修飾子publicを持つクラスorg.springframework.aop.TruePointcutのメンバーにアクセスできません

StrutsとStruts JSONプラグインを使用してSpringアプリケーションを開発しています。アプリケーションを実行すると、（Firebugで）次のエラーが発生します。

org.Apache.struts2.json.JSONException: org.Apache.struts2.json.JSONException: org.Apache.struts2.json.JSONException: org.Apache.struts2.json.JSONException: Java.lang.IllegalAccessException: Class org.Apache.struts2.json.JSONWriter can not access a member of class org.springframework.aop.TruePointcut with modifiers public

これは完全なスタックトレースです。

このクラス自体は公開されていません。パッケージ保護されています（ ここ を参照）。メンバーにアクセスする前に、プライベートまたは保護されたメンバーにアクセスする場合とまったく同じように、setAccessible(true)を呼び出す必要があります。

編集。残念ながら、完全なスタックトレースが提供されていません。この例外があなたの活動の結果である場合（つまり、自分でSpringクラスのメンバーにアクセスしようとした場合）、解決策は上記のとおりです。ただし、フレームワークの衝突の結果としてこれが発生した場合は、詳細を送信してください。おそらく、StrutsとSpringのバージョンに互換性がないか、追加の構成が必要です。
