直接复制粘贴下面代码即可实现页面十秒后跳转到对应页面：


<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<% 
      String url = basePath;   //设置跳转的地址
%>
<html>
   <head>            
   <meta http-equiv=refresh content=10;url=<%=url %>>           
   </head> 
       <body>
       <div align="center">
<h2 style=color:red>请使用您的账号登陆系统</h2>
<h2 style=color:red><span id=jump>10</span> 秒钟后页面将自动返回登录页面...</h2>
<h2><a href="javascript:void(0);" onclick="jumpToIndex()">点击此处立即跳转至首页</a></h2>
</div>     
      </body>
        <script>
             function countDown(secs){
                       jump.innerText=secs;
                       if(--secs>0)
                                setTimeout("countDown("+secs+" )",1000);
             }
             countDown(10);      
function jumpToIndex(){
window.location.href='<%=url %>';
}
       </script>
</html>
