我们可以使用 java 和 spring 通过 API 引导从 AWS EFS 上传和下载文件吗？

Question

Wanted to know can we use java and spring boot to upload files through an API

I tried to get the details of integration of EFS with spring boot from AWS website but no luck

Answer 1

There is no direct way to upload/download files to AWS EFS from local system. You need to mount the EFS file system locally using amazon-efs-utils package and then perform normal file operations using Java File IO .

More details regarding mounting EFS file system here

Answer 2

You need to use either
AWS Transfer family

https://docs.aws.amazon.com/AWSJavaSDK/latest/javadoc/com/amazonaws/services/transfer/AWSTransferClient.html

or AWS Data sync

https://docs.aws.amazon.com/AWSJavaSDK/latest/javadoc/com/amazonaws/services/datasync/AWSDataSyncClient.html

Currently spring cloud aws does not have support for efs, but has for s3 https://docs.awspring.io/spring-cloud-aws/docs/current/reference/html/index.html#downloading-files
