Lombok subclass constructor @Autowired

Question

I have superclass:

@AllArgsConstructor
public abstract class AbstractSuperService {
     protected final SuperRepository superRepository;
  
}

And two subclass:

@Service
public class OneSubService extends AbstractSuperService {
     private final OneRepository oneRepository;
     
     public OneSubService(SuperRepository superRepository, OneRepository oneRepository){
         super(superRepository);
         this.oneRepository = oneRepository;
    }
}


@Service
public class SecondSubService extends AbstractSuperService {
     private final SecondRepository secondRepository;

     public SecondSubService(SuperRepository superRepository, SecondRepository secondRepository){
         super(superRepository);
         this.secondRepository = secondRepository;
    }
}

This code is work. But if I change code: delete constructor in subclasses and add annotation lombok @SuperBuilder in all class.

@AllArgsConstructor
@SuperBuilder
public abstract class AbstractSuperService {
     protected final SuperRepository superRepository;
  
}

@Service
@SuperBuilder
public class OneSubService extends AbstractSuperService {
     private final OneRepository oneRepository;
     
}


@Service
@SuperBuilder
public class SecondSubService extends AbstractSuperService {
     private final SecondRepository secondRepository;

}

The following error appears:

Description:

Parameter 0 of constructor in OneSubService required a bean of type 'OneSubService$OneSubServiceBuilder' that could not be found.


Action:

Consider defining a bean of type 'OneSubService$OneSubServiceBuilder' in your configuration.

How to correctly apply the lombok annotation in subclass, so as not to write constructor in subclass?

If you use @SuperBuilder, no constructor is created. In Spring in order to inject OneRepository and SuperRepository, you need a constructor having these two objects as parameters.

Using @AllArgConstructor, Lombok creates the constructor just for the members of that class, not considering the super class. Why? You can read the answer of a Lombok developer here.

In the end, your first solution is a unique solution if you want to have a super class.
