spring-cloud-stream - 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，我将无法连接到 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访问 key ID 和 secret 访问 key 设置为 [默认] 配置文件时，应用程序才能工作。否则，它无法通过抛出此异常连接到 AWS 资源:

我尝试了以下选项，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

套装cloud.aws.credentials.accessKey和 cloud.aws.credentials.secretKey在 application.yml文件。

我解决了这个问题。

我想 spring-cloud-starter-aws无法自动配置。
所以我像这样以编程方式设置访问 key 和 secret key :

@Configuration
class AWSS3Configuration {

  @Value("\${cloud.aws.credentials.access-key}")
  val accessKey: String = ""

  @Value("\${cloud.aws.credentials.secret-key}")
  val secretKey: String = ""

  @Bean
  fun amazonS3(): AmazonS3 =
    AmazonS3ClientBuilder.standard()
      .withCredentials(AWSStaticCredentialsProvider(BasicAWSCredentials(accessKey, secretKey)))
      .build()

}
