项目介绍
本项目分为前后台，包含管理员、站点管理员、用户三种角色；
管理员角色包含以下功能： 管理员登录,管理员管理,车辆类型管理,租赁站点管理,站点管理员管理,自行车信息管理,校园新闻管理,自行车租用统计,友情链接留言系统公告管理等功能。
站点管理员角色包含以下功能： 站点管理员登录,个人资料密码管理,充值管理,租赁归还记录管理,自行车管理,充值记录查询等功能。 用户角色包含以下功能：用户首页,在线留言,用户注册登录,自行车展示,租用自行车,校园新闻查看,租赁记录管理,归还记录管理等功能。
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
JSP+CSS+JavaScript+Servlet+mysql
使用说明
- 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CommDAO.java配置文件中的第472行数据库配置改为自己的配置; 4. 运行项目，在浏览器中输入localhost:8080/xxx 登录
