@transactional带注释的类用代理包装，但不创建事务

Question

好尝试在google和此处查找，但失败。以下是我的故事：

• Spring MVC 3.1.1版本
• Spring Data JPA 1.1.0版本
• Hibernate3.6.9。最终版本

问题：我有方法保存（…）使用@Transactional（传播=传播。需要\u NEW）注释。但未创建事务。

其他发现：1）当我使用来自其他服务的@Transactional方法进行注释时，正在创建事务。

21:49:13.397 [DEBUG] (http-8080-2) org.springframework.orm.jpa.JpaTransactionManager  - Creating new transaction with name [com.xen.components.page.PageServiceImpl.findAllOrdered]: PROPAGATION_REQUIRED,ISOLATION_DEFAULT; ''

2）此方法所在的服务被代理包装（我在调试中看到），并且从控制器调用方法，因此调用通过代理。
3）根应用程序上下文中的两个服务。log.error（上下文）的输出：

OrderServiceImpl  - Root WebApplicationContext: startup date [Tue Sep 17 21:48:30 FET 2013]; root of context hierarchy
PageServiceImpl  - Root WebApplicationContext: startup date [Tue Sep 17 21:48:30 FET 2013]; root of context hierarchy

以下是方法代码：

@Service
public class OrderServiceImpl extends CRUDServiceImpl<Order> implements OrderService {
private static final Logger log = Logger.getLogger(OrderServiceImpl.class);

@Autowired
private OrderRepository repo;

@Autowired
private OrderItemService orderItemService;

@Override
protected CRUDRepository<Order> getRepository() {
    return repo;
}

@Override
@Transactional(propagation=Propagation.REQUIRES_NEW)
public Order save(Order entity) {
    if (entity.getCreationDate() == null) {
        entity.setCreationDate(new Date());
    }

    if (entity.getId() == null) {
        increasePopularityForProductsInOrder(entity);
        // throws NoTransactionException: No transaction aspect-managed TransactionStatus in scope
        TransactionAspectSupport.currentTransactionStatus().setRollbackOnly();

        decreaseStockNumberForSkusInOrder(entity);
    }

    return super.save(entity);
}

private void increasePopularityForProductsInOrder(Order order) {
    List<OrderItem> items = order.getItems();

    for (OrderItem item : items) {
        orderItemService.increasePopularity(item);
    }
}

private void decreaseStockNumberForSkusInOrder(Order order) {
    List<OrderItem> items = order.getItems();

    for (OrderItem item : items) {
        orderItemService.removeFromStock(item);
    }
}
}

从控制器调用此方法。控制器代码很简单，只有验证和orderService.save（...）调用。这是我的配置：

更新：CartController。JAVA

@Controller
public class CartController {
    private static final Logger log = Logger.getLogger(CartController.class);

...

@RequestMapping(value = "/cart/submit-order", method = RequestMethod.POST)
    public String submit(@RequestParam String email, @RequestParam long deliveryType, Model uiModel, HttpServletRequest request, RedirectAttributes redirectAttrs) {
        Order order = CartHelper.getOrderFromRequest(request);
        uiModel.addAttribute("email", email);

        // 1. check if address is set
        if (StringUtil.isEmpty(order.getClientInfo().getFirstName())) {
            MessageBean.createErrorMessage("cart.enter-address.error").displayMessage(uiModel);
            populateForm(uiModel, order);
            return "cart";
        }

        // 2. check if specified deliveryType exist
        DeliveryType type = null;
        try {
            type = deliveryTypeService.findOne(deliveryType);
        } catch (NotFoundException nfe) {
            MessageBean.createErrorMessage("cart.invalid-delivery-type.error").displayMessage(uiModel);
            populateForm(uiModel, order);
            return "cart";
        }
        order.setDeliveryType(type);

        // 3. check if email is valid
        if (!StringUtil.isEmailValid(email)) {
            MessageBean.createErrorMessage("cart.invalid-email.error").displayMessage(uiModel);
            populateForm(uiModel, order);
            return "cart";
        }
        order.getClientInfo().setEmail(email);

        // 4. check if order is not empty
        if (order.isEmpty()) { // should not be possible
            log.warn("Empty order submission registered! " + order);
            return "cart/empty";
        }

        order = orderService.save(order);
        CartHelper.updateOrderForRequest(request, order);

        // 5. send notification to client
        try {
            sendNotificationToClient(order, request);
            redirectAttrs.addFlashAttribute(MessageBean.MESSAGE_BEAN_KEY, MessageBean.createSuccessMessage("cart.order.successfuly.created"));
        } catch (Exception e) {
            redirectAttrs.addFlashAttribute(MessageBean.MESSAGE_BEAN_KEY, MessageBean.createErrorMessage("cart.failed.to.send.notification.during.order.saving"));
        }

        return "redirect:/orders/success";
    }

...

}

如果你有什么想法，请发布它。我对此感到疯狂。

Answer 1

初始化注释时，请尝试指定事务管理器，以便更新配置文件，如下所示：

<tx:annotation-driven transaction-manager="transactionManager" proxy-target-class="true"/>

希望这有帮助。
