Question

当我在带有SQL Server的Java中运行以下代码时，出现超时异常。它适合1个用户，但是当我同时测试多个并发用户（仅10个）时，会出现超时错误。请帮忙。

public void deleteAgmtWrkldDetail(Integer agreementId, Integer groupId, List<String> months, Integer staffId, String tempId, int userId,  String agmtNo, String staffCatCode,
        List<BigDecimal> workLoadList, AgmtWorkloadSummary wSummary) {

    Integer manSchId = insertOrUpdateManningSchedule(agreementId, groupId, staffId, tempId, userId, agmtNo);
    if(months != null && months.size() > 0) {           
        List<AgmtWorkloadDetail> existsWorkloadDetailList = workloadDao.getAllAgmtWorkloadDetailByScheduleIdAndMonthsAndCategory(manSchId, months, staffId, staffCatCode);
        existsWorkloadDetailList.forEach(x -> {
            workloadDao.remove(x);
            });
        }
    for (int k = 0; k < months.size() && k < workLoadList.size(); k++) {
        AgmtWorkloadDetail wlDetail = new AgmtWorkloadDetail();
        BigDecimal workload = BigDecimal.ZERO;
        try {
            workload = ((BigDecimal) workLoadList.get(k));
        } catch (Exception e) {
        }

        wlDetail.setSummaryId(wSummary.getSummaryId());
        wlDetail.setWorkloadDate(new Integer(months.get(k)));
        wlDetail.setWorkloadUnit(WorkloadUnit.WEEK.getValue());
        wlDetail.setWorkload((workload != null ? workload : new BigDecimal(0)));
        wlDetail.setStaffCatCode(staffCatCode);
        wlDetail.setCreateDate(LocalDateTime.now());
        wlDetail.setCreateUser(userId);
        wlDetail.setUpdateDate(LocalDateTime.now());
        wlDetail.setUpdateUser(userId);
        workloadDao.persist(wlDetail);
        }
    }

下面是insertOrUpdateManningSchedule（）的代码

public Integer insertOrUpdateManningSchedule (Integer agreementId, Integer groupId, Integer staffId, String tempId, int userId, String agmtNo) {
    AgmtManSch manningSchedule = manningScheduleDao.getAllAgreementManningScheduleByAgmtIdAndGroupId(agreementId, groupId);

    final LocalDateTime now = LocalDateTime.now();
    if (manningSchedule != null) {
    manningSchedule.setSubmitDate(LocalDateTime.now());
    manningSchedule.setHibVersion(manningSchedule.getHibVersion()+1);
    manningSchedule.setUpdateDate(now);
    manningSchedule.setUpdateUser(userId);  
    workloadDao.merge(manningSchedule);
    } else {
        // create a new manning schedule as there is no recored with the given project Id
        AgmtManSch agmtManSch = new AgmtManSch();
        agmtManSch.setGroupId(groupId);
        agmtManSch.setAgmtId(agreementId);
        agmtManSch.setAgmtNo(agmtNo);   
        agmtManSch.setYear(now.getYear());
        agmtManSch.setPeriod(now.getMonthValue());              
        agmtManSch.setSubmitDate(now);      
        agmtManSch.setCreateDate(now);
        agmtManSch.setCreateUser(userId);
        agmtManSch.setUpdateDate(now);
        agmtManSch.setUpdateUser(userId);   
        workloadDao.persist(agmtManSch);
    }
    return manningSchedule.getScheduleId();
}

以下是我得到的例外情况

提前谢谢！

为许多用户选择和删除许多行（大约24000）时，SQL Server超时
