Spring与Spring MVC事务配置及对比

<!-- 配置Spring的事务管理器 -->
<bean id="transactionManager"
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource" />
</bean>

<!-- 注解方式配置事物 -->
<tx:annotation-driven transaction-manager="transactionManager" />
<!-- 可以配置多个,针对不同的数据源 -->
<!-- <tx:annotation-driven transaction-manager="transactionManager2" /> -->

<!-- 拦截器方式配置事物 -->
<tx:advice id="transactionAdvice" transaction-manager="transactionManager">
<tx:attributes>
<!-- 任何 RuntimeException 将触发事务回滚，但是任何 checked Exception 将不触发事务回滚 -->
<tx:method name="*" propagation="REQUIRED" read-only="false"
rollback-for="java.lang.Exception" />
<tx:method name="find*" propagation="SUPPORTS" />
<tx:method name="get*" propagation="SUPPORTS" />
<tx:method name="select*" propagation="SUPPORTS" />
</tx:attributes>
</tx:advice>
<aop:config>
<!-- 针对对应包下的所有方法 -->
<!-- <aop:pointcut id="transactionPointcut" expression="execution(* com.aa.web..service.*.*(..))" /> -->
<!-- com.aa下所有包和子包的有方法 -->
<aop:pointcut id="transactionPointcut" expression="execution(* com.aa..*.*(..))" />
<aop:advisor pointcut-ref="transactionPointcut"
advice-ref="transactionAdvice" />
<!-- 针对不同数据源或者不同的事务配置方式 -->
<!-- <aop:advisor pointcut-ref="transactionPointcut"
advice-ref="transactionAdvice2" /> -->
</aop:config>

<!-- 管理spring对象 -->
