FacebookConnectionFactory connection "https://graph.facebook.com/me"のGETリクエストで400（Bad Request）が発生しましたMissingAuthorizationException：

Question

Facebookのアプリを開発しようとしています。私はFacebookのコントローラを作成し、connectionFactoryオブジェクトを作成し、oAuth oprationsとaccessgrantオブジェクトを取得しました。私はまた、アクセストークンを得た。しかし、私は、接続

Connection<Facebook> connection = connectionFactory.createConnection(accessGrant); 

を作成しようとしたら、私はエラーを取得しています：

MissingAuthorizationException：認証が動作のために必要とされるが、APIバインディングが許可なしに作成されたが。

私はここで間違っているものを教えてください？ インスタンス化がconnectionFactoryオブジェクトに対して正しくないかどうか。

あなたがもしあれば、社会的試行は、ユーザーのすでに確立された接続を検索するため、usersConnectionRepositoryにaddConnectionする必要があり、それが認可を取得しようとauthorized.Iが試みとして、私は取得していますFacebookのオブジェクトが表示されている
