How can I refactor this method? (spring + java8) - spring

Question

I am trying to refactor the Java class below. I have a method that saves a POJO (entity) depending on which instance it belongs to.
The code below shows only 3 services but there is 13 service in total.
Each service is calling a separate *RepositoryImpl.
For instance, the ActiviteService is an interface and the activiteService.create(activity) will call the implementation of that interface.
#Autowired
private ActiviteService activiteService;
#Autowired
private AdresseMsSanteService adresseMsSanteService;
#Autowired
private AttributionParticuliereService attributionParticuliereService;
private boolean sauvegarder(Object object, Long idIdPlay, String game,
Integer gameIndex) {
boolean isSaved = false;
if (idIdPlay == null) {
throw new IllegalArgumentException("IdPlay id is null");
}
if (object instanceof Activite) {
Activite activite = (Activite) object;
activite.setIdIdPlay(idIdPlay);
if (this.isGameOn(activite, game, gameIndex)) {
activiteService.create(activite);
isSaved = true;
}
} else if (object instanceof AdresseMsSante) {
AdresseMsSante adresseMsSante = (AdresseMsSante) object;
adresseMsSante.setIdIdPlay(idIdPlay);
if (this.isGameOn(adresseMsSante, game, gameIndex)) {
adresseMsSanteService.create(adresseMsSante);
isSaved = true;
}
} else if (object instanceof AttributionParticuliere) {
AttributionParticuliere attributionParticuliere = (AttributionParticuliere) object;
attributionParticuliere.setIdIdPlay(idIdPlay);
if (this.isGameOn(attributionParticuliere, game, gameIndex)) {
attributionParticuliereService.create(attributionParticuliere);
isSaved = true;
}
} else if

Firstly, I would create an interface representing your Game Entity. For instance:
public interface GameEntity {
void setIdIdPlay(Long idIdPlay);
}
After that, you create the classes that implement the GameEntity interface:
#Entity
#Table
public class AdresseMsSante implements GameEntity {
#Id
Long idIdPlay;
public void setIdIdPlay(Long idIdPlay) {
this.idIdPlay = idIdPlay;
}
}
#Entity
#Table
public class Activite implements GameEntity {
#Id
Long idIdPlay;
public void setIdIdPlay(Long idIdPlay) {
this.idIdPlay = idIdPlay;
}
}
Then, create your generic repository which will save every Game Entity.
#Repository
public class Repo {
#Autowired
EntityManager entityManager;
#Transactional
public void save(GameEntity obj) {
entityManager.merge(obj);
}
}
Finally, your method will be like that:
#Autowired
Repo repo;
private boolean sauvegarder(Object object, Long idIdPlay, String game,
Integer gameIndex) {
boolean isSaved = false;
if (idIdPlay == null) {
throw new IllegalArgumentException("IdPlay id is null");
}
GameEntity gameEntity = (GameEntity) object;
gameEntity.setIdIdPlay(idIdPlay);
if(this.isGameOn(gameEntity, game, gameIndex)) {
repo.save(gameEntity);
isSaved = true;
}
return isSaved;
}
boolean isGameOn(GameEntity gameEntity, String game, Integer gameIndex) {
// do something
return true;
}
