SpringMVC Map Model ModelMap 和 ModelAndView

代码:

package com.gaussic.controller;

import com.gaussic.model.AccountModel;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.ui.ModelMap;
import org.springframework.web.servlet.ModelAndView;

import java.util.Arrays;
import java.util.Map;
import java.util.Date;

/**
 * Created by Administrator on 2016/9/9 0009.
 */
@Controller
@RequestMapping(value = "/test")
public class TestController {
    @RequestMapping("/test")
    public String test(Map<String,Object> map,Model model,ModelMap modelMap){
        map.put("names", Arrays.asList("caoyc","zhh","cjx"));
        model.addAttribute("time", new Date());
        modelMap.addAttribute("city", "ChengDu");
        modelMap.put("gender", "male");
        return "/test/hello";
    }

    @RequestMapping(value="/index", method = {RequestMethod.GET})
    public ModelAndView index(){
        ModelAndView modelAndView = new ModelAndView();
        modelAndView.addObject("message", "Hello World!");
        modelAndView.setViewName("/test/index");
        return modelAndView;
    }
}

前端:

hello.jsp

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>Title</title>
</head>
<body>
1 1、time:${requestScope.time}
2 <br/>2、names:${requestScope.names }
3 <br/>3、city:${requestScope.city }
4 <br/>4、gender:${requestScope.gender }
</body>
</html>

index.jsp

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>Title</title>
</head>
<body>
${message}
</body>
</html>

都可以向视图层传递参数

ModelAndView还可以指定跳转路径
