zk + Spring 4 + websealによる事前認証

Question

私の英語ではまず申し訳ありませんが、websealでSpring Filterを設定しようとすると、私のユーザ情報で「iv-user」ヘッダから取得できますしかし、内部URLにリダイレクトするとき、私のnavegatorは "ERR_TOO_MANY_REDIRECTS" を示し、多分私の構成が悪い

してください、たぶん、いくつかの例である？、すべてに感謝... !!!

フィルタappFormacionFilterSesionは任意のパス/*で実行するように設定されています。つまり、パスhttpResponse.sendRedirect("/someUrl.zul")が実行されると、フィルタコードが再度呼び出されます。おそらく、あなたの主な状態にreq.getSession().getAttribute("username") != nullを追加する必要があります。
