要获取Apache Kafka的血统信息，可以使用Kafka的AdminClient API来实现。下面是一个示例代码，展示了如何获取Kafka的血统信息：

import java.util.Properties;
import org.apache.kafka.clients.admin.AdminClient;
import org.apache.kafka.clients.admin.AdminClientConfig;
import org.apache.kafka.clients.admin.ConsumerGroupDescription;
import org.apache.kafka.clients.admin.ConsumerGroupListing;
import org.apache.kafka.clients.admin.DescribeConsumerGroupsResult;
import org.apache.kafka.clients.admin.ListConsumerGroupsResult;
import org.apache.kafka.common.KafkaFuture;

public class KafkaLineageInfo {
    public static void main(String[] args) {
        // 设置Kafka的配置属性
        Properties props = new Properties();
        props.put(AdminClientConfig.BOOTSTRAP_SERVERS_CONFIG, "localhost:9092");

        // 创建AdminClient实例
        AdminClient adminClient = AdminClient.create(props);

        try {
            // 获取所有的消费者组
            ListConsumerGroupsResult listConsumerGroupsResult = adminClient.listConsumerGroups();
            KafkaFuture> groupsFuture = listConsumerGroupsResult.all();
            Iterable consumerGroups = groupsFuture.get();

            // 遍历每个消费者组
            for (ConsumerGroupListing consumerGroupListing : consumerGroups) {
                String groupId = consumerGroupListing.groupId();

                // 获取消费者组的描述信息
                DescribeConsumerGroupsResult describeConsumerGroupsResult = adminClient.describeConsumerGroups(groupId);
                KafkaFuture descriptionFuture = describeConsumerGroupsResult.describedGroups().get(groupId);
                ConsumerGroupDescription description = descriptionFuture.get();

                // 打印消费者组的血统信息
                System.out.println("Consumer Group: " + groupId);
                System.out.println("Members: " + description.members());
                System.out.println("State: " + description.state());
                System.out.println("Partitions: " + description.partitionAssignor());
                System.out.println();
            }
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            // 关闭AdminClient实例
            adminClient.close();
        }
    }
}

这段代码使用AdminClient来获取Kafka的消费者组列表，并对每个消费者组获取其描述信息，包括成员、状态和分区分配器。你可以根据自己的需求对血统信息进行进一步处理和分析。请确保在代码中设置正确的Kafka服务器地址和端口。
