生产者

    private static final String TASK_QUEUE_NAME = "ack_queue";
    public static void main(String[] argv) throws Exception {
        try (Channel channel = RabbitMqUtils.getChannel()) {
        channel.queueDeclare(TASK_QUEUE_NAME, false, false, false, null);
        Scanner sc = new Scanner(System.in);

                channel.basicPublish("", TASK_QUEUE_NAME, null, message.getBytes("UTF-8"));
                System.out.println("生产者发出消息" + message);
             }
         }

import com.aa.Utils.SleepUtils;
import com.rabbitmq.client.CancelCallback;
import com.rabbitmq.client.Channel;

        DeliverCallback deliverCallback = (consumerTag, delivery) -> {
            System.out.println("C2消息等待消息, 处理时间较长");
            String message = new String(delivery.getBody(), StandardCharsets.UTF_8);
            SleepUtils.sleep(30);
            System.out.println("收到消息 :" + message);

            /*
             1.消息标记 tag
             2.是否批量应答未应答消息
            */

        boolean autoAck = false;
        channel.basicConsume(TASK_QUEUE_NAME, autoAck, deliverCallback, cancelCallback);

睡眠工具类

public class SleepUtils {
    public static void sleep(int second){
        try {
            Thread.sleep(1000*second);
        } catch (InterruptedException _ignored) {
            Thread.currentThread().interrupt();
        }
    }
}
