spring - Spring Social - ConnectController からメソッドをオーバーライドする方法はありますか?

Question

私が達成しようとしているのは、セッションが利用できない場合にサービスプロバイダーに接続しようとするときです.クライアントはブラウザーではなくHttpClientであるため、1つと2つを作成します。

ConnectController から直接拡張しようとしましたが、舞台裏で多くのことが起こっていると思われるため、エラーが正確に何を示しているのかはっきりしません:

  @Controller
@RequestMapping("/connect")
public class MyConnectController extends ConnectController {

    @Inject
    public MyConnectController(
            ConnectionFactoryLocator connectionFactoryLocator,
            ConnectionRepository connectionRepository) {
        super(connectionFactoryLocator, connectionRepository);
        // TODO Auto-generated constructor stub
    }

    @RequestMapping(value = "/{providerId}", method = RequestMethod.GET)
    public String get(@PathVariable String providerId, NativeWebRequest request) {
        return "I'll return a json string here, OK?";
    }

    @Override
    @RequestMapping(value = "/{providerId}", method = RequestMethod.POST)
    public RedirectView connect(@PathVariable String providerId,
            NativeWebRequest request) {
        System.out.println("I'll create a new session here, OK?");
        return super.connect(providerId, request);
    }
}
