How to manually set an authenticated user in Spring Security / SpringMVC
- by David Parks
After a new user submits a 'New account' form, I want to manually log that user in so they don't have to login on the subsequent page.
The normal form login page going through the spring security interceptor works just fine.
In the new-account-form controller I am creating a UsernamePasswordAuthenticationToken and setting it in the SecurityContext manually:
SecurityContextHolder.getContext().setAuthentication(authentication);
On that same page I later check that the user is logged in with:
SecurityContextHolder.getContext().getAuthentication().getAuthorities();
This returns the authorities I set earlier in the authentication. All is well.
But when this same code is called on the very next page I load, the authentication token is just UserAnonymous.
I'm not clear why it did not keep the authentication I set on the previous request. Any thoughts?
Could it have to do with session ID's not being set up correctly?
Is there something that is possibly overwriting my authentication somehow?
Perhaps I just need another step to save the authentication?
Or is there something I need to do to declare the authentication across the whole session rather than a single request somehow?
Just looking for some thoughts that might help me see what's happening here.
