StrutsとStrutsJSON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、次のエラーが発生します（Firebugの場合）。

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

これはフル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。パッケージで保護されています（ここを参照）。setAccessible(true)プライベートメンバー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、メンバーにアクセスする前に電話をかける必要があります。

編集。残念ながら、完全なスタックトレースを提供していません。この例外がアクティビティの結果である場合（つまり、Springクラスのメンバーに自分でアクセスしようとしている場合）、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。
