运行应用程序时出错 - “|WARN|无法检索令牌 com.amazonaws.SdkClientException：无法连接到服务端点：”

Question

过去几天，当我尝试在本地运行我的应用程序时，我一直收到这些错误。 我完全不知道如何解决这个问题。 知道可能是什么问题吗？ 下面是踪迹。 该应用程序使用 aws-sdk 11 并在 java 11 上运行。

Answer 1

问题是 SDK 现在在无法检索AWS 实例元数据时会记录警告。 使用环境变量指定您想要的 AWS 区域可能会有所帮助（我没有看到这个工作，但其他人有）：

export AWS_REGION=us-east-1

或者，Spring Cloud 团队建议取消警告：

https://github.com/spring-cloud/spring-cloud-aws/issues/556

https://github.com/juho9000/spring-cloud-aws/commit/24edbdc57086f1043d3a49f6c8841cc1751ee747

在应用程序启动时，出于其内部目的，Spring Cloud AWS 会使用 AWS SDK 提供的EC2MetadataUtils类检查应用程序是否在 AWS 云环境中运行。 从版本 1.11.678 开始，当在 AWS 环境之外进行此检查时，AWS 开发工具包会记录一条警告消息，但有异常。 通过在com.amazonaws.util.EC2MetadataUtils类上设置ERROR日志记录级别，可以隐藏此警告消息。

logging.level.com.amazonaws.util.EC2MetadataUtils=错误
