@Component
@ConditionalOnProperty(name = "spring.rabbitmq.enable", havingValue = "true", matchIfMissing = true)
public class MultiExchangeMessageListener{
    private static final Logger logger = LoggerFactory.getLogger(MultiExchangeMessageListener.class);

    @Autowired
    private IdempotentMessageProcessor idempotentProcessor;

    @Autowired
    private RabbitTemplate rabbitTemplate;

    /**
     * 监听来自多个交换机的消息
     */

    // 声明 Direct 交换机、队列，并绑定路由键
    @RabbitListener(bindings = @QueueBinding(
            value = @Queue(name = "order.queue", durable = "true"),    // 队列
            exchange = @Exchange(name = "20250917test1", type = ExchangeTypes.FANOUT) // 交换机
    ))
    public void handleMessage(Message message) throws IOException {
        String messageId = message.getMessageProperties().getMessageId();
        String exchange = message.getMessageProperties().getReceivedExchange();
        long deliveryTag = message.getMessageProperties().getDeliveryTag();
        }

配置文件：在yml里配置具体开关的属性,配置rabbitMq启用开关,false为关闭，true为启用.
