Using Spring Annotations in a Custom Service Component

I am trying to use Spring Annotations in a custom component, but my beans with annotations are not found.  I am define a service factory class in my component.xml wich extends com.adobe.idp.dsc.component.support.AbstractServiceInstanceFactory.

<component xmlns="http://adobe.com/idp/dsc/component/document">

   ...

  <service-factory-class>

     ....spring.SpringServiceFactory

  </service-factory-class>

  <lifecycle-class>

  </lifecycle-class>

  <search-order>

     PARENT_LAST

  </search-order></component>

In the getBeanFactory method I create an org.springframework.context.annotation.AnnotationConfigApplicationContext and set the base package and scan.  The problem is none of my bean are in the the returned  bean factory.  I have tried setting the classloader to the ServiceConfiguration classloader but that did not help either.

Does anyone know to do this?

Thanks
