対処した内容

mvc-config.xmlファイルがしっかり記述できていなかった

mvc-config.xml

<!-- エラー箇所のみ記載 -->

<!-- Uncomment and your base-package here:   -->
<context:component-scan base-package="jp.co.kenshu.controller"/>

ここの指定が間違えていたので、変更したらなおった

mvc-config.xml

<!-- Uncomment and your base-package here:   -->
<context:component-scan base-package="jp.co.kenshu"/>
