Why can't Spring Boot see html?

Question

Spring

Downloaded from https://start.spring.io/ project from Web, JPA. I deploy on my computer. Next, I throw the index.html file into the src/main/resources/static folder. I start the project - the page is displayed. Now, I am adding a controller

package ru.nevars.bunny.web.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;

@Controller
@RequestMapping(value = "/page-login")
public class LoginController {

    @RequestMapping(value = "/", method = RequestMethod.GET)
    public ModelAndView loadLoginPage() {
        return new ModelAndView("page-login");
    }
}

And I throw page-login.html into the static folder. When launching a varnik on a tomcat, the following error is thrown

Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Not Found, status=404).
no message available

How is this problem treated in Spring Boot?
PS I tried to add a custom path to the static folder in application.properties. I also tried to put the html of the page in another folder and set the path to it in the spring properties.
