基于java+springmvc+mybatis+vue+mysql的四六级在线考试系统

项目介绍

基本每个大学生在校期间都要经历英语四六级考试的过程，只有通过了四六级的考试才能够顺利的领取到毕业证书，但是传统的四六级考试比较落后，都是人工的方式在进行各种工作，这不仅浪费人力物力，而且在时效上也有很大的弊端，为此我们开了本基于网络的四六级在线考试系统。

对于本四六级在线考试系统的设计来说，系统开发主要是采用java语言技术，后端采用ssm框架，前端采用vue技术，在整个系统的设计中应用MySQL数据库来完成数据存储，具体根据四六级在线考试系统的现状来进行开发的，具体根据现实的需求来实现四六级在线考试系统网络化的管理，各类信息有序地进行存储，进入四六级在线考试系统页面之后，方可开始操作主控界面，主要功能包括管理员：首页、个人中心、用户管理、考试成绩管理、公告通知管理、考生通知管理、试题管理、试卷管理、考试管理，用户：首页、个人中心、考试成绩管理、公告通知管理、考生通知管理、考试管理等功能。

本论文主要讲述了四六级在线考试系统开发背景，该系统它主要是对需求分析和功能需求做了介绍，并且对系统做了详细的测试和总结。具体从业务流程、数据库设计和系统结构等多方面的问题。望能利用先进的计算机技术和网络技术来改变目前的四六级在线考试系统状况，提高管理效率。

开发环境

开发语言：Java
数据库 ：MySQL
