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。
