Using the Default Credential Provider Chain
|
|
|
|
When you initialize a new service client without supplying any arguments,
|
|
the AWS SDK for Java attempts to find AWS credentials by using the default credential provider chain
|
|
implemented by the DefaultAWSCredentialsProviderChain class.
|
|
The default credential provider chain looks for credentials in this order:
|
|
|
|
1. Environment variables–AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY.
|
|
The AWS SDK for Java uses the EnvironmentVariableCredentialsProvider class to load these credentials.
|
|
2...
|
|
|
|
...
|
|
|
|
When using temporary credentials obtained from STS, create a BasicSessionCredentials object,
|
|
passing it the STS-supplied credentials and session token.
|
|
|
|
BasicSessionCredentials sessionCredentials = new BasicSessionCredentials(
|
|
session_creds.getAccessKeyId(),
|
|
session_creds.getSecretAccessKey(),
|
|
session_creds.getSessionToken());
|
|
|
|
AmazonS3 s3 = AmazonS3ClientBuilder
|
|
.standard()
|
|
.withCredentials(new AWSStaticCredentialsProvider(sessionCredentials))
|
|
.build();
