Abstract Bean definition causing View Resolving Error
I am using some of the example config from the petclinic sample app. In particular I am having problems with my views resolving when I have the following bean definition:
Code:
<bean id="baseTransactionProxy" class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean"
abstract="true">
<property name="transactionManager"><ref bean="transactionManager"/></property>
<property name="transactionAttributes">
<props>
<prop key="get*">PROPAGATION_REQUIRED,readOnly</prop>
<prop key="find*">PROPAGATION_REQUIRED,readOnly</prop>
<prop key="load*">PROPAGATION_REQUIRED,readOnly</prop>
<prop key="store*">PROPAGATION_REQUIRED</prop>
</props>
</property>
</bean>
As the example shows, I am using this as the parent bean for my Transaction definitions for target business objects.
My problem is I get the following error when VelocityView tries to resolve my view:
Code:
org.springframework.beans.factory.BeanIsAbstractException: Tried to instantiate abstract bean definition '&baseTransactionProxy'

I think this has to do with org.springframework.transaction.interceptor.Transa ctionProxyFactoryBean being a FactoryBean and getBeansOfType tries to actually get the Factory. I thought that getBeansOfType would always skip Abstract beans reguardless?
Why this doesn't fail for the sample app, I have no idea unless the view resolver it's using is implemented differently. I haven't had a lot of time to look at the implementation there.
This is with Spring 1.1 Final running on Tomcat. Any ideas?
Thanks,
Patrick
