Spring MVC using ParameterizableViewController

-----------------------------------------------
----------------------------------------------------------
Create HelloController class and extends ParameterizableViewController so that we can pass dynamically View(jsp) name through xml file.
-----------------------------------------
package com.ControllerMapping;
import java.util.HashMap;
import java.util.Map;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

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

public class HelloController extends ParameterizableViewController{

@Override
public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response) throws Exception {
//ControllerClassNameHandlerMapping
String name=request.getParameter("name");
Map m=new HashMap();
m.put("msg", "Hello ... from ControllerClassURL mapping "+ name);
ModelAndView mvc=new ModelAndView(getViewName(),m);
System.out.println(" from controller mapping class");
return mvc;
}

}

-------------------------------------------------
Create Hello-servlet.xml file inside /WEB-INF folder

---------------------------------------------------

<!-- view resolver -->
