java操作rabbitmq实现简单的消息发送（socket编程的升级）

准备：

　　1.下载rabbitmq并搭建环境(和python那篇一样:http://www.cnblogs.com/g177w/p/8176797.html)

　　2.下载支持的jar包(http://repo1.maven.org/maven2/com/rabbitmq/amqp-client)

生产者方(Productor.java)：

 package RabbitMQTest;

 import java.util.HashMap;
 import java.util.Map;

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

 public class Productor {
 public static String QUEUE_NAME = "STEVEN";
 public static void main(String[] args) {
     //初始化socket链接
     ConnectionFactory factory = new ConnectionFactory();
     //指定链接地址
     factory.setHost("localhost");
     try{
     //建立程序和rabbitmq的socket连接
     Connection connection = factory.newConnection();
     //创建管道
     Channel channel = connection.createChannel();
     //声明队列
     channel.queueDeclare(QUEUE_NAME,false,false,false,null);
     //让当前线程睡眠8s，以检验rabbitmq的消息轮询
     Thread.currentThread().sleep(8000);
     String message = "hello,world";
     //发送消息
     channel.basicPublish("", QUEUE_NAME, null, message.getBytes());
     System.out.println("[x] send the message"+message);
     channel.close();
     connection.close();
     }catch (Exception e) {
         System.out.println("程序出错:"+e);
     }

 }
 }

消费者方(Consummer.java):

 package RabbitMQTest;
 import com.rabbitmq.client.Connection;
 import com.rabbitmq.client.Channel;
 import com.rabbitmq.client.ConnectionFactory;
 import com.rabbitmq.client.QueueingConsumer;
 import com.rabbitmq.client.QueueingConsumer.Delivery;
 /**

 public class Consumer {
     public static void main(String[] args) {
         try {
             //创建连接工厂对象
             ConnectionFactory factory = new ConnectionFactory();
             //设置工厂对象的参数，用来连接rabbitmq
             factory.setHost("localhost");
             //建立程序与rabbitmq的socket连接
             Connection connection = factory.newConnection();
             //创建管道
             Channel channel = connection.createChannel();
             //声明队列
             channel.queueDeclare(Productor.QUEUE_NAME, false, false, false, null);
             System.out.println(" [*] Waiting for messages. To exit press CTRL+C");
             //创建队列消费对象
             QueueingConsumer consumer = new QueueingConsumer(channel);
             //设置参数
             channel.basicConsume(Productor.QUEUE_NAME, true, consumer);
             //创建接收对象来接收来自服务端的消息
             Delivery delivery = null;
             //循环接收，相当于开启了一个监听
             while (true) {
                 delivery = consumer.nextDelivery();
                 String message = new String(delivery.getBody());
                 System.out.println(" [x] Received '" + message + "'");
             }
         } catch (Exception e) {
             System.out.println(e);
         }
     }
 }
