SprinBoot+Vue在线考试系统的设计与实现(源码+数据库+文档)

项目描述
随着社会的发展，系统的管理形势越来越严峻。越来越多的用户利用互联网获得信息，但各种信息鱼龙混杂，信息真假难以辨别。为了方便用户更好的获得在线考试信息，因此，设计一种安全高效的在线考试系统极为重要。
为设计一个安全便捷，并且使用户更好获取在线考试信息，本文主要有安全、简洁为理念，实现用户快捷寻找在线考试信息，从而解决在线考试信息管理复杂难辨的问题。该系统采用java语言、Spring Boot框架和mysql数据库进行开发设计，通过对在线考试管理业务流程的分析，分析了其功能性需求，设计了在线考试系统，该系统包括管理员和教师、学生三部分。同时还能为用户提供一个方便实用的在线考试系统，使得用户能够及时地找到合适自己的在线考试系统。管理员界面管理教师、学生的信息，也可以对系统上的所有信息进行修删查等操作，用户通过本系统可以及时了解在线考试信息。
