Java毕业设计实战之在线网盘系统的实现

作者:OldWinePot

这是一个使用了java+JSP+Springboot+maven+mysql+ThymeLeaf+FTP开发的在线网盘系统,是一个毕业设计的实战练习,具有网盘该有的所有功能,感兴趣的朋友快来看看吧

一、项目简述

功能:用户的邮箱注册、验证码验证以及用户登录。 不需要注册账号,也可以上传满足条件的临时文件,但是只4小时内有效。 文件的管理,上传、下载、重命名、删除、查看统计数据、分类管理等。 文件夹的管理,创建、删除、重命名。 文件的分享,支持通过链接和二维码的分享方式等等,以及管理员对用户的管理等等。

二、项目运行

环境配置:

Jdk1.8 + Tomcat8.5 + mysql + Eclispe(IntelliJ IDEA,Eclispe,MyEclispe,Sts都支持)

项目技术:

JSP +Springboot+ SpringMVC + MyBatis + ThymeLeaf + FTP+ JavaScript + JQuery + Ajax + maven等等

文件仓库控制器:

@Controller
public class FileStoreController extends BaseController {
