Question

由于某种原因，我的一个ejb bean间接调用了一个用spring @Transactional注释注释的DAO

当我使用上面的设置运行代码时，我得到一个如下所示的事务异常

    javax.ejb.EJBException: org.springframework.transaction.TransactionSystemException: Could not commit Hibernate transaction; nested exception is org.hibernate.TransactionException: commit failed

我对事务管理器的bean定义类似于

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

任何人都可以了解问题是什么以及我应该如何纠正它？

Answer 1

尝试使用@TransactionAttribute(NOT_SUPPORTED)标记EJB方法。

但是，如果你想一起使用Spring和EJB，甚至使用Hibernate（JPA），你应该只依赖于容器服务：允许通过JBOSS引发JPA，从JNDI获取Spring的事务管理器（刚好足以添加） <tx:jta-transaction-manager/>）等等。

另一方面，如果你有Spring，你为什么需要EJB？

EJB 3和Spring @Transactional
