今天來整合一下SpringBoot和阿里云OSS對象存儲服務(wù)。
一、配置OSS服務(wù)
先在阿里云開通對象存儲服務(wù)，拿到AccessKeyId、AccessKeySecret。
創(chuàng)建你的bucket(存儲空間)，相當(dāng)于一個一個的文件夾目錄。按業(yè)務(wù)需求分類存儲你的文件，圖片，音頻，app包等等。創(chuàng)建bucket是要選擇該bucket的權(quán)限，私有，公共讀，公共讀寫，按需求選擇。創(chuàng)建bucket時對應(yīng)的endpoint要記住，上傳文件需要用到。
可以配置bucket的生命周期，比如說某些文件有過期時間的，可以配置一下。
二、代碼實現(xiàn)
引入依賴包

返回的List是文件上傳之后文件的文件名集合。
到此就整合完成了。可以登錄OSS控制臺查看對應(yīng)的文件。更多相關(guān)SpringBoot整合阿里云OSS內(nèi)容請搜索服務(wù)器之家以前的文章或繼續(xù)瀏覽下面的相關(guān)文章希望大家以后多多支持服務(wù)器之家！
