How to use

getEntity

method

in

org.keycloak.models.jpa.GroupAdapter

protected TypedQuery<GroupRoleMappingEntity> getGroupRoleMappingEntityTypedQuery(RoleModel role) {
  TypedQuery<GroupRoleMappingEntity> query = em.createNamedQuery("groupHasRole", GroupRoleMappingEntity.class);
  query.setParameter("group", getEntity());
  query.setParameter("roleId", role.getId());
  return query;
}

@Override
public Set<RoleModel> getRoleMappings() {
  // we query ids only as the role might be cached and following the @ManyToOne will result in a load
  // even if we're getting just the id.
  TypedQuery<String> query = em.createNamedQuery("groupRoleMappingIds", String.class);
  query.setParameter("group", getEntity());
  List<String> ids = query.getResultList();
  Set<RoleModel> roles = new HashSet<RoleModel>();
  for (String roleId : ids) {
    RoleModel roleById = realm.getRoleById(roleId);
    if (roleById == null) continue;
    roles.add(roleById);
  }
  return roles;
}

public static GroupEntity toEntity(GroupModel model, EntityManager em) {
  if (model instanceof GroupAdapter) {
    return ((GroupAdapter)model).getEntity();
  }
  return em.getReference(GroupEntity.class, model.getId());
}

@Override
public void grantRole(RoleModel role) {
  if (hasRole(role)) return;
  GroupRoleMappingEntity entity = new GroupRoleMappingEntity();
  entity.setGroup(getEntity());
  entity.setRoleId(role.getId());
  em.persist(entity);
  em.flush();
  em.detach(entity);
}
