功能说明
基于javaweb的SpringBoot社区团购系统(java+springboot+mybaits+vue+elementui+mysql)
项目介绍
基于Springboot+vue的社区团购系统设计
本系统分为前后台，包含管理员、用户两种角色，前台为普通用户登录，后台为管理员、用户分别登录。
前台主要功能：首页、商品信息、团购信息、社区信息、用户登录、用户注册、用户个人中心、我的订单、我的地址、我的收藏、购物车等功能；
后台管理员主要功能：首页、个人中心、用户管理、商品信息管理、商品类型管理、团购信息管理、系统管理等。
环境需要
1.运行环境：最好是java jdk 1.8，我们在这个平台上运行的。其他版本理论上也可以。
2.IDE环境：IDEA，Eclipse,Myeclipse都可以。推荐IDEA;
3.硬件环境：windows 7/8/10 1G内存以上；或者 Mac OS；
4.数据库：MySql 5.7/8.0版本均可；
5.是否Maven项目：是；
技术栈
后端：SpringBoot+Mybaits
前端：Vue+elementui
使用说明
项目运行：
使用Navicat或者其它工具，在mysql中创建对应sql文件名称的数据库，并导入项目的sql文件；
使用IDEA/Eclipse/MyEclipse导入项目，导入成功后请执行maven clean;maven install命令；
将项目中application.yml配置文件中的数据库配置改为自己的配置;
运行项目，在浏览器中输入地址：
前台地址：http://localhost:8080/springboot2c1hu/front/index.html
后台地址
http://localhost:8080/springboot2c1hu/admin/dist/index.html
管理员： abo 密码： abo
用户：用户1 密码： 123456
注意项目文件路径中不能含有中文、空格、特殊字符等，否则图片会上传不成功。
