EJB 3和Spring @Transactional

Question

對於我的EJB bean的某種原因，一個間接調用當我運行上面的設置的代碼與彈簧@Transactional註解

註釋一個DAO，我得到一個交易異常像下面

的事務管理我的bean定義看起來像

<bean id="transactionManager" 
    class="org.springframework.orm.hibernate4.HibernateTransactionManager"> 
    <property name="sessionFactory"> 
     <ref bean="sessionFactory" /> 
    </property> 
</bean> 

任何人都可以扔的是什麼這個問題有一些啓發，我應該如何correc它呢？

Answer 1

嘗試使用@TransactionAttribute(NOT_SUPPORTED)來標記您的EJB方法。但是，如果你想一起使用Spring和EJB，甚至是使用Hibernate（JPA），你應該只依賴容器服務：允許通過JBOSS引發JPA，從JNDI獲得Spring的事務管理器（剛夠添加<tx:jta-transaction-manager/>）等。

從其他方面來說，如果你有Spring，爲什麼你需要EJB？
