本文实例讲述了JSP中隐式对象用法。分享给大家供大家参考，具体如下：

<%@ 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 'demo1.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> <%   Date date=new Date();  out.write(date.toLocaleString()+"<br/>"); %> <%  //域之间的信息获取  request.setAttribute("data", "abc");//request的域  String data=(String)pageContext.getAttribute("data", PageContext.REQUEST_SCOPE);//用pageContext域获取Request域的内容  out.write(data+"<br/>");  String data2=(String)pageContext.findAttribute("data");//直接寻找data  out.write(data2+"<br/>"); %> ${data}<!-- 正则表达式 --> <!--   <jsp:forward page="/1.jsp"></jsp:froward>//配置首页时跳转到servlet  <jsp:include page="/1.jsp"></jsp:include><%--pageCpntext.include()动态包含--%>  //携带参数  <jsp:forward page="/1.jsp">   <jsp:param name="data" value="data"></jsp:param>  </jsp:froward> --> </body></html>

希望本文所述对大家JSP程序设计有所帮助。
