如何同时创建一个组件--一个kafka消费者和一个kafka生产者？

import org.apache.kafka.clients.consumer.ConsumerRecords;
import org.apache.kafka.clients.consumer.ConsumerRecord;
import org.apache.kafka.clients.consumer.KafkaConsumer;
import org.apache.kafka.clients.producer.Producer;
import org.apache.kafka.clients.producer.ProducerRecord;
import org.apache.kafka.clients.producer.KafkaProducer;
import java.util.Properties;

public class KafkaConsumerProducerExample {
    public static void main(String[] args) {
        // Kafka消费者配置
        Properties consumerProps = new Properties();
        consumerProps.put("bootstrap.servers", "kafka-server1:9092,kafka-server2:9092");
        consumerProps.put("group.id", "my-consumer-group");
        consumerProps.put("key.deserializer", "org.apache.kafka.common.serialization.StringDeserializer");
        consumerProps.put("value.deserializer", "org.apache.kafka.common.serialization.StringDeserializer");
        KafkaConsumer<String, String> consumer = new KafkaConsumer<>(consumerProps);
        consumer.subscribe(Arrays.asList("my-topic"));

        // Kafka生产者配置
        Properties producerProps = new Properties();
        producerProps.put("bootstrap.servers", "kafka-server1:9092,kafka-server2:9092");
        producerProps.put("key.serializer", "org.apache.kafka.common.serialization.StringSerializer");
        producerProps.put("value.serializer", "org.apache.kafka.common.serialization.StringSerializer");
        Producer<String, String> producer = new KafkaProducer<>(producerProps);

        // 消费消息并发送消息
        try {
            while (true) {
                ConsumerRecords<String, String> records = consumer.poll(100);
                for (ConsumerRecord<String, String> record : records) {
                    // 处理消费的消息
                    System.out.printf("消费者消费消息：topic = %s, partition = %s, offset = %d, key = %s, value = %s%n",
                            record.topic(), record.partition(), record.offset(), record.key(), record.value());

                    // 发送消息
                    ProducerRecord<String, String> producerRecord = new ProducerRecord<>("my-topic", record.key(), record.value());
                    producer.send(producerRecord);
                }
            }
        } finally {
            consumer.close();
            producer.close();
        }
    }
}
