云存儲(chǔ)還原文件功能

云存儲(chǔ)還原文件功能目錄技術(shù)原理實(shí)現(xiàn)步驟功能描述功能測(cè)試2技術(shù)原理3（1）視圖層：顯示還原文件界面（2）控制層：接收視圖層的消息，向服務(wù)層發(fā)送文件還原參數(shù)，并將服務(wù)層返回的結(jié)果發(fā)送到視圖層（3）服務(wù)層：調(diào)用swift接口將指定的文件還原到以前的位置，再將回收站的文件刪除，最后將處理結(jié)果返回給控制層功能描述4實(shí)現(xiàn)步驟5在cn/edu/sict/cloud/storage/service/SwiftStorageService.java添加如下代碼public
