简化spring中的事务管理配置

xml代码: 

<bean id="proxyService" class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">
        <property name="transactionManager"><ref local="myTransactionManager"/></property>
        <property name="target">
                <ref local="itemService"/>
        </property>
        <property name="transactionAttributes">
            <props>
                <prop key="find*">PROPAGATION_REQUIRED,readOnly</prop>
                <prop key="add*">PROPAGATION_REQUIRED</prop>
                <prop key="update*">PROPAGATION_REQUIRED</prop>
                <prop key="delete*">PROPAGATION_REQUIRED</prop>
                <prop key="*">PROPAGATION_REQUIRED,readOnly</prop>
            </props>
        </property>
    </bean>
    <bean id="itemService" class="com.xxx.services.IServiceImpl">
        <property name="itemMasterDAO"><ref local="itemMasterDAO"/></property>
    </bean>


系统中有多个service,但我们的事务策略大部分都是一样的，难道非要每个service都要写一个这样的代理配置么?当然不是..
看下面代码:

xml代码: 


<!-- Transactional proxy for the services -->
    <bean id="baseTxProxy" lazy-init="true" class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">
        <property name="transactionManager"><ref bean="transactionManager"/></property>
        <property name="transactionAttributes">
            <props>
                                <prop key="*">PROPAGATION_REQUIRED</prop>
            </props>
        </property>
    </bean>

    <bean id="itemService" parent="baseTxProxy">
        <property name="target">
            <bean class="ItemServiceImpl" autowire="byName"/>
        </property>
    </bean>
