如何从同一个生产者向不同的Kafka主题和模式注册中心生成消息

import org.apache.kafka.clients.producer.*;

public class KafkaProducerExample {
    public static void main(String[] args) {
        // Kafka集群地址
        String bootstrapServers = "kafka1:9092,kafka2:9092,kafka3:9092";
        
        // KafkaProducer配置参数
        Properties props = new Properties();
        props.put("bootstrap.servers", bootstrapServers);
        props.put("key.serializer", "org.apache.kafka.common.serialization.StringSerializer");
        props.put("value.serializer", "org.apache.kafka.common.serialization.StringSerializer");

        // 创建Kafka生产者对象
        KafkaProducer<String, String> producer = new KafkaProducer<>(props);

        // 消息内容
        String message = "Hello, Kafka!";

        // 向主题A发送消息
        String topicA = "topicA";
        ProducerRecord<String, String> recordA = new ProducerRecord<>(topicA, message);
        producer.send(recordA, new Callback() {
            public void onCompletion(RecordMetadata metadata, Exception exception) {
                if (exception == null) {
                    System.out.println("消息成功发送到主题A，偏移量为：" + metadata.offset());
                } else {
                    System.out.println("发送消息到主题A失败：" + exception.getMessage());
                }
            }
        });

        // 向主题B发送消息
        String topicB = "topicB";
        ProducerRecord<String, String> recordB = new ProducerRecord<>(topicB, message);
        producer.send(recordB, new Callback() {
            public void onCompletion(RecordMetadata metadata, Exception exception) {
                if (exception == null) {
                    System.out.println("消息成功发送到主题B，偏移量为：" + metadata.offset());
                } else {
                    System.out.println("发送消息到主题B失败：" + exception.getMessage());
                }
            }
        });

        // 关闭Kafka生产者
        producer.close();
    }
}
