當session過時後能夠用過濾器來設置重定向頁面javascript

代碼以下:java

 
public class ActionFilter extends HttpServlet implements Filter { 
 
private FilterConfig filterConfig; 
 
public void init(FilterConfig config) { 
 
this.filterConfig = config; 
 
} 
 
public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws ServletException, IOException { 
 
HttpServletRequest req = (HttpServletRequest) servletRequest; 
 
servletRequest.setCharacterEncoding(「UTF-8″); 
 
HttpServletResponse res = (HttpServletResponse) servletResponse; 
 
String url = req.getRequestURI(); 
 
SysUserVOImpl user = (SysUserVOImpl) req.getSession().getAttribute(「SysUser」); 
 
if (null == user) { 
 
if (!COMMON.isEmpty(url) && (url.endsWith(「newestlogin.jsp」) || url.endsWith(「UserLoginAction.jsp」) || url.endsWith(「login.jsp」) || url.endsWith(「loginAction.do」))) { 
 
filterChain.doFilter(servletRequest, servletResponse); 
 
} else { 
 
req.getRequestDispatcher(「/newestlogin.jsp」).forward(req, res); 
 
} 
 
} else { 
 
filterChain.doFilter(servletRequest, servletResponse); 
 
} 
 
}

可是這樣不能不能跳出iframe等框架。
能夠用javaScript解決
在你想控制跳轉的頁面，好比login.jsp中的<head>與</head>之間加入如下代碼：session

代碼以下:

 
 <script language=」JavaScript」>  
 
 　　if (window != top)  
 
 　　top.location.href = location.href;  
 
 </script>

JS刷新框架的腳本語句框架

複製代碼代碼以下:

//如何刷新包含該框架的頁面用
<script language=JavaScript>
   parent.location.reload();
</script>
//子窗口刷新父窗口
<script language=JavaScript>
    self.opener.location.reload();
</script>
(　或　<a href="javascript:opener.location.reload()">刷新</a>   )
//如何刷新另外一個框架的頁面用
<script language=JavaScript>
   parent.另外一FrameID.location.reload();
</script>
若是想關閉窗口時刷新或者想開窗時刷新的話，在<body>中調用如下語句便可。
<body onload="opener.location.reload()"> 開窗時刷新
<body onUnload="opener.location.reload()"> 關閉時刷新
<script language="javascript">
window.opener.document.location.reload()
</script>jsp
