Question

我知道这个问题已经讨论了很多次，但是，我没有设法直截了当。如果你看一下，我真的很感激。

所以，我有以下问题：

如果用户想通过链接访问我的应用程序，例如

http://example:8080/Kundenportal/protected/post/post.jsf

他将被重定向到我的loginPage（我有一个Phaselistener，验证是否登录）。

现在，登录后，用户想要

http://example:8080/Kundenportal/protected/post/post.jsf,

相反，他将被重定向到

http://example:8080/Kundenportal/protected/post/start.jsf.

如何告诉我的应用程序在登录后应该将用户重定向到哪里？我知道它可以通过HttpRequestServlet工作，但是在检查是否在Phaselistener中登录后，用户将被重定向到我的登录页面，这意味着requestURL是loginPage，这是错误的。

这是我的代码。

这是我的PhaseListener：

@Override
public void afterPhase(PhaseEvent event) {
    FacesContext fc = event.getFacesContext();
    String currentPage = fc.getViewRoot().getViewId();

    HttpServletRequest origRequest = (HttpServletRequest) fc
            .getExternalContext().getRequest();
    //  Here is the requestURI post.xhtml 
    String reqURI = origRequest.getRequestURI();

    // boolean loginPage = page.startsWith("/login.xhtml");
    // boolean registerPage = page.startsWith("/registrierung.xhtml");

    boolean loginRequired = currentPage.startsWith("/protected/");
    if (loginRequired && !loggedIn(fc)) {
        NavigationHandler nh = fc.getApplication().getNavigationHandler();
        nh.handleNavigation(fc, null, "loginFAILED");
        fc.renderResponse();

    }

}

好的，现在这就是我设置faces-confing.xhtml的方式：

at.ooev.kp.controller.login.LoggedInCheck

<application>
    <locale-config>
        <default-locale>de</default-locale>
        <supported-locale>de</supported-locale>

    <resource-bundle>

这是我登录时的managedBean：

@PermitAll
public String login() {
    FacesContext fc = FacesContext .getCurrentInstance();
    HttpServletRequest origRequest = (HttpServletRequest) fc.getExternalContext().getRequest();
    // The requestURI is here login.xhtml(because there was the redirection in the Phaselistener)
    String str = origRequest.getRequestURI();

    if (doLogin(credentials.getUsername(), credentials.getPassword())) {
        String realname = (!Utils.isEmpty(webbaUser.getVorname())) ? webbaUser
                .getVorname() + " "
                : "";
        realname += webbaUser.getName();
        user.setUsername(credentials.getUsername());
        user.setRealname(realname);
        user.setKndnr(credentials.getUsername());
        if ("kunde".equalsIgnoreCase(credentials.getUsername()))
            user.setKndnr("600828");
        user.setMailadresse(webbaUser.getEmail());
        user.setHostUserid(webbaUser.getHostuserid());

        HttpSession session = ((HttpServletRequest) FacesContext
                .getCurrentInstance().getExternalContext().getRequest())
                .getSession(false);
        session.setAttribute("LOGGEDINUSER", user.getUsername());
        dbLog.add(DbLogController.Aktion.LOGIN, user.getUsername());
        // List<String> kundennummern = webbaUser.getDatfilt();
        // for (String s : kundennummern)
        // System.out.println("datfilt: " + s);
        return "loginOK";
    } else {
        FacesContext.getCurrentInstance().addMessage(null,
                new FacesMessage("Anmeldung fehlgeschlagen!"));
        dbLog.add(DbLogController.Aktion.LOGINFAILED,
                credentials.getUsername());
        user = null;
        return null;
    }
}

将您的URL保存在阶段监听器中的LOGIN_REDIRECT等会话属性中，并在登录后使用它。

一些像spring security这样的框架会为你做这件事。

登录后导航到请求的页面
