@Bean
public OAuth2AuthorizedClientManager authorizedClientManager(
        ClientRegistrationRepository clientRegistrationRepository,
        OAuth2AuthorizedClientRepository authorizedClientRepository) {

    OAuth2AuthorizedClientProvider authorizedClientProvider =
            OAuth2AuthorizedClientProviderBuilder.builder()
                    .clientCredentials()
                    .build();

    DefaultOAuth2AuthorizedClientManager authorizedClientManager =
            new DefaultOAuth2AuthorizedClientManager(
                    clientRegistrationRepository, authorizedClientRepository);
    authorizedClientManager.setAuthorizedClientProvider(authorizedClientProvider);

    return authorizedClientManager;
}

@Autowired
private WebClient.Builder webClientBuilder;

public Mono<String> fetchData() {
    return webClientBuilder.build()
            .get()
            .uri("https://api.example.com/data")
            .attributes(clientRegistrationId("your-client-registration-id"))
            .retrieve()
            .bodyToMono(String.class);
}
