Exception while handling OAuth2 callback (null). Spring Social facebook login

I have some problems with facebook login integration. Here is my Social configuration: @Configuration @EnableSocial public class SocialConfig implements SocialConfigurer { private final Logger log = LoggerFactory.getLogger(SocialConfig.class); @Inject Environment environment; @Inject ConnectionRepository customSocialConnectionRepository; @Inject SocialUserConnectionRepository socialUserConnectionRepository; @Bean public ConnectController connectController(ConnectionFactoryLocator connectionFactoryLocator) { ConnectController controller = new ConnectController(connectionFactoryLocator, customSocialConnectionRepository); controller.addInterceptor(new FacebookCustomConnectInterceptor()); return controller; } @Override public void addConnectionFactories(ConnectionFactoryConfigurer connectionFactoryConfigurer, Environment environment) { // Facebook configuration String facebookClientId = environment.getProperty("spring.social.facebook.clientId"); String facebookClientSecret = environment.getProperty("spring.social.facebook.clientSecret"); if (facebookClientId != null && facebookClientSecret != null) { log.debug("Configuration FacebookConnectionFactory"); connectionFactoryConfigurer.addConnectionFactory( new FacebookConnectionFactory( facebookClientId, facebookClientSecret ) ); } else { log.error("Cannot configure FacebookConnectionFactory id or secret null"); } } @Override public UserIdSource getUserIdSource() { return new AuthenticationNameUserIdSource(); } @Override public UsersConnectionRepository getUsersConnectionRepository(ConnectionFactoryLocator connectionFactoryLocator) { return new CustomSocialUsersConnectionRepository(socialUserConnectionRepository, connectionFactoryLocator); } } I have domain object for store SocialUserConnection.

} } and UsersConnectionRepository (http://pastebin.com/7UzsndJq) I use ConnectController to handle facebook connection, register and login user into application. public class FacebookCustomConnectInterceptor implements ConnectInterceptor<Facebook> { private final Logger log = LoggerFactory.getLogger(FacebookCustomConnectInterceptor.class);

//SecurityContextHolder.clearContext(); SecurityContextHolder.getContext().setAuthentication(authentication); } The problem is when i try to run some functions in postConnect. When i try to do this i got error: WARN 3232 --- [nio-8080-exec-3] o.s.s.connect.web.ConnectController : Exception while handling OAuth2 callback (null). Redirecting to facebook connection status page. Full stack: http://pastebin.com/QXGtv3xe I can't post more than 2 links :) I use Spring Boot 1.3.5
