设计自主学习系统介绍
设计自主学习系统是一个基于Spring Boot后端框架和Vue前端技术构建的综合性在线学习平台，采用B/S架构模式，使用MySQL数据库进行数据存储和管理。该系统主要面向教育机构的师生群体，通过整合多种学习功能模块，为用户提供完整的在线学习解决方案。系统核心功能涵盖用户管理、学习资料管理、在线考试管理、学习论坛交流等多个方面，学生可以通过系统浏览和下载各类学习资料，参与在线考试测评，在论坛中进行学术讨论和经验分享，教师则可以发布学习内容，管理试题库，组织在线考试，并通过系统跟踪学生的学习进度和考试成绩。系统采用ElementUI组件库构建用户界面，确保良好的用户体验和操作便捷性，同时利用Spring Boot的微服务特性和MyBatis的数据持久化能力，保证系统的稳定性和扩展性，为现代化教育信息化建设提供了实用的技术支撑。
