Я новичок в Котлин так, может быть, я неправильно что-то, кроме этого класса:Весна не может обработать метод, возвращающий общий внутренний Котлин класс
@Component
open class SimpleStoreBuilder {
open fun <T : Entity> build(tableName: String): Store<T>? {
return Store()
}
inner class Store<T:Entity>
}
бросает это исключение во время выполнения
