Kafka监听器:轮询间隔:如何调度kafka consumer poll()，间隔15分钟

import java.util.concurrent.Executors;
import java.util.concurrent.ScheduledExecutorService;
import java.util.concurrent.TimeUnit;

public class KafkaListener {
    private static final int POLL_INTERVAL = 15; // 轮询间隔，单位为分钟

    public static void main(String[] args) {
        // 创建一个ScheduledExecutorService实例
        ScheduledExecutorService executorService = Executors.newSingleThreadScheduledExecutor();

        // 使用scheduleAtFixedRate方法来定时执行任务
        executorService.scheduleAtFixedRate(() -> {
            // 创建Kafka Consumer实例
            KafkaConsumer<String, String> consumer = createConsumer();

            // 调用poll()方法获取消息
            ConsumerRecords<String, String> records = consumer.poll(Duration.ofMillis(100));

            // 处理消息
            for (ConsumerRecord<String, String> record : records) {
                // 处理消息的逻辑
                System.out.println("Received message: " + record.value());
            }

            // 关闭Consumer
            consumer.close();
        }, 0, POLL_INTERVAL, TimeUnit.MINUTES);
    }

    private static KafkaConsumer<String, String> createConsumer() {
        // 创建Kafka Consumer实例的代码
        // 这里可以根据实际情况配置Consumer的属性，如bootstrap.servers、group.id等

        return consumer;
    }
}
