资源(Windows):

  下载Erlang,地址:http://www.erlang.org/download/otp_win32_R15B.exe ,双击安装即可(首先装)

  下载RabbitMQ,地址:http://www.rabbitmq.com/releases/rabbitmq-server/v3.3.4/rabbitmq-server-3.3.4.exe ,双击安装即可

  下载rabbit-client.jar ,Java代码时需要导入。地址:http://www.rabbitmq.com/releases/rabbitmq-java-client/v3.3.4/rabbitmq-java-client-bin-3.3.4.zip

启动:

  安装完成后,在RabbitMQ的安装目录的sbin会有:rabbitmq-server.bat

  在cmd下:进入sbin目录,运行rabbitmq-server start

Java应用:

  Send.java

package cc.demo.rabbitmq;

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

public class Send
{
    //队列名称
    private final static String QUEUE_NAME = "hello";

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

  Recv.java

package cc.demo.rabbitmq;

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
    private 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");
        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 + "‘");
        }

    }
}
