Question

我有一个像这样的简单路线

    from("file:data/inbox?noop=true").transform().body().to("file:data/outbox").bean(UpdateInventory.class);
            from("direct:update").to("file:data/anotherbox").to("direct:newupdate");
            from("direct:newupdate").to("file:data/newbox");

我期待的输出是

   -file://data/inbox
  --transform[simple{body}]        15 ms
  --file:data/outbox                5
  ---bean[com.classico.sample.UpdateInventory@3a469fea   19
  ---file:data/anotherbox                                6
  ----direct:newupdate                                   5
  -----file:data/newbox                                    4

我尝试使用EventNotifier，当收到ExchangeCompletedEvent时，我获取了消息History.But，因为第二次交换完成后，第一个消息历史以调用的相反顺序显示。是否可以存储所有的messgae历史记录一个集合并以相反的顺序打印它们还是有任何适合的事件。？

 if (event instanceof ExchangeCompletedEvent) { 
                    ExchangeCompletedEvent exchangeCompletedEvent = (ExchangeCompletedEvent) event; 
                    Exchange exchange = exchangeCompletedEvent.getExchange(); 
                    String routeId = exchange.getFromRouteId(); 
                    List<MessageHistory> list = exchange.getProperty(Exchange.MESSAGE_HISTORY, List.class); 

                    for (MessageHistory history : list) { 
                            String id = history.getNode().getId(); 
                            String label = URISupport.sanitizeUri(history.getNode().getLabel()); 

                            log.info(String.format(MESSAGE_HISTORY_OUTPUT, routeId, id, label, history.getElapsed())); 
                    }
}
