项目介绍

本项目为小程序商城系统前后台，前台为普通会员用户登录，后台为管理员登录；
程序功能：
1.小程序前台：用户注册登录、首页、轮播图、新品推荐、分类、购物车、我的订单。

2.网站后台：管理员登录、用户管理、商品类别管理、商品管理、订单管理、公告管理；

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.tomcat环境：Tomcat 7.x,8.x,9.x版本均可
4.硬件环境：windows 7/8/10 1G内存以上；或者 Mac OS；
5.数据库：MySql 5.7版本；

6.是否Maven项目: 否；

技术栈

1. 后端：spring+struts+hibernate

2. 前端：JSP+css+javascript+jquery

使用说明

后台运行：
1. 使用Navicat或者其它工具，在mysql中创建对应名称的数据库，并导入项目的sql文件；
2. 使用IDEA/Eclipse/MyEclipse导入项目，Eclipse/MyEclipse导入时，若为maven项目请选择maven;
若为maven项目，导入成功后请执行maven clean;maven install命令，然后运行；
3. 将项目中config/jdbc.properties配置文件中的数据库配置改为自己的配置;
4. 运行项目，在浏览器中输入http://localhost:8080/shop
管理员：admin/111111

前台小程序运行：
1.使用微信开发者工具导入项目；
2.导入成功后编译运行；
3.运行成功后登录账号；
