为Application Load Balancer创建的ApplicationLoadBalancedFargateService添加Cloud Map服务，可以按照以下步骤进行：

1. 在应用程序中创建一个Cloud Map服务。可以使用AWS控制台创建服务或者使用AWS CLI命令创建服务。

2. 使用ApplicationLoadBalancedFargateService的“withServiceRegistry”方法，将刚刚创建的Cloud Map服务与ALB Fargate Service进行关联。

以下是一个示例代码：

import java.util.*;

import software.amazon.awssdk.services.ecs.*;
import software.amazon.awssdk.services.ecs.model.*;
import software.amazon.awssdk.services.servicediscovery.*;
import software.amazon.awssdk.services.servicediscovery.model.*;

public class AddCloudMapToALB {

   public static void main(String[] args) {

      String clusterARN = "arn:aws:ecs:region:aws_account_id:cluster/my-cluster";
      String serviceName = "my-service";
      String namespaceId = "aws-cloud-map-namespace-id";
      String serviceId = "aws-cloud-map-service-id";

      // Create ECS client and describe cluster
      EcsClient ecsClient = EcsClient.builder().build();
      DescribeClustersRequest clusterRequest = DescribeClustersRequest.builder()
              .clusters(clusterARN)
              .build();
      DescribeClustersResponse clusterResponse = ecsClient.describeClusters(clusterRequest);
      Cluster cluster = clusterResponse.clusters().get(0);

      // Create Service Discovery client and get namespace ID
      ServiceDiscoveryClient discoveryClient = ServiceDiscoveryClient.builder().build();
      GetNamespaceRequest nsRequest = GetNamespaceRequest.builder()
              .id(namespaceId)
              .build();
      GetNamespaceResponse nsResponse = discoveryClient.getNamespace(nsRequest);
      Namespace namespace = nsResponse.namespace();

      // Associate the Cloud Map service with the ALB Fargate service
      ApplicationLoadBalancedFargateService.Builder serviceBuilder = ApplicationLoadBalancedFargateService.builder()
              .serviceName(serviceName)
              .cluster(cluster.clusterName())
              .desiredCount(1)
              .taskDefinition(cluster.activeServicesCount())
              .listener
