For field injection:

Fields are injected right after construction of a bean, before any config methods are invoked. Such a config field does not have to be public. Refer Autowired annotation for complete usage. Use constructor injection in this case like below:

@Component
public class TMDbWarper {

    private TMDbConfig tmdbConfig;

    private TmdbApi tmdbApi;

    @Autowired
    public TMDbWarper(final TMDbConfig tmdbConfig){
            this.tmdbConfig = tmdbConfig;
            tmdbApi = new TmdbApi(tmdbConfig.getApiKey());
    }

(or)

Use @PostConstruct to initialise like below:

@Component
public class TMDbWarper {

    @Autowired
    private TMDbConfig tmdbConfig;

    private TmdbApi tmdbApi;

    @PostConstruct
    public void init() {
        // any initialisation method
        tmdbConfig.getConfig();
    }
