如何通过java代码使用Kafka连接器？

<dependency>
    <groupId>org.apache.kafka</groupId>
    <artifactId>kafka-clients</artifactId>
    <version>2.8.0</version>
</dependency>

Properties props = new Properties();
props.put("bootstrap.servers", "localhost:9092");
props.put("key.serializer", "org.apache.kafka.common.serialization.StringSerializer");
props.put("value.serializer", "org.apache.kafka.common.serialization.StringSerializer");

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

KafkaConsumer<String, String> consumer = new KafkaConsumer<>(props);

ProducerRecord<String, String> record = new ProducerRecord<>("topic-name", "key", "value");
producer.send(record);

consumer.subscribe(Collections.singletonList("topic-name"));
ConsumerRecords<String, String> records = consumer.poll(Duration.ofMillis(100));
for (ConsumerRecord<String, String> record : records) {
    System.out.println("Received message: " + record.value());
}
