Java创建consumer对象，回调onRefreshMsg方法，数据如何落地

这里操作onRefreshMsg回调方法不能注入，使用@Autowired后此接口不会被回调

class AppClient implements OmmConsumerClient
{
  
   public void onRefreshMsg(RefreshMsg refreshMsg, OmmConsumerEvent event)
   {
  
      System.out.println(refreshMsg);
   }
   
   public void onUpdateMsg(UpdateMsg updateMsg, OmmConsumerEvent event) 
   {
  
      System.out.println(updateMsg);
   }

   public void onStatusMsg(StatusMsg statusMsg, OmmConsumerEvent event) 
   {
  
      System.out.println(statusMsg);
   }

   public void onGenericMsg(GenericMsg genericMsg, OmmConsumerEvent consumerEvent){}
   public void onAckMsg(AckMsg ackMsg, OmmConsumerEvent consumerEvent){}
   public void onAllMsg(Msg msg, OmmConsumerEvent consumerEvent){}
}

OmmConsumer consumer = null;
try
{
   AppClient appClient = new AppClient();
   
   OmmConsumerConfig config = EmaFactory.createOmmConsumerConfig();
   
   consumer  = EmaFactory.createOmmConsumer(config.host("localhost:14002").username("user"));
   
   ReqMsg reqMsg = EmaFactory.createReqMsg();
   
   consumer.registerClient(reqMsg.serviceName("DIRECT_FEED").name("IBM.N"), appClient);
   
   Thread.sleep(60000);         // API calls onRefreshMsg(), onUpdateMsg() and onStatusMsg()
} 
catch (InterruptedException | OmmException excp)
{
   System.out.println(excp.getMessage());
}
finally 
{
   if (consumer != null) consumer.uninitialize();
}
