[SpringBoot]jspで作成した画面が表示されない

前提・実現したいこと

今までテンプレートは、Thymeleafを使用してきたのですが、
一度、jspを使用して簡易的なプロジェクトを作成することになりました。
そこで、画面をjspで作成し、stsで実行したときには期待通りの画面が表示されたのですが、
jarファイルを作成、コマンドプロンプトにて実行しても404エラーが出てしまい、表示されませんでした。
実行時に出た処理(?)も見てみたのですが、エラーが出ている様子もなく・・・
色々調べてみたのですが、中々それらしい結果を得ることが出来ず質問させて頂きました。

原因がわかる方がいらっしゃいましたら、どうかご教授お願いします。
jspに関しての知識がゼロの状態に等しい為、訳のわからない事を言ってしまっているかもしれません・・・
その時はご指摘お願いします。
また、不足している情報等ございましたら、お知らせください。
