mac下使用RabbitMQ(Java语言)

Posted 2020-06-13

操作系统为OS X Yosemite 10.10.3

?

1.下载安装

在官网http://www.rabbitmq.com/download.html下载RabbitMQ Server,这个页面右侧有导航，可以找到Install: Mac OS X链接，或者页面中的Installation Guides项目下可以找到Mac OS X:?Standalone下载地址,现在最新版本为rabbitmq-server-mac-standalone-3.6.0.tar.xz，下载解压这个文件。

?

2.启动服务器

终端进入解压之后的目录

cd rabbitmq_server-3.6.0

cd sbin

sudo sh rabbitmq-server

终端输出：

RabbitMQ 3.6.0. Copyright (C) 2007-2015 Pivotal Software, Inc.
## ## Licensed under the MPL. See http://www.rabbitmq.com/
## ##
########## Logs: /Users/zhangmeng27/Downloads/proj/RabbitMQ/rabbitmq_server-3.6.0/var/log/rabbitmq/[email protected]
###### ## /Users/zhangmeng27/Downloads/proj/RabbitMQ/rabbitmq_server-3.6.0/var/log/rabbitmq/[email protected]
##########
Starting broker... completed with 0 plugins.

表明RabbitMQ 服务器已经启动

3.查询服务器状态，关闭服务器

另启一个终端，进入rabbitmq_server-3.6.0/sbin目录下，可以通过?sh rabbitmqctl status 命令查看已经启动的服务器的状态，rabbitmqcrl相关的命令解释可以在这里找到

关闭RabbitMQ服务器可以在启动服务器的那个终端中通过control+c关闭服务，或者新启一个终端进入sbin目录，通过?sh rabbitmqctl stop?命令关闭服务器。

4.通过web管理和监控RabbitMQ

rabbitmqctl组合对应命令可以通过终端查看rabbitmq服务器的状态，但是这样很不直观，rabbitmq还提供了web页面查看并管理rabbitmq服务器，这个功能通过插件实现，默认插件没有开启，所以上面启动服务器过程中最后提示completed with 0 plugins。启动rabbitmq服务器的状态下，另起一个终端在sbin下执行?sh rabbitmq-plugins enable rabbitmq_management?会提示

The following plugins have been enabled:
mochiweb
webmachine
rabbitmq_web_dispatch
amqp_client
rabbitmq_management_agent
rabbitmq_management

Applying plugin configuration to [email protected] started 6 plugins.

现在可以通http://localhost:15672打开web页面

使用默认的账号密码guest/guest登录,登录之后可以看到rabbitmq服务器的内部状态，队列中的消息收发数目，连接数量，状态等信息?

5.java代码实现Producer和Consumer

创建一个maven项目，pom.xml中添加rabbitmq依赖，并使用assembly插件进行打包，因为最终需要同时启动Producer和Consumer两个客户端，所以打包方便后面的实验。

打包配置中是把消费者MQConsumer作为main类的，因此之后生成的jar包启动的是消费者。

pom.xml配置如下?

?消费者代码如下

package test.rabbitmq;

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

import java.io.IOException;

/**
 * Created by zhangmeng27 on 16/2/1.
 */
public class MQConsumer {

	private final static String QUEUE_NAME = "hello";

	public static void recv(){
		ConnectionFactory factory = new ConnectionFactory();
		factory.setHost("localhost");
		try {
			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 + "‘");
			}

		} catch (IOException e) {
			e.printStackTrace();
		} catch (InterruptedException e) {
			e.printStackTrace();
		}
	}

	public static void main(String[] args) {
		recv();
	}
}

?消息的生产者的代码 ?

package test.rabbitmq;

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

import java.io.IOException;
import java.util.Scanner;

/**
 * Created by zhangmeng27 on 16/2/1.
 */
public class MQProducer {

    private static final String QUEUE_NAME = "hello";

    public void start(){
        ConnectionFactory factory = new ConnectionFactory();
        factory.setHost("localhost");
        Connection connection = null;
        Channel channel = null;
        Scanner sc = new Scanner(System.in);
        try {
            connection = factory.newConnection();
            channel = connection.createChannel();
            channel.queueDeclare(QUEUE_NAME, false, false, false, null);

            String message = "hello world,try again";
            System.err.println("-----输入字符串，回车进行发送,\"quit\"退出------");
            while(sc.hasNext()){
                message = sc.nextLine();
                channel.basicPublish("", QUEUE_NAME, null, message.getBytes());
                System.out.println(" [x] Sent ‘" + message + "‘");
                if(message.equals("quit")){
                    message = "Producer已经退出！！";
                    System.out.println(" [x] Sent ‘" + message + "‘");
                    channel.basicPublish("", QUEUE_NAME, null, message.getBytes());
                    break;
                }
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
        finally {
            try {
                channel.close();
                connection.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }

    public static void main(String[] args) {
        MQProducer p = new MQProducer();
        p.start();
    }

}

IntelliJ IDEA中make之后会在target下生成rabbitmq-1.0-SNAPSHOT-jar-with-dependencies.jar文件，启动RabbitMQ服务器，终端进入刚才生成jar包所在目录，通过java -jar?rabbitmq-1.0-SNAPSHOT-jar-with-dependencies.jar启动消费者

在IntelliJ IDEA中启动MQProducer这个类，控制台中输入字符串回车即可发送。下图左边为启动的消费者终端，右边为IntelliJ IDEA中控制台
