ディスパッチャーサーブレットを追加する<mvc:default-servlet-handler/>と、問題が修正されました

まず、Dispatcher Servlet を確認します。それもチェックすると、簡単な方法です。ビルドパスで外部jarを追加する必要はありません。フォルダーごとにプロジェクトワークスペースに移動し、ダウンロードした jar を直接コピーして次の場所に貼り付けます。

WebContent>WEB-INF>lib>(here directly paste your jar files.)

-> stop your application server (like tomcat);
-> go to your IDE -> Select Project -> Clean Project builds

その後、次の手順に進みます。プロジェクトを実行します。うまくいくことを願っています！
