基于javaweb+springboot的在线点餐系统(java+Springboot+ssm+mysql+maven)
一、项目简述
功能：数据库采用mysq昨为数据存储，系统中涉及到的关 键表有，用户表、用户详情表、商品表、订单表、商品订 单关联表、评价表等等。本系统分为前端和后端，前端功 能有：登录注册、修改个人信息、修改收货地址、查看商 品、加购商品、结算商品，对订单进行评价、用户留言等 功能；后端功能有：登录、商品管理、用户管理、订单管 理、留言公告管理等功能。本系统中的购物车功能设计、io流读写图片存放本地、订单导出、“echarts插件实现订单信 息统计、后台批量操作、pagehelper实现分页等细节值得 学习。

二、项目运行
环境配置： Jdk1.8 + Tomcat8.5 + mysql + Eclispe (IntelliJ IDEA,Eclispe,MyEclispe,Sts 都支持)

项目技术： JSP +Springboot+ SpringMVC + MyBatis + html+ css + JavaScript + JQuery + Ajax + Layui+ maven等等。
