"org.hibernate.HibernateException: No Session found for current thread"即使方法包装在代理中

Question

我得到以下错误:

相关的spring配置:

<bean id="hibernateSessionFactory"
    class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"> <!-- annotation.AnnotationSessionFactoryBean -->
    <property name="dataSource" ref="mysqlDataSource" />
......

with NO hibernate.current_session_context_class .

<tx:annotation-driven  transaction-manager="transactionManager" /> 
<bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
    <property name="sessionFactory" ref="hibernateSessionFactory"/>
</bean>
<tx:advice id="transactionInterceptor" transaction-manager="transactionManager">
    <tx:attributes>
        <tx:method name="*" propagation="REQUIRES_NEW" rollback-for="Throwable"/>
    </tx:attributes>
</tx:advice>
<aop:config>
    <aop:advisor pointcut="execution(* com.test.jobs.*.*Job*.*_Execute(..))" advice-ref="transactionInterceptor"/>
</aop:config>

可以看到，方法被封装在代理中，仍然没有找到会话!该方法由调度程序的作业运行，而不是控制器方法，它从spring上下文获取daos等。事务等在控制器方法上工作得很好，我使用@transactional。

版本:hibernate-4.3.5, spring-4.0.4

如果要将事务管理器配置为注释驱动，则不需要下面的代码

<tx:advice id="transactionInterceptor" transaction-manager="transactionManager">
    <tx:attributes>
        <tx:method name="*" propagation="REQUIRES_NEW" rollback-for="Throwable"/>
    </tx:attributes>
</tx:advice>
<aop:config>
    <aop:advisor pointcut="execution(* com.test.jobs.*.*Job*.*_Execute(..))" advice-ref="transactionInterceptor"/>
</aop:config>

只要@Transactional(propagation= propagation . requires_new)就可以用

处理它

<tx:annotation-driven  transaction-manager="transactionManager" /> 
<bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
    <property name="sessionFactory" ref="hibernateSessionFactory"/>
</bean>

然而，我认为你可以设置(propagation= propagation . requires_new)仅在功能级别为

@Service
public class SomeService{
@Autowired
private DataSource dataSource;
@Transactional(propagation=Propagation.REQUIRES_NEW)
public void useDataSource() {
//save record
}
}
