今天给大家演示的是一款由jsp+ssm框架（spring+springMVC+mybatis）+mysql实现的在线考试系统源码和开发教程，本系统配有完整的源码、视频开发教程、数据库文件、项目素材等详细材料。这里强调一点，本系统是在我们的万能脚手架系统的基础上开发的，如果你还没有学习脚手架系统开发教程的话请先去学习脚手架系统，如果你不学习脚手架系统的话这个系统你学不会哦！当然如果你只想要本系统的代码，并不想学习开发教程的话那你直接获取本项目资料就可以了，或者你基础能力很牛逼，那你也可以直接学习这个。本系统除了脚手架的基本功能外，实现的关于在线考试的功能有：用户前台：用户注册登录、查看考试信息、进行考试、查看考试成绩、查看历史考试记录、回顾已考试卷、修改密码、修改个人信息等，后台管理功能（脚手架功能不在这里列出），科目专业管理、考生管理、试题管理、考试管理、试卷管理、答题详情管理、考试成绩图表统计等，其中试题可以支持批量excel文件导入，试卷试题是随机生成的，每个人的试卷试题都不一样。
