Jsp中解决session过期跳转到登陆页面并跳出iframe框架的方法
当session过期后可以用过滤器来设置重定向页面复制代码 代码如下: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中的与之间加入以下代码：复制代码 代码如下:JS刷新框架的脚本语句复制代码 代码如下://如何刷新包含该框架的页面用 //子窗口刷新父窗口( 或 刷新 )//如何刷新另一个框架的页面用 如果想关闭窗口时刷新或者想开窗时刷新的话，在中调用以下语句即可。 开窗时刷新 关闭时刷新
