WebApplicationInitializer does not call the correct "DispatcherServlet", always returning 404

I have swtich from a spring MVC working application configured with xml configuration for java with spring loading, and I came across the following behavior. No matter which jsp page I call, I always get a 404 error. The controller hits because I see sysout messages from the controller's printer on the console, but the view is not displayed. I explicitly set the dispatcher display to "/" not "/ *", but it still does not work.

What I also see and don’t know if this is abnormal is the conclusion "There is no mapping found for the HTTP request with the URI [/WEB-INF/jsp/profile6.jsp] in the DispatcherServlet named" dispatcherServlet ""

By normal, I mean that I registered a dispatcher with the name "dispatcher" and not "dispatcherServer". It seems to me that the dispatcher is registered incorrectly, since the sysout "STARTING THE CONFIGURATION" in onStartup is also not printed. Then there is some “Servlet Manager” that is able to print sysouts from the controller, but the view was not found.

Here is the main spring boot function:

@ComponentScan("org.syncServer")
@Configuration
@EnableWebMvc
@EnableAutoConfiguration
public class Application {

public static void main(String[] args) {

ApplicationContext ctx = SpringApplication.run(Application.class, args);

System.out.println("PRINTING the beans provided by Spring Boot:");
String[] beanNames = ctx.getBeanDefinitionNames();
Arrays.sort(beanNames);
for (String beanName : beanNames) {
System.out.println(beanName);
}

}
}

Here is the initializer that extends the WebApplicationInitializer class according to the munal:

public class Initializer implements WebApplicationInitializer {

@Override
public void onStartup(ServletContext servletContext)
throws ServletException {
System.out.println("STARTING THE CONFIGURATION");
AnnotationConfigWebApplicationContext mvcContext = new AnnotationConfigWebApplicationContext();
mvcContext.register(MVCConfig.class);
mvcContext.refresh();

// Register and map the dispatcher servlet
ServletRegistration.Dynamic dispatcher = servletContext.addServlet(
"dispatcher", new DispatcherServlet(mvcContext));
dispatcher.setLoadOnStartup(1);
dispatcher.addMapping("/");
}
}

MVC Context:

@Configuration
@ComponentScan(basePackages = "org.syncServer")
@EnableWebMvc
public class MVCConfig extends WebMvcConfigurerAdapter{

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


@Bean
public InternalResourceViewResolver internalResourceViewResolver() {
InternalResourceViewResolver resolver = new InternalResourceViewResolver();
resolver.setPrefix("/WEB-INF/jsp/");
resolver.setSuffix(".jsp");
//resolver.setOrder(2);
resolver.setViewClass(JstlView.class);
return resolver;
}
}

my controller:

@Controller
public class ProfileController {

@RequestMapping(value = "/profile6", method=RequestMethod.GET)
public String profile6 (){
System.out.println("profile hellow6 has been hit");

return "profile6";

}

jsp profile page profile6
