【问题描述】：

使用 Spring Cloud Hoxton.SR4 和 Spring Boot 2.2.9.RELEASE 库，当我在本地环境中针对 localstack 运行时，我的 Spring Boot 微服务正确启动并运行良好，但是当我升级到 Hoxton.SR7 时，我得到了堆栈跟踪如下：

在针对 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？

【参考方案1】：

这是直接从 AWS SDK 记录的警告消息，在 Spring Cloud AWS 中我们无法控制它。在documentation 之后，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

【讨论】：

我在尝试调试为什么 @ConfigurationProperties 对象未绑定到属性源并在我们尝试在 @Configuration 类中引用它们以创建 AWS 客户端 bean 时返回空值时遇到了这个问题。我已经在github.com/spring-cloud/spring-cloud-aws/issues/641 记录了这个问题。我在github.com/spring-cloud/spring-cloud-aws/issues/640 中看到2.2.3.RELEASE 从ApplicationContextAware 移到BeanFactoryPostProcessor 以管理AWS bean，这可能会破坏应用程序的启动。有什么想法吗？
