Question

我们将应用程序从Spring＆amp; amp; Hibernate 3.x到4.x.问题是现在已弃用AuthenticationException.getAuthentication（）。任何人都可以建议任何替代方案。以下是我们使用的代码：

public ModelAndView init(HttpServletRequest request, HttpServletResponse response){
    AuthenticationException exception = (AuthenticationException)request.getSession().getAttribute(WebAttributes.AUTHENTICATION_EXCEPTION);

    Authentication loginAuthentication = exception.getAuthentication();

    //Set the user name for the change password screen
    return new ModelAndView("common/changePassword", "userName", loginAuthentication.getPrincipal());   
}

有人能指出我替换它。网上没有多少。

如果在AuthenticationException的情况下执行以下代码，则表示您从登录表单提交的用户名和密码仍可在HttpServletRequest中使用。所以我认为你可以从那里获得用户名。

public ModelAndView init(HttpServletRequest request, HttpServletResponse response){
    AuthenticationException exception = (AuthenticationException)request.getSession().getAttribute(WebAttributes.AUTHENTICATION_EXCEPTION);

    String username = request.getParameter("<Name of your username parameter>");

    //Set the user name for the change password screen
    return new ModelAndView("common/changePassword", "userName", username);   
}

AuthenticationException.getAuthentication（）的替换;
