Question

这是我的代码：

package pushnotiruntest;

import com.rabbitmq.client.BuiltinExchangeType;
import com.rabbitmq.client.Channel;
import com.rabbitmq.client.Connection;
import com.rabbitmq.client.ConnectionFactory;
import java.io.IOException;

import java.util.logging.Logger;

public class Send extends Thread {

   String name = "";
   String app_type = "";
   private static final String EXCHANGE_NAME = "topic_exchange";

    public void run()
    {
        ConnectionFactory connFac = new ConnectionFactory();
        connFac.setHost("localhost");

        try {

                Connection conn = connFac.newConnection();
                Channel channel = conn.createChannel();
                channel.exchangeDeclare(EXCHANGE_NAME, BuiltinExchangeType.TOPIC);
                for(int j=1; j<=20000; j++)
                {
                    //randomWait();

                    String routingKey = j+"."+"update"+"."+app_type;
                    String msg = name;
                    channel.basicPublish(EXCHANGE_NAME, routingKey, null, msg.getBytes("UTF-8"));
                    System.out.println("Sent " + routingKey + " : " + msg + "");
                }

                channel.close();
                conn.close();

        } catch (IOException ex) {
            Logger.getLogger(Send.class.getName()).log(Level.SEVERE, null, ex);
            System.out.println("Exception1 :--"+ex);

        } catch (TimeoutException ex) {
            Logger.getLogger(Send.class.getName()).log(Level.SEVERE, null, ex);
            System.out.println("Exception 2:--"+ex);
        }
    }

    /*void randomWait()
    {
        try {
           Thread.currentThread().sleep((long)(3*Math.random()));
        } catch (InterruptedException x) {
           System.out.println("Interrupted!");
        }
    }*/

   public static void main(String[] args) {
        // TODO code application logic here

        Send test1 = new Send();
        test1.name = "Hello ANDROID";
        test1.app_type = "ANDROID";
        Send test2 = new Send();
        test2.name = "Hello IOS";
        test2.app_type = "IOS";
        Send test3 = new Send();
        test3.name = "Hello WINDOWS";
        test3.app_type = "WINDOWS";

        test1.start();
        test2.start();        
        test3.start();
    }

我正在用Java编写代码（使用的消息代理是RabbitMQ），我希望将生成器发送的消息存储在具有不同路由密钥的单个队列中。

根据不同消费者的模式获取消息与路由密钥模式匹配。（我正在使用Topic交换进行模式匹配）。

如何在RabbitMQ中使用不同的路由键将多条消息发布到单个队列？
