解决问题 Could not obtain transaction-synchronized Session for current thread
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
解决方案
在 spring-config.xml 配置事务 切入点 和 切入方法
<!-- 配置事务管理 --> <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\" /> <!-- 配置事务的传播特性 --> <tx:advice id=\"txAdvice\" transaction-manager=\"transactionManager\"> <tx:attributes> <tx:method name=\"dispose*\" propagation=\"REQUIRED\" /> </tx:attributes> </tx:advice> <!-- 配置事务的切入点 --> <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目录下下有没有细分 service 和 impl层,必须是 schedule.*.*(..)) ,否则会报如下错误。
