struts2 Web アプリケーションを開発しました。セッションモニターを行う必要があります。ユーザーがシステムにログインしない場合、またはセッション タイムアウトが発生した場合、自動的にログイン ページにリダイレクトする必要があります。

これは私のApplicationSessionMonitorです
public class ApplicationSessionMonitor extends ApplicationMonitor {
public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain chain) throws IOException, ServletException {
try {
HttpServletRequest request = (HttpServletRequest) servletRequest;
HttpSession session = request.getSession();
Object user = session.getAttribute("loged-user");
if (user == null) {
buildTempPath(session, requestedPath(request));
((HttpServletResponse) servletResponse).sendRedirect(contextPath);
} else {
goAhead(servletRequest, servletResponse, chain);
}
} catch (Exception e) {
e.printStackTrace();;
}
}
}
これは私のstruts.xmlです
<package name="default" extends="struts-default" namespace="/">
<action name="login" class="com.xont.tracker.login.action.LoginAction">
<result name="success" type="redirect">index.jsp</result>
<result name="temp_url" type="redirect">${temp_url}</result>
<result name="error">login.jsp</result>
<result name="input">login.jsp</result>
</action> .....
いつもそれは言うThe page isn't redirecting properly
。正しくリダイレクトできませんでした。何が問題なのか教えてください。
