本文详细介绍了如何使用RabbitMQ的Java客户端库实现消息发送与接收的功能，包括创建连接、建立通道、定义队列、发送与接收消息等关键步骤。通过示例代码展示了从发送端到接收端的完整流程，并提供了运行10000次发送接收消息的主类。

1.下载rabbitmq的javaClient库

文件名：rabbitmq-client.jar

下载地址：http://download.youkuaiyun.com/detail/monkey131499/9440572

下载后将文件导入到项目中。

2.消息发送类

import java.io.IOException;
import java.util.concurrent.TimeoutException;
import org.apache.log4j.Logger;
import com.rabbitmq.client.Channel;
import com.rabbitmq.client.Connection;
import com.rabbitmq.client.ConnectionFactory;

/** 
 * send message
 * @author monkey 
 * 
 */ 

public class Send {//发送端
     private final static String QUEUE_NAME = "queue_test_1";  
     static Logger logger = Logger.getLogger(Send.class);
      
        public static void start() throws IOException, TimeoutException  
        {  
            //connection制造工厂
            ConnectionFactory factory = new ConnectionFactory();  
            //由于rabbitmq-server安装在本机，故用localhost或127.0.0.1
            factory.setHost("localhost");  
            //创建连接
            Connection connection = factory.newConnection();  
            //创建渠道
            Channel channel = connection.createChannel();  
            //定义queue属性
            channel.queueDeclare(QUEUE_NAME, false, false, false, null);  
            
            String message = "This is the test message~";  
            //发送消息  
            channel.basicPublish("", QUEUE_NAME, null, message.getBytes());  
          
            logger.info(" [*] Send '" + message + "' to "+QUEUE_NAME+" success!" );
      
            channel.close();  
            connection.close();  
        }  
}

3.消息接收类

import org.apache.log4j.Logger;
import com.rabbitmq.client.Channel;
import com.rabbitmq.client.Connection;
import com.rabbitmq.client.ConnectionFactory;
import com.rabbitmq.client.GetResponse;

/** 
 * receive message
 * @author monkey 
 * 
 */ 

public class Receive {//接收端
	//定义queue名称
	 private final static String QUEUE_NAME = "queue_test_1";  
	 //设置日志
	 static Logger logger = Logger.getLogger(Receive.class);
	  
	    public static void start() throws Exception  
	    { 
	    	//connection制造工厂
	        ConnectionFactory factory = new ConnectionFactory();  
	        //由于rabbitmq-server安装在本机，故用localhost或127.0.0.1
	        factory.setHost("localhost");  
	        //创建连接
	        Connection connection = factory.newConnection();  
	        //创建渠道
	        Channel channel = connection.createChannel();  
	        //定义queue属性
	        channel.queueDeclare(QUEUE_NAME, false, false, false, null);  
	       // logger.info("[*] Waiting for messages. To exit press CTRL+C");
	       
	        boolean noAck = false;  
            GetResponse response = channel.basicGet(QUEUE_NAME, noAck);  
            if (response == null) {  
            	logger.info("[*] Waiting for messages. To exit press CTRL+C"); 
            } else {  
                byte[] body = response.getBody();  
                long deliveryTag = response.getEnvelope().getDeliveryTag();  
                String message = new String(body);  
                logger.info("[**] Received '" + message + "' from "+QUEUE_NAME); 
                channel.basicAck(deliveryTag, false); // acknowledge receipt of the message  
            }  
            channel.close();  
            connection.close();  
	    }  
}

4.主类（运行10000次发送接收消息）

/** 
 * main
 * @author monkey 
 * 
 */ 

public class Main {
	public static void main(String[] args) throws Exception {
		int num=10000;
		int i=0;
		while(i<num){
			Send.start();
			Receive.start();
			i++;
		}
	}
}
