spring rabbitmq listener方法调用不起作用

Question

我正在尝试使用基于XML而不是配置文件来实现Spring RabbitMq。消息被发送（我可以在RabbitMQ管理管理中看到它），但消费者不打印任何输出。消费者已初始化（可确认调用构造函数）。能告诉我以下问题：

rabbitConfiguration.xml ：

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

<rabbit:template id="amqpTemplate" connection-factory="connectionFactory"  exchange="my.exchange" routing-key="my.test.1" />  

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

<rabbit:queue id="myQueue" name="my.queue" />

<rabbit:topic-exchange id="myExchange" name="my.exchange">
    <rabbit:bindings>
        <rabbit:binding queue="myQueue" pattern="my.#.*">
        </rabbit:binding>
    </rabbit:bindings>
</rabbit:topic-exchange>

<rabbit:listener-container id="myListenerContainer" connection-factory="connectionFactory" >
    <rabbit:listener ref="aListener" method="printer" queues="myQueue"/>
</rabbit:listener-container>

<bean id="aListener" class="rabbitmq.MyReceiver"  />

rabbitmq.MyReceiver.java

Public class MyReceiver {

        public MyReceiver() {
        System.out.println("init..");
    }
    public void printer(String msg){
        System.out.println("message: " + msg);
    }

}

以下是不同类别中的制作人代码：

    ConfigurableApplicationContext  context = new ClassPathXmlApplicationContext("rabbitConfiguration.xml");//loading beans
    RabbitTemplate rb = (RabbitTemplate) context.getBean("amqpTemplate");
    rb.convertAndSend("blah balh");
    context.close();
