#### 一、问题现象 ####

在使用Hibernate的项目中，在一个定时任务中，执行某段代码，满足条件后，更新表数据。

程序在执行到更新表数据的时候，报错如下：

Could not obtain transaction-synchronized Session for current thread

#### 二、解决方案 ####

在 ***spring-config.xml*** 配置事务 **切入点** 和 **切入方法**

<bean id="transactionManager" class="org.springframework.orm.hibernate5.HibernateTransactionManager">
            <property name="sessionFactory" ref="sessionFactory" />
        </bean>
        
        
         <aop:aspectj-autoproxy proxy-target-class="true" />
        
        <tx:advice id="txAdvice" transaction-manager="transactionManager">
            <tx:attributes>
                <tx:method name="dispose*" propagation="REQUIRED" />
            </tx:attributes>
        </tx:advice>
    
        
        <aop:config>
            <aop:pointcut id="targetMethodSchedule" expression="execution(* com.miracle.luna.mock.schedule.*.*(..))" />
            <aop:advisor advice-ref="txAdvice" pointcut-ref="targetMethodSchedule" />
        </aop:config>

> **\[说明\]**  
> 1、<tx:method name=“dispose\*” propagation=“REQUIRED” /> 表示对dispose 开头的方法有效；  
> 2、<aop:pointcut id=“targetMethodSchedule” expression=“execution(\* com.miracle.luna.mock.schedule.*.*(…))” /> 可以模糊匹配 schedule 目录下的多个服务层。
> 
> 注意此处，不管schedule目录下有没有细分 service 和 impl层，必须是 schedule.*.*(…)) ，否则会报如下错误。
