Spring Security : Check if user is from remember me cookie

This Spring Security example shows you how to check if a user is login from a “remember me” cookie.


  private boolean isRememberMeAuthenticated() {

	Authentication authentication = 
		SecurityContextHolder.getContext().getAuthentication();
	if (authentication == null) {
		return false;
	}

    return RememberMeAuthenticationToken.class.isAssignableFrom(authentication.getClass());
  }
	
  @RequestMapping(value = "/admin/update**", method = RequestMethod.GET)
  public ModelAndView updatePage() {

	ModelAndView model = new ModelAndView();

	if (isRememberMeAuthenticated()) {	
		model.setViewName("/login");	
	} else {
		model.setViewName("update");
	}

	return model;

  }

In Spring Security tag, you can code like this :


<%@taglib prefix="sec" uri="http://www.springframework.org/security/tags"%>
<%@page session="true"%>
<html>
<body>

	<sec:authorize access="isRememberMe()">
		<h2># This user is login by "Remember Me Cookies".</h2>
	</sec:authorize>

	<sec:authorize access="isFullyAuthenticated()">
		<h2># This user is login by username / password.</h2>
	</sec:authorize>

</body>
</html>

Note
isRememberMe() – Returns true if the current principal is a remember-me user
isFullyAuthenticated() – Returns true if the user is not an anonymous or a remember-me user

isRememberMeAuthenticated() always return false even I checked remember-me. I debugged and see authentication.getClass() always return class org.springframework.security.authentication.UsernamePasswordAuthenticationToken not RememberMeAuthenticationToken. Could you pls help, mkyong?
