java - 遵循 AWS 教程时对 UnknownResourceException 进行故障排除

Question

我正在尝试关注this AWS 教程。但我在“此时您可以成功运行 GreeterWorker”时遇到了麻烦。因为我收到了 UnknownResourceException。

Exception in thread "main" com.amazonaws.services.simpleworkflow.model.UnknownResourceException: Unknown domain: helloWorldWalkthrough (Service: AmazonSimpleWorkflow; Status Code: 400; Error Code: UnknownResourceFault; Request ID: xxxxx)

采取的步骤

• 通过将 SimpleWorkflowFullAccess IAM 策略附加到我的 AWS 用户解决了权限异常问题。
• 已验证 helloWorldWalkthrough 是否已在 SWF 仪表板上注册
• 注册了新的 helloWorldWalkthrough2 域，发生了同样的错误

本教程没有介绍将 SimpleWorkflowFullAccess 策略附加到 AWS 用户的步骤，因此我想知道是否有类似的未记录步骤来允许我的用户找到此域。

我的代码是从教程中的 GreeterWorker 类复制/粘贴的。

import com.amazonaws.ClientConfiguration;
import com.amazonaws.auth.AWSCredentials;
import com.amazonaws.auth.BasicAWSCredentials;
import com.amazonaws.services.simpleworkflow.AmazonSimpleWorkflow;
import com.amazonaws.services.simpleworkflow.AmazonSimpleWorkflowClient;
import com.amazonaws.services.simpleworkflow.flow.ActivityWorker;
import com.amazonaws.services.simpleworkflow.flow.WorkflowWorker;

public class GreeterWorker  {
   public static void main(String[] args) throws Exception {
     ClientConfiguration config = new ClientConfiguration().withSocketTimeout(70*1000);

     String swfAccessId = System.getenv("AWS_ACCESS_KEY_ID");
     String swfSecretKey = System.getenv("AWS_SECRET_KEY");
     AWSCredentials awsCredentials = new BasicAWSCredentials(swfAccessId, swfSecretKey);

     AmazonSimpleWorkflow service = new AmazonSimpleWorkflowClient(awsCredentials, config);
     service.setEndpoint("https://swf.us-east-1.amazonaws.com");

     String domain = "helloWorldWalkthrough";
     String taskListToPoll = "HelloWorldList";

     ActivityWorker aw = new ActivityWorker(service, domain, taskListToPoll);
     aw.addActivitiesImplementation(new GreeterActivitiesImpl());
     aw.start();

     WorkflowWorker wfw = new WorkflowWorker(service, domain, taskListToPoll);
     wfw.addWorkflowImplementationType(GreeterWorkflowImpl.class);
     wfw.start();
   }
}

您需要使用控制台或通过 API 调用创建域。域不会自动创建。
