03-Springboot电脑网上商城项目-修改密码和个人资料

四、修改密码

需要用户提交旧密码和新密码,再根据当前用户信息进行修改

1 修改密码-持久层

1.规划需要执行的sql语句

根据uid修改用户数据,修改者和修改时间也要更改

update t_user set password = #{password},modified_user = #{modifiedUser},modified_time = #{modifiedTime} where uid = #{uid}

根据uid查询用户信息,检测是否被删除原始密码是否正确

select * from t_user where uid = #{uid}

2.设计接口和抽象方法

UserMapper接口

/**
     * 根据uid修改用户数据
     * @param uid
     * @param password 新密码
     * @param modifiedUser
     * @param modifiedTime
     * @return 受影响的行数,便于判断是否更新成功
     */
    Integer updatePasswordByUid(Integer uid, String password, String modifiedUser, Date modifiedTime);

    /**
     * 根据uid查询用户信息
     * @param uid
     * @return 用户存在返回用户信息,否则返回null
     */
    User finUserByUid(Integer uid);

UserMapper.xml

 <update id="updatePasswordByUid">
        update t_user set
            password = #{
   password},
            modified_user = #{
   modifiedUser},
            modified_time = #{
   modifiedTime}
        where uid = #{
   uid}
    </update>
    
    <select id="finUserByUid" resultMap="UserEntityMap">
        select * from t_user where uid = #{
   uid}
    </select>
  1. 测试

     @Test
        public void updatePassword(){
         
            Integer i = userMapper.updatePasswordByUid(6,"123","zhou",new Date());
            System.out.println(i);
        }
    
        @Test
        public void finUid(){
         
            System.out.println(userMapper.finUserByUid(06));
        }
    

2 修改密码-业务层

  1. 规划肯能出现的异常:用户密码错误、用户被删除、更新密码时异常(updatePasswordException)

  2. 设计接口和抽象方法

    void changePassword(Integer uid,String username,String oldPassword,String newPassword);
    
    @Override
        public void changePassword(Integer uid, String username, String oldPassword, String newPassword) {
         
            User user = userMapper.finUserByUid(uid);
            //判断用户是否存在或被删除
            if (user == null || user.getIsDelete() == 1){
         
                throw new UsernameNotFoundException("用户数据不存在");
            }
    
            String oldMd5Password = getMD5Password(oldPassword, user.getSalt());
            //判断老密码是否正确
            if (!oldMd5Password.equals(user.getPassword())){
         
                throw new PasswordNotMatchException("密码错误");
            }
            String newMd5Password = getMD5Password(newPassword, user.getSalt());
            //更改新密码
;
