我尝试使用注解来注册功能的设置，但无法反映设置字段，我做错了什么
这是功能初始化，我要添加设置

public Feature() {
    try {
        Class<SettingAnno> anno = SettingAnno.class;
        for (Field field : this.getClass().getDeclaredFields()) {
            if (field.isAnnotationPresent(anno)) {
                Setting setting = (Setting) field.get(this);
                this.settings.add(setting);
            }
        }
    }
    catch (Exception e) {
        e.printStackTrace();
    }
}

但是当我使用Setting setting = (Setting) field.get(this);时，它实际上将被设置为'null'
特征子项：

public final class FeatureChild extends Feature {
    @SettingAnno("setting1")
    public final BooleanSetting setting1 = new BooleanSetting(true);
}

BoolenSetting是设置子级
这是注解

@Target(ElementType.FIELD)
@Retention(RetentionPolicy.RUNTIME)
public @interface SettingAnno {
    String value();
}
