(十三):session属性范围 (JSP学习第三天)
session 属性范围
在一次会话范围内,无论何种跳转都可以使用,但新开浏览器就无法使用
设置session属性范围 session_scope_01.jsp
<%@ page language="java" contentType="text/html" pageEncoding="UTF-8"%>
<%@ page import="java.util.*"%>
<html>
<head>
<title>测试</title>
</head>
<body>
<%
session.setAttribute("name","小明");
session.setAttribute("birthday",new Date());
%>
<a href="session_scope_02.jsp">session跳转</a>
</body>
</html>
跳转后的页面 session_scope_02.jsp
<%@ page language="java" contentType="text/html" pageEncoding="UTF-8"%>
<%@ page import="java.util.*"%>
<html>
<head>
<title>测试</title>
</head>
<body>
<%
String username=(String)session.getAttribute("name");
Date birthday=(Date)session.getAttribute("birthday");
%>
<h1><%=username%></h1>
<h2><%=birthday%></h2>
</body>
</html>
