Spring事务回滚的实现

spring关于事务回滚的配置

<bean name="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">           <property name="dataSource" ref="dataSource"></property>    </bean>    <aop:config>        <aop:pointcut id="pc" expression="execution(* com.web.service.*.*(..))" />        <aop:advisor pointcut-ref="pc" advice-ref="txAdvice" />    </aop:config>    <tx:advice id="txAdvice" transaction-manager="transactionManager">        <tx:attributes>            <tx:method name="create*" propagation="REQUIRED" rollback-for="java.lang.RuntimeException" isolation="DEFAULT"/>            <tx:method name="insert*" propagation="REQUIRED" rollback-for="java.lang.RuntimeException" isolation="DEFAULT"/>            <tx:method name="add*" propagation="REQUIRED" rollback-for="java.lang.RuntimeException" isolation="DEFAULT"/>            <tx:method name="save*" propagation="REQUIRED" rollback-for="java.lang.RuntimeException" isolation="DEFAULT"/>            <tx:method name="modify*" propagation="REQUIRED" rollback-for="Exception" isolation="DEFAULT"/>            <tx:method name="update*" propagation="REQUIRED" rollback-for="Exception" isolation="DEFAULT"/>            <tx:method name="delete*" propagation="REQUIRED" rollback-for="Exception" isolation="DEFAULT"/>        </tx:attributes>    </tx:advice>

我们要根据配置中配置的rollback-for捕获抛出的异常进行回滚，否者回滚将会失败；还要注意回滚路径是否正确，如上例中为com.web.service，另外如果使用mysql数据库则在建表时要选择Innodb，因为这种连接方式支持回滚。
