If all you need to retrieve is the username,
getRequest().getRemoteUser() should be sufficient.

I need to get the current user and after searching forums and discussions and
examples about how to do this, I found that variations on the following code
seem to be considered a good way to get the current user:
SecurityContext ctx = null;
Authentication auth = null;
if( ctx == null )
{
ctx = SecurityContextHolder.getContext();
if ( auth == null && ctx.getAuthentication() != null )
auth = ctx.getAuthentication();
}
if ( auth != null )
{
String currentUser;
if ( auth.getPrincipal() instanceof UserDetails )
{
currentUser = ((UserDetails) auth.getPrincipal()).getUsername();
}
else
{
currentUser = String.valueOf( auth.getPrincipal() );
}
return currentUser;
}
But then, I did some more investigation and stumbled upon:
getRequest().getUserPrincipal().getName();
getRequest() returns an HttpServletRequest that is retrieved through a
FacesContext
getFacesContext().getExternalContext().getRequest();
So, which is the better way to get the current user? Personally, I like
using the request because it's a lot less code
and the BasePage class generated by AppFuse already has the
getRequest() method implemented, but the majority
of examples and forums used the first option through the
SecurityContext and Authentication object.
Thanks,
Tony
