How to rewrite Spring beans service by name using only annotations

Question

Given that I have a Spring bean configured as

@Service("myService")
public class DefaultService extends MyService {
}

and class using this bean

public class Consumer {
    @Autowired
    @Qualifier("myService")
    private MyService service;
    ...
}

Now I want my project, including the previous classes, to have the Consumerfollowing implementation MyService. So I would like to rewrite beanMyService

@Service("myService")
public class SpecializedService implements MyService {
}

resulting in Consumertransferring the instance SpecializedServiceinstead DefaultService. By definition, I cannot have two beans with the same name in a Spring container. How can I tell spring that the definition of a new service should rewrite the older one? I do not want to change the class Consumer.
