rabbitmq-广播模型

生产者：

package com.gavin.mq.fanout;

import com.gavin.utils.RabbitMQUtils;
import com.rabbitmq.client.Channel;
import com.rabbitmq.client.Connection;
import com.rabbitmq.client.MessageProperties;
import org.junit.Test;

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

/**
 * 广播模型：生产者发送到交换机，交换机决定发送到哪个队列，生产者无法决定
 * 每个消费者都有自己的队列
 * 每个队列都要绑定到交换机
 */
public class WorkProvider {
    @Test
    public void testSendMessage() throws IOException, TimeoutException {

        Connection connection = RabbitMQUtils.getConnection();
        Channel channel = connection.createChannel();
        //声明交换机 参数1：交换机名称
        channel.exchangeDeclare("logs","fanout");
        channel.basicPublish("logs","", MessageProperties.PERSISTENT_BASIC,("hello work queue").getBytes());
        RabbitMQUtils.close(channel,connection);
    }
}

消费者：

package com.gavin.mq.fanout;

import com.gavin.utils.RabbitMQUtils;
import com.rabbitmq.client.*;

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

public class WorkConsumer {
    public static void main(String[] args) throws IOException, TimeoutException {
        Connection connection = RabbitMQUtils.getConnection();
        Channel channel = connection.createChannel();
        channel.exchangeDeclare("logs","fanout");
        /**
         * 临时队列
         */
        String tempQueue = channel.queueDeclare().getQueue();
        /**
         * 绑定交换机和队列
         */
        channel.queueBind(tempQueue,"logs","");
        channel.basicConsume(tempQueue,true,new DefaultConsumer(channel){
            @Override
            public void handleDelivery(String consumerTag, Envelope envelope, AMQP.BasicProperties properties, byte[] body) throws IOException {
                System.out.println(new String(body));
            }
        });
    }
}
