人帮忙，Action程序就是不执行数据库的save(u)操作，但是使用Juint就完全没有问题，这到底是咋回事啊，strut2 Action有什么特别的啊？！

引用 9 楼 kevinlifeng 的回复:

static { try { Configuration cfg=new Configuration().configure(); //读取配置文件hibernate.cfg.xml sessionFactory=cfg.buildSessionFactory(); //创建SessionFactory } catch (Throwable ex) { throw new ExceptionInInitializerError(ex); } } 是不是你的configure("/hibernate.cfg.xml")没有添加参数呀！！

谢谢，经测试不是这个问题，看报警好像是线程的问题，到为什么Juint工作正常呢，放在Struts2的Action中为什么就会有问题，还请各位大侠帮忙。

[杉彤守护神]

谢谢大侠提醒，我加入进去之后还是没有提示，这到底怎么回事啊？ 大侠给看看是不是操作数据库方面有问题呢，为什么同样的代码在Juint里就可以运行正常呢?

[kevinlifeng]

是不是，你的static初始块中

static {         try {             Configuration cfg=new Configuration().configure();        //读取配置文件hibernate.cfg.xml             sessionFactory=cfg.buildSessionFactory();                //创建SessionFactory         } catch (Throwable ex) {             throw new ExceptionInInitializerError(ex);         }     } 

，configure("/hibernate.cfg.xml")呀！你可以试试

[kevinlifeng]

static { try { Configuration cfg=new Configuration().configure(); //读取配置文件hibernate.cfg.xml sessionFactory=cfg.buildSessionFactory(); //创建SessionFactory } catch (Throwable ex) { throw new ExceptionInInitializerError(ex); } } 是不是你的configure("/hibernate.cfg.xml")没有添加参数呀！！
