Spring Bootバージョン1.5.9アプリがビューファイルを開かない、見つからないエラー404

バージョン1.5.9（最新バージョン）のSpringBootでビューファイルを表示する際に問題が発生しました。SpringInitializrからプロジェクトを作成しました。私はインターネットでprobelmについてどこでも検索しました。いろいろ試してみましたが、ビューファイルを表示できなかったので、最後の選択肢としてここで聞いてみることにしました。

これが私の設定とコードです：

@Controller
public class LoginController {

    @RequestMapping(value="/giris", method = RequestMethod.GET)
    public ModelAndView giris(){
        ModelAndView modelAndView = new ModelAndView();
        modelAndView.setViewName("index");
        return modelAndView;
    }

}

コンソールタブで、次のログを取得します。

index.htmlファイルはsrc / main / resources / templatesフォルダーにあります。古いため非推奨であるため、「webapp / WEB-INF / views」のようなフォルダーには入れませんでした。SpringBootは私が推測するすべてを処理します。他に何ができるか提案がありますか？前もって感謝します。
