以上错误！ 是我在搭建string+truts+ibatis框架的时候用spring链接oracle数据库的时候报的错误！ 在网上找了很多的资料。

总结一下2点来解决这个错误！  

总体来看：invalid username/password  

字面意思是：无效的用户名/密码。那么可以从一下2点来看：

首先最重要的一点你要确定你的账号密码可以登录plsql。

1：用系统用户登录plsql , 查询当前的所有用户： select * from dba_users;   查看状态是否被锁(LOCKED ),如果你数据库连接的用户被锁，

.给帐号解锁
alter user user1 account unlock;   有很多是用户被锁了导致的。

2.我是更换了一个用户才解决这个问题的。重新create一个用户，把报错的用户的所有权限转到新的用户上面，这个就解决问题啦。

3.还有就是一个登陆 sysdba和Normal的问题，有很多的时候就是这个问题困扰了开发者。解决办法

A.put("user"，admin)；//用户

　　A.put("password"，admin)； //密码

　　 有些连接时这样的代码，如果是oralce数据库的话，报上面你的错。你可以试着把下面的代码加上！

　　A.put("internal_logon"，"sysdba")；

希望能帮到你们！
