БЛОГ НА HUSL


@RestController @Autowired Null

Автор вопроса: Egor

При попытке запроса метода, выдаёт NullPointerException конкретно по этому контроллеру. Есть похожие, и они абсолютно идентичные, в плане аннотаций и тд контроллеры. Пробовал разные аннотации на все из перечисленных классов. И конечно же на всех зависимостях есть нужные аннотации.

Exception

java.lang.NullPointerException: Cannot invoke "org.honeym.api.repository.PositionRepository.save(Object)" because "this.positionRepository" is null

Проблема решилась сама собой, после того как я пересоздал класс PositionController, скопировав оболочку класса из предыдущего заведомо рабочего контроллера, и поместив туда так же скопированную логику из не рабочего PositionController.
