Autowiring a non-primitive with spring annotations like bellow works:
@Autowired
lateinit var metaDataService: MetaDataService
But this doesn't work:
@Value("\${cacheTimeSeconds}")
lateinit var cacheTimeSeconds: Int
Error:
lateinit modifier is not allowed for primitive types.
How to autowire primitve properties into Kotlin classes?
You can also use the @Value annotation within the constructor:
This has the benefit that your variable is final and none-nullable. I also prefer constructor injection. It can make testing easier.
