ModelAndView返回模型数据和视图。参考以下Demo代码，了解其实现方法。关注通过视图名称创建ModelAndView的构造方法，以及通过${requestScope.attribute}的方法获取model数据的方式。
控制器代码：
package com.tiekui.springmvc.handlers;
import java.util.Date;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
@Controller
public class ModelAndViewTest {
@RequestMapping("testModelAndView")
public ModelAndView testModelAndView() {
String viewname = "success";
ModelAndView modelAndView = new ModelAndView(viewname);
modelAndView.addObject("time", new Date());
return modelAndView;
}
}
视图代码 success.jsp：
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
<h1>Hello SpringMVC View</h1>
time : ${requestScope.time}

视图代码 index.jsp
