无法从链中的任何提供商加载 AWS 凭证 Spring Cloud Stream Kinesis Binder

Question

如果不使用系统级别的默认配置，我无法连接到 Spring Cloud Stream Kinesis Binder (1.2.0.RELEASE) 中的 AWS kinesis。仅当系统已配置为使用默认配置文件并且使用 [default] 配置文件设置访问密钥 ID 和秘密访问密钥时，应用程序才能工作。否则，将无法通过抛出此异常来连接到 AWS 资源：

我尝试过以下选项，但没有一个对我有用：

• 设置环境变量AWS_ACCESS_KEY_ID和AWS_SECRET_ACCESS_KEY
• 设置 Java 系统属性aws.accessKeyId和aws.secretKey
• 设置cloud.aws.credentials.accessKey并cloud.aws.credentials.secretKey在application.yml文件中。

由于某种原因，AWSCredentialProvider bean 似乎加载不正确，因此我可以通过设置以下 bean 来临时解决此问题。这不是一个正确的解决方案，但它确实解除了我的工作障碍：

@Configuration
public class AWSCredentialProvider {
  @Value("${aws.access-key}")
  protected String accessKey;

  @Value("${aws.secret-key}")
  protected String secretKey;

  @Bean
  @Primary
  public AWSCredentialsProvider buildAWSCredentialsProvider() {
    AWSCredentials awsCredentials = new BasicAWSCredentials(accessKey, secretKey);
    return new AWSStaticCredentialsProvider(awsCredentials);
  }
}
