Is it possible to get the ClientDetails in TokenEnhancer

Question

I've configured some additional_information in the oauth_client_details table which i need to send as a additional data in access token response.

Tried calling OAuth2AccessToken.getAdditionalInformation() which is giving empty

Also can somebody explain the use of

Map<String, Object> getAdditionalInformation() in org.springframework.security.oauth2.provider.ClientDetails

Answer 1

I ended up doing this

@Component
public class ClTokenEnhancer implements TokenEnhancer {

    private ClientDetailsService clientDetailsService;

    public ClTokenEnhancer( ClientDetailsService clientDetailsService ) {

        this.clientDetailsService = clientDetailsService;
    }

    @Override
    public OAuth2AccessToken enhance( OAuth2AccessToken accessToken, OAuth2Authentication authentication ) {

        ClientDetails clientDetails = clientDetailsService.loadClientByClientId( authentication.getOAuth2Request().getClientId() );

        ( (DefaultOAuth2AccessToken) accessToken ).setAdditionalInformation( clientDetails.getAdditionalInformation() );

        return accessToken;
    }
}
