基于SpringBoot的在线网络学习平台介绍
基于SpringBoot的在线网络学习平台是一个功能完善的现代化教育管理系统,采用当前主流的B/S架构设计,支持Java+SpringBoot和Python+Django双技术栈实现方案。该系统以Vue+ElementUI构建前端界面,结合MySQL数据库进行数据存储,为用户提供完整的在线学习体验。平台核心功能涵盖学生信息管理、教师信息管理、课程视频播放、课程类型分类、课程资料下载等基础教学模块,同时支持付费报名和免费课程两种学习模式,满足不同用户需求。系统设计了完整的课程管理体系,包括课程公告发布、学习排行榜展示、积分礼品兑换等激励机制,有效提升用户学习积极性。在教学互动方面,平台提供课程作业发布、作业提交、作业批改的完整流程,同时建立了论坛讨论功能和论坛分类管理,支持学习者之间的交流互动。系统还具备举报记录处理、轮播图管理、公告信息发布等管理功能,确保平台运营的规范性和安全性。通过个人中心功能,用户可以管理个人信息、查看学习进度、兑换积分等。整个系统结构清晰、功能模块化,既适合作为毕业设计项目展示技术能力,也具备实际部署运行的商业价值,是计算机专业学生掌握全栈开发技术的理想实践项目。
