      public Authentication authenticate(Authentication authentication) throws AuthenticationException
      Description copied from interface: AuthenticationProvider

      Specified by:
      authenticate in interface AuthenticationProvider
      Parameters:
      authentication - the authentication request object.
      Returns:
      a fully authenticated object including credentials. May return null if the AuthenticationProvider is unable to support authentication of the passed Authentication object. In such a case, the next AuthenticationProvider that supports the presented Authentication class will be tried.

    • supports

      public boolean supports(Class<?> authentication)
      Description copied from interface: AuthenticationProvider
      Returns true if this AuthenticationProvider supports the indicated Authentication object.

      Returning true does not guarantee an AuthenticationProvider will be able to authenticate the presented Authentication object. It simply indicates it can support closer evaluation of it. An AuthenticationProvider can still return null from the AuthenticationProvider.authenticate(Authentication) method to indicate another AuthenticationProvider should be tried.

      Selection of an AuthenticationProvider capable of performing authentication is conducted at runtime by the ProviderManager.

      Specified by:
      supports in interface AuthenticationProvider
      Returns:
      true if the implementation can more closely evaluate the Authentication class presented
