ServletContextリソースで定義された「org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping＃0」という名前のBeanの作成エラー

問題：

クラスでメソッドを実行するためのポイントカットを作成しています。このクラスはコントローラークラスであり、アノテーション@Controllerによって示されるため、アスペクトで必要とされるものにBeanは必要ありません。 dispathcherサーブレットコード、アスペクト、およびコントローラークラスを添付しています。誰かが問題を特定できますか。

これは、Spring AOPの制限です。 AspectJポイントカットを使用してアスペクトをBeanに織り込むと、SpringはCGLIBを使用してターゲットのサブクラスを生成し、そのサブクラスからアスペクトを呼び出します。

ただし、ターゲットクラスにパブリックデフォルトコンストラクターがない場合、これは失敗します。 CGLIBにはこれを処理する機能がありますが、これはすべてSpring AOPの背後に隠されており、その動作を変更することはできません。

コンストラクターインジェクションではなく、コントローラーにセッターインジェクションを使用することに戻ることをお勧めします。理想的ではありませんが、他の回避策は考えられません。
