Question

我有一个从guava生成listenableFutures的线程池。在任务失败时，我使用两种方法在DB中写入。

第一种方法写入包含各种信息的条目，第二种方法用条目Datetime和值更新该条目。

public void onFailure(Throwable thrown) {
        //This is the Guava callback function in case of failure
        if (retransmitPolicyFilter.isRetransmittable(thrown, event)) {
            try {
                queue.putLast(event);
                LOGGER.debug("Adding event [{}] last. It failed initially due to [{}]", event, thrown.getMessage());
            } catch (InterruptedException e) {
                LOGGER.error("Error {}", e.getMessage());
                LOGGER.debug("Error {}", e);
            }
        } else {
            try {
                EventLog eventLog = eventLoggingService.logFailedEvent(event, name, thrown);
                if (thrown instanceof ResponseTimeoutException) {
                    LOGGER.error("Error {}", thrown.getMessage());
                    LOGGER.debug("Error {}", thrown);
                    LOGGER.warn("Received a Response Timeout Exception error for event [{}] and I will not retry it", event);
                } else {
                    LOGGER.debug("Error sending event [{}]. Logging event with sid [{}]", event, eventLog.getSid(), thrown);
                    eventLog = eventLoggingService.logOutcomeForEventLog(eventLog.getSid(), "REJECTED");
                    eventService.forwardEventOutcome("REJECTED", eventLog);
                }
            } catch (Exception e) {
                LOGGER.error("Error handling failure of event [{}]. {}", event, e.getMessage());
                LOGGER.debug("{}", e);
            }
        }

执行数据库插入和更新的两种方法是：

@Override
@Transactional(propagation = Propagation.REQUIRED)
public EventLog logFailedEvent(final Event event, final String name, final Throwable thrown) {
    try {
        final EventLog om = prepareEventLog(event, name, null);
        int code = -1;
        if (thrown instanceof TimeoutResponseException) {
            code = ((NegativeResponseException) thrown).getCommandStatus();
        }

        om.setStatus(MessageDeliveryStatusEnum.FAILED.getProperty() + " " + code);

        return eventLogRepository.save(om);
    } catch (Exception e) {
        LOGGER.error("Error saving failed event [{}] for name [{}]. {}", event.toString(), name, e.getMessage());
        LOGGER.debug("{}", e);
        return null;
    }
}

@Override
@Transactional(propagation = Propagation.REQUIRED)
public EventLog logOutcomeForEventLog(final long eventId, final String outcomeValue) {
    try {
        final EventLog o = eventLogRepository.findOne(eventId);
        o.setOutcomeReceiveDate(LocalDateTime.now(Clock.systemUTC()));
        o.setOutcomeValue(outcomeValue);
        return eventLogRepository.save(o);
    } catch (Exception e) {
        LOGGER.error("Error saving outcome for id [{}] and value [{}]. {}", eventId, outcomeValue,
                e.getMessage());
        LOGGER.debug("{}", e);
        return null;
    }
}

大多数事件都失败，因此这段代码每分钟执行数千次，数据库中有数百万条记录。

上述代码生成具有outcome_receive_date和outcome_value

的数据库条目的次数为99.9％

，

除外

有时只有eventLoggingService.logFailedEvent(event,name, thrown)方法似乎正在执行

而

eventLoggingService.logOutcomeForEventLog(eventLog.getSid(), "REJECTED");未使用最后两个值（结果通知日期时间和值）更新条目。 没有记录错误，但正如您从上面所看到的，我正在为此做好准备。

我真的很茫然。

Hibarnate有时不写入db
