管理员账号/密码：admin/123456
用户账号/密码： userloop/123456

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.是否Maven项目: 否；查看源码目录中是否包含pom.xml；若包含，则为maven项目，否则为非maven项目 
6.数据库：MySql 5.7版本；

技术栈

1. 后端：Spring SpringMVC MyBatis
2. 前端：JSP+bootstrap+jQuery

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，下载所需要的jar包；
3. 将项目中beans.xml配置文件中的数据库配置改为自己的配置,主要用户名、密码；
4. 配置tomcat，然后运行运行项目，输入http://localhost:8080/ 登录
