Question

我遇到了错误。有人可以帮我吗？我正在3个不同的线程中运行更新。大多是同一记录。但我仍然看到此错误。当我对1个线程执行相同操作时，我看不到此错误

下面是我的代码

private void createJourneyBS(Journey journey, JourneyRoute journeyRouteOld, RouteType routeType, Integer version) {

    List<RoutePointType> routePointTypes = routeType.getRoutePoint();

    for (RoutePointType routePointType : routePointTypes) {

        JourneyBSBuilder builderivs = builderHelper.getJourneyBSBuilder(routePointType);
        JourneyBS KRTT = builderivs.build();
        List<JourneyRouteTime> timeList = getJourneyRouteTime(journey, journeyRouteOld, routePointType);

        Query query = entityManager.createQuery("UPDATE JourneyBS jrp SET "
        + "jrp.type  = :type, "
        + "jrp.lastUpdatedTime = :lastUpdatedTime, "

        query.setParameter("type",  KRTT.getType());

        query.setParameter("rPN",  KRTT.getrPN());
        query.setParameter("sequenceNr", KRTT.getSequenceNr());

        int res = query.executeUpdate();

        if(res == 1){

            updateTimeList(timeList, KRTT, journey, version);
        }

        if(res == 0){

            KRTT.setJourneyRoute(journeyRouteOld);
            KRTT.setJourney(journey);
            KRTT.setVersion(version);

            genericDAO.persist(KRTT);
            createJourneyRouteTime(journey, KRTT,  routePointType, version);
        }


    }
}
