1.JSP入门演示:
此jsp页面会显示当前时间：
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8" errorPage="/errors/error.jsp"%>
<%
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>
<title>JSP入门(输出时间)</title>
</head>
<body>
当前时间值是：
<%
Date date=new Date();
String time = date.toLocaleString();
out.write(time);
%>
<br/>
<%= time %>
</body>
</html>
2.静态包含
静态包含是几个JSP页面包含在一个JSP页面中，翻译成的Servlet也是一个
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>include指令</title>
</head>
<body>
<%@include file="/public/head.jsp" %>
aaaaaaaaaaaaaaaaaaaaaaaaa<br/>
<%@include file="/public/foot.jsp" %>
</body>
</html>
3.动态包含
动态包含是几个JSP页面包含在一个JSP页面中，翻译成的Servlet也是多个，只不过是访问时服务器把多个Servlet整合在一起
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>动态包含</title>
</head>
<body>
<%
request.getRequestDispatcher("/public/head.jsp").include(request,response);
%>
bbbbbbbbbbbbbbbbbbbbbb<br/>
<%
request.getRequestDispatcher("/public/foot.jsp").include(request,response);
%>
</body>
</html>
