Question

我们正在创建一个包含多个活动的工作流程。其中一项活动是直接调用Lambda函数。 Lambda函数在不使用工作流的情况下正确执行（使用AWS Lambda控制台）。当使用SWF调用它时，函数不会被调度，也不会抛出任何错误。

Lambda函数的骨架如下。

public String handleRequest(String path, Context context) {
        System.out.println("unknown status");
        return "unknown status";
    }

工作流程实施

public class WorkflowAImpl implements WorkflowA {

    private ActivityOneClient processClient = new ActivityOneClientImpl();
    private ActivityTwoClient filterClient = new ActivityTwoClientImpl();

    @Override
    public Promise<String> process(String BucketNameFromMain,
            String Message) {
        WorkflowStatistics statistics = new WorkflowStatistics();
        DecisionContextProvider context = new DecisionContextProviderImpl();
        DecisionContext decisionContext = context.getDecisionContext();
        String workflowName = context.getDecisionContext().getWorkflowContext()
                .getWorkflowExecution().getWorkflowId();
        String workflowId = context.getDecisionContext().getWorkflowContext()
                .getWorkflowExecution().getRunId();
        BucketName = BucketNameFromMain;
        Promise<String> FirstDone = FirstActivity();
        Promise<String> SecondDone = translateMessageActivity(FirstDone,decisionContext);

        Promise<String> ThirdDone = insertMessageActivity(SecondDone);

        return ThirdDone;

    }

    @Asynchronous
    public Promise<String> FirstActivity() {
        Promise<String> FirstDone = processClient.ProcessMessage();
        return FirstDone;
    }

    @Asynchronous
    public Promise<String> insertMessageActivity(Promise<String> SecondDone) {
        Promise<String> ThirdDone = filterClient.FilterMessage();
        return ThirdDone;
    }

    @Asynchronous
    public Promise<String> translateMessageActivity(Promise<String> FirstDone,DecisionContext decisionContext) {
        LambdaFunctionClient lambdaClient =decisionContext.getLambdaFunctionClient();
        Promise<String> SecondDone =lambdaClient.scheduleLambdaFunction("LambdaFunctionName",inputData);
        return SecondDone;
    }



}

正在执行第一项活动。之后，它不会安排lambda函数。请帮助

参考：http://docs.aws.amazon.com/amazonswf/latest/awsflowguide/lambda-task.html https://github.com/aws/aws-sdk-java/tree/master/src/samples/AwsFlowFramework/src/com/amazonaws/services/simpleworkflow/flow/examples/hellolambda

AWS Lambda函数未在简单工作流（SWF）中执行
