spring org.hibernate.PropertyValueException:非空属性引用空值或 transient 值：仅限@Scheduled例外

我正在为一个JPA项目（Hibernate with Spring）编写代码。
我面临的问题是，当我使用@Scheduled注解执行下面的interestCalculation()方法时，我会遇到异常：

org.springframework.dao.DataIntegrityViolationException: not-null property references a null or transient value : com.mad.app.domain.DemandLedgerMap.demandLedger; nested exception is org.hibernate.PropertyValueException: not-null property references a null or transient value : com.mad.app.domain.DemandLedgerMap.demandLedger

在quartsTestdDisplay()中的for循环执行完毕后。但是，当我执行相同的方法时，没有预定的数据，在for循环执行完毕后保持/更新。只有当方法从@Scheduled触发时，才会抛出异常。
下面是我的代码，一个是deligate层类，另一个是service层类。在delegate层，我使用了@Scheduled作为调度触发器interestCalculation()。

@Controller
  public class DcbDailyBalanceDelegate {

@Autowired
private DcbDailyBalanceService dcbDailyBalanceService;
/**
 * El name.
 */
public static final String EL_NAME = "#{dcbDailyBalanceDelegate}";

@Transactional
@Scheduled(cron="0 37 11 ? * THU")
public void interestCalculation()
{
    //dcbDailyBalanceService.dcbBalanceToDcbDailybalance();
    dcbDailyBalanceService.quartsTestdDisplay();
}

}

@Transactional
public void quartsTestToUpdate()
{

    for (int i = 0; i < 3000; i++) {

        DcbDailyBalance dcbDailyBalance=new DcbDailyBalance();

        DemandLedgerMap  demandLedgerMap=new DemandLedgerMap();

        DledgerApplicableMap dledgerApplicableMap=new DledgerApplicableMap();

        demandLedgerMap.setDldgrMapId(1);
        dledgerApplicableMap.setDlamapId(1);

        dcbDailyBalance.setDcbbalAmount(1000+i);
        dcbDailyBalance.setDcbbalDataSource((byte) 0);
        dcbDailyBalance.setDcbbalDate(1409120385);
        dcbDailyBalance.setDcbbalIntrstAmount(100+i);
        dcbDailyBalance.setDcbbalLastupdated(1409120385);
        dcbDailyBalance.setDemandLedgerMap(demandLedgerMap);
        dcbDailyBalance.setDledgerApplicableMap(dledgerApplicableMap);

        DcbDailyBalance dailyBalance=dailyBalanceDao.update(dcbDailyBalance);

     }
    }

以下是例外情况：

您正在尝试持久化具有DemandLedgerMap类DcbDailyBalance类但是在DemandLedgerMap中，dldgrMapRowStatus和demandLedger列设置为nullable=false，并且您没有为此传递值
这就是为什么当你试图持久化DcbDailyBalance时，它会抛出异常。希望它是清楚的。

您需要将“dcbDailyBalance”添加到demandLedgerMap列表中，然后插入demandLedgerMap。当您尝试更新dcbDailyBalance时，它会尝试保存dcbDailyBalance，然后“级联”并保存demandLedgerMap，因此demandLedgerMap“为空值或临时值”。保存demandLedgerMap将创建demandLedgerMap.id，它将不再是临时值，然后您可以保存dcbDailyBalance。请尝试以下操作：

demandLedgerMap.addaddDcbDailyBalance(dcbDailyBalance);
demandLedgerMapDAO.update(dailyBalanceDao);

属性值异常：非空属性引用空值或 transient 值：com.kssidc.app.domain.DemandLedgerMap.demandLedger
这清楚地表明，在类DemandLedgerMap中，您正试图持久化demandLedger，它是一个不可空的字段。因此，当您使用dcbDailyBalanceService.quartsTestdDisplay();时，您并没有为此提供值。
因此，在持久化/更新此值时，它将查找demandLedger的值，并且它将获得空值，因此它将抛出异常。
