consumer启动正常，provider类的test发送消息后，consumer类就一直报这个错

我的consumer:

@Component
@Slf4j
public class OrderReceiver {

        @RabbitListener(bindings = @QueueBinding(
                value = @Queue(value = "order-queue2",durable = "true"),
                exchange=@Exchange(name = "order-exchange2",durable = "true",type = "topic"),
                key="order.*"
        ))
        @RabbitHandler
        public  void  receive(@Payload Order order, @Headers Map<String,Object> headers,
                              Channel channel)throws Exception{
            log.info("收到order消息: {}"+order);

            Long deliveryTag= (Long) headers.get(AmqpHeaders.DELIVERY_TAG);
            channel.basicAck(deliveryTag,false);//这里的false指不支持批量操作
        }
}

provider:

@Component
public class OrderSender {

    @Autowired
    private RabbitTemplate rabbitTemplate;

    public void sender(Order order) throws Exception{

        CorrelationData correlationData = new CorrelationData();
        correlationData.setId(order.getMessageId());

        rabbitTemplate.convertAndSend("order-exchange2",//exchange
                "order.abc",//routingkey
                order,                  //消息内容
                correlationData);//消息唯一id

    }

order:

@Data
public class Order implements Serializable {
    private static final long serialVersionUID = -6118152804461333255L;
    private String id;
    private String name;
    private String messageId;
}
