No Spring WebApplicationInitializer types detected on classpath | Spring MVC I: Criando aplicações web

Aula: 01

Problema: Quando subo o servidor estou com o erro "No Spring WebApplicationInitializer types detected on classpath" no console, por causa deste problema acredito que o spring não esteja atendendo as requisições, pois ao acessar localhost:8080/casadocodigo recebo erro 404.

Obs: Revisei todo o processo da video aula para ver se não estava deixando passar algum passo importante mas acredito que esteja tudo correto.

ServletSpringMVC.java

package br.com.casadocodigo.loja.conf;

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

public class ServletSpringMVC extends AbstractAnnotationConfigDispatcherServletInitializer{

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

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

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

AppWebConfiguration.java

package br.com.casadocodigo.loja.conf;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.view.InternalResourceViewResolver;

@EnableWebMvc
@Configuration
@ComponentScan(basePackageClasses={HomeController.class})
public class AppWebConfiguration {

    @Bean
    public InternalResourceViewResolver internalResourceViewResolver() {
        InternalResourceViewResolver resolver = new InternalResourceViewResolver();
        resolver.setPrefix("/WEB-INF/views/");
        resolver.setSuffix(".jsp");
        return resolver;
    }
}

HomeController.java

package br.com.casadocodigo.loja.controllers;

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

@Controller
public class HomeController {

    @RequestMapping("/")
    public String index() {
        System.out.println("[HomeController:index] Start");
        return "home";
    }
}
