项目介绍

本项目为前后台管理系统，包括管理员与普通用户两种角色；
管理员角色包含以下功能：
管理员登录,用户管理,商品类型管理,商品管理,订单信息管理,用户留言管理,资讯管理等功能。

用户角色包含以下功能：
用户首页,用户登录,商品推荐,资讯信息,留言板,查看商品,提交订单,查看订单信息,个人资料管理等功能。

ps:推荐模块用了协同过滤推荐算法，下订单模块用的是百度地图api。本商城可以修改为任意商城不止是体育商城。

使用说明

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application.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:8110/ 登录
