在Internet高速发展的今天，我们生活的各个领域都涉及到计算机的应用，其中包括学习平台的网络应用，在外国学习平台已经是很普遍的方式，不过国内的管理平台可能还处于起步阶段。学习平台具有学习信息管理功能的选择。学习平台采用java技术，基于springboot框架，mysql数据库进行开发，实现了首页，个人中心，学生管理，教师管理，课程信息管理，类型管理，作业信息管理，资料信息管理，签到信息管理，成绩统计管理，学生作业管理，试卷管理，试题管理，校园论坛，系统管理等内容进行管理，本系统具有良好的兼容性和适应性，为用户提供更多的学习信息，也提供了良好的平台，从而提高系统的核心竞争力。
本文首先介绍了设计的背景与研究目的，其次介绍系统相关技术，重点叙述了系统功能分析以及详细设计，最后总结了系统的开发心得。

Abstract
With the rapid development of Internet today, every field of our life involves the application of computers, including the network application of learning platform. Learning platform has been a very common way in foreign countries, but the domestic management platform may still be in its infancy. The learning platform has the choice of learning information management functions. Learning platform USES Java technology, based on springboot framework, mysql database development, realize the home page, personal center, student management, teacher management, curriculum information management, type management, information management, information management, sign in information management, performance statistics management, student management, test management and test question management, Campus forum, system management and other content management, the system has good compatibility and adaptability, to provide users with more learning information, but also provides a good platform, so as to improve the core competitiveness of the system.
This paper first introduces the design background and research purpose, then introduces the system related technology, focuses on the system function analysis and detailed design, and finally summarizes the development experience of the system.
