我为我想保护的任何页面配置了认证过滤器。 然而,当它试图重定向到登录页面,我遇到下面的错误JSF重定向导致过滤器中的异常
com.sun.faces.context.FacesFileNotFoundException
..here是我的过滤器
@WebFilter(filterName = "Authentication Filter", urlPatterns = { "/pages/*" }, dispatcherTypes = {
DispatcherType.REQUEST, DispatcherType.FORWARD })
public class AuthenticationFilter implements Filter {
static final Logger logger = Logger.getLogger(AuthenticationFilter.class);
private String contextPath;
public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain) throws IOException, ServletException {
HttpServletRequest httpRequest = (HttpServletRequest) request;
HttpServletResponse httpResponse = (HttpServletResponse) response;
if (httpRequest.getUserPrincipal() == null) {
httpResponse.sendRedirect(contextPath
+ "/faces/pages/public/login.xhtml");
return;
}
chain.doFilter(request, response);
}
public void init(FilterConfig fConfig) throws ServletException {
contextPath = fConfig.getServletContext().getContextPath();
}
}
..和我的web.xml文件中映射与此代码为面临的servlet
<servlet>
<servlet-name>Faces Servlet</servlet-name>
<servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>*.xhtml</url-pattern>
</servlet-mapping>
不知道,但我已验证的路径在我的项目文件夹中现有的
+pages
+public
-login.xhtml
生成的路径是
http://localhost:8080/MyApp/faces/pages/public/login.xhtml
任何人都知道的原因是什么?
