The AuthenticationManager interface

First of all, AuthenticationManager is a single-method interface:

public interface AuthenticationManager { Authentication authenticate(Authentication authentication) throws AuthenticationException; }

Spring Security provides one implementation: ProviderManager. This implementation allows us to plug in several AuthenticationProviders. The ProviderManager tries all the AuthenticationProviders in order, calling their authenticate method. The code is as follows:

public interface AuthenticationProvider { Authentication authenticate(Authentication authentication) throws AuthenticationException; boolean supports(Class<?> authentication); }
