仿牛客社区——2.3.3账号设置（修改密码）

实现功能

当用户在账号设置页面修改密码时，输入完原始密码以及新密码、确认密码后，当点击【立即保存】后，若用户原始密码输入正确，新密码与确认密码一致时，会跳转至登录页面重新登录，若输入有误，则显示对应的错误信息

controller层

//修改密码
    @RequestMapping(value = "/updatePassword",method = RequestMethod.POST)//@CookieValue("ticket") String ticket：从浏览器器中得到cookie
    public String updatePassword(String oldPassword, String newPassword, String confirmNewPassword, Model model,@CookieValue("ticket") String ticket){
        //对传入参数进行判断，不能为空
        if(StringUtils.isBlank(oldPassword)){
            model.addAttribute("oldPasswordMsg","请输入原始密码！");
            return "site/setting";
        }
        if(StringUtils.isBlank(newPassword)){
            model.addAttribute("newPasswordMsg","请输入新密码！");
            return "site/setting";
        }
        if(StringUtils.isBlank(confirmNewPassword)){
            model.addAttribute("confirmNewPasswordMsg","请输入确认密码！");
            return "site/setting";
        }
        //首先通过所持有的的用户对象获取当前用户
        User user = hostHolder.getUser();
        //判断用户输入的原密码是否与存储的原密码一致
        //首先对用户输入的原密码进行加密处理
         oldPassword = CommunityUtil.md5(oldPassword+user.getSalt());
         if(!oldPassword.equals(user.getPassword())){
             model.addAttribute("oldPasswordMsg","该密码与原密码不符!");
             return "site/setting";
         }
         //判断新输入密码与原密码是否一致
        //对新密码进行加密
        newPassword=CommunityUtil.md5(newPassword+user.getSalt());
        if(newPassword.equals(user.getPassword())){//判断
            model.addAttribute("newPasswordMsg","新密码与原密码一致!");
            return "site/setting";
        }
        //对确认密码进行加密
        confirmNewPassword=CommunityUtil.md5(confirmNewPassword+user.getSalt());
        if(!newPassword.equals(confirmNewPassword)){//判断
            model.addAttribute("confirmNewPasswordMsg","两次密码不一致!");
            return "site/setting";
        }
        userService.updatePassword(user.getId(),newPassword);
        //修改密码后，用户需要重新登陆，所以在本次持有中释放用户
        userService.logout(ticket);
        return "redirect:/login";
    }

 service层

通过当前的用户id，和传入的密码，修改用户的密码

//修改密码
    public int updatePassword(int userId,String password){
        return userMapper.updatePassword(userId,password);
    }
