这是我的项目 GitHub，当我将它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 工作正常。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：资源在 localhost 中 100% 工作，启动 Servlet 引擎：Apache Tomcat/8.5，它与 AWS 上的版本相同。

这是来自 AWS 的日志，有什么想法吗？

有消息吗？

【问题讨论】：

【参考方案1】：

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 默认侦听端口 5000。因此，此时您可以执行以下操作之一：

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

【讨论】：

我尝试使用默认端口 5000 将其替换为当前的 8081 但没有成功。【参考方案2】：

您的源包是什么样的？ The docs state 存档的要求是它必须“[n] 不包括父文件夹或***目录”，但您的 GitHub 存储库具有***目录。您可能还想enable CloudWatch logs or retrieve the instance logs 以更好地了解 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。

【讨论】：

您对具体问题有什么建议吗？检查源包的结构（.zip 或 .war）并确保代码位于 repo 的顶部，或在此处共享内容。或者分享你用来创建包的命令我已经加载了日志日志很有帮助，但我仍然认为您的 .zip 的结构不正确。你能打开 zip 并分享目录和文件结构的样子吗？这是zip文件的结构：spring-security-registration-master-->src-->main-->java,resources,webapp-->...【参考方案3】：

解决了，我改的是rds设置安全
