Question

我们遇到的问题仅出现在生产环境中。

RowHandler应该执行大约63行，但它无法处理1到3行。

我们的RowHandler中没有连接/光标关闭。

我的RowHandler看起来像：

public class CustomerRowHandler extends AbstractRowHandler {
    private UserContextTiny userCtx;
    private MarketingActionData mrkData;
    private TaskManager taskManager;
    private Logger logger = new Logger(getClass());

    public CustomerRowHandler(UserContextTiny userCtx, TaskData task, MarketingActionData mrkData) {
        this.userCtx = userCtx;
        this.mrkData = mrkData;
        this.taskManager = new TaskManager(task.getId());
    }

    public void handleRow(Object valueObject) {
        String methodName = "handleRow";
        MarketingPersonalData recipient = (MarketingPersonalData)valueObject;
        try {
            MarketingActionDataSource ds = new MarketingActionDataSource();
            Account account = recipient.getAccount();
            Customer customer = recipient.getCustomer();
            if (account != null) {
                Long tierId = AccountDAO.getInstance().getAccountTier(account.getAccId(), DateTimeProvider.getInstance().getCurrentDate());
                DictionaryObject tier = (DictionaryObject) CLMCacheHolder.getGlobal().getRegion(EJBCacheRegions.TIERS).getElement(tierId);
                account.setAccTierCode(tier.getCode());
                account.setAccTierName(tier.getName().getValue(customer.getCusLngCode()));
                account.setTierId(tierId);
            }
            ds.setAccountData(account);
            ds.setCustomerData(customer);
            ds.setProspectData(recipient.getProspect());

            GeneratedMessageData genMsg = MessageProcessor.generateMessage(NotificationTemplateData.Type.MARKETING_ACTION, recipient.getCustomer().getCusLngCode(), mrkData.getChnCode(), mrkData.getNtmId(), ds);
            SendNotificationData sendDto = new SendNotificationData(genMsg);
            sendDto.setMrkId(mrkData.getId());
            sendDto.setToCusId(recipient.getCustomer().getCusId());
            sendDto.setAdvId(mrkData.getAdvId());
            sendDto.setType(CommunicationData.Type.MARKETING_ACTION);
            sendDto.setExternalId(CommunicationDAO.generateExternalId(sendDto.getType(), mrkData.getId(), mrkData.getCreateDate()));
            if (mrkData.getExpirationDate() != null) {
                sendDto.setExpirationDate(new Timestamp(mrkData.getExpirationDate().getTime()));
            }
            if (mrkData.getSendAfterDate() != null) {
                sendDto.setSentAfter(new Timestamp(mrkData.getSendAfterDate().getTime()));
            }
            if (NotificationTemplateData.Handler.SOAP.equals(genMsg.getNtmHandler()) || NotificationTemplateData.Handler.SYNC.equals(genMsg.getNtmHandler()) || Channels.SMS.equals(mrkData.getChnCode())) {
                sendDto.setStatus(CommunicationData.Status.PENDING);
            }
            sendDto.setChannel(mrkData.getChnCode());
            // attach coupons generated in this communication
            sendDto.setCoupons(new ArrayList<Long>());
            if (ds.isCouponDataAvailable()) {
                for (CouponData coupon : ds.getCoupons()) {
                    sendDto.getCoupons().add(coupon.getId());
                }
            }

            // send notification
            notificationManager.sendNotification(userCtx, sendDto, mrkData.isPermissionIgnore(), false, false);
            sendCount++;

        } catch (ApplicationException e) {
            rejectCount++;
            logger.info(methodName, "Mailing not sent due to: " + e.getMessage(), e);
            taskManager.taskLog("Mailing not sent to customer \"" + recipient.getCustomer().getCusFirstName() + " " + recipient.getCustomer().getCusLastName() + "\" (id: " + recipient.getCustomer().getCusId() + ") due to: " + e.getMessage(), INFO);
        } catch (SystemException e) {
            rejectCount++;
            logger.info(methodName, "Mailing not sent due to: " + e.getMessage(), e);
            taskManager.taskLog("Mailing not sent to customer \"" + recipient.getCustomer().getCusFirstName() + " " + recipient.getCustomer().getCusLastName() + "\" (id: " + recipient.getCustomer().getCusId() + ") due to: " + e.getMessage(), INFO);
            throw e;            
        } 
    }
}

它被用于：

public void selectMarketingPersonalData(UserContextTiny userCtx, Long mrkId, RowHandler rh) {
    getSqlMapClientTemplate().queryWithRowHandler("MARKETING_ACTION.selectMarketingPersonalData", mrkId, rh);
}

查询执行的内容：

这个问题可能是什么原因？我们无法在测试环境中重现它。

Answer 1

在很多情况下，结果集会自动关闭，就像生成它的Statement对象被关闭，重新执行或用于从多个结果序列中检索下一个结果一样。

有关详细信息，请查看official documentation

如果您可以在问题中提供代码而不是堆栈跟踪，那会更好。

iBatis，queryWithRowHandler ResultSet已经关闭
