我用

AWSSecurityTokenServiceClient sts_client = new AWSSecurityTokenServiceClient(),

并自动设置了默认区域（全局）。但是此构造函数已弃用，建议使用：

AWSSecurityTokenServiceClientBuilder.

我也希望它使用默认区域。我写：

AWSSecurityTokenService stsClient = AWSSecurityTokenServiceClientBuilder.standard().withCredentials(new AWSStaticCredentialsProvider(awsCredentials)).build();

但我有一个例外：

com.amazonaws.SdkClientException: Unable to find a region via the region provider chain. Must provide an explicit region in the builder or setup environment to supply a region.

我从未听说过 Global 区域，但要使用新的非弃用 Builder 方法指定默认区域，您可以使用：

.withRegion(Regions.DEFAULT_REGION)

所以你的命令是：

AWSSecurityTokenService stsClient = AWSSecurityTokenServiceClientBuilder.standard() .withCredentials(new AWSStaticCredentialsProvider(awsCredentials)) .withRegion(Regions.DEFAULT_REGION.getName()) .build();

仅供参考 - 在我的 Regions 枚举版本中，DEFAULT_REGION是US_WEST_2. 不要忘记

import com.amazonaws.regions.Regions;

编辑：知道您指定的区域无关紧要可能很有用。生成的 STS 凭证可以在所有地区使用（因此它们在某种意义上是“全球性的”）。
