一、include指令_{(如：<%@include file="..."%> )}

示例：

Date.jsp

 <%@page import="java.text.SimpleDateFormat"%>

 <%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>

 <%

     Date d=new Date();

     SimpleDateFormat sf=new SimpleDateFormat("yyyy年MM月dd日");

     String s=sf.format(d);

     out.print(s);

 %>

include.jsp

 <%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>

 <%

 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 'include.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">

     <!--

     <link rel="stylesheet" type="text/css" href="styles.css">

     -->

   </head>

   <body>

     <h1>include指令</h1>

     <hr>

     <%@include file="Date.jsp" %>

   </body>

 </html>

运行界面：访问include.jsp界面

二、include动作_{(如: <jsp:include page="..." flush="false">)}

示例：

 <%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>

 <%

 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 'include.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">

     <!--

     <link rel="stylesheet" type="text/css" href="styles.css">

     -->

   </head>

   <body>

     <h1>include动作</h1>

     <hr>

     <jsp:include page="Date.jsp" flush="false"></jsp:include>

   </body>

 </html>
