AWS S3 - how to enable regional endpoints for regions other than us-east-1?-CodePudding

The purpose of enableRegionalUsEast1Endpoint method associated with AmazonS3ClientBuilder in aws S3 SDK is to (see here):

"Enable resolving region us-east-1 as a regional endpoint instead of defaulting to the global endpoint"

But I do not see any similar methods that can enable resolving to any other regional endpoint, apart from us-east-1.

Question: What is the way to enable regional endpoint with AWS Java SDK, for regions other than us-east-1?

Context: My end goal is to be able to generate presigned URLs with regional domain e.g. https://<BUCKET_NAME>.s3.us-west-2.amazonaws.com/<KEY>....

CodePudding user response：

Each AWS client can be configured to use a specific endpoint within a region by calling the withEndpointConfiguration method when creating the client.

For example, to configure the Amazon S3 client to use the Europe (Ireland) Region, use the following code.

AmazonS3 s3 = AmazonS3ClientBuilder.standard()
 .withEndpointConfiguration(new EndpointConfiguration(
      "https://s3.eu-west-1.amazonaws.com",
      "eu-west-1"))
 .withCredentials(CREDENTIALS_PROVIDER)
 .build();
