這篇文章主要介紹“Java+Springboot怎么搭建在線網(wǎng)盤文件分享系統(tǒng)”，在日常操作中，相信很多人在Java+Springboot怎么搭建在線網(wǎng)盤文件分享系統(tǒng)問題上存在疑惑，小編查閱了各式資料，整理出簡單好用的操作方法，希望對大家解答”Java+Springboot怎么搭建在線網(wǎng)盤文件分享系統(tǒng)”的疑惑有所幫助！接下來，請跟著小編一起來學習吧！
springboot+freemark+jpa+MySQL實現(xiàn)的在線網(wǎng)盤文件分享系統(tǒng)，其功能跟百度網(wǎng)盤非常類似，普通用戶可以注冊登錄，注冊后默認分配1G的空間大小，登錄進去后可以新建文件夾、上傳各種類型的文件、文件移動、復制、下載、刪除、分享，分享分為私密分享和公開分享，還可以設置分享過期時間，打開分享鏈接后可以對文件進行查看、下載、保存到自己網(wǎng)盤等。超級管理員登錄后可以設置普通用戶的空間大小、角色類型、權限等。
本系統(tǒng)主要涉及的特色功能有：
1：系統(tǒng)在上傳文件時自動計算文件的md5值，并且檢查該值是否存在，若存在則文件不再上傳到服務器，直接進行引用原有的文件。
2：定時器定時檢查限時分享的文件是否過期。
3：網(wǎng)盤目錄結構可無限制層級創(chuàng)建，保存移動復制文件時遞歸所選文件夾層級等等。
使用技術：java+springboot+freemark+jpa+MySQL+maven
