I have a small question regarding the
I noticed that when I use the following lines the
is not really (or never ???) updated :
Authentication auth = new UsernamePasswordAuthenticationToken(authUser, null, authorities); SecurityContext sc = new SecurityContextImpl(); sc.setAuthentication(auth); SecurityContextHolder.setContext(sc);
However, if i use the following lines, the
is systematically updated :
Authentication auth = new UsernamePasswordAuthenticationToken(authUser, null, authorities); SecurityContextHolder.getContext().setAuthentication(auth);
So, the line
does correctly update the security context.
But aren't these two ways of doing the same thing ?
Why does the first method does not work ?
Thanks for enlightening me.

The SecurityContextHolder is able to reterieve the context from threadlocal, which is where it is kept/stored by Spring.
It is sorta covered in the
JavaRanch Style Guide
subject: Updating SecurityContext
nullpointer with @Autowired AuthenticationManager
Authenticating in Spring Security with password and username in url
Spring Security 2.0.4 .... Redirect user to original page after authentication success or failure
Spring 3 and X.509 Authentication
is this class thread-safe ?
