How to get username after login with FORM based authentication

问题

I am following the link http://middlewaremagic.com/weblogic/?p=2034 to perform form based authentication. I have created a security realm then successfully delegate the authentication check to weblogic 10.3. Everything is fine, but I could not get username, HttpServletRequest->getRemoteUser() returns null.

Do you have an idea how to get username after login? I am going to use username in every Managed bean to log user operations.

EDIT: I have found my mistake that I invalidated the session before logging user operation (logout operation), that is why HttpServletRequest->getRemoteUser() returns null. Thanks for contribution.

回答1:

You can obtain it from SecurityContext as well :

SecurityContextHolder.getContext().getAuthentication().getPrincipal().getUserName();

回答2:

Try to get user principal from request and then get name from it. Like this:

Principal p = request.getUserPrincipal();
String username = p.getName();

回答3:

j_username is available in the Principe, so just check there is any Principle in the request object.

String username;
Principal principal = request.getUserPrincipal();
            if (principal != null) {
                username= principal.getName(); // Find User by j_username.
            }
