 import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.Controller;
import org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping;

 public class HelloController implements Controller{

 @Override
public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response) throws Exception {
//ControllerClassNameHandlerMapping
String name=request.getParameter("name");
Map m=new HashMap();
