春季@Transaction不开始交易

java transactions hibernate spring transactional
2022-09-03 15:59:29

我正在使用Spring 3和Hibernate 3。我正在尝试配置Spring声明式事务，但无论我尝试什么，Spring事务都没有开始。

这是我的配置

文件：应用程序上下文休眠.xml

<tx:annotation-driven transaction-manager="txManager" />

<bean id="txManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory" />
</bean>

<bean id="mdbDataSource" class="org.apache.commons.dbcp.BasicDataSource">
...
</bean>

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
 <property name="dataSource" ref="mdbDataSource" />
  <property name="annotatedClasses">
.....
</bean>

我有一个类ServiceLocatorImpl，它实现了ServiceLocator接口

@Service("serviceLocator")
@Transactional
public class ServiceLocatorImpl implements  ApplicationContextAware, Serializable, ServletContextAware, ServiceLocator {
public ResultObject executeService( Map objArgs )
{
      if(TransactionSynchronizationManager.isActualTransactionActive()) {
          LOGGER.debug("ServiceLocator:executeService - Active transaction found");
      } else {
        LOGGER.error("No active transaction found");
      }
         ......
}
     ....
}

在我看来，我所有的配置都是正确的。但是当调用 executeService 方法时，TransactionSynchronizationManager.isActualTransactionActive（） 总是返回 false。

请帮我解决这个问题。如果需要更多信息，请告诉我。

更新：我已将 ServiceLocator 连接到其他类之一，如下所示：

@Autowired
private ServiceLocator serviceLocator; // ServiceLocator is interface

我使用的是春季3.0.0版本。

executeService（） 是 ServiceLocator 接口中定义的方法之一。我更新了代码以引发异常，而不仅仅是记录错误。以下是堆栈跟踪，我在此跟踪中没有看到任何代理创建。请帮忙。

更新 [已解决]我已解决问题。在给出如何修复的答案之前，我需要提供一些更多信息。我在我的项目中使用Spring MVC。控件 DispatchServlet 是在 web.xml中配置的。这个前端控制器有一个配置xml文件abc-servlet.xml（abc是web.xml中的servlet名称）。我还有其他弹簧配置文件，它们的定义如.其中一个文件是文件。context-paramweb.xmlapplicationContext-hibernate.xml

我在文件中定义了 和 。今天我想知道@Autowired和@Transactional一起工作，所以我谷歌了信息，并找到了这个线程txManager<tx:annotation-driven />applicationContext-hibernate.xml

http://forum.springsource.org/showthread.php?48815-Repository-Autowired-Transaction-not-returning-proxy-and-causes-exception

线程讨论类似的问题，这解决了问题。

I implemented one of the suggestion and added <tx:annotation-driven .../> to my servlet's application context xml and it fixes the problem.

以为我也把我的文件移到了abc-servlet.xml文件，它工作了。<tx:annotation-driven />

我的日志现在应该包含所需的消息：

[venice] DEBUG [http-8080-1] 27 Sep 2011 14:24:06,312 ServiceLocatorImpl.logTransactionStatus(100) | ServiceLocator:executeService - Active transaction found

感谢大家的帮助。也许这些信息会对某人有所帮助。我仍然想听听为什么它不能更早地工作的解释。


答案 1

我的猜测是，你正在尝试做这样的事情：

ServiceLocator locator = new ServiceLocatorImpl();
...
locator.executeService(someMap);

然后惊讶于没有交易。事务管理和所有其他Spring服务仅适用于应用程序上下文中的Bean*。您需要以某种方式从上下文中获取实例，而不仅仅是实例化实例。或者，您的定位器 Bean 位于与声明 .tx:annotation-driven

*除非您使用AspectJ构建或加载时间字节码编织与Spring。

编辑：问题正是我说的（第二部分）。创建两个应用程序上下文。您在第一个中创建了 ServiceLocator，但在第二个中只启用了注释驱动的事务。您似乎不了解上下文之间的边界。一般来说 - 至少在我的经验中 - “业务”bean，就像您的ServiceLocator一样，存在于根上下文中，这是由 启动并通过.配置或由 DispatcherServlet 使用的控制器和其他 Bean 位于与该文件配置的 servlet 关联的另一个上下文中。此上下文成为根上下文的子上下文，其中的 Bean 可以与根上下文中的 Bean 一起注入，但反之则不然。ContextLoaderListenercontextConfigLocation*-servlet.xml

从我的角度来看，你通过添加到与 DispatcherServlet 关联的子上下文，打破了比以前更糟糕的事情。相反，您应确保在根上下文中创建 ServiceLocator，其中事务服务已可用且位于其所属位置。tx:annotation-driven


答案 2

您应该简单地将“txManager”重命名为“transactionManager”。来自 的 JavaDoc：EnableTransactionManagement

...在 XML 情况下，名称为“transactionManager”。默认情况下，它是硬连线的，以查找名为“transactionManager”的bean...<tx:annotation-driven/>
