登录前，服务器页面重定向到Filer [英] Server page redirected to Filer before Login
本文介绍了登录前，服务器页面重定向到Filer的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我刚刚部署了一个具有登录页面的应用程序。但是，使用正确密码和用户名登录时，index.xhtml会收到错误，并始终重定向到已配置的过滤器（会话超时）。重定向的原因是什么？我检查了会话是否无效，但不是这样。
I have just deployed an Application which has a login page. Upon logging in with the "right" password and "username" however, the index.xhtml gets an error and gets ALWAYS redirected to the filter( a sessions time out) that has been configured. What are the reasons for the redirection? I made a check to see if the session was invalid, but no that was not the case. Here is the web.xml(part) where the filter has been set.
错误：
Error:
javax.faces.application.ViewExpiredException: viewId:/index.xhtml - Ansicht /index.xhtml konnte nicht wiederhergestellt werden.

这是过滤器代码：
public class SessionTimeoutFilter implements Filter {
//private String timeoutPage = "timeout.xhtml";
private String timeoutPage = "index.xhtml";
@Override
public void init(FilterConfig filterConfig) throws ServletException {
}
@Override
public void doFilter(ServletRequest request, ServletResponse response, FilterChain filterChain)
throws IOException, ServletException {
if ((request instanceof HttpServletRequest) && (response instanceof HttpServletResponse)) {
HttpServletRequest httpServletRequest = (HttpServletRequest) request;
HttpServletResponse httpServletResponse = (HttpServletResponse) response;
// is session expire control required for this request?
if (isSessionControlRequiredForThisResource(httpServletRequest)) {
// is session invalid?
if (isSessionInvalid(httpServletRequest)) {
String timeoutUrl = httpServletRequest.getContextPath() + "/" + getTimeoutPage();
//System.out.println("Session is invalid! redirecting to timeoutpage : "+timeoutUrl);
httpServletResponse.sendRedirect(timeoutUrl);
return;
}
}
}
**Line 53: ERROR here-->** filterChain.doFilter(request, response);
}
private boolean isSessionControlRequiredForThisResource(HttpServletRequest httpServletRequest) {
String requestPath = httpServletRequest.getRequestURI();
boolean controlRequired = !StringUtils.contains(requestPath, getTimeoutPage());
return controlRequired;
}
private boolean isSessionInvalid(HttpServletRequest httpServletRequest) {
boolean sessionInValid = (httpServletRequest.getRequestedSessionId() != null)
&& !httpServletRequest.isRequestedSessionIdValid();
return sessionInValid;
}
@Override
public void destroy() {
}
public String getTimeoutPage() {
return timeoutPage;
}
public void setTimeoutPage(String timeoutPage) {
this.timeoutPage = timeoutPage;
}
}
请指教！
推荐答案
问题是这样：
the problem is this line:
<filter-mapping>
<filter-name>SessionTimeoutFilter</filter-name>
<url-pattern>*.xhtml</url-pattern>
</filter-mapping>
尝试更改不包含您的登录页面或index.xhtml的url模式。
Try to change the url pattern that does not include the your login page or the index.xhtml.
