I'm trying to create a Spring Boot REST application that has to make a remote REST call to another application protected by OAuth2.

The first application is using the Reactive WebClient to make the call to the second OAuth2 REST application. I've configured the `WebClient` with grant\_type "client\_credentials".

application.yml

```yaml
spring:
  security:
    oauth2:
      client:
        provider:
          client-registration-id:
            token-uri: http://localhost:8080/oauth/token
        registration:
          client-registration-id:
            authorization-grant-type: client_credentials
            client-id: public
            client-secret: test
            client-authentication-method: post
            scope: myscope

```

```java
@Configuration
public class WebClientConfig {

    @Bean
    WebClient webClient(ReactiveClientRegistrationRepository clientRegistrations) {
        ServerOAuth2AuthorizedClientExchangeFilterFunction oauth = new ServerOAuth2AuthorizedClientExchangeFilterFunction(
                clientRegistrations, new UnAuthenticatedServerOAuth2AuthorizedClientRepository());
        oauth.setDefaultClientRegistrationId("client-registration-id");
        return WebClient.builder().filter(oauth).build();
    }

}

```

```java
@Component
public class WebClientChronJob {

    Logger logger = LoggerFactory.getLogger(WebClientChronJob.class);

    @Autowired
    private WebClient webClient;

    @Scheduled(fixedRate = 5000)
    public void logResourceServiceResponse() {

        webClient.get()
                .uri("http://localhost:8080/test")
                .retrieve()
                .bodyToMono(String.class)
                .map(string -> "RESPONSE: " + string)
                .subscribe(logger::info);
    }

}

```

According to the article at [Baeldung Spring Webclient Oauth2](https://www.baeldung.com/spring-webclient-oauth2), the second time that `WebClientChronJob` runs, the application should request the resource without asking for a token first since the last one hasn't expired. Unfortunately, enabling the debug logs, I noticed the opposite: each time the job requests the resource it's asking for a new token. Please let me know if something is missing in configuration or code.
