嗯...试图在谷歌和这里找到但失败了。这是我的故事:
- Spring MVC 3.1.1 发布
- Spring Data JPA 1.1.0 发布
- 休眠 3.6.9.Final
问题:我有带有 @Transactional(propagation=Propagation.REQUIRES_NEW) 注释的方法 save(...) 。但是没有创建交易。
其他发现:1)当我使用其他服务的@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)这个方法所在的服务被代理包装(我在调试中看到)和从控制器调用的方法,所以调用通过代理。
3) 根应用程序上下文中的两个服务。log.error(context) 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
下面是方法的代码:
@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:
