RabbitMQ遵循的是AMQP协议,许可证the Mozilla Public License v1.1和 the GNU General Public License  v2. 

RabbitMQ由ERLANG实现的,需要ERLANG VM才能运行

首先安装Erlang,下载http://www.erlang.org/download/otp_win32_R16B02.exe,设置环境变量

安装RabbitMQ Server,下载rabbitmq-server-windows-3.2.1.zip直接解压到目录即可,rabbitmq_server-3.2.1\sbin目录是rabbitserver的执行命令目录

rabbitmq-server.bat start broke as an application.

rabbitmq-service.bat manages the service and starts the broker.

rabbitmqctl.bat manages a running broker.

下载安装RabbitMQ Client,下载Client Library,http://www.rabbitmq.com/releases/rabbitmq-java-client/v3.2.1/rabbitmq-java-client-bin-3.2.1.zip,解压到目录。

利用Client Library编写HelloWord示例,Product发送HelloWord到Queue,consume从Queue中收取消息

消息生产者Send

package com.prometon.yang.rabbitmq;

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

public class Send {
        
  private final static String QUEUE_NAME = "hello";

  public static void main(String[] argv) throws Exception {
              
    ConnectionFactory factory = new ConnectionFactory();
    factory.setHost("localhost");
    Connection connection = factory.newConnection();
    Channel channel = connection.createChannel();

    channel.queueDeclare(QUEUE_NAME, false, false, false, null);
    String message = "Hello World!";
    channel.basicPublish("", QUEUE_NAME, null, message.getBytes());
    System.out.println(" [x] Sent '" + message + "'");
    
    channel.close();
    connection.close();
  }
}

消息消费者Recv

package com.prometon.yang.rabbitmq;

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

public class Recv {
        
    private final static String QUEUE_NAME = "hello";

    public static void main(String[] argv) throws Exception {

    ConnectionFactory factory = new ConnectionFactory();
    factory.setHost("localhost");
    Connection connection = factory.newConnection();
    Channel channel = connection.createChannel();

    channel.queueDeclare(QUEUE_NAME, false, false, false, null);
    System.out.println(" [*] Waiting for messages. To exit press CTRL+C");
    
    QueueingConsumer consumer = new QueueingConsumer(channel);
    channel.basicConsume(QUEUE_NAME, true, consumer);
    
    while (true) {
      QueueingConsumer.Delivery delivery = consumer.nextDelivery();
      String message = new String(delivery.getBody());
      System.out.println(" [x] Received '" + message + "'");
    }
  }
}

执行程序:

 [x] Sent 'Hello World!'

 [*] Waiting for messages. To exit press CTRL+C
 [x] Received 'Hello World!'
