Using Spring, how can I manually fire AuthenticationSuccessHandler

Question

I want to provide the user an alternative means of logging in with a token. I already handle authenticating the user in the PreAuthenticationFilter class but then I need to fire my

AuthenticationSuccessHandler.onAuthenticationSuccess()

which does a

super.onAuthenticationSuccess()

which fires the method in it's base class of

SavedRequestAwareAuthenticationSuccessHandler.

How can I fire the AuthenticationSuccessHandler from my preauthentication filter? I tried setting the authentication of the SecurityContextHolder thinking it would automatically fire off the AuthenticationSuccessHandler but it does not. This is how I tried to do that:

Authentication authentication = new UsernamePasswordAuthenticationToken(Username, Password);
SecurityContextHolder.getContext().setAuthentication(authentication);

Unfortunately, that doesn't work though. So I need to know how to fire the AuthenticationSuccessHandler from a preauthentication filter.

Answer 1

You could probably be inspired of how the RememberMeAuthenthicationFilter works in spring-security. It has a reference to the AuthenticationSuccessHandler , and calls onAuthenticationSuccess manually.

Answer 2

You have to extend the PreAuthenticationFilter and overwrite the method successfulAuthentication. There you can trigger your injected success handler.
