authenticationmanagerbuilder

httpsecurity.authenticationprovider(...)

@configuration @enablewebsecurity public class securityconfig extends websecurityconfigureradapter{    @autowired   private myauthenticationprovider myauthenticationprovider;    @autowired   @override   protected void configure(authenticationmanagerbuilder auth) throws exception {       auth.authenticationprovider(myauthenticationprovider);   }    // --------------- or/and ? ----------------   @override   protected void configure(httpsecurity http) throws exception {       http       .authenticationprovider(myauthenticationprovider)       // ...   } }

you need use 1 of 2 options. internally, http.authenticationprovider making call authenticationmanagerbuilder.authenticationprovider.
