Goods:修改密码功能及退出功能实现

//修改密码
public String updatePassword(HttpServletRequest req, HttpServletResponse resp)
{
/*
* 1、封装表单数据到userzhong
* 2\从session中获取uuid
* 3、使用uid 和表单中的oldPass和newpass来调用serviceff
*   如果出现异常 保存异常信息到request中 转发到pwd.jsp
*  4、保存成功信息到request中
*  5、转发到msg.jsp
*/

User formUser = CommonUtils.toBean(req.getParameterMap(), User.class);
User user=(User) req.getSession().getAttribute("sessionUser");
if(user==null)
{
req.setAttribute("msg", "您还没有登录");
return "f:/jsps/user/login.jsp";
}

try {
userService.updatePassword(user.getUid(), formUser.getNewpass(),

//没有抛出异常保存成功信息
req.setAttribute("msg", "修改密码成功");
req.setAttribute("code", "success");

} catch (UserException e) {

// 修改密码

// 退出功能
public String quit(HttpServletRequest req, HttpServletResponse resp) {
