@Validated
@Component
public class ConsumeBarcodes
{
  private static final Logger logger = LoggerFactory.getLogger(ConsumeBarcodes.class);

  @Value("${rabbitmq.queue}")
  private String queueName;

  public ConsumeBarcodes() {}

  @RabbitListener(queues = "${rabbitmq.queue}", ackMode = "AUTO")
  public void ingestNewBarcodes(@NotNull NewBarcodes newBarcodes)
  {
    logger.debug("RECEIVED message in ingestNewBarcodes from RabbitMQ queue: {}", queueName);
    // XXX Process newBarcodes here.
  }
}

建议：

package com.acme.interceptors;

...

public class TrackNewBarcode implements MethodInterceptor
{
  ...
  @Override
  public Object invoke(MethodInvocation methodInvocation) throws Throwable
  {
    NewBarcodes newBarcodes = (NewBarcodes)methodInvocation.getArguments()[1];
    ...
  }
}

在我看到的@RabbitListener通知的示例中，在invoke()中，参数#1被强制转换为Message，但在我的@RabbitListener中，我依赖于Jackson消息转换器将入站参数转换为POJO NewBarcodes。
问题：在我的建议中，我可以将参数#1转换为POJO NewBarcodes吗？
