如何输出kafka的消费者属性？

import org.apache.kafka.clients.consumer.*;
import org.apache.kafka.common.*;
import java.util.*;

public class KafkaConsumerExample {
    public static void main(String[] args) {
        Properties props = new Properties();
        props.put("bootstrap.servers", "kafka-broker1:9092,kafka-broker2:9092");
        props.put("group.id", "my-consumer-group");
        props.put("key.deserializer", "org.apache.kafka.common.serialization.StringDeserializer");
        props.put("value.deserializer", "org.apache.kafka.common.serialization.StringDeserializer");

        KafkaConsumer<String, String> consumer = new KafkaConsumer<>(props);
        consumer.subscribe(Arrays.asList("my-topic"));

        while (true) {
            ConsumerRecords<String, String> records = consumer.poll(Duration.ofMillis(100));
            for (ConsumerRecord<String, String> record : records) {
                System.out.println("Topic: " + record.topic());
                System.out.println("Partition: " + record.partition());
                System.out.println("Offset: " + record.offset());
                System.out.println("Key: " + record.key());
                System.out.println("Value: " + record.value());
                System.out.println();
            }
        }
    }
}
