rabbitMQ学习(一)

一般模式

服务端:

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

public class Recv {
	
	//队列名称  
    public final static String QUEUE_NAME = "hello";  
  
    public static void main(String[] argv) throws java.io.IOException,  
            java.lang.InterruptedException  
    {  
        //打开连接和创建频道,与发送端一样  
        ConnectionFactory factory = new ConnectionFactory();  
        factory.setHost("localhost");
        factory.setPort(5672);
        factory.setUsername("test");
        factory.setPassword("test");
        Connection connection = factory.newConnection();  
        Channel channel = connection.createChannel();  
        //声明队列,主要为了防止消息接收者先运行此程序,队列还不存在时创建队列。  
        channel.queueDeclare(QUEUE_NAME, false, false, false, null);  
        System.out.println(" [*] Waiting for messages. To exit press CTRL+C");  
          
        //创建队列消费者  
        QueueingConsumer consumer = new QueueingConsumer(channel);  
        //指定消费队列  
        channel.basicConsume(QUEUE_NAME, true, consumer);  
        while (true)  
        {  
            //nextDelivery是一个阻塞方法(内部实现其实是阻塞队列的take方法)  
            QueueingConsumer.Delivery delivery = consumer.nextDelivery();  
            String message = new String(delivery.getBody());  
            System.out.println(" [x] Received '" + message + "'");  
        }  
  
    }  

}

  发送

import java.util.Map;

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

public class Send {
	//队列名称  
   // private final static String QUEUE_NAME = "dear";  
  
    public static void main(String[] argv) throws java.io.IOException  
    {  
        /** 
         * 创建连接连接到MabbitMQ 
         */  
        ConnectionFactory factory = new ConnectionFactory();  
        //设置MabbitMQ所在主机ip或者主机名  
        factory.setHost("localhost");  
        //创建一个连接  
        Connection connection = factory.newConnection();  
        //创建一个频道  
        Channel channel = connection.createChannel();  
        //指定一个队列  
        /**
         * Recv.QUEUE_NAME 队列名
         * durable 持久化(把数据写到磁盘上,当服务器重启后数据还在)
         * exclusive 占用链接(该队列是否时独占的即连接上来时它占用整个网络连接)
         * autoDelete 自动删除(当前队列没有连接时,自动删除。即没有消费者对接上来时自动删除)
         * arguments 其他参数如TTL(队列存活时间)等
         */
        Map<String, Object> arguments=null;
        channel.queueDeclare(Recv.QUEUE_NAME, false, false, false, arguments);  

        //发送的消息  
        String message = "hello "+Recv.QUEUE_NAME+"!";  
        //往队列中发出一条消息  
        channel.basicPublish("", Recv.QUEUE_NAME, MessageProperties.PERSISTENT_TEXT_PLAIN, message.getBytes());  
        System.out.println(" [x] Sent '" + message + "'");  
        //关闭频道和连接  
        channel.close();  
        connection.close();  
     }
