如何将 Spring 启动应用程序 war 部署到 AWS Elastic Beanstalk？
How to deploy Spring Boot application war to AWS Elastic Beanstalk?
之前也有人问过类似的问题，但是我看到的答案都是"It just works!"。可悲的是，它不适合我。
我的问题是：当我将一个 war 文件部署到 Elastic Beanstalk 时，我从 catalina.out 中得到一堆错误，说 "Failed to start component"（下面的日志）。
我已经完成了 Spring 引导教程，正在使用 Gradle 进行构建，并添加了 'war' 插件，因此我可以构建一个可部署的 war 文件.当 运行 在本地时，我可以访问 "Greetings from Spring Boot!"。除了生成可部署的 war 文件并尝试更改项目的监听端口之外，我没有对该项目进行任何更改。
我搞砸了负载均衡器配置，允许端口 8080 入站和出站，并向 IAM 添加了 "FullAccessEC2Instance" 安全角色，我认为我没有正确设置权限（但这不是'没有 'it just works' 的感觉）。
目前我正在转动轮子猜测现在该做什么。我正在考虑测试部署到 Heroku，看看它是否也有问题，或者我的 AWS 配置是否有问题。

原来解决方案是在 build.grade 的依赖部分中只包含 Jetty 或 Tomcat。这在文档中似乎是正确的，但我误解了我的意思是删除 either/or，具体取决于我想如何部署它。
之前也有人问过类似的问题，但是我看到的答案都是"It just works!"。可悲的是，它不适合我。
我的问题是：当我将一个 war 文件部署到 Elastic Beanstalk 时，我从 catalina.out 中得到一堆错误，说 "Failed to start component"（下面的日志）。
