我正在尝试将Spring Boot应用程序部署到Tomcat,因为我想部署到AWS.我创建了一个WAR文件,但它似乎不在Tomcat上运行,即使它是可见的.

详细信息:
0.这是我的应用程序:

@Configuration
@ComponentScan
@EnableAutoConfiguration
public class App {
    public static void main(String[] args) {
        SpringApplication.run(SampleController.class, args);
    }
}

@Controller
@EnableAutoConfiguration
public class SampleController {
    @RequestMapping("/help")
    @ResponseBody
    String home() {
        String input = "Hi! Please use 'tag','check' and 'close' resources.";
        return input;
    }
}

application.properties有以下内容:

server.port=${port:7777}

1. 在阅读了许多页面和问题后,我在POM中添加了以下内容:

   http://maven.apache.org/xsd/maven-4.0.0.xsd"> 4.0.0

2. 我运行了"mvn package"并获得了WAR文件(大小为250Mb),我将其放入"webapps"文件夹中. …

我整理了一个简单的Eclipse Spring Boot Rest程序.只有几个返回一些字符串的端点.我正在使用Eclipse Gradle插件构建它.没有问题,它在Eclipse提供的Tomcat实例中运行良好.我也在原生Windows Tomcat上运行它.我使用部署功能使用tomcat Web应用程序管理器部署了.war文件.运行很好.然后我部署了一个ec2 ubuntu实例,并再次使用tomcat Web应用程序管理器并上传.war文件.其余程序正确显示在应用程序窗口中,但不会运行.我使用了以下网址,

HTTP://ec2-IP-Address/demo-0.0.1-SNAPSHOT/hello

我一直在买404.我很确定tomcat部署和ec2环境看起来是正确的,因为我可以在ec2实例中运行tomcat7-examples而没有任何问题.任何帮助,将不胜感激.
