项目中登录的路径：/user/login.action 现在要多登录过滤，如果没用户登录就跳到登录页面，我的filter方法如下：public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException,
ServletException {
HttpSession session = ((HttpServletRequest) request).getSession();
HttpServletRequest httpReq = (HttpServletRequest) request;
HttpServletResponse httpRes = (HttpServletResponse) response;
String url = httpReq.getServletPath();
String path = httpReq.getContextPath();
//把login.jsp排除掉
if ((url.startsWith("/")&& !url.startsWith("/user/login")&& !url.startsWith("/login.jsp"))) {// 若访问后台资源
User user = (User) session.getAttribute("user");
if (user == null) {// 转入管理员登陆页面
httpRes.sendRedirect(path + "/login.jsp");
return;
}
}
chain.doFilter(request, response);
}，现在直接输入登录的long.action是报错的，因为我把login.action没给过滤，如果不加")&& !url.startsWith("/user/login")这句的话，他就会过滤这个login.action，跑到登录页面，当我输入登录信息，点击登录时，它还会走这个过滤方法，求解决方法
