How to pass the name to the page, not the login?

Question

Java

<li><a href="/profile">${pageContext.request.userPrincipal.name}</a></li>

With this code i get the login, but how do i get the username?

Answer 1

If we are talking about Spring Security, then
for this you need to override the UserDetailsService class, which will return, again, an overridden UserDetails with additional attributes. Then these attributes will be available.
An example of authorization through Active Directory - a bunch of different attributes are pulled out there.
