通过 Boxfuse 将 Grizzly 应用程序部署到 AWS 失败

Question

我有一个 Grizzly 应用程序，我正在尝试使用 Boxfuse 将它部署到 AWS。 Grizzly 服务器是这样启动的：

String instanceIP = System.getProperty(BOXFUSE_INSTANCE_IP)
String port = System.getProperty(BOXFUSE_PORTS_HTTP)
String BASE_URI = "http://" + instanceIP + ":" + port;
System.out.println(BASE_URI);
final ResourceConfig rc = new ResourceConfig().packages("com.homer.web");
GrizzlyHttpServerFactory.createHttpServer(URI.create(BASE_URI), rc);

这一切都在本地运行良好（如果我转到 http://localhost:8080，我会看到我的“Hello World”页面）但是当我推送到 AWS 时，我收到了这个 Grizzly 错误：

我不知道我是否应该为 AWS 版本做任何不同的事情，但我认为重点是我不必这样做。任何帮助表示赞赏。谢谢！

在 AWS 上，用于单实例应用程序 BOXFUSE_INSTANCE_IP 包含该环境的应用程序的弹性 IP。在实例启动时，它仍然属于旧版本的应用程序（如果有），并且只有在运行状况检查通过后才会分配给该实例。
