云存儲文件重命名功能

云存儲文件重命名功能目錄技術(shù)原理實(shí)現(xiàn)步驟功能描述功能測試2技術(shù)原理3（1）視圖層：顯示文件重命名的輸入框（2）控制層：接收視圖層的消息，向服務(wù)層發(fā)送文件和文件夾重命名參數(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服務(wù)對文件重命名，并將結(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
