本项目分为前后台，前台为普通用户登录，后台为管理员登录；

用户角色包含以下功能：

按分类查看场地,用户登录,查看网站公告,按分类查看器材,查看商品详情,加入购物车,提交订单,查看订单,修改个人信息等功能。

管理员角色包含以下功能：

管理员登录,管理员信息管理,用户信息管理,新闻公告信息管理,实体类型信息管理,场地信息管理,器材信息管理,评价信息管理等功能。

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；

1. 后端：Spring+SpringMVC+Mybatis

2. 前端：JSP+CSS+JavaScript+jQuery

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springmvc-servlet.xml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/ 登录
