Java实现RabbitMQ以及Jar包的实现

今天应上级要求，撰写JAVA代码测试RabbitMQ。

以下为环境要求：

RabbitMQ环境不在此电脑，并且无法通讯，需要写完之后打成jar包，运行在另一台主机。开发工具Myeclipse10，JDK1.6,RabbitMQ3.4，所需jar包在www.rabbitmq.com上下载的rabbitmq-java-client-bin-3.6.1。

第一步，建立工程rabbitMQTest,,结构如图所示。所需Jar包放在了lib目录下，

第二步，新建class名为，Send.java,来为RabbitMQ测试发送数据。代码如下

package com.mq;


import java.util.concurrent.TimeoutException;


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


public class Send {
    private static final String TASK_QUEUE_NAME = "task_queue";


    public static void main(String[] argv) throws java.io.IOException, TimeoutException, InterruptedException {
    	    System.out.println("----------main method is begin----------");
    	    //创建工厂
        ConnectionFactory factory = new ConnectionFactory();
        System.out.println("----------factory successful!----------");
        //设置IP,端口,账户和密码
        factory.setHost("192.168.228.87");
        factory.setPort(5672);
        factory.setUsername("mq");
        factory.setPassword("mq");
        //创建连接对象
        Connection connection = factory.newConnection();
        Channel channel = connection.createChannel();
        System.out.println("----------connected successful!----------");


        // 指定队列持久化
        channel.queueDeclare(TASK_QUEUE_NAME, true, false, false, null);
        String message = getMessage(argv);
        //共发送10万条数据，每隔1S发送1次
        int index=0;
	    while (index<100000){
		Thread.sleep(1*1000);
		channel.basicPublish("", TASK_QUEUE_NAME, MessageProperties.PERSISTENT_TEXT_PLAIN, message.getBytes());
		System.out.println(" [x] Sent '" + message + "'");
		index++;
		}
        channel.close();
        connection.close();
    }




    private static String getMessage(String[] strings) {
        if (strings.length < 1)
            return "Hello World!";
        return joinStrings(strings, " ");
    }


    private static String joinStrings(String[] strings, String delimiter) {
        int length = strings.length;
        if (length == 0)
            return "";
        StringBuilder words = new StringBuilder(strings[0]);
        for (int i = 1; i < length; i++) {
            words.append(delimiter).append(strings[i]);
        }
        return words.toString();
    }
}

第三步，新建Class名为Recv.java, 来为RabbitMQ测试接收 数据。代码如下

package com.mq;
import java.io.IOException;
import java.util.concurrent.TimeoutException;

import com.rabbitmq.client.ConnectionFactory;
import com.rabbitmq.client.Connection;
import com.rabbitmq.client.Channel;
import com.rabbitmq.client.QueueingConsumer;
public class Recv {
	private static final String TASK_QUEUE_NAME = "task_queue";

    public static void recv() throws java.io.IOException, java.lang.InterruptedException, TimeoutException {
    	System.out.print("----------main method is begin----------");
        ConnectionFactory factory = new ConnectionFactory();
        System.out.println("----------factory successful!----------");
        factory.setHost("192.168.228.87");
        factory.setPort(5672);
        factory.setUsername("mq");
        factory.setPassword("mq");
        Connection connection = factory.newConnection();
        Channel channel = connection.createChannel();
        System.out.println("----------connected successful!----------");

        // 指定队列持久化
        channel.queueDeclare(TASK_QUEUE_NAME, true, false, false, null);
        System.out.println(" [*] Waiting for messages. To exit press CTRL+C");

        // 指定该线程同时只接收一条消息
        channel.basicQos(1);

        QueueingConsumer consumer = new QueueingConsumer(channel);

        // 打开消息应答机制
        channel.basicConsume(TASK_QUEUE_NAME, false, consumer);

        while (true) {
            QueueingConsumer.Delivery delivery = consumer.nextDelivery();
            String message = new String(delivery.getBody());

            System.out.println(" [x] Received '" + message + "'");
            doWork(message);
            System.out.println(" [x] Done");

            // 返回接收到消息的确认信息
            channel.basicAck(delivery.getEnvelope().getDeliveryTag(), false);
        }
    }

    private static void doWork(String task) throws InterruptedException {
        for (char ch : task.toCharArray()) {
            if (ch == '.')
                Thread.sleep(1000);
        }
    }
    public static void main(String[] args) throws IOException, InterruptedException, TimeoutException {
    	recv();
	}
}

最后，打成Jar包，分别为Send.jar和Recv.jar,在下图2的第1步中Send.jar要选Send的main方法，Recv.jar要选Recv的main方法，这里只对Sen.jar贴图：

打好的包，即可在另一台装有rabbitMQ环境和JRE环境中运行，具体使用的命令是：
