rabbitmq在c、java、python互通时的程序

java：在与python或者java语言以及C语言互通时，需要有更改，现在的程序如下：

生产者的java程序：

package RabbitMQMaven_P.test_P;

/**
* Hello world!
*
*/
import com.rabbitmq.client.Channel;
import com.rabbitmq.client.Connection;
import com.rabbitmq.client.ConnectionFactory;
public class App
{
   private final static String QUEUE_NAME = "hello";
   private final static String EXCHANGE_NAME = "hello-exchange";

    public static void main( String[] args )
    {
       ConnectionFactory cf = new ConnectionFactory();
        //rabbitmq监听IP
        cf.setHost("localhost");
        //rabbitmq默认监听端口，注意要记得开启端口
        cf.setPort(5672);

        //设置访问的用户
        cf.setUsername("admin");
        cf.setPassword("admin");
        try
        {
        //建立连接
        Connection conn = cf.newConnection();
        //创建消息通道
        Channel channel = conn.createChannel();

        String msg = "hello world!!!! 你好222~";
        //创建hello队列
        channel.queueDeclare(QUEUE_NAME, false, false, false, null);
        channel.exchangeDeclare(EXCHANGE_NAME, "direct",true);
        channel.queueBind(QUEUE_NAME, EXCHANGE_NAME, "hola");
        //发送消息
        channel.basicPublish(EXCHANGE_NAME, QUEUE_NAME, null, msg.getBytes());
        //channel.basicPublish(EXCHANGE_NAME, QUEUE_NAME, null, msg.getBytes());
        System.out.println("send msg: "+ msg + "\n to queue: ["+ QUEUE_NAME +"] !\n"+"add to exchange:["+EXCHANGE_NAME+"]!");

        channel.close();
        conn.close();
        }catch(Exception e1)
        {
           System.out.println( "try 2" );
        }
        System.out.println( "Hello World2!" );
    }

}
