Question

我正在处理Spring声明式事务处理赋值。

我的问题是，数据在交易过程中处于中间位置。我只使用'new'运算符将数据设置为新创建的对象。为了设置数据我点击DB并且必须获取一些数据。在执行setter方法的一半方法后，它会刷新一些数据

例如：
联系contact = DB.loadContact（）; - ＆GT;选择查询

Consignment.setContact（contact）;

- ＆GT;当执行通过此行时，数据将提交到DB

请参阅以下代码以进一步了解

// code 01

    @Transactional(propagation=Propagation.REQUIRES_NEW, rollbackFor=Exception.class)
    public void editInternationalExportConsigment (){

    // calling a nested method
    internationalExportConnoteFormToDomainTranslator.translate(exportConssignmentWrapper, user);
..........
}



 //code 02
    @Transactional(propagation=Propagation.SUPPORTS)
    public InternationalConsignment translate(AbstractFormWrapper defaultWrapper, Person user)  {

    // set values to a newly created object

   consignment.setSenderContact(contact);
        consignment.setCustomerReference(consignmentVO.getCustomerRef());

    // I have called no insert or update calls in the middle, 
    //There are only select queries hit the db middle in the process and those also execute under transactional scope.

     Contact contact = 
 inquiry.loadCustomerContactById(consignmentVO.getCustomerContactId().intValue());

    // when executing this line, it commit the Data to DB
   consignment.setContact(contact);
   ...........
   ...........
   }

我使用以下方式监控交易，并且记录器通过流程显示相同的活动交易

logger.error("######Method Name ==="+str+"==="+ Thread.currentThread().getStackTrace());
            logger.error("######Transaction Name ==="+str+"==="+TransactionSynchronizationManager.getCurrentTransactionName());
            logger.error("######Transaction Active ==="+str+"==="+TransactionSynchronizationManager.isActualTransactionActive());
            logger.error("######Transaction Readonly ==="+str+"==="+ TransactionSynchronizationManager.isCurrentTransactionReadOnly())

我被困在这里，非常感谢有人能在这里给我一个线索。

谢谢！

---详细的代码块我有问题 -

private void translateOrginDestinationInformation(InternationalExportConsignmentFormWrapper consignmentVO, InternationalConsignment consignment, ISVCAIXISInquiry inquiry) {
        Country destination = inquiry.loadCountryById(consignmentVO.getReceiverCountryID());
        consignment.setDestination(destination);
        consignment.setDestinationCity(inquiry.loadByCityId(consignmentVO.getReceiverCityID()));

        TestTransactionIndicatingUtil.testTransactionalStatus("originaldestination translate");
        Contact contact = inquiry.loadCustomerContactById(consignmentVO.getCustomerContactId().intValue());


        if (contact != null && contact.getCity() != null) {
              consignment.setOrgin(contact.getCity().getCountry());
              consignment.setUniqueOriginCountry((contact.getCity().getCountry()!=null)?contact.getCity().getCountry().getId():null);
              consignment.setOrginCity(contact.getCity());
        }
    }

Spring @Transactional数据在此过程中被提交到DB中间
