[Java知识库]IDEA+Java+SSH+Bootstrap+Mysql实现在线考试系统(含论文)

?

一、系统介绍

1.开发环境

开发工具：IDEA2018.2

JDK版本：jdk1.8

Mysql版本：8.0.13

2.技术选型

1.后端：使用Java+SSH进行开发，使用过滤器来验证用户是否登录，使用MVC进行分层。

2.数据库：使用Hibernate作为数据持久化框架。

3.前端：使用Bootstrap作为前端框架来开发，使用到jstl来遍历数据。jsp来展示页面。

3.系统功能

1.学生

1.在线开始

2.成绩查询

3.修改密码

2.管理员

1.学生信息管理

考生信息的增删改查

2.考试成绩查询

3.试卷信息管理

试卷的增删改查

4.试题信息管理

试题信息的增删改查

4.数据库
