Question

我正在测试Codenvy（https://codenvy.io）并制作了一个非常简单的Spring Boot Web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);
}

}

的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>

启动就可以了：

简单（愚蠢）问题：如何调用此URL来测试它？

Answer 1

这不是一个愚蠢的问题：）

当您在云IDE中时，应用程序在另一个运行时内运行。在codenvy的情况下，我们使用Docker容器作为运行时。 Docker允许您启动应用程序，但随后使用临时端口范围获取服务器的内部端口号并使其可供外部使用。它将端口映射到另一个从32765+范围开始的数字。这样做是因为如果两个工作区中有两个服务器在同一个端口上运行，它们都会相互冲突，因此docker将端口放入此范围以避免端口冲突。

您需要设置一个带有previewURL的命令，该命令会在您运行服务器时显示服务器的URL。我们有很多关于如何在www.eclipse.org上生成预览URL的文档。但是，您也可以看到样本中命令的结构（尝试maven spring样本）。

这是你在问什么，寻找？

看起来变量是运行命令命令pallette的一部分
