如何访问 Codenvy Spring 启动网络控制器？

Question

我正在测试 Codenvy (https://codenvy.io) 并制作了一个非常简单的 Spring 启动网络控制器：

@Controller
@EnableAutoConfiguration
public class SampleController { 

@RequestMapping("/")
@ResponseBody
String home() {
    return "Hello World!";
}

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

}

Pom.xml:

 <parent>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-parent</artifactId>
  <version>1.4.2.RELEASE</version>
 </parent>
 <dependencies>
 <dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
  </dependency>

启动正常：

在我的浏览器中，项目的 url 是：https://codenvy.io/dashboard/#/ide/tyvain/BOTS

简单（愚蠢）的问题：我如何调用这个 URL 来测试它？？

Answer 1

这不是一个愚蠢的问题:)

当您在云端 IDE 时，应用程序运行处于另一个运行时间之内。对于codenvy，我们使用Docker个容器作为运行时间。 Docker 允许您启动您的应用程序，但随后使用临时端口范围获取您服务器的内部端口号并使其可供外部世界使用。它将端口映射到从 32765+ 范围开始的另一个数字。这样做是因为如果在同一个端口上的两个工作区运行中有两台服务器，它们会相互冲突，因此 docker 将端口置于此范围内以避免端口冲突。

您需要设置一个带预览的命令URL，以便在您运行时向您的服务器显示 URL。我们有很多关于如何在 www.eclipse.org 生成预览 URL 的文档。而且，您还可以在示例中查看命令的结构（尝试 Maven spring 示例）。
