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

我正在为 AWS Kinesis 部署带有 spring-cloud-stream 和 binder 的 springboot 应用程序。如果 beanstalk 配置了公共 ip，则该应用程序在部署在 aws elastic beanstalk 上时工作正常。当我们将 beanstalk 设置为私有 ip 时，应用程序会在部署时抛出警告，因为无法从 aws 获取一些元数据。

为什么要尝试获取这些资源？有一些解决方法可以删除此警告吗？

这些是在部署应用程序并且没有在 ec2 上设置公共 ip 时抛出的警告。

mvn spring-boot:运行vs运行

我正在使用intelliJ上的livereload测试spring-boot-devtools.我有简单的SpringBootApplication工作正常.

当我从maven命令"mvn spring-boot:run"启动应用程序时,一切正常,除了livereload服务器不启动.控制台上没有消息,Chrome扩展显示错误,无法连接到livereload服务器.

如果我启动应用程序(右摩丝按钮/运行Application.java),所有工作正常甚至livereload服务器.消息显示在控制台上,浏览器可以连接到livereload服务器.

从正确的慕斯按钮启动应用程序/运行Application.java

控制台消息
