    • 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 instance of the Authentication class. 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 the ProviderManager.

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