解决static类使用@Value获取yml文件获取不到的问题

public class ServiceClass {

    @Value("${fileFormatConfig.picture}")
    private String PICTURE_FORMAT;
    @Value("${fileFormatConfig.video}")
    private String VIDEO_FORMAT;
    @Value("${fileFormatConfig.audio}")
    private String AUDIO_FORMAT;

    public void startDetection() {
        //调用静态工具类
        TestUtils.init(PICTURE_FORMAT, VIDEO_FORMAT, AUDIO_FORMAT);
        TestUtils.originalTextDetection();
    }

}

public class TestUtils {
    private static String PICTURE_FORMAT;
    private static String VIDEO_FORMAT;
    private static String AUDIO_FORMAT;

    // 静态setter，由外部类的某个方法（如@PostConstruct）调用
    public static void init(String pictureFormat, String videoFormat, String audioFormat) {
        PICTURE_FORMAT = pictureFormat;
        VIDEO_FORMAT = videoFormat;
        AUDIO_FORMAT = audioFormat;
    }

    public static void originalTextDetection() {
        System.out.println(PICTURE_FORMAT);
        System.out.println(VIDEO_FORMAT);
        System.out.println(AUDIO_FORMAT);
    }

}
