java访问rabbitMQ队列教程二，该节主要讲解利用Java来获取在rabbitMQ中的消息对象。

发送消息的代码如下：

代码

/** *  */package com.rabbitMQ.pro; import com.rabbitmq.client.ConnectionFactory;import com.rabbitmq.client.Connection;import com.rabbitmq.client.Channel; /** * @filename Send.java * @author code by jianghuiwen * @mail [e-mail] * * 上午8:57:08 */public class Send {   private final static String QUEUE_NAME = "hello";   public static void main(String[] argv)          throws java.io.IOException {       /*使用工厂类建立Connection和Channel，并且设置参数*/      ConnectionFactory factory = new ConnectionFactory();        factory.setHost("192.168.10.86");//MQ的IP          factory.setPort(5672);//MQ端口          factory.setUsername("hfc");//MQ用户名          factory.setPassword("hfc");//MQ密码        Connection connection = factory.newConnection();        Channel channel = connection.createChannel();          /*创建消息队列，并且发送消息*/        channel.queueDeclare(QUEUE_NAME, false, false, false, null);        for(int i=0;i<5;i++)        {        String message = String.valueOf(i);          channel.basicPublish("", QUEUE_NAME, null, message.getBytes());          System.out.println(" [x] Sent '" + message + "'");        }          /*关闭连接*/        channel.close();        connection.close();      } }

接收代码如下：

代码

/** *  */package com.rabbitMQ.pro; import com.rabbitmq.client.ConnectionFactory;import com.rabbitmq.client.Connection;import com.rabbitmq.client.Channel;import com.rabbitmq.client.QueueingConsumer; /** * @filename Recv.java * @author code by jianghuiwen * @mail [e-mail] * * 上午9:17:52 */public class Recv {   private final static String QUEUE_NAME = "hello";     public static void main(String[] argv)        throws java.io.IOException,               java.lang.InterruptedException {      /*建立连接*/      ConnectionFactory factory = new ConnectionFactory();      factory.setHost("192.168.10.86");//MQ的IP        factory.setPort(5672);//MQ端口        factory.setUsername("hfc");//MQ用户名        factory.setPassword("hfc");//MQ密码      Connection connection = factory.newConnection();      Channel channel = connection.createChannel();       /*声明要连接的队列*/      channel.queueDeclare(QUEUE_NAME, false, false, false, null);      System.out.println(" [*] Waiting for messages. To exit press CTRL+C");       /*创建消费者对象，用于读取消息*/      QueueingConsumer consumer = new QueueingConsumer(channel);      channel.basicConsume(QUEUE_NAME, true, consumer);      /* 读取队列，并且阻塞，即在读到消息之前在这里阻塞，直到等到消息，完成消息的阅读后，继续阻塞循环*/      while (true) {        QueueingConsumer.Delivery delivery = consumer.nextDelivery();        String message = new String(delivery.getBody());        System.out.println(" [x] Received '" + message + "'");      }      }}

输出结果：

其中四个数字是已经发送到消息队列的消息，我们可以看到，已经能够成功的获取数据。
