ssm+mysql实现在线点餐系统
项目描述：这是一个基于SpringBoot+Vue框架开发的在线点餐系统。首先，这是一个前后端分离的项目，代码简洁规范，注释说明详细，易于理解和学习。其次，这项目功能丰富，具有一个在线点餐系统该有的所有功能。
项目功能：此项目分为两个角色：普通用户和管理员。普通用户有登录注册、浏览商品信息、添加购物车、结算订单、查看个人信息、查看个人订单详情等等功能。管理员有管理所有商品信息、管理所有订单信息、管理所有用户信息、查看收益数据图表等等功能。
应用技术：SpringBoot + VueCli + MySQL + MyBatis + Redis + ElementUI
运行环境：IntelliJ IDEA2019.3.5 + MySQL5.7（项目压缩包中自带) + Redis5.0.5（项目压缩包中自带） + JDK1.8 + Maven3.6.3（项目压缩包中自带）+ Node14.16.1（项目压缩包中自带）
