spring - @Transactional超时属性具有不同传播方式的工作方式

我对@Transactional 超时属性的行为感到困惑

我有以下顺序

Main ->
UserExecutionServiceImpl.executeRecordInvoice ->
ProcessInvoiceServiceImpl.recordInvoice ->
WarehouseServiceImpl.checkStockAvailability

强制回滚异常超时设置为0。

如果executeRecordInvoice 具有@Transactional(timeout=0)，则会引发异常，并停止所有操作。有道理

如果 executeRecordInvoice 具有@Transactional和 recordInvoice 具有@Transactional(timeout=0)，则不会引发异常。实际上，超时值已被忽略。

我可以假设是因为事务处理实际上是从 executeRecordInvoice 开始的，而且因为这两种方法默认都具有Propagation.Required，这意味着，第二个方法( recordInvoice )被认为是在第一个事务( executeRecordInvoice )内，即已存在的事务跑步

更重要的是，我做了两个简单的实验:
  • 如果 executeRecordInvoice 具有@Transactional，而 recordInvoice 具有@Transactional(propagation.Propagation.REQUIRES_NEW, timeout=0)，则引发异常。现在可以使用，因为新的事务在记录中开始发票，因此考虑了超时。
  • 直接从Main类中调用ProcessInvoiceServiceImpl.recordInvoice，使用@Transactional(propagation.Propagation.REQUIRED, timeout=0)或@Transactional(propagation.Propagation.REQUIRES_NEW, timeout=0)调用它，再次考虑超时。

    • 到这里为止，我很好，所有人都有道理。但是将1和2应用于 WarehouseServiceImpl.checkStockAvailability ，则不起作用:
  • 如果 executeRecordInvoice 和 record发票具有@Transactional(因此默认为Propagation.REQUIRED)和 checkStockAvailability 具有@Transactional(propagation.Propagation.REQUIRES_NEW, timeout=0)。唯一的例外是而不是!
  • 直接从Main类中调用WarehouseServiceImpl.checkStockAvailability，它是@Transactional(propagation.Propagation.REQUIRED, timeout=0)或@Transactional(propagation.Propagation.REQUIRES_NEW, timeout=0)，再次是超时是，而不是。

    • 类声明
    @Service
@Transactional
@Scope("prototype")
public class WarehouseServiceImpl implements WarehouseService {

    // Unique method implementation
    @Transactional(propagation = Propagation.REQUIRES_NEW, timeout=0)
    public boolean checkStockAvailability(Product product, BigDecimal quantity) {

        ...

    return true;

    }
}

    任何想法或建议都欢迎。

    Spring Framework 4.0.5

    谢谢。

    在提出安德烈的建议之后，我有以下几点:
    @Transactional
@Scope("prototype")
@Service("processInvoiceService")
public class ProcessInvoiceServiceImpl implements ProcessInvoiceService {

    @Override
    @Transactional(propagation = Propagation.REQUIRES_NEW, timeout=0)
    public void recordInvoice(InvoiceHeader invoiceHeader) {

    并在MainTest类中
    ProcessInvoiceService processInvoiceService = context.getBean(ProcessInvoiceService.class);

        try{
            processInvoiceService.recordInvoice(invoiceHeader03);
        }
        catch(Exception e){
            logger.error("ERROR ALFA: {}", e.getMessage());
        }

    错误未按预期抛出。

    Omicron

    新的更新代码:
    @Service
@Transactional
@Scope("prototype")
public class WarehouseServiceImpl implements WarehouseService {

    private static final Logger logger = LoggerFactory.getLogger(WarehouseServiceImpl.class);

    private ProductService productService;

    @Autowired
    public WarehouseServiceImpl(ProductService productService){
        this.productService = productService;
    }

    @Override
    @Transactional(propagation = Propagation.REQUIRES_NEW, timeout=0)
    public boolean checkStockAvailability(Product product, BigDecimal quantity) {

        logger.info("Amount: {}", this.productService.getAmountProducts());
        ...
        return true;

    }

}

    上面显示的代码对于这两个项目是相同的，对于一个使用JdbcTemplate的项目，一切正常，抛出了预期的错误，但是使用Hibernate的另一个项目未引发预期的错误。在结果输出下方。

    有一些线索吗？ DataAccess当然存在...

    最佳答案

    查看您的第一个日志(与recordInvoice和checkStockAvailability的超时问题有关)，这些确实表明事务行为已正确应用:在Java代码级别，事务已启动并提交。日志中唯一的区别是，使用recordInvoice时，将对数据库执行实际查询，而使用checkStockAvailability时，则没有这种查询。

    对此的可能答案是，如果数据库没有 Activity ，则没有数据库级事务。 Java代码中的内容反映在数据库级别。例如，如果您打开MySQL控制台并在表中插入内容，则最后需要提交以查看DB中的结果。

    与第二个问题有关，您在其中一个测试中使用JdbcTemplate，而在另一项测试中使用Hibernate(带有HibernateTransactionManager)，查看source code for the Hibernate transaction似乎只考虑了严格大于0的值。因此，一个简单的测试将超时设置为一秒，而在事务方法checkStockAvailability中，可以添加一个Thread.sleep(1500)可以表明，忽略了0秒的超时值，从而解释了测试结果。
