While reading a few great articles (http://www.intertech.com/Blog/spring-4-generic-qualifiers/ comes to mind) I noticed that Spring 4 supports injecting generic objects if their type is provided when defining @beans. I'm trying to figure out how I can do that when describing beans in a BeanDefinitionRegistryPostProcessor

Consumer.java

public class Consumer{
  // these work with qualifiers...
  
  @Inject
  private GenericService<User, Long> userService;
  
  @Inject
  private GenericService<Organization, Long> orgService;
}

GenericService.java

public class GenericService<E, ID>{
  // ... 
}

Processor.java

public class Processor extends InstantiationAwareBeanPostProcessorAdapter
        implements BeanDefinitionRegistryPostProcessor{
  
  // ...
  @Override
  public void postProcessBeanDefinitionRegistry(BeanDefinitionRegistry r) throws BeansException {
        AbstractBeanDefinition service = BeanDefinitionBuilder.rootBeanDefinition(GenericService.class)
                .getBeanDefinition();
        
        r.registerBeanDefinition(service, "userService" );
        // how do I hint that this bean has the bound types <User, Long> ??
        AbstractBeanDefinition service2 = BeanDefinitionBuilder.rootBeanDefinition(GenericService.class)
                .getBeanDefinition();
        // how do I hint that this bean has the bound types <Organization, Long> ??
        r.registerBeanDefinition(service2, "orgService" );
    }

}
