OIDC - OAuth2AuthorizedClientService is not registering the User Principal

Hi,
I am implementing OIDC in my non-spring boot application. Below is my configuration for my OIDC client and I am trying to get the OAuth2AuthorizedClient from the OAuth2AuthorizedClientService, I am getting null. Basically the OAuth2AuthorizedClientService is not registering the client principal.
I was getting redirect to okta login page and getting redirected to my controller method after authentication with okta…

@Configuration
@EnableWebSecurity
@EnableOAuth2Client
public class ClientSecurityConfigurer extends WebSecurityConfigurerAdapter{

@Override
protected void configure(HttpSecurity http) throws Exception {
    http.authorizeRequests()
    	.antMatchers("/index/4_0/**")
    	.authenticated()
    	.antMatchers("/okta_login")
    	.permitAll()
    	.anyRequest()
    	.authenticated()
    	.and()
    	.oauth2Login()
    	.loginPage("/okta_login")
    	.clientRegistrationRepository(oktaRegistrationRepository())
    	.authorizedClientService(authorizedClientService());
}

@Bean
public OAuth2AuthorizedClientService authorizedClientService() {
	return new InMemoryOAuth2AuthorizedClientService(oktaRegistrationRepository());
}

@Bean
public ClientRegistrationRepository oktaRegistrationRepository() {
	return new InMemoryClientRegistrationRepository(this.oktaClientRegistration());
}
private ClientRegistration oktaClientRegistration() {
	return ClientRegistration.withRegistrationId("okta").clientId("client id *********")
			.clientSecret("client secret ********")
			.clientAuthenticationMethod(ClientAuthenticationMethod.BASIC)
			.authorizationGrantType(AuthorizationGrantType.AUTHORIZATION_CODE)
			.redirectUriTemplate("http://localhost:9088/myApp/login/oauth2/code/okta")
			.scope("openid", "profile", "email", "address", "phone")
			.authorizationUri("https://myorg.oktapreview.com/oauth2/default/v1/authorize")
			.tokenUri("https://myorg.oktapreview.com/oauth2/default/v1/token")
			.userInfoUri("https://myorg.oktapreview.com/oauth2/default/v1/userinfo")
			.userNameAttributeName(IdTokenClaimNames.SUB)
			.jwkSetUri("https://myorg.oktapreview.com/oauth2/default/v1/keys").clientName("Okta")
			.build();
    	}	
 }

initializer:

public class ClientSecurityInitializer extends AbstractSecurityWebApplicationInitializer {
	    public ClientSecurityInitializer() {
	        super(ClientSecurityConfigurer.class);
	    }
}

okta login page:

@Controller
public class LoginController {

@RequestMapping(value="/okta_login")
public String oktaLogin(){
	return "redirect:/oauth2/authorization/okta";
	}
}

my app controller:

@Controller
@RequestMapping("/index/4_0")
public class ClientController_4_0 {

@Autowired
private OAuth2AuthorizedClientService authorizedClientService;

@RequestMapping(value = "/client", method = RequestMethod.GET)
private String getIndex(Model model, HttpServletRequest req, OAuth2AuthenticationToken authentication) {
	OAuth2AuthorizedClient authorizedClient = this.getAuthorizedClient(authentication);
	OAuth2AccessToken token = (OAuth2AccessToken) authorizedClient.getAccessToken();
	String tokenValue = token.getValue();
	return "v4_0/client";
}

private OAuth2AuthorizedClient getAuthorizedClient(OAuth2AuthenticationToken authentication) {
	return this.authorizedClientService.loadAuthorizedClient(
		authentication.getAuthorizedClientRegistrationId(), authentication.getName());
}

}
i am getting null here

 OAuth2AuthorizedClient authorizedClient = this.getAuthorizedClient(authentication);

I autowired the OAuth2AuthorizedClientService , where the auhtorizedClients were null, but the clientRegistrationRepository is getting loaded, as I loaded it from configuration… guess after authenticated, the client principal is not getting loaded as authorizedClients…

not sure of where I am doing wrong…any suggestion would greatly appreciated.

I figured it out… the issue is related to my SecurityInitializer class. As my app is already a Spring app (not spring boot), I don’t need to load my SecurityConfig class in it. So my Security Initializer class will be as below…

public class ClientSecurityInitializer extends AbstractSecurityWebApplicationInitializer {
}
