jsp页面

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<base href="<%=basePath%>">

<title>My JSP 'index.jsp' starting page</title>
<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="cache-control" content="no-cache">
<meta http-equiv="expires" content="0">
<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
<meta http-equiv="description" content="This is my page">

</head>

<body style="font-size:50px;">

<br/>
当前的时间是；
${date }<br/>
使用jstl标签：
<c:out value="${date}"></c:out>
</body>
</html>

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">



<servlet>

<servlet-name>springapp</servlet-name>

<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>

<url-pattern>*.do</url-pattern>
</servlet-mapping>

<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>

controller中的配置 HelloAction .java

package com.dragon.controller;

import java.util.Date;

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

import org.springframework.web.servlet.ModelAndView;

public class HelloAction implements
org.springframework.web.servlet.mvc.Controller {
//创建一个控制器类相当于 struts2 中的 action

//定义变量用来动态的保存需要跳转的页面
private String successView;

public String getSuccessView() {
return successView;
}

public void setSuccessView(String successView) {
this.successView = successView;
}

public ModelAndView handleRequest(HttpServletRequest request,
HttpServletResponse response) throws Exception {
//////////练习1/////////////////////////////
//获得当前的时间信息显示在页面中
Date date = new Date();

//返回视图名称模型名称模型的值
return new ModelAndView(this.getSuccessView(), "date", date);

// TODO Auto-generated method stub
//return new ModelAndView("index.jsp");
}

}
