Spring @Transaction未開始交易

Question

我正在使用Spring 3與Hibernate 3.我試圖配置Spring聲明式事務，但無論我嘗試什麼，Spring事務都沒有開始。

這裏是我的配置

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> 

我有一個類ServiceLocatorImpl它實現的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"); 
     } 
     ...... 
} 
    .... 
} 

在我看來，我的所有配置是正確的。但是，當調用executeService方法時，TransactionSynchronizationManager.isActualTransactionActive（）始終返回false。

請幫我解決這個問題。讓我知道是否需要更多信息。

更新： 我了有線的服務定位成其他類之一，如下：

@Autowired 
private ServiceLocator serviceLocator; // ServiceLocator is interface 

我使用Spring 3.0.0版本。

executeService（）是ServiceLocator接口中定義的方法之一。我更新了代碼來拋出異常，而不是隻記錄一個錯誤。以下是堆棧跟蹤，我在此跟蹤中看不到任何代理創建。請幫忙。

更新[解決] 我得到了這個問題解決。在給出答案之前，我需要提供更多信息。我在我的項目中使用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名稱）。我還有其他的彈簧配置文件，這些文件在web.xml中定義爲context-param。其中一個文件是applicationContext-hibernate.xml文件。

我在applicationContext-hibernate.xml文件中定義了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，發現這個線程

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

線程談論類似的問題，而這個問題解決了。

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

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

我的日誌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

感謝大家的幫助。可能這些信息會對某人有所幫助。我仍然希望聽到有關解釋，爲什麼它不能提前工作。

Answer 1

我的猜測是，你正在試圖做一些事情，如：

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

，然後是驚訝，有沒有交易。事務管理和所有其他Spring服務僅適用於應用程序上下文*中的bean。您需要以某種方式從上下文中獲取實例，而不是僅實例化一個實例。否則，您的定位器bean位於與聲明tx:annotation-driven的應用程序環境不同的應用程序環境中。

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

編輯：問題正是我所說的（第二部分）。您創建兩個應用程序上下文。你在第一個創建你的ServiceLocator，但是你只在第二個中啓用註解驅動的事務。您似乎不瞭解上下文之間的界限。通常 - 至少在我的經驗中 - 「業務」bean，就像ServiceLocator一樣，存在於根環境中，該環境由ContextLoaderListener開始，並通過contextConfigLocation進行配置。配置DispatcherServlet或由DispatcherServlet使用的控制器和其他bean位於與由該*-servlet.xml文件配置的servlet相關的另一個上下文中。這個上下文變成了根上下文的子上下文，並且其中的bean可以從根上下文注入bean，儘管反過來也是如此。

從我的角度來看，通過將tx:annotation-driven添加到與DispatcherServlet關聯的子上下文中，您已經破壞了比以前更糟糕的事情。相反，您應該確保ServiceLocator是在根環境中創建的，其中事務服務已經可用並且屬於它們所在的位置。

Answer 2

您應該簡單地重命名 「txManager」 到 「transactionManager的」。來自EnableTransactionManagement的JavaDoc：

...在XML的情況下，名稱是「transactionManager」。 <tx:annotation-driven/>被硬連接以默認尋找名爲「transactionManager」的bean ...
