package com.study.controller;

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

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

public class UserController implements Controller{

public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response) throws Exception {

ModelAndView mv = new ModelAndView();

mv.addObject("hello", "springmvc你好!又见面了.");

mv.setViewName("index");

return mv;
}

}
