Question

我有一个企业事件驱动的应用程序。我有16个MDB从JMS队列中读取。当我得到一些不受控制的异常时，我收到了这个堆栈：

在此之后，所有MDB都停止从队列中读取，并且需要重新启动应用程序。

这是MDB onMessage代码：

@Override
    @TransactionAttribute(TransactionAttributeType.REQUIRED)
    public void onMessage(Message message) {
        OnlineEventMessage<? extends Serializable> eventMessage = null;
        try {
            TextMessage textMessage = (TextMessage) message;
            String stringMessage = textMessage.getText();

            logger.debug("e' stato ricevuto il messaggio {}", stringMessage);
            logger.debug("eventMessageParser {}", onlineEventMessageParser);
            logger.debug("legacyEventMessageService {}", legacyEventMessageService);

            EventMessageAnagrafica anagrafica = anagraficaParser.parse(stringMessage, true);
            String multichannelId = anagrafica.getMultichannelId();

            eventMessage = onlineEventMessageParser.parse(stringMessage, true);

            MDC.put("multichannelId", multichannelId);
            MDC.put("eventType", eventMessage.getEventType().getEventCode());
            legacyEventMessageService.handle(eventMessage);
        } catch (JMSException e) {
            retryJmsTemplate.send(destination, new RedeliveryMessageCreatorUtil(message));
            logger.error("si e' verificato un errore JMS nel processamento dell'evento {}, riaccodamento in corso...", e);
        } catch (RuntimeException e) {
            logger.error("si e' verificata una runtime exception per il messaggio {}", e);

            legacyErrorHandlerService.handle(eventMessage);

        } catch (Exception e) {
            logger.error("si e' verificato un errore inaspettato per il messaggio {}", e);
            if (eventMessage != null && eventMessage.getIdEventMessage() != null) {
                logger.error("Il messaggio gia' presente nelle catene di elaborazione");
                OnlineEventMessage<?> onlineMessage = eventMessageDao.getItemByID(eventMessage.getIdEventMessage());
                if (onlineMessage != null) {
                    onlineMessage.setEventState(EventState.PROCESSING_ERROR);
                    eventMessageDao.updateItem(onlineMessage);
                    eventMessageDao.flush();
                }
            }
            context.setRollbackOnly();
        }
    }

有什么想法吗？亲切的问候马西莫

这似乎是一个交易问题。下次发生这种情况时尝试进行线程转储，并查看线程正在做什么。您可以通过管理控制台执行此操作。

此异常后，MDB停止工作
