在弹性beantalk上部署Web app spring的问题。返回404

这是我的项目的GitHub，当我将其部署在亚马逊网络服务（elasticbeanstalk）上并尝试打开它时，显然在Tomcat服务器上仅返回404即可。 我已经尝试了一切，将项目导出到war文件中。

这是应用程序代码

@SpringBootApplication
public class Application extends SpringBootServletInitializer {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

    @Bean
    public RequestContextListener requestContextListener() {
        return new RequestContextListener();
    }

编辑： 在启动Servlet Engine：Apache Tomcat / 8.5时，该资源在localhost中的工作率为100％，并且与AWS上的版本相同。

这是来自AWS的日志，有什么想法吗？

您的源代码包是什么样的？ The docs state，归档文件的要求是，它必须“ [不包括父文件夹或顶级目录”，但您的GitHub存储库具有顶级目录。您可能还希望enable CloudWatch logs or retrieve the instance log来更好地了解Web服务器在哪里寻找文件。

这里有一个example bundle structure可能会有所帮助。

在您的代码中，我看到您在application.properties中将server.port设置为8081。尝试删除此行以使其在默认端口上运行。

编辑：

关于文档（https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/java-se-nginx.html），在我看来，Beanstalk默认情况下在端口5000上进行侦听。因此，您现在可以执行以下任一操作：

  1. 将应用程序的server.port属性设置为5000，或
  2. 通过将PORT环境变量设置为与应用程序的端口（在您的情况下为8081）相匹配，来覆盖Beanstalk实例的默认值。

解决了，我已经更改了rds设置安全性
