Question

currently I’m creating proxy classes from interfaces with spring 3 xml config like this:

<bean id="abstractDaoTarget" class="mypackage.GenericDaoImpl" abstract="true" />

<bean id="abstractDao" class="org.springframework.aop.framework.ProxyFactoryBean" abstract="true" />

<bean id="personDao" parent="abstractDao">
    <property name="proxyInterfaces">
        <value>mypackage.CustomerDao</value>
    </property>
    <property name="target">
        <bean parent="abstractDaoTarget">
        </bean>
    </property>
</bean>

Note that I have only one interface named PersonDao and NO implementation of this interface. The above xml snippet works fine, I can create an ‘instance’ of the interface.

My Question is how can I achieve this with pure Spring 3 annotations without the above xml snippet?
Is it possible without xml?

Answer 1

Are you looking for an way to generate Beans with an factory completely written in Java without xml? – Then use @Configuration to annotate the class and @Bean to annotate the method that creates the bean. 3.11.1 Basic concepts: @Configuration and @Bean

If this is not what you mean, then have a look at the code of Hades. This is a project that do the same think like (I guess) you. Creating DAOs from Interfaces.
