喝不起奶茶，咱就为奶茶店开发个会员积分收银系统

作者主页：编程指南针

 简介：Java领域优质创作者、博客专家  Java项目、简历模板、学习资料、面试题库、技术互助

文末获取源码

 项目编号：BS-XX-011

本系统基于SSM框架开发实现，前端使用easyui开发实现，功能强大，界面美观，数据库使用mysql数据库，开发工具采用idea。

系统部分功能展示如下：

系统管理员登陆： admin /admin

http://localhost/login

登陆后主界面：

用户管理

角色管理

资源管理

地区管理

奶茶管理==类目管理

点击购买==输入会员卡进行购买

消费积分管理

日志管理

以上是奶茶店会员管理系统的部分功能展示，本项目功能完整，运行无误，适合做毕业设计使用。
