SDN 4.0 multi labels for one @NodeEntity

Question

I have my existing @NodeEntity as below

@NodeEntity
public class Company {

@GraphId
private Long id;

private String name;

private String blah;

and the @Repository

@Repository
public interface CompanyRepository extends GraphRepository<Company> {

Company findByName(String name);

To create a new Company in neo4j, simply do

Company company = new Company();
company.setName("Company Name");
repository.save(company);

This will create a Company node in neo4j with Label Company.

However, I also want to be able create this with a different label. Instead of creating a new @NodeEntity and a new @Repository, can I use existing domain and repo with a separate label to do it?

I had google this, most answers are only applied to SDN 3.*. Some of those suggest to have a collection field annotate with @Labels, but looks like this @Labels has been removed from SDN4.0

This is a responsibility of Neo4j-OGM.

For multiple labels for the Node you should use inheritance in Java.

@NodeEntity
public abstract class DomainEntity { ... }

public class Company extends DomainObject { ... }

public class PublicCompany extends Company { ... }
