基于javaweb的茶叶售卖商城系统(java+ssm+jsp+easyui+mysql)

运行环境

Java≥8、MySQL≥5.7、Tomcat≥8

开发工具

eclipse/idea/myeclipse/sts等均可配置运行

适用

课程设计，大作业，毕业设计，项目练习，学习演示等

功能说明

基于javaweb+jsp的茶叶售卖商城系统(java+SSM+JSP+EasyUi+mysql)

这是一个应用SSM框架的项目，前端页面整洁清晰。该系统有两个角色，一个是普通用户，另一个是管理员。

普通用户具有注册、登录、查看商品、添加购物车、添加商品收藏、下订单、商品评价、用户地址管理等等功能。

管理员具有登录、管理用户信息、管理商品信息、管理商品活动信息、管理订单信息、管理用户评论信息的等等功能。

应用技术：Jsp + SSM + EasyUi

运行环境：eclipse/IDEA + MySQL5.7 + Tomcat8.5 + JDK1.8

商品管理服务层：
