Spring 事物手动回滚

Spring事物配置:

	<!-- 配置事务管理器 -->
	<bean id="transactionManager"
		class="org.springframework.jdbc.datasource.DataSourceTransactionManager"
		p:dataSource-ref="dataSource" />

	<!-- 启用基于注解的事务管理 -->
	<tx:advice id="txAdvice" transaction-manager="transactionManager">
		<tx:attributes>
			<tx:method name="*" propagation="REQUIRED" />
			
			<tx:method name="get*" propagation="REQUIRED" read-only="true" />
			<tx:method name="find*" propagation="REQUIRED" read-only="true" />
			
			<tx:method name="add*" propagation="REQUIRED" isolation="REPEATABLE_READ" />
			<tx:method name="update*" propagation="REQUIRED" isolation="REPEATABLE_READ" />
			<tx:method name="delete*" propagation="REQUIRED" isolation="REPEATABLE_READ" />
			<tx:method name="save*" propagation="REQUIRED" isolation="REPEATABLE_READ" />
		</tx:attributes>
	</tx:advice>
	
	<!-- 通过AOP配置提供事务增强,让service包下所有Bean的所有方法拥有事务,proxy-target-class="true"使用CGLIB代理和@AspectJ自动代理支持-->
	<aop:config proxy-target-class="true">
		<aop:pointcut expression=" execution(* com.poly..*.service..*(..))" id="serviceMethod" /> 
		<aop:advisor pointcut-ref="serviceMethod" advice-ref="txAdvice" />
	</aop:config>

Spring的事物是捕获异常来进行事物回滚,有时候我们需要根据业务逻辑来判断是否需要事物回滚。这时候我们就用到手动事物回滚了,如下:


Spring项目中事物手动回滚:

TransactionAspectSupport.currentTransactionStatus().setRollbackOnly();
