Controladores no Spring Boot não funcionam

Criei um novo projeto Spring boot mais aparentemente nenhum dos mapeamentos dos controllers estão sendo carregados.

Segue arquivos:

package br.com.dome.config;

import org.springframework.context.annotation.ComponentScan;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;

import br.com.dome.controller.DomeController;

@EnableWebMvc
@ComponentScan(basePackageClasses = DomeController.class)
public class AppWebConfiguration {

}

Start da Aplicação:

package br.com.dome.config;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class DomeApplication {

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

}

Arquivo de configuração do spring (pelo que entendi nem deveria ser necessário):

package br.com.dome.config;

import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;

public class SpringConf extends AbstractAnnotationConfigDispatcherServletInitializer{

    @Override
    protected Class<?>[] getRootConfigClasses() {
        return null;
    }

    @Override
    protected Class<?>[] getServletConfigClasses() {
        return new Class[] {AppWebConfiguration.class};
    }

    @Override
    protected String[] getServletMappings() {
        return new String[] {"/"};
    }

}

Controlador principal:

package br.com.dome.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class DomeController {

    @RequestMapping("/")
    public String index() {
        System.out.println("Entrei no / DomeController");
        return "index";
    }
}

Quando inicio a aplicação não apresenta nenhum erro no console, porém se eu alterar o nome da página index.html para home.html e alterar o controlador para retornar a "home" ele da erro 404.
