import java.util.Map;

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

public class TestController implements Controller{

	public ModelAndView handerRequest(HttpServletRequest request, HttpServletResponse response) throws Exception {
		// TODO Auto-generated method stub
		String name = request.getParameter("name");
		if(name==null){
			name="world";
		}
		Map<String,Object> model = new HashMap<String,Object>();
		model.put("message", "this is a testcontroller");
		model.put("greet", "Hello "+name+"!");
