生产者

package com.xuecheng.test.rabbitmq;

import com.rabbitmq.client.Channel;
import com.rabbitmq.client.Connection;
import com.rabbitmq.client.ConnectionFactory;

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

/**
 * @Classname Producer01
 * @Description rabbitmqd的入门程序
 * @Date 2020/2/20 18:20
 * @Created by mmz
 */
public class Producer01 {

    //队列常量
    private static final String QUEUE = "helloworld";

    public static void main(String[] args) {
        //通过连接工厂,创建新的连接
        ConnectionFactory connectionFactory = new ConnectionFactory();

        //设置参数
        connectionFactory.setHost("127.0.0.1");//ip地址
        connectionFactory.setPort(5672);//端口
        connectionFactory.setUsername("guest");
        connectionFactory.setPassword("guest");
        //设置虚拟机,一个mqf服务可以设置多个虚拟机,每个虚拟机就相当于独立的mq
        connectionFactory.setVirtualHost("/");

        //生产者和mq建立连接
        Connection connection = null;
        try {
            connection =  connectionFactory.newConnection();

            //创建会话通道,所有生产者和mq服务都在channel通道中
            Channel channel = connection.createChannel();
            //声明队列
            //参数
            channel.queueDeclare(QUEUE,true,false,false,null);
            //发送消息
            String message = "helloworld mmz";
            channel.basicPublish("",QUEUE,null,message.getBytes());
            System.out.println("send to mq" + message);
        } catch (Exception e) {
            e.printStackTrace();
        } finally {

        }
    }
}

消费者

package com.xuecheng.test.rabbitmq;

import com.rabbitmq.client.*;

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

/**
 * @Classname Consumer01
 * @Description 消费者
 * @Date 2020/2/21 15:02
 * @Created by mmz
 */
public class Consumer01 {

    private static final String QUEUE = "helloworld";

    public static void main(String[] args) throws IOException, TimeoutException {
        //通过连接工厂,创建新的连接
        ConnectionFactory connectionFactory = new ConnectionFactory();

        //设置参数
        connectionFactory.setHost("127.0.0.1");//ip地址
        connectionFactory.setPort(5672);//端口
        connectionFactory.setUsername("guest");
        connectionFactory.setPassword("guest");
        //设置虚拟机,一个mqf服务可以设置多个虚拟机,每个虚拟机就相当于独立的mq
        connectionFactory.setVirtualHost("/");


        //生产者和mq建立连接
        Connection connection = null;
        connection =  connectionFactory.newConnection();

        //创建会话通道,所有生产者和mq服务都在channel通道中
        Channel channel = connection.createChannel();

        //消费方法
        DefaultConsumer defaultConsumer = new DefaultConsumer(channel){
            //当接收到消息后,此方法将被调用
            @Override
            public void handleDelivery(String consumerTag, Envelope envelope, AMQP.BasicProperties properties, byte[] body) throws IOException {
                //获取交换机
                String exchange = envelope.getExchange();
                //消息id,mq在channel中用来标识消费的id,可以用于确认消息已经接收
                long deliveryTag =  envelope.getDeliveryTag();
                //消息内容
                String message = new String(body,"utf-8");
                System.out.println("receive message:" + message);
            }
        };

        //监听队列
        channel.queueDeclare(QUEUE,true,false,false,null);

        channel.basicConsume(QUEUE,true,defaultConsumer);
    }
}

消费者需要写一个接受函数
