RabbitMQ通信实现（四）

 一、RabbitMQ生产者代码
 

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

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

/**

public class RabbitProducer {
    private static final String EXCHANGE_NAME="exchange_demo";
    private static final String ROUTING_KEY="routingkey_demo";
    private static final String QUEUE_NAME="queue_demo";
    private static final String IP_ADDRESS="localhost";
    private static final int PORT=5672;//RabbitMQ服务器的默认端口为5672
    public static void main(String[] args) throws IOException, TimeoutException {
        ConnectionFactory factory=new ConnectionFactory();
        factory.setHost(IP_ADDRESS);
        factory.setPort(PORT);
        factory.setUsername("root");
        factory.setPassword("root");
        Connection connection = factory.newConnection();//创建连接
        Channel channel = connection.createChannel();//创建信道
        //创建一个type="direct" 、持久化、非自动删除的交换机
        channel.exchangeDeclare(EXCHANGE_NAME,"direct",true,false,null);
        //创建一个持久化、非排他性、非自动删除的队列
        channel.queueDeclare(QUEUE_NAME,true,false,false,null);
        //将交换机与队列通过路由键绑定
        channel.queueBind(QUEUE_NAME,EXCHANGE_NAME,ROUTING_KEY);
        //发送一条持久化的消息 ：
        String message="你好，我是生产者，Hello world";
        channel.basicPublish(EXCHANGE_NAME,ROUTING_KEY,
                MessageProperties.PERSISTENT_TEXT_PLAIN,
                message.getBytes());
        //关闭资源

        channel.close();
        connection.close();
    }
}

 

 

二、RabbitMQ消费者代码

import com.rabbitmq.client.*;
import java.io.IOException;
import java.util.concurrent.TimeUnit;
import java.util.concurrent.TimeoutException;

/**
 * author:wupeng
 * Date:2019/2/20 11:02
 */
public class RabbitConsumer {
    private static final String QUEUE_NAME="queue_demo";
    private static final String IP_ADDRESS="localhost";
    private static final int PORT=5672;//RabbitMQ服务器的默认端口为5672

    public static void main(String[] args) throws IOException, TimeoutException, InterruptedException {
        Address[] addresses=new Address[]{
            new Address(IP_ADDRESS,PORT)
        };
        ConnectionFactory factory=new ConnectionFactory();
        factory.setUsername("root");
        factory.setPassword("root");
        Connection connection = factory.newConnection(addresses);//创建连接，此处需要IP地址集
        final Channel channel = connection.createChannel();//创建通道
        channel.basicQos(64);//设置客户端最多接收末被ack的消息个数
        DefaultConsumer consumer = new DefaultConsumer(channel) {
            @Override
            public void handleDelivery(String consumerTag, Envelope envelope, AMQP.BasicProperties properties, byte[] body) throws IOException {
                System.out.println("接收到消息： " + new String(body));
                try {
                    TimeUnit.SECONDS.sleep(1);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
                channel.basicAck(envelope.getDeliveryTag(), false);
            }
        };

        channel.basicConsume(QUEUE_NAME,consumer);
        //等待回调函数执行完毕后，关闭资源
        TimeUnit.SECONDS.sleep(5);
        Thread.sleep(5000000);
        channel.close();
        connection.close();
    }

}
