Вы используете Thymeleaf, и он может разрешить индекс шаблона или дома.TemplateResolver от Thymeleaf отвечает за загрузку разметки HTML.По умолчанию он преобразует имена шаблонов, такие как home, в имена ресурсов, такие как classpath:/templates/home.html или WEB-INF/templates/home.html.

Так что вместо home.jsp попробуйте home.html.Надежда решит вашу проблему.
