java - 按 F5 键后 Vaadin 8.3 session 失败

Question

我在 vaadin session 中使用 Jwt，当按 F5 时出现问题 Error Page

 private void onLogin(LoginForm.LoginEvent loginEvent) {
    String enteredUsername = loginEvent.getLoginParameter("username");
    String enteredPassword = loginEvent.getLoginParameter("password");

    AuthenticationResponse response = apiExecutorService.doAdminAuthentication(enteredUsername, enteredPassword);

    if (response != null && StringUtils.isNotBlank(response.getAccessToken())) {
        // Put token into session params
        String test = response.getAccessToken();
        VaadinSession.getCurrent().setAttribute("access_token", response.getAccessToken());
        VaadinSession.getCurrent().setAttribute("refresh_token", response.getRefreshToken());

        Notification...

        // Wait and redirect to admin page
        Page current = Page.getCurrent();
        notification.addDetachListener(event -> current.setLocation("/admin"));

你可以使用这个拐杖:

addShortcutListener(new ShortcutListener("刷新", ShortcutAction.KeyCode.F5, null) {
@覆盖
公共(public)无效handleAction(对象发送者，对象目标){
刷新网格()；
}
});
