项目介绍
这个项目是一个基于SSM的在线考试系统，分为考试用户和管理员两种角色。
考试用户功能包括：
个人信息中心
成绩查询
在线答题
我的错题本
我的试卷
管理员功能包括：
试题管理
题型管理
用户管理
年级管理
课程管理
试卷管理
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：是；
技术栈
1. 后端：Spring+SpringMVC+Mybatis
2. 前端：JSP+css+javascript+jQuery+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，然后运行；
3. 将项目中jdbc.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:8080/online_exam_ssm/toLogin.action 登录
学生账户：zhangsan/123456
后管登录地址：http://localhost:8080/online_exam_ssm/admin/login.action
管理员账户：admin/123456
