前端时间更新了mac下面安装rabbitmq 下面介绍一下使用这个mq的教程。

首先，打开mq的官网。找到Java的用例。然后试了一下，成功了。

http://www.rabbitmq.com/tutorials/tutorial-one-java.html

main方法方式用例

package org.young.common.test;

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

/**
 * Created by young on 16/10/7.
 */
public class Send {

    private final static String QUEUE_NAME = "mq.queue";

    public static void main(String[] argv) throws java.io.IOException {

        ConnectionFactory factory = new ConnectionFactory();
        factory.setHost("localhost");
//        factory.setUsername("young");
//        factory.setPassword("young");
//        factory.setVirtualHost("/");
//        factory.setPort(5672);

        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();

    }

}

package org.young.common.test;

import com.rabbitmq.client.*;

import java.io.IOException;

/**
 * Created by young on 16/10/7.
 */
public class Recv {

    private final static String QUEUE_NAME = "mq.queue";

    public static void main(String[] argv)
            throws java.io.IOException,
            java.lang.InterruptedException {

        ConnectionFactory factory = new ConnectionFactory();
        factory.setHost("localhost");
//        factory.setUsername("young");
//        factory.setPassword("young");
//        factory.setVirtualHost("/");
//        factory.setPort(5672);


        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");

        Consumer consumer = new DefaultConsumer(channel) {
            @Override
            public void handleDelivery(String consumerTag, Envelope envelope, AMQP.BasicProperties properties, byte[] body)
                    throws IOException {
                String message = new String(body, "UTF-8");
                System.out.println(" [x] Received '" + message + "'");
            }
        };
        channel.basicConsume(QUEUE_NAME, true, consumer);

    }
}

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

这样上面的步骤就完成了。后来查看一下源码发现如果你什么都不设置。源码下面是有默认设置的。
