EJB 3和Spring @Transactional

Question

对于我的EJB bean的某种原因，一个间接调用当我运行上面的设置的代码与弹簧@Transactional注解

注释一个DAO，我得到一个交易异常像下面

的事务管理我的bean定义看起来像

<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么这个问题有一些启发，我应该如何correc它呢？

Answer 1

尝试使用@TransactionAttribute(NOT_SUPPORTED)来标记您的EJB方法。但是，如果你想一起使用Spring和EJB，甚至是使用Hibernate（JPA），你应该只依赖容器服务：允许通过JBOSS引发JPA，从JNDI获得Spring的事务管理器（刚够添加<tx:jta-transaction-manager/>）等。

从其他方面来说，如果你有Spring，为什么你需要EJB？
