UserService

1 // 修改密码 2     public void updatePassword(String uid, String newPass, String oldPass) 3             throws UserException { 4  5         try { 6             // 校验老密码 7             boolean bool = userDao.findByUidAndPassword(uid, oldPass); 8             if (!bool) { 9                 throw new UserException("老密码错误");10             }11             // 修改密码12             userDao.updatePassword(uid, newPass);13         } catch (SQLException e) {14             // TODO Auto-generated catch block15             throw new RuntimeException(e);16         }17 18     }

 退出功能实现:

1 // 退出功能2     public String quit(HttpServletRequest req, HttpServletResponse resp) {3         // session无效4         req.getSession().invalidate();5         return "r:/jsps/user/login.jsp";6 7     }
