感兴趣的可以先收藏起来，还有大家在毕设选题，项目以及论文编写等相关问题都可以给我留言咨询，希望帮助更多的人

一、采用技术：

后端：Java+SpringBoot

前端：Vue

数据库：MySQL

开发软件：Eclipse、MyEclipse、IDEA都可以运行

二、系统功能：

本信息化在线教学平台有管理员功能有个人中心，学生信息管理，教师信息管理，教学信息管理，学生成绩管理，留言板管理，系统管理等。教师可以对学生成绩进行管理和留言回复。学生可以在线考试和留言。因而具有一定的实用性。

本站是一个B/S模式系统，采用Spring Boot框架，MySQL数据库设计开发，充分保证系统的稳定性。系统具有界面清晰、操作简单，功能齐全的特点，使得信息化在线教学平台管理工作系统化、规范化。本系统的使用使管理人员从繁重的工作中解脱出来，实现无纸化办公，能够有效的提高信息化在线教学平台管理效率。
