當session到期後可以用過濾器來設定重新導向頁面
複製代碼 代碼如下:
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);
}
}
但是這樣不能不能跳出iframe等架構。
可以用javaScript解決
在你想控制跳轉的頁面，比如login.jsp中的<head>與</head>之間加入以下代碼：
複製代碼 代碼如下:
<script language=”JavaScript”>
if (window != top)
top.location.href = location.href;
</script>
JS重新整理架構的指令碼語句
複製代碼 代碼如下:
//如何重新整理包含該架構的頁面用
<script language=JavaScript>
parent.location.reload();
</script>
//子視窗重新整理父視窗
<script language=JavaScript>
self.opener.location.reload();
</script>
( 或 <a href="javascript:opener.location.reload()">重新整理</a> )
//如何重新整理另一個架構的頁面用
<script language=JavaScript>
parent.另一FrameID.location.reload();
</script>
如果想關閉視窗時重新整理或者想開窗時重新整理的話，在<body>中調用以下語句即可。
<body onload="opener.location.reload()"> 開窗時重新整理
<body onUnload="opener.location.reload()"> 關閉時重新整理
<script language="javascript">
window.opener.document.location.reload()
</script>
