Inheritance of proxied beans

Hello there,

I have a bean that is already proxing all my service objects so that I can manage transaction´s configuration transparently. The code below shows its configuration.

Code:

---

<!-- Transaction template for Managers, from:
                http://blog.exis.com/colin/archives/...ons-spring-11/ -->
        <bean id="txProxyTemplate" abstract="true"
                class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">
                <property name="transactionManager" ref="transactionManager" />
                <property name="transactionAttributes">
                        <props>
                                <prop key="save*">PROPAGATION_REQUIRED</prop>
                                <prop key="remove*">PROPAGATION_REQUIRED</prop>
                                <prop key="load*">PROPAGATION_REQUIRED,readOnly</prop>
                                <prop key="delete*">PROPAGATION_REQUIRED</prop>
                        </props>
                </property>
        </bean>

---

I also have a service class, called BaseManager which has some generic methods, that many use cases use. The code below is the definition of the BaseManager class.

Code:

---

        <!-- Generic manager that can be used to do basic CRUD operations on any objects  -->
        <bean id="baseManager" abstract="true" parent="txProxyTemplate">
                <property name="target">
                        <bean class="br.gov.mps.souweb.service.impl.BaseManagerImpl">
                                <property name="baseDAO" ref="baseDAO" />
                        </bean>
                </property>
        </bean>

---

The problem is sometimes it is necessary to create some specificUseCaseManagers and I would like to make them inherit from BaseManager bean AND also be proxied by my transaction bean.

How can I accomplish this?

I tried the following below, but the properties defined on the superclass, i.e., on the BaseManager class are not setted by Spring.

Code:

---

<bean id="specificUseCaseManager" parent="baseManager">
                <property name="target">
                        <bean class="br.gov.mps.souweb.service.impl.specificUseCaseManagerImpl">
                        <bean>
                                <property name="buscaDAO" ref="buscaDAO" />
                        </bean>
                </property>
                <property name="transactionAttributes">
                        <props>
                                <prop key="*">PROPAGATION_REQUIRED</prop>
                        </props>
                </property>
        </bean>
