本文实例讲述了jsp中变量及方法的声明与使用。分享给大家供大家参考，具体如下：
<%@ page language="java" import="java.util.*" contentType="text/html;charset=GBK"%>
<%
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>JSP 中声明的使用</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>
<h1 align="center">演示声明的使用</h1>
<%--声明变量--%>
<%!long i = 1,j=1; %>
<%!String name="陈宁"; %>
<%!String name2="官林辉"; %>
<%--声明方法--%>
<%!public String sayHello(String who)
{
return "您好："+who;
}
%>
<p align="center">
<%
out.println(sayHello(name));
out.println("<br>");
out.println("您是第"+i+"个访问本网站的用户！");
i++;
%>
<% Date time = new Date();
out.write(time.toLocaleString());
%>
</p>
<p align="center">
<%=sayHello(name2)%>
<br>
您是第<%= j%>个访问本网站的用户！
<%j++;%>
</p>
</body>
</html>
希望本文所述对大家jsp程序设计有所帮助。
