Answer 1

Whenever I was trying with your code I was getting org.springframework.web.servlet.PageNotFound.noHandlerFound No mapping found for HTTP request on my tomcat console and getting 404 on the browser. By changing URL pattern from /* to / solved the problem.

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