如果在第二次交易之前失败，@ Transnsal会回滚吗？

在数据库操作期间，无论是否失败，Spring事务管理回滚操作是否成功？例如：

@Service
@Transactional
public class PurchaseInvoiceLineServiceImpl implements PurchaseInvoiceLineService {

    @Autowired
    private PurchaseInvoiceLineRepository purchaseInvoiceLineRepository;
    @Autowired
    private StockRepository stockRepository;
    @Autowired
    private PurchaseInvoiceRepository purchaseInvoiceRepository;
    @Autowired
    private SupplierDebtRepository supplierDebtRepository;

    public <S extends PurchaseInvoiceLine> S save(S purchaseInvoiceLine) {
        purchaseInvoiceLineRepository.save(purchaseInvoiceLine);
        updatePurchaseInvoiceAmountForCreate(purchaseInvoiceLine);
        // update stock
        Stock stock = stockRepository.getStockByProduct(purchaseInvoiceLine.getProductId());
        stock.setQuantity(stock.getQuantity().add(purchaseInvoiceLine.getQuantity()));
        stockRepository.update(stock);
        // update debt
        PurchaseInvoice purchaseInvoice = purchaseInvoiceRepository.findOne(purchaseInvoiceLine.getPurchaseInvoiceId());
        SupplierDebt supplierDebt = supplierDebtRepository.getDebtBySupplierId(purchaseInvoice.getSupplierId());
        supplierDebt.setAmount(supplierDebt.getAmount().add(purchaseInvoiceLine.getLineAmount()));
        supplierDebtRepository.update(supplierDebt);
        return purchaseInvoiceLine;
    }
}

如果@Transactional在以下行（这不是数据库操作）失败时，应该回滚整个事务吗？

stock.setQuantity(stock.getQuantity().add(purchaseInvoiceLine.getQuantity()));

更新

因为表“stock”没有任何记录，所以在// update stock，读取的stock对象为null，因此在它尝试设置的下一行抛出NullPointerException数量。这是整个堆栈跟踪：

取决于 - 如果事务已经启动（实现/业务逻辑依赖），它将被回滚 - 但也可以提交 - 没有操作。

必须完成事务才能释放数据库连接。回滚是最常见的解决方案。更多的是它是最普遍的，因为它适用于大多数情况 - 即使是嵌套和扩展事务。

答案 1 :(得分：1)

是的，根据Spring documentation：

  

在默认配置中，Spring Framework的事务基础结构代码仅在运行时未经检查的异常情况下标记用于回滚的事务;也就是说，抛出的异常是RuntimeException的实例或子类。 （错误也将 - 默认情况下 - 导致回滚）。从事务方法抛出的已检查异常不会导致在默认配置中回滚。

鉴于您的失败标准是未经检查的异常。

因为您将类标记为@Transactional，所以当您调用PurchaseInvoiceLineService.save()时，代理将启动事务，如果方法执行存在任何异常，请捕获它们并回滚事务。
