如何使用java获取包含aws中文件的文件夹大小 [英] how to get folder size which consists of files in aws using java

问题描述

让我们以为我们有一个名称为"bucket1"的存储桶，里面有一个 名称为新文件夹"的文件夹 在新文件夹"中是文件
新文件夹/a1.pdf-->2mb
新文件夹/a2.pdf-->2mb
新文件夹/新文件夹2/b.pdf-> 3mb

lets think we have bucket with name "bucket1" and inside that having a folder with name 'new folder' Inside 'new folder' are files
new folder/a1.pdf-->2mb
new folder/a2.pdf-->2mb
new folder/new folder2/b.pdf-->3mb

当我们使用amazons3client.listObjects("bucket1"，新文件夹")----> 将返回其中每个"s3object"的文件和文件夹的列表 有一个大小"参数，我可以遍历所有这些s3对象，而我 可以获取文件夹大小，但操作繁重.

when we use amazons3client.listObjects("bucket1","new folder")---->it will return the list of files and folders inside that for each 's3object' there is 'size' parameter i can loop through all those s3 objects and i can get folder size but it is heavy operation.

/*您是否可以通过其他任何方式获取文件夹大小*/

/* will you please any another way to get folder size*/

推荐答案

没有其他方法.

文件夹"在S3中不是容器，因此它本身没有大小.

The "folder" is not a container in S3 so it has no size, itself.
