How to registre user in my own database through keycloak - keycloak

Question

I have been using keycloak for a very short time. made keycloak use my own user database and it works fine.
I would like new users who register to be registered directly in my database. So I implemented the UseRegistrationProvider class which contains the addUser(RealmModel realm, String username) and removeUser(RealmModel realm, UserModel user) methods.
The problem is that in the addUser method I only have the username and I would like to have all the fields that have been filled on the registration form. How do I do?
Thanks

Answer 1

the addUser(...) method return an object implementing the UserModel. You will have to implement a UserModel adapter that enable to set the attributes you want.
See Quickstart example

Here is my code. What did i miss?
public class MyUserStorageProvider implements UserStorageProvider,
UserRegistrationProvider,
UserLookupProvider,
UserQueryProvider,
CredentialInputUpdater,
CredentialInputValidator {
private final KeycloakSession session;
private final ComponentModel model;
private final UserRepository repository;
public MyUserStorageProvider(KeycloakSession session, ComponentModel model, UserRepository repository) {
this.session = session;
this.model = model;
this.repository = repository;
}
...
#Override
public UserModel addUser(RealmModel realm, String username) {
User user = new User();
user.setUsername(username);
user.setEmail("I don't have email in addUser method");
if(repository.addUser(user))
return new UserAdapter(session, realm, model, user);
else return null;
}
}
public class UserAdapter extends AbstractUserAdapterFederatedStorage {
private final User user;
private final String keycloakId;
public UserAdapter(KeycloakSession session, RealmModel realm, ComponentModel model, User user) {
super(session, realm, model);
this.user = user;
this.keycloakId = StorageId.keycloakId(model, user.getId());
}
#Override
public String getId() {
return keycloakId;
}
#Override
public String getUsername() {
return user.getUsername();
}
#Override
public void setUsername(String username) {
user.setUsername(username);
}
#Override
public String getEmail() {
return user.getEmail();
}
#Override
public void setEmail(String email) {
user.setEmail(email);
}
#Override
public String getFirstName() {
return user.getFirstName();
}
#Override
public void setFirstName(String firstName) {
user.setFirstName(firstName);
}
#Override
public String getLastName() {
return user.getLastName();
}
#Override
public void setLastName(String lastName) {
user.setLastName(lastName);
}
}
class UserRepository {
private EntityManager em;
public UserRepository(MultivaluedHashMap<String, String> config) {
em = new JpaEntityManagerFactory(new Class[]{User.class}, config).getEntityManager();
}
...
boolean addUser(User user) {
try {
em.getTransaction().begin();
em.persist(user);
em.getTransaction().commit();
return true;
}catch(Exception e) {
return false;
}
}
}
