Spring AMQP：希望将消息放入队列并立即发送ACK

Question

public class MyAmqpConfiguration {

    @Autowired
    ConnectionFactory connectionFactory;

    @Bean
    public SimpleMessageListenerContainer messageListenerContainer() {

    SimpleMessageListenerContainer container = new SimpleMessageListenerContainer(connectionFactory);
    container.setQueues(activityLogsQueue());
    container.setMessageListener(MyMessageListener());
            container.setConcurrentConsumers(3);

    return container;
    }

        @Bean(name="myTemplate")
        public RabbitTemplate rabbitTemplate() {
        RabbitTemplate template = new RabbitTemplate(connectionFactory);
        template.setMessageConverter(MyMessageConverter());
        return template;
        }
}


public class MyMessageListener implements MessageListener {


   public MyMessageListener(MessageConverter converter, MyMessageHandler<MyObject> messageHandler) {
      this.converter = converter;
      this.messageHandler = messageHandler;
    }

   @Override
   public void onMessage(Message message) {
     this.messageHandler.doThings();
   }

}

public class MyMessageHandler  {

     @Autowired
     @Qualifier("myTemplate")
     RabbitTemplate template;

     @Override
     public void handleMessage(MyObject thing) {
         template.convertAndSend(exchange, routingKey, thing);
     }

}


public class MyMessageConverter extends JsonMessageConverter {

    @Override
     protected Message createMessage(Object object, MessageProperties messageProperties) { 
        //do things
     }

     @Override
     public Object fromMessage(Message message) throws MessageConversionException {
         throw new UnsupportedOperationException("fromMessage is not supported in "+this.getClass().getName());
     }


}

如果您不想必须对每个消息进行访问，那么可以通过以下操作在SimpleMessageListenerContainer上设置AccountygeMode

container.setAcknowledgeMode(AcknowledgeMode.NONE);

查看API参考以获得更多信息。

更新：应该是确认的mode.none
