Spring jpa transaction business to Dao - spring

Question

business layer:
public class ServiceImpl implements Service{
#Transactional(readOnly = false)
public void createOrUpdateAppPing(String s) {
servicePingDao.createOrUpdateAppPing(s);
}
}
Dao layer
public void createOrUpdateAppPing(String sc) {
EntityManager entityManager = entityManagerFactory.createEntityManager();
pingScService(sc,entityManager);
if(ifHasPingScConfig(sc,entityManager)) {
updateScConfig(sc,entityManager);
} else {
createScConfig(sc,entityManager); }
entityManager.close();
}
here :
** pingScService has select query
** updateScConfig - update query
** createScConfig-insert
