第三章 （7）消费端自定义监听

消费者

package club.yunqiang.rabbitmqapi.consumer;

import com.rabbitmq.client.*;
import com.rabbitmq.client.Consumer;

import java.io.IOException;

/**

public class MyConsumer extends DefaultConsumer {


    /**
     * Constructs a new instance and records its association to the passed-in channel.
     *
     * @param channel the channel to which this consumer is attached
     */
    public MyConsumer(Channel channel) {
        super(channel);
    }

    @Override
    public void handleDelivery(String consumerTag, Envelope envelope, AMQP.BasicProperties properties, byte[] body) throws IOException {
        System.out.println("---- consume message ----");
        System.err.println("consumerTag:" + consumerTag);
        System.err.println("envelope:" + envelope);
        System.err.println("properties:" + properties);
        System.err.println("body:" + new String(body));
    }
}

生产端

package club.yunqiang.rabbitmqapi.consumer;

import com.rabbitmq.client.*;

import java.io.IOException;
import java.util.concurrent.TimeoutException;

/**

public class Producer {

    public static void main(String[] args) throws IOException, TimeoutException {
        ConnectionFactory connectionFactory = new ConnectionFactory();
        connectionFactory.setPort(5672);
        connectionFactory.setVirtualHost("/");
        connectionFactory.setHost("localhost");

        Connection connection = connectionFactory.newConnection();

        Channel channel = connection.createChannel();

        String exchange = "test_consumer_exchange";
        String routingKey = "consumer.save";

        String msg = "Hello Rabbit MQ Consumer Message";
        for (int i = 0; i < 5; i++) {
            channel.basicPublish(exchange, routingKey, true, null, msg.getBytes());
        }
    }
