如何列出写到某个kafka主题的生产者

import org.apache.kafka.clients.producer.KafkaProducer;
import org.apache.kafka.clients.producer.Producer;
import org.apache.kafka.clients.producer.ProducerRecord;

Properties props = new Properties();
props.put("bootstrap.servers", "kafka-broker1:9092,kafka-broker2:9092"); // Kafka集群的地址
props.put("key.serializer", "org.apache.kafka.common.serialization.StringSerializer");
props.put("value.serializer", "org.apache.kafka.common.serialization.StringSerializer");

Producer<String, String> producer = new KafkaProducer<>(props);

String topic = "my-topic";
String key = "key1";
String value = "Hello, Kafka!";
ProducerRecord<String, String> record = new ProducerRecord<>(topic, key, value);

producer.send(record, new Callback() {
    public void onCompletion(RecordMetadata metadata, Exception exception) {
        if (exception != null) {
            // 发送失败的处理逻辑
        } else {
            // 发送成功的处理逻辑
        }
    }
});

producer.close();
