RabbitMQ SpringAMQP xml配置

我正在尝试使用RabbitMQ的小应用程序,其中我的发送器是用Spring AMQP xml配置编写的,接收器是用python用PIKA编写的。  如果我的方法是正确的,请告诉我。

这是我的发件人文件 -

import org.springframework.amqp.core.AmqpTemplate;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class SpringAMQPRabbitSender {
    private final static String SENDER_XML = "springamqp-rabbit-sender-context.xml";
    public static void main(String[] args) throws Exception {
      AmqpTemplate amqpTemplate = (AmqpTemplate)(new ClassPathXmlApplicationContext(SENDER_XML)).getBean("amqpTemplate");
      int messagCount = 0;
      while (messagCount < 10){
        amqpTemplate.convertAndSend("tp.routingkey.1", "Message # " + messagCount++);
      }
      System.out.println( messagCount + " message(s) sent successfully.");
    }
}

这是我的springamqp-rabbit-sender-context.xml文件

<?xml version="1.0" encoding="utf-8" ?>
<beans xmlns="http://www.springframework.org/schema/beans"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xmlns:rabbit="http://www.springframework.org/schema/rabbit"
  xsi:schemaLocation="http://www.springframework.org/schema/beans 
  http://www.springframework.org/schema/beans/spring-beans-3.1.xsd 
  http://www.springframework.org/schema/rabbit 
  http://www.springframework.org/schema/rabbit/spring-rabbit-1.0.xsd">

<rabbit:connection-factory id="connectionFactory" 
host="localhost" username="guest" password="guest"/>

<rabbit:admin connection-factory="connectionFactory"/>

<rabbit:template id="amqpTemplate" connection-factory="connectionFactory"
exchange="tpExchange"/> 
</beans>

现在这是我的python接收器 -

#!/usr/bin/env python
import pika
import sys

connection = pika.BlockingConnection(pika.ConnectionParamet(host='localhost'))
channel = connection.channel()

channel.exchange_declare(exchange='tpExchange',
                     exchange_type='topic')

channel.queue_declare(queue = "tpQueue")

key = "tp.routingkey.1"
channel.queue_bind(exchange='tpExchange',
                   queue="tpQueue",
                   routing_key="tp.routingkey.1")

print(' [*] Waiting for logs. To exit press CTRL+C')

def callback(ch, method, properties, body):
    print(" [x] %r:%r" % (key, body))

channel.basic_consume(callback,
                  queue="tpQueue",
                  no_ack=True)

channel.start_consuming()

这是对的吗?我错过了什么吗?请建议。

提前致谢。

但是,在几个例子中,我看到在发送方也配置了队列交换绑定。所以我想澄清一下。

不,你绝对不需要在发送方这样做。只需知道exchangerouting key即可。队列及其绑定甚至不是接收器的问题,但我们通常在那里绑定。

当然,正常的方法是经纪人配置。
