一，功能介绍
本点单系统主要是基于SpringBoot框架和小程序开发的，主要是为当代人们的生活提供更便利、更高效的服务，也为营销者提供更好的系统进行用户、商品、订单等信息管理。
该系统所实现的主要功能模块如下：
前台：
1）注册登录
2）个人中心
① 修改个人信息
② 修改收货地址
③ 积分
3）商品浏览
4）商品搜索
5）购物车
6）下单支付后台：
1）注册登录
2）个人中心
① 修改个人信息
② 修改密码
3）用户管理
① 客户信息管理
② 管理员信息管理
4）商品管理
① 商品分类管理
② 商品信息管理
③ 库存与销量
5）订单管理
前台提供用户注册登录、个人中心、浏览商品、查找商品、添加商品入购物车、订单提交以及支付等功能。后台提供管理注册登录、修改密码、修改个人信息、用户信息管理、管理员信息管理、商品信息管理、商品分配管理、库存与销量统计、订单管理等功能。
二，开发语言介绍
采用的SpringBoot+Vue+微信小程序进行开发，数据库采用的是Mysql。
