問題描述

1.spring事務不會回滾，網上的方法都試過了，沒有效果。2.配置如下：

<context:component-scan base-package='com.szcshl'><context:exclude-filter type='annotation' expression='org.springframework.stereotype.Controller'/> </context:component-scan>2.springmvc.xml

<context:component-scan base-package='com.szcshl' use-default-filters='false'><context:include-filter type='annotation' expression='org.springframework.stereotype.Controller'/> </context:component-scan>3.spring-hibernate.xml

<!-- 配置事務管理器 --> <bean name='transactionManager' class='org.springframework.orm.hibernate4.HibernateTransactionManager'><property name='sessionFactory' ref='sessionFactory'></property> </bean> <!-- 注解方式配置事物 --> <!-- <tx:annotation-driven transaction-manager='transactionManager' /> --> <!-- 攔截器方式配置事物 --> <tx:advice transaction-manager='transactionManager'><tx:attributes> <tx:method name='add*' /> <tx:method name='save*' /> <tx:method name='update*' /> <tx:method name='modify*' /> <tx:method name='edit*' /> <tx:method name='delete*' /> <tx:method name='remove*' /> <tx:method name='repair' /> <tx:method name='deleteAndRepair' /> <tx:method name='get*' propagation='SUPPORTS' read-only='true' /> <tx:method name='find*' propagation='SUPPORTS' read-only='true' /> <tx:method name='load*' propagation='SUPPORTS' read-only='true' /> <tx:method name='search*' propagation='SUPPORTS' read-only='true' /> <tx:method name='datagrid*' propagation='SUPPORTS' read-only='true' /> <tx:method name='*' propagation='SUPPORTS' read-only='true' /></tx:attributes> </tx:advice> <aop:config><aop:pointcut expression='execution(* com.szcshl.service..*Impl.*(..))' /><aop:advisor pointcut-ref='transactionPointcut' advice-ref='transactionAdvice' /> </aop:config>4.controller

問題解答

看了看，你對service接口進行事務管理，而不是controller你拋出異常是在controller，當然不會事務回滾啦

你試試在sevice實現類中，save一下，再拋個異常，看看save成功不成功

ps一下:mysql有兩個存儲引擎(常用),一個是InnoDB一個是MyISAM,前者支持行級鎖，事務，外鍵，后者不支持

樓上說的沒錯，spring事務作用于service層，當遇到service方法拋出異常時，事務將回滾。所以你的正確測試實踐應該是在service層方法中拋出異常。
