Java spring не может найти зависимость

Учусь создавать web app. На офф.сайте spring нашел зависимости и попытался создать контроллер

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;
@Controller
public class Controller {
    @GetMapping("/")
    public String home(Model model) {
        model.addAttribute("main", "Main Page");
        model.addAttribute("world", "world");
        return "main";
    }
}

подсвечивает как ошибку в классе Controller запись с импортам

import org.springframework.stereotype.Controller;

Вот ошибка при выполнении
