spring-cloud-aws - 从 Hoxton.SR4 升级到 Spring Cloud Hoxton.SR7 后遇到错误

Question

使用 Spring Cloud Hoxton.SR4 和 Spring Boot 2.2.9.RELEASE 库，我的 Spring Boot 微服务正确启动并在我的本地堆栈上运行时运行良好本地环境，但是当我升级到 Hoxton.SR7 时，我得到以下堆栈跟踪:

当针对 localstack 运行时，我需要包含哪些新的或额外的配置/代码才能在我的本地环境中关闭此 EC2 检查？

Answer 1

这是一条直接从 AWS SDK 记录的警告消息，在 Spring Cloud AWS 内部我们无法控制它。正在关注documentation ，只需在 application.properties 配置文件中添加一行即可关闭此警告:

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