Свойства конфигурации весенней загрузки не могут быть автоматически подключены в Koltin [kotlin.UninitializedPropertyAccessException]

Question

Я хотел бы получить значения параметров по умолчанию, когда пользователь регистрируется из файла свойств.

Для этого я создал класс для управления пользовательскими свойствами

DefaultProperties.kt

@PropertySource("classpath:config/defaults.yml")
@ConfigurationProperties("app.defaults")
class DefaultProperties {

    lateinit var settings: Settings

    class Settings {
        lateinit var keys: Keys
        var language: String = "en-US"
        var timezone: String = "GMT"
        var profilePicture: String = "default"
        var twoFactorAuth: Boolean = false

        class Keys{
            var language: String = "language"
            var timezone: String = "timezone"
            var profilePicture: String = "profile-picture"
            var twoFactorAuth: String = "two-factor-auto"
        }
    }
}

Затем я настраиваю свойства в defaults.yml, например:

app.defaults:
  settings:
    language: "fr-FR"
    two_factor: true

После этого я пытаюсь автоматически связать свойства

SettingsUtil.kt

@Component
class SettingsUtil{

    @Autowired
    lateinit var defaultProperties: DefaultProperties

    fun generateDefaultSettingsMap():MutableMap<String, String>{
        val defaultSettings = defaultProperties.settings
        val defaultKeys = defaultSettings.keys

        val defaultMap = mutableMapOf<String, String>()
        defaultMap[defaultKeys.language] = defaultSettings.language
        defaultMap[defaultKeys.timezone] = defaultSettings.timezone
        defaultMap[defaultKeys.profilePicture] = defaultSettings.profilePicture
        defaultMap[defaultKeys.twoFactorAuth] = defaultSettings.twoFactorAuth.toString()

        return defaultMap
    }

Чтобы наконец позвонить generateDefaultSettingsMap() от лица

User.kt

@Entity
@Immutable
@Cache(region = "userCache", usage = CacheConcurrencyStrategy.READ_ONLY)
data class User(

// Other code

    @ElementCollection
    @CollectionTable(name = "settings", joinColumns= [JoinColumn(name = "user_id", referencedColumnName = "user_id")])
    @MapKeyColumn(name = "key")
    @Column(name="value")
    var settings: MutableMap<String, String> = SettingsUtil().generateDefaultOptionsMap()

Результат, который я получаю при попытке зарегистрировать пользователя -

kotlin.UninitializedPropertyAccessException: lateinit property defaultProperties has not been initialized

Это полная трассировка стека

Есть идеи, что не так?

NB

1. В среде IDE отображается сообщение "Перезапустите процессор аннотаций конфигурации весенней загрузки для обновления сгенерированных метаданных".

2. я добавил @component в SettingsUtil так как @Autowired не может быть признан без него.
