Spring @Transaction未开始交易

Question

我正在使用Spring 3与Hibernate 3.我试图配置Spring声明式事务，但无论我尝试什么，Spring事务都没有开始。

这里是我的配置

文件：的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> 

我有一个类ServiceLocatorImpl它实现的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，我的所有配置是正确的。但是，当调用executeService方法时，TransactionSynchronizationManager.isActualTransactionActive（）始终返回false。

请帮我解决这个问题。让我知道是否需要更多信息。

更新： 我了有线的服务定位成其他类之一，如下：

@Autowired 
private ServiceLocator serviceLocator; // ServiceLocator is interface 

我使用Spring 3.0.0版本。

executeService（）是ServiceLocator接口中定义的方法之一。我更新了代码来抛出异常，而不是只记录一个错误。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[解决] 我得到了这个问题解决。在给出答案之前，我需要提供更多信息。我在我的项目中使用Spring MVC。控制DispatchServlet在web.xml中配置。此前端控制器具有配置xml文件abc-servlet.xml（abc是web.xml中的servlet名称）。我还有其他的弹簧配置文件，这些文件在web.xml中定义为context-param。其中一个文件是applicationContext-hibernate.xml文件。

我在applicationContext-hibernate.xml文件中定义了txManager和<tx:annotation-driven />。今天，我想知道是否@Autowired和@Transactional工作一起，所以我谷歌的信息，发现这个线程

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

线程谈论类似的问题，而这个问题解决了。

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

想，我也动了我的<tx:annotation-driven />到ABC-servlet.xml文件和它的工作。现在

我的日志shoulding所需的信息：

[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。我仍然希望听到有关解释，为什么它不能提前工作。

Answer 1

我的猜测是，你正在试图做一些事情，如：

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

，然后是惊讶，有没有交易。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，而不是仅实例化一个实例。否则，您的定位器bean位于与声明tx:annotation-driven的应用程序环境不同的应用程序环境中。

*除非你使用AspectJ build- or load-time bytecode weaving春暖花开。

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。你在第一个创建你的ServiceLocator，但是你只在第二个中启用注解驱动的事务。您似乎不了解上下文之间的界限。通常 - 至少在我的经验中 - “业务”bean，就像ServiceLocator一样，存在于根环境中，该环境由ContextLoaderListener开始，并通过contextConfigLocation进行配置。配置DispatcherServlet或由DispatcherServlet使用的控制器和其他bean位于与由该*-servlet.xml文件配置的servlet相关的另一个上下文中。这个上下文变成了根上下文的子上下文，并且其中的bean可以从根上下文注入bean，尽管反过来也是如此。

从我的角度来看，通过将tx:annotation-driven添加到与DispatcherServlet关联的子上下文中，您已经破坏了比以前更糟糕的事情。相反，您应该确保ServiceLocator是在根环境中创建的，其中事务服务已经可用并且属于它们所在的位置。

Answer 2

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

...在XML的情况下，名称是“transactionManager”。 <tx:annotation-driven/>被硬连接以默认寻找名为“transactionManager”的bean ...
