简介：Java领域优质创作者、Java项目、学习资料、技术互助
文末获取源码
项目介绍
本系统分为两个角色，一个是考生，一个是管理员，
考生功能如下：
登录、选择考试科目、选择考卷、在线考试、提交试卷、并且查询自己的考试成绩
管理员功能如下：
登录、添加试卷、并且添加试卷里的题目、编辑科目、还可以查询所有考生的成绩
由于本程序规模不大，可供课程设计，毕业设计学习演示之用
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：servlet
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，然后运行；
3. 将项目中db.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/ 登录
