我的annotation@Value返回null,即使它被使用并调用到组件注释类中

我想使用应用程序属性而不是硬编码它,但它总是返回null。IntelliJ将它正确地计算为我在文件中设置的值。 其他一切都如我所愿。任何方向都很感激!

api.someapiservice.key=08e...f

使用属性值的类:

@Component
public class ApiClient implements ApiClientInterface {

@Value("${api.someapiservice.key}")
private String API_KEY;

public ApiClient () {
    System.out.println(API_KEY); //Returns null after spring log info: Initialized JPA EntityManagerFactory for persistence unit 'default'
    ...
}

@Component
public class SomeService {

private final SomeRepository someRepository;
private final ApiClient apiClient;

public PlaylistService(SomeRepository someRepository , ApiClient apiClient ) {
    this.SomeRepository = SomeRepository;
    this.apiClient = ApiClient;
}
