Hello. I am writing a simple mvc application on Spring Boot. I've run into a problem that I can't find a solution for. Please help.
All three mvc modules are written in the project. Problems arise with view.
There is a controller

@RequestMapping(value = "/", method = RequestMethod.GET)
    public String homePage() {
        return "hello";
    }

There is a tuner

@Configuration
@EnableWebMvc
public class AppConfiguration extends WebMvcConfigurerAdapter {

    @Override
    public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
        configurer.enable();
    }

    @Bean
    public InternalResourceViewResolver viewResolver() {
        InternalResourceViewResolver resolver = new InternalResourceViewResolver();
        resolver.setViewClass(org.springframework.web.servlet.view.JstlView.class);
        resolver.setPrefix("/WEB-INF/");
        resolver.setSuffix(".jsp");
        return resolver;
    }

//    @Override
//    public void addResourceHandlers(ResourceHandlerRegistry registry) {
//        registry.addResourceHandler("/WEB-INF/").addResourceLocations("/css/");
//    }

    @Bean
    public FilterRegistrationBean filterRegistrationBean() {
        FilterRegistrationBean registrationBean = new FilterRegistrationBean();
        CharacterEncodingFilter characterEncodingFilter = new CharacterEncodingFilter();
        characterEncodingFilter.setEncoding("UTF-8");
        registrationBean.setFilter(characterEncodingFilter);
        return registrationBean;
    }
}

/src/main/webapp/WEB-INF/ contains hello.jsp

<html>
<head>
    <title>Title</title>
</head>
<body>
<h1>Success!!!</h1>
</body>
</html>

Crashes when starting a project

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).
/WEB-INF/hello.jsp

I found numerous complaints about this message on the Internet, but not a single solution suited me.
My version of why this happens is that spring cannot display the jsp page because it cannot find it. I don't know how else they (page and spring) can be aggregated, except by using the customizer.
What can be tried in my situation?
