Spring can you autowire inside an abstract class?

Spring is failing to autowire my object? Is it possible to autowire an object within an abstract class. Assume all schemas are supplied in application-context.xml

Question: What annotation should be on the base and extending classes (if any) @Service @Component?

Example

abstract class SuperMan {

    @Autowire
    private DatabaseService databaseService;

    abstract void Fly();

    protected void doSuperPowerAction(Thing thing) {

        //busy code

        databaseService.save(thing);

    }
}

Extending class

public class SuperGirl extends SuperMan {

    @Override
    public void Fly() {
        //busy code
    }

    public doSomethingSuperGirlDoes() {

        //busy code

        doSuperPowerAction(thing)

    }

application-context.xml

<context:component-scan base-package="com.baseLocation" />
<context:annotation-config/>

I have that kind of spring setup working

an abstract class with an autowired field

public abstract class AbstractJobRoute extends RouteBuilder {

    @Autowired
    private GlobalSettingsService settingsService;

and several children defined with @Component annotation.
