解決問題 Could not obtain transaction-synchronized Session for current thread

問題現象

在使用Hibernate的專案中，在一個定時任務中，執行某段程式碼，滿足條件後，更新表資料。

程式在執行到更新表資料的時候，報錯如下：

Could not obtain transaction-synchronized Session for current thread

解決方案

在 spring-config.xml 配置事務 切入點 和 切入方法

    <!-- 配置事務管理 -->
    <
 
bean id="transactionManager" class="org.springframework.orm.hibernate5.HibernateTransactionManager">
        <property name="sessionFactory" ref="sessionFactory" />
    </bean>
    
    <!-- 指定使用cglib -->
     <aop:aspectj-autoproxy proxy-target-class="true" />
    <!-- 配置事務的傳播特性 
 
-->
    <tx:advice id="txAdvice" transaction-manager="transactionManager">
        <tx:attributes>
            <tx:method name="dispose*" propagation="REQUIRED" />
        </tx:attributes>
    </tx:advice>

    <!-- 配置事務的切入點 -->
    <aop:config>
        <
 
aop:pointcut id="targetMethodSchedule" expression="execution(* com.miracle.luna.mock.schedule.*.*(..))" />
        <aop:advisor advice-ref="txAdvice" pointcut-ref="targetMethodSchedule" />
    </aop:config>

[說明]

1、<tx:method name="dispose*" propagation="REQUIRED" /> 表示對dispose 開頭的方法有效

2、<aop:pointcut id="targetMethodSchedule" expression="execution(* com.miracle.luna.mock.schedule.*.*(..))" /> 可以模糊匹配 schedule 目錄下的多個服務層

注意此處，不管schedule目錄下下有沒有細分 service 和 impl層，必須是 schedule.*.*(..)) ，否則會報如下錯誤。
