我试图代码使用Tomcat 7过滤器映射着调度员在执行JSF导航,则不会调用
我有两个页面的登录系统一个简单的JSF Web应用程序:和的index.xhtml /restricted/welcome.xhtml。
下面的页面“/限制/ *”应是唯一的访问用户登录。
直接冲浪的welcome.xhtml导致执行我的过滤器,从的index.xhtml转发到welcome.xhtml绕过过滤。我无法想象为什么过滤器没有执行。
RestrictedAreaFilter.java:
@WebFilter(value = { "/restricted/*" }, dispatcherTypes = { DispatcherType.FORWARD, DispatcherType.REQUEST, DispatcherType.ASYNC, DispatcherType.ERROR, DispatcherType.INCLUDE })
public class RestrictedAreaFilter implements Filter {
@Override
public void destroy() {
}
@Override
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
HttpServletRequest httpReq = (HttpServletRequest) request;
User user = (User) httpReq.getSession().getAttribute("user");
if (user != null && user.isLoggedIn()) {
chain.doFilter(request, response);
} else {
httpReq.getRequestDispatcher("/access_denied.xhtml").forward(request, response);
}
}
@Override
public void init(FilterConfig arg0) throws ServletException {
}
}

bean的作用域User?尝试删除cookies并重试访问 –
嗨Jigar Joshi。 用户bean是会话作用域。用删除的Cookie和新的浏览器对其进行测试。 – BlackEye
您正在向'welcome.xhtml'直接发出GET请求,对吧? –
