java - Spring @Transaction 未启动事务

标签 java hibernate spring transactions transactional

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 事务都没有启动。

这是我的配置

文件:applicationContext-hibernate.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>

我有一个实现 ServiceLocator 接口(interface)的类 ServiceLocatorImpl

@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，我的所有配置都是正确的。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 Spring 3.0.0 版本。

executeService() 是 ServiceLocator 接口(interface)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，我在此跟踪中看不到任何代理创建。请帮忙。

更新 [已解决] 我解决了这个问题。在给出解决方法之前，我需要提供更多信息。我在我的项目中使用 Spring MVC。控件 DispatchServlet 在 web.xml 中配置。这个前端 Controller 有一个配置 xml 文件 abc-servlet.xml(abc 是 web.xml 中的 servlet 名称)。我还有其他定义为 context-param 的 spring 配置文件在 web.xml .其中一个文件是 applicationContext-hibernate.xml文件。

我定义了 txManager和 <tx:annotation-driven /> , 在 applicationContext-hibernate.xml文件。今天我想知道@Autowired 和@Transactional 是否一起工作，所以我谷歌了信息，找到了这个帖子

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

帖子讲了类似的问题，这样就解决了。

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

以为我也搬了<tx:annotation-driven />进入 abc-servlet.xml 文件，它工作。

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。可能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。

最佳答案

我的猜测是您正在尝试执行以下操作:

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*。您需要以一种或另一种方式从上下文中获取您的实例，而不仅仅是实例化一个。否则，您的定位器 bean 位于与您声明 tx:annotation-driven 的应用程序上下文不同的应用程序上下文中。 .

*除非你使用 AspectJ build- or load-time bytecode weaving与 Spring 。

编辑:问题正是我所说的(第二部分)。您创建两个应用程序上下文。您在第一个中创建了 ServiceLocator，但您只在第二个中启用了注释驱动的事务。您似乎不了解上下文之间的界限。一般来说——至少在我的经验中——“业务”bean，比如你的 ServiceLocator，存在于根上下文中，它是由 ContextLoaderListener 启动的。并通过 contextConfigLocation 配置.配置 DispatcherServlet 或被 DispatcherServlet 使用的 Controller 和其他 bean 存在于与 *-servlet.xml 配置的该 servlet 关联的另一个上下文中。文件。此上下文成为根上下文的子上下文，其中的 bean 可以从根上下文中注入(inject) bean，反之亦然。

在我看来，您通过添加 tx:annotation-driven 使事情变得比以前更糟了。到与您的 DispatcherServlet 关联的子上下文。相反，您应该确保在根上下文中创建 ServiceLocator，其中事务服务已经可用并且它们所属的位置。
