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。
