No Bean Found in Spring Boot application context

@Data
@AllArgsConstructor
@NoArgsConstructor
@Component
@Configuration
@ConfigurationProperties("promotion")
public class PromotionConfig {
    private AppClientConfig appConfig;
}


@Data
@Builder
@NoArgsConstructor
@AllArgsConstructor
public class AppClientConfig {
   private int readTImeout;
   private int writeTimeout;
}

When I am trying to do @Autowire PromotionConfig It is throwing an error that No Qualifying bean found for AppClientConfig.

I know this error is coming up because I dont have @Component in AppClientConfig.

How can i make it work without adding @Component in AppClientConfig. I want to keep it Plain POJO class.

My local.yml file

promotion:
  appConfig:
    readTImeout: 10
    writeTimeout: 10
