解决session过期跳转到登陆页面并跳出iframe框架

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：

则在系统超时想在框架中打开登录页时，则login.jsp自身进行判断后跳出iframe等框架。

这段时间一直在休息，很久没写了，写点简单的吧。要开始学习啦！！！
