How I can get current user's email from keycloak in jhipster - spring-security

Question

I configured jhipster with ouath 2.0 that use keycloak as the authorization server. But How I can get the current user's email in my app?

Answer 1

When a user logs in via OAuth2, the account is synchronized to the local user database.
In your application exists SecurityUtils.java which has a method to get the current user's login. You can get the login and query for the user/email.
String login = SecurityUtils.getCurrentUserLogin().orElse("anonymoususer");
Optional<User> optionalUser = userService.getUserWithAuthoritiesByLogin(login);
if (optionalUser.isPresent()) {
String email = optionalUser.get().getEmail();
}

Answer 2

One way is to use the AccountService
In your component, you would do something like shown below. You will need to change the values to match your project
// Add these imports
import { AccountService } from 'app/core/auth/account.service';
import { Account } from 'app/core/auth/account.model';
#Component({
selector: 'jhi-pm-your-project-update',
templateUrl: './pm-your-project-update.component.html',
})
export class YourUpdateComponent implements Oninit{
// Add this varable to store the account information
account: Account | null = null;
constructor(
protected dataUtils: DataUtils,
protected eventManager: EventManager,
protected yourService: YourService,
protected activatedRoute: ActivatedRoute,
protected accountService: AccountService
){}
ngOnInit(): void {
this.accountService.identity().subscribe(account => (this.account = account));
}
save(): void {
// Here is how to access the email
yourEntity.lastModifiedBy = this.account?.email;
}
}
