牛客社区项目之修改密码

从下都上
UserMapper
//更新密码
int updatePassword(int id,String password);


user-mapper.xml
<update id="updatePassword">
    update user set password = #{password} where id = #{id}
</update>


UserService
//个人设置修改密码功能
public Map<String,Object> updatePassword(String password,String newPassword,int id){
    Map<String,Object> map =new HashMap<>();
    User user = userMapper.selectByID(id);
    password= CommunityUtil.md5(password+user.getSalt());
    if(!user.getPassword().equals(password)){
        map.put("passwordMsg","输入密码错误！");
        return map;
    }
    else {//注意：存入新密码要以加密后的形式存进去
        newPassword= CommunityUtil.md5(newPassword+user.getSalt());
        userMapper.updatePassword(id,newPassword);
    }

    return map;
}


UserController
//个人设置页面修改密码功能
//这里形参用Model类和User类即可，SpringMVC会把传入内容按照User属性填入user
@RequestMapping(path = "/setting", method = RequestMethod.POST)
public String updatePassword(Model model, String password,String newPassword,String confirmPassword) {
   if(StringUtils.isBlank(password)){
       model.addAttribute("passwordMsg","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(confirmPassword)){
        model.addAttribute("confirmPasswordMsg","请再次输入新密码！");
        return "/site/setting";
    }
    if(!confirmPassword.equals(newPassword)){
        model.addAttribute("newPasswordMsg","两次输入的新密码不相同！");
        return "/site/setting";
    }
    User user=hostHolder.getUser();
    Map<String, Object> map = userService.updatePassword(password,newPassword,user.getId());
    if (map == null || map.isEmpty()) {
        //传给templates注册成功信息
        model.addAttribute("msg", "密码修改成功");
        //跳到回个人设置页面
        model.addAttribute("target", "/user/setting");
        return "/site/operate-result";
    }else {
        //失败了传失败信息，跳到到原来的页面
        model.addAttribute("passwordMsg","输入的原始密码错误！");
        return "/site/setting";
    }


}
