Java项目:在线嘿嘿网盘系统设计和实现(java+Springboot+ssm+mysql+maven)
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，支持通过链博口二维码的分享方式等等。
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
