@EnableWebMvc  
public class MvcConfig extends WebMvcConfigurerAdapter {  


    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
       registry.addResourceHandler("/resources/**").addResourceLocations("/resources/");
    }

    @Override

       configurer.enable();
    }

//  JSP VIEW-RESOLVER

    public InternalResourceViewResolver jspViewResolver() {
       InternalResourceViewResolver bean = new InternalResourceViewResolver();
       bean.setOrder(0);
       bean.setPrefix("/WEB-INF/html/");
       bean.setSuffix(".html");
       return bean;
    }

}

My Root Config class

@Configuration
@ComponentScan(basePackages = {"controller"})
@Import({MvcConfig.class})
public class RootConfig {

}

my initializer class

public class InitrMvc implements WebApplicationInitializer{

    @Override
    public void onStartup(ServletContext container) throws ServletException {        

        // Create the 'root' Spring application context
        AnnotationConfigWebApplicationContext rootContext = new AnnotationConfigWebApplicationContext();
        rootContext.register(RootConfign.class);

        // Manage the lifecycle of the root application context
        container.addListener(new ContextLoaderListener(rootContext));

        // Create the dispatcher servlet's Spring application context
        AnnotationConfigWebApplicationContext dispatcherServlet = new AnnotationConfigWebApplicationContext();
        dispatcherServlet.register(MvcConfig.class);

        // Register and map the dispatcher servlet
        ServletRegistration.Dynamic dispatcher = container.addServlet("dispatcher", new DispatcherServlet(dispatcherServlet));
        dispatcher.setLoadOnStartup(0);
        dispatcher.addMapping("/");
    }
}

and my controller class

@Controller public class IncidenciaControlador {

@RequestMapping(value = "login/testPage", method = RequestMethod.GET)
   public String login(Model model) {



       return "login/testPage";
   }

}

and my project tree structure

MyProjectMavenWeb
  --Web Pages
      --WEB-INF
          --htmlPages
              --login
                 --testPage.html
          --resources (at the same level as htmlPages)
             --img
                logo.png
