круговая дорожка в весенней загрузке

Question

Я пытаюсь создать простое веб-приложение с использованием весенней загрузки. MVC Мой контроллер выглядит следующим образом:

@Controller
public class ControllerHome {
@RequestMapping("/")
    String getHome() {
        return "home";
    }
}

, а основной класс приложения выглядит следующим образом:

@SpringBootApplication
public class Demo4Application {
    static void main(String[] args) {
        SpringApplication.run(Demo4Application.class, args);
    }
}

и я использую следующую структуру в проекте: структура проекта

, но когда я запускаю приложение, я получаю следующую ошибку:

javax.servlet.ServletException: Circular view path [error]: would dispatch back to the current handler URL [/error] again. Check your ViewResolver setup! (Hint: This may be the result of an unspecified view, due to default view name generation.)
