How can I get user's logged Id from SecurityContextHolder using Spring Social? - spring

Question

So, how can I get the user's id from a current logged user from any social providers?
Well I know I can build a custom SocialUser, the same I do for User, but in the case there is no getter on SocialUserDetails and the method I got just accepts userDetails, instead of a normal "Person" entity.
public class SocialUsersDetailServiceImpl implements SocialUserDetailsService {
private UserDetailsService service;
public SocialUsersDetailServiceImpl(UserDetailsService service) {
this.service = service;
}
#Override
public CSocialUserDetails loadUserByUserId(String username) throws UsernameNotFoundException, DataAccessException {
UserDetails userDetails = (UserDetails) service.loadUserByUsername(username);
return new CustomSocialUser(userDetails.getUsername(), userDetails.getPassword(), userDetails.getAuthorities(), userDetails.getUserIdentifier()??);
}
}
But there is no ".getUserIdentifier()" method on UserDetails, there is some workaround for this?
The way I do for User:
#Service
public class UserDetailsServiceImpl implements CUserDetailsService {
#Resource
private PersonRepository respository;
#Override
public CUserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
Person p = repository.findByUsername(username);
return new CUser(p.getUsername(), p.getPassword(), p.grantedAuthorities(), p.getIdPerson());
}
}
and the CUser:
public class CUser extends User{
private Number identifier;
public CUser(String username, String password, Collection<? extends GrantedAuthority> authorities, Number identifier) {
super(username, password, authorities);
this.identifier = identifier;
}
public Number getUserIdentifier() {
return identifier;
}
}
