springmvc的ModelAndView的简单使用

 参考：http://blog.csdn.net/zzjjiandan/article/details/34089313

先上图：

 

MAVTest.java

package com.wyl;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

/**
 * ModelAndView测试，
 *

 */
@Controller
public class MAVTest {

    public MAVTest() {
        // TODO Auto-generated constructor stub
    }

    @RequestMapping(value = "login")
    public ModelAndView login() {
        System.out.println("MAVTest.java login()....");
        ModelAndView mav = new ModelAndView();
        mav.setViewName("welcome");
        mav.addObject("msg", "hello kitty");

        // List
        List<String> list = new ArrayList<String>();
        list.add("java");
        list.add("c++");
        list.add("oracle");
        mav.addObject("bookList", list);

        // Map
        Map<String, String> map = new HashMap<String, String>();
        map.put("zhangsan", "北京");
        map.put("lisi", "上海");
        map.put("wangwu", "深圳");
        mav.addObject("map", map);

        return mav;
    }

}
