无法检索请求的元数据/ latest / meta-data / public-hostname

标签： spring-boot amazon-elastic-beanstalk spring-cloud-stream spring-cloud-aws

我正在将带有spring-cloud-stream和活页夹的springboot应用程序部署到AWS Kinesis。 如果将beantalk配置为公共ip，则将其部署在aws弹性beantalk上时，该应用程序将正常运行。 当我们使用专用ip设置beantalk时，应用程序将在部署时引发警告，因为无法从aws获取一些元数据。

为什么要尝试获得这些资源？ 有一些解决方法可以删除此警告？

这些是在部署应用程序且在ec2上未设置公共ip时引发的警告。

此异常在Amazon SDK中发生。如果您根本不喜欢stacktrace，则可以将日志记录配置更新为仅以com.amazonaws的错误级别报告。如果您运行的EC2实例不需要任何实例数据，则可以添加或更新注释

@EnableAutoConfiguration(exclude = {ContextInstanceDataAutoConfiguration.class})

关于您的一个配置类。
