Quando digito na url http://localhost:8080/casadocodigo o @Controller não identificar o arquivo home.jsp. O eclipse não imprime ENTRANDO NA CASA DO CODIGO...

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("entrando na casa do codigo");
        return "home";



    }


}
package br.com.casadocodigo.loja.conf;

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

public class ServletSpringMvc extends AbstractAnnotationConfigDispatcherServletInitializer {

    @Override
    protected Class<?>[] getRootConfigClasses() {
        // TODO Auto-generated method stub
        return null;
    }

    @Override
    protected Class<?>[] getServletConfigClasses() {
        // TODO Auto-generated method stub
        return new Class[] {AppWebConfiguration.class};
    }

    @Override
    protected String[] getServletMappings() {
        // TODO Auto-generated method stub
        return new String[] {"/"};
    }

Olá Rodrigo,

Percebi que está utilizando o wildfly como server pra aplicação. Um cuidado é que parece que o contexto onde ele disponibilizou a aplicação não é /casadocodigo que está tentando acessar.

11:56:59,062 INFO  [org.wildfly.extension.undertow] (MSC service thread 1-8) JBAS017534: Registered web context: /casadocodigo-0.0.1-SNAPSHOT

Perceba que neste trecho ele registra um contexto diferente. Dê uma olhada nisso.

Abraço!
