项目介绍

本项目是在线模拟考试系统的设计与实现，系统采用浏览器/服务器模式开发，包括登录注册、在线考试、试卷设置、试题管理、分数的统计以及成绩查询等功能。系统运行在Windows操作系统上，以Tomcat作为Web服务器,使用SSH+JSP技术和MySQL数据库实现。

项目主要包含管理员、教师与学生三种角色；

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+structs+hibernate

2. 前端：JSP+Javascript+css

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，浏览器中输入http://localhost:8080/ctest 登录
