我是靠谱客的博主故意黑夜，这篇文章主要介绍自己动手用Springboot实现仿百度网盘的实践，现在分享给大家，希望可以做个参考。

项目编号：BS-PT-032

本项目基于Springboot开发实现，前端采用BootStrap开发实现，系统功能完整，交互性好，模仿百度网盘实现相关功能，比较适合做毕业设计使用，创意性强。

开发工具为IDEA或ECLIPSE，数据库采用MYSQL数据库。

系统部分功能展示如下：

http://localhost:8080/toLogin admin / 123456

登陆页面：

主页

对应本地磁盘存储目录：

分享网盘资料

根据提取码下载相关资料

下载

重命名文件或文件夹

文件上传

新建文件夹

上传音乐文件后可以一键自动播放

以上是本系统的部分展示功能，可以做为毕业设计使用。

部分代码实现如下：

复制代码
