Change to lambda

                http.oauth2Client(oauth2 -> oauth2
                        .authorizationCodeGrant(codeGrant -> codeGrant
                                .authorizationRequestRepository(this.authorizationRequestRepository())
                        )
                )
               .oauth2Login(oauth2 -> oauth2
                        .authorizationEndpoint(endpoint-> endpoint
                                .authorizationRequestRepository(this.authorizationRequestRepository())
                        )
                ).build();
