项目介绍

在线考试系统是利用Java web技术开发设计的。数据库是基于Mysql设计的。学生可以在线考试，系统实现自动阅卷，管理员可以管理学生信息，试卷信息，题目信息等；本系统分前台和后台两部分，前台实现功能有：学生登录，在线考试，成绩查询，修改密码等；后台实现功能有：管理员登录，考生信息管理，考生成绩查询，试卷管理，题目管理等；

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；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

技术栈

1. 后端：spring+spring mvc+hibernate

2. 前端：JSP+Javascript+Bootstrap

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，配置tomcat，然后运行；
2. 将项目中hibernate.cfg.xml配置文件中的数据库配置改为自己的配置;
4. 运行项目，考生登录页面输入http://localhost:8080/ 登录
考生账号密码：JS20140701094708/123456

管理员登录页面地址：http://localhost:8080/login2.jsp

管理员账号密码：admin/123456
