Custom UserDetailsService in spring-security - spring-security

Question

I cant proceed further into my project because of an strange error. I am trying to implement spring-security and spring data JPA for my application, which exposes only REST api.
Now, when I am trying to implement my custom UserDetailsService class, as mentioned below, the parameter username in method loadUserByUsername is not the username I am passing as a POST request parameter, rather its the client_id parameter.
Can someone please suggest as what am I doing wrong?
public class CustomUserDetailsService implements UserDetailsService {
private ClientDetailsService clientDetailsService;
private String emptyPassword = "";
public CustomUserDetailsService() {
}
public CustomUserDetailsService(ClientDetailsService clientDetailsService) {
this.clientDetailsService = clientDetailsService;
}
private List<GrantedAuthority> getAuthorities(String role) {
List<GrantedAuthority> authList = new ArrayList<GrantedAuthority>();
authList.add(new SimpleGrantedAuthority("ROLE_USER"));
// you can also add different roles here
// for example, the user is also an admin of the site, then you can add
// ROLE_ADMIN
// so that he can view pages that are ROLE_ADMIN specific
if (role != null && role.trim().length() > 0) {
if (role.equals("admin")) {
authList.add(new SimpleGrantedAuthority("ROLE_ADMIN"));
}
}
return authList;
}
#Override
public UserDetails loadUserByUsername(String username)
throws UsernameNotFoundException {
ClientDetails clientDetails = clientDetailsService
.loadClientByClientId(username);
String clientSecret = clientDetails.getClientSecret();
if (clientSecret == null || clientSecret.trim().length() == 0) {
clientSecret = emptyPassword;
}
return new User(username, clientSecret, clientDetails.getAuthorities());
}
}
My spring-security configuration is as following:
