Defining a new auto-proxy creator

[visoo]

Hi,

I would like to expose services (classes that implement an interface called Service) using RMI. I can export them one by one using RmiServiceExporter, but in order to avoid bloating the XML config I'd like to have an auto-proxy creator that automatically creates an RMI service exporter for any bean implementing the Service interface.

The manual way:

<!-- Service class -->
class MyService1 implements Service { 
... 
}

<!-- Service config in Spring -->
<bean id="MyService1Bean" class="mycompany.MyService1"/>

<!-- Publish service using RMI -->
<bean class="org.springframework.remoting.rmi.RmiServiceExporter">
	<property name="serviceInterface" value="mycompany.MyService1" />
	<property name="serviceName" value="MyService1" />
	<property name="service" ref="MyService1Bean" />
</bean>

(repeat this for each service)

How can this be replaced with a standard Spring auto proxy creating mechanism?

Thanks,
Peter

If you use Spring 2.5.x you could even define your own annotation for that. You could extend @Component or @Service and create a @RmiService annotation. Then create a BeanPostProcessor which knows what to do with it.

You might want to take a look at the CommonAnnotationBeanPostProcessor and AutowireAnnotationBeanPostProcessor for some information. Also looking at the transcational stuff (@Transactional) might clear things.
