ContextLoaderListener versus DispatcherServlet

The o.s.web.servlet.DispatcherServlet interface specifies configuration classes to be loaded on their own using the getServletConfigClasses() method:

    //src/main/java/c/p/s/web/configuration/WebAppInitializer    public class WebAppInitializer extends         AbstractAnnotationConfigDispatcherServletInitializer {        ...        @Override        protected Class<?>[] getServletConfigClasses() {            return new Class[] { WebMvcConfig.class };        }        ...        @Override        public void onStartup(final ServletContext servletContext) throws          ServletException {            // Registers DispatcherServlet            super.onStartup(servletContext);        }    }

The DispatcherServlet class creates o.s.context.ApplicationContext, which is a child of the root ApplicationContext interface. ...
