当session过期后可以用过滤器来设置重定向页面
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);
}
}
但是这样不能不能跳出iframe等框架。
可以用javaScript解决
在你想控制跳转的页面,比如login.jsp中的<head>与</head>之间加入以下代码:
<script language=”JavaScript”>
if (window != top)
top.location.href = location.href;
</script>
JS刷新框架的脚本语句
//如何刷新包含该框架的页面用
<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 rel="nofollow noopener noreferrer" href="javascript:opener.location.reload()">刷新</a> )
//如何刷新另一个框架的页面用
<script language=JavaScript>
parent.另一FrameID.location.reload();
</script>
如果想关闭窗口时刷新或者想开窗时刷新的话,在<body>中调用以下语句即可。
<body onload="opener.location.reload()"> 开窗时刷新
<body onUnload="opener.location.reload()"> 关闭时刷新
<script language="javascript">
window.opener.document.location.reload()
</script>
