Spring框架---springmvc中ModelAndView简单使用

我们先看图来演示一下ModelAndView这个方法 

 

再来看源码 

package com.qcr.controllers;


	import java.util.ArrayList;
	import java.util.HashMap;
	import java.util.Map;
	import org.springframework.stereotype.Controller;
	import org.springframework.web.bind.annotation.RequestBody;
	import org.springframework.web.bind.annotation.RequestMapping;
	import org.springframework.web.bind.annotation.RequestMethod;
	import org.springframework.web.bind.annotation.RequestParam;
	import org.springframework.web.bind.annotation.ResponseBody;
	import org.springframework.web.servlet.ModelAndView;
	@Controller
	public class Goods {
		@ResponseBody
		

	    @RequestMapping(value ="views/goods",method ={RequestMethod.GET})
	    public ModelAndView goods(String name){ 
			System.out.println(1231);
	    	ModelAndView mv = new ModelAndView();
	    	mv.addObject("title","EN MÉRINOS");
	    	mv.addObject("price","1,000$");
	    	mv.addObject("desc","Cardigan à manches longues en laine mérinos. Encolure ronde. Fermeture par boutons recouverts de maille. Finition bords côtes bas de manches et de vêtement. Visuel retouché.");
	    	mv.addObject("url","http://localhost:8080/shopping/views/images/goods/p1.jpg");
	    	mv.setViewName("goods/Goods_page");
	        return mv;
	    }
	}

我们在这个方法里首先用ModelAndView定义了一个mv对象,然后用add方法往里面添加数据,最后return回去.
