自分がやりたいことが可能かどうか本当にわからないので、長い投稿になることをお勧めします。自分のニーズを定義するのに問題があることさえあります。基本的には、Cookieにアクセスできるように
、すでに拡張するように依頼されました。Apache XML-RPC Serverいくつかのドキュメントを確認しました。拡張する必要のあるサービスは、公式のApacheガイドに従って作成されています。私のサービスは次のようになります（ガイドから抜粋したサンプルコード）：

package org.apache.xmlrpc.demo;
public class Calculator {
  public int add(int i1, int i2) {
    return i1 + i2;
  }
  public int subtract(int i1, int i2) {
    return i1 - i2;
  }
}

このサービスを公開するために使用するサーブレットは、標準のorg.apache.xmlrpc.webserver.XmlRpcServletであり、で実行されTomcat6ます。そうは言ってCalculatorも、Cookieからデータを取得するには、次のように変更する必要があります。

public int add(int i1, int i2) {
  Cookie[] cookies = //how to do this?
  return i1 + i2;
}

使用しているので、リクエストSpringを変更しようとしCalculatorました。Autowired

package org.apache.xmlrpc.demo;
@Configurable
@Scope("request")
public class Calculator {

  @Autowired HttpServletRequest request;
  //...
}

しかし、このようにして私は例外を取得します

web.xmlを追加して適切に構成したと確信しているのでRequestContextFilter、

実際のWebリクエストの外部でリクエスト属性を参照していますか、それとも最初に受信したスレッドの外部でリクエストを処理していますか？

例外として、XmlRpcServletが（どういうわけか）完全に分離されたスレッドで電卓サービスを実行しているように感じます。私の推測が正しければ、私のサービスでリクエストを取得する方法はありますか？そして、私の推測が間違っている場合、私は何を間違っているのですか？私の質問をよりよく評価するために、いくつかの構成ファイル（、、など）も必要web.xmlですか？spring-context.xml

私たちは、他の人や将来再び自分自身に役立つ可能性のある回避策を見つけたので、別の観点から問題を取り上げたので、私たちの解決策を参考として残しておきます。
実際にはサーブレットであることに気付いたので（なんと驚き） 、リクエストを処理XmlRpcServletする方法があるはずだと思いました。実際doPostのソースコードを見ると、があります。そのため、Cookieを読み取るメソッドを作成してオーバーライドし、すでに使用可能なサーバーオブジェクトに目的の値を保存します。XmlRpcServletdoPostCustomXmlRpcServlet

public class CustomXmlRpcServlet extends XmlRpcServlet
{

  @Override
  public void doPost(HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException{
    Cookie[] cookies = request.getCookies();
    //...
    super.doPost(request, response);
  }
  //...
  //Tough we do not have other customization, here it is possible to add additional method and/or override existing ones
}

当初の目標を達成するために数日を費やしました。その後、視点を変えるだけで、問題をクリーンで簡単な方法で解決できます。チームに参加できてうれしいです！
