系统说明

《javaweb网络考试系统的设计与实现》该项目采用技术jsp、servlet、jdbc、beanutils、dbutils、tomcat服务器、mysql数据库，前端用了bootstrap和jquery框架开发工具eclipse，项目含有源码、论文、配套开发软件、软件安装教程、项目发布教程

项目功能介绍：网络考试系统主要用于实现高校在线考试，基本功能包括：自动组卷、试卷发布、试卷批阅、试卷成绩统计等。

本系统结构如下：

（1）学生端：

登录模块：登录功能；

网络考试模块：可参加考试，并查看考试结果，提交试卷后老师允许的情况下查看错题；

（2）超级管理员端：

登录模块：实现管理员登录功能；

用户管理模块：实现用户信息的增加、修改、查看功能；

角色权限管理模块：实现角色的增加、修改、查看功能；

试卷管理模块：实现试卷信息的增加、修改、查看功能；

试题管理模块：实现试题信息的增加、修改、查看功能；

（3）试题管理员端（老师）：

试卷管理模块：实现试卷信息的增加、修改、查看功能；

试题管理模块：实现试题信息的增加、修改、查看功能；

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

1. 后端：Spring+SpringMVC+Mybatis

2. 前端：JSP+CSS+JavaScript+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，然后运行；

3. 将项目中springmvc-servlet.xml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/ 登录
