Question

Я хочу использовать IgniteRepository и метод запроса. Метод «save» и метод «findAll» - это нормально, но когда я пытаюсь найти данные по id, у меня возникают проблемы с использованием метода «findById». Можно ли использовать метод запроса путем зажигания хранилища? (В кэше Ignite используется формат Key-Value. Мне также интересно узнать идентификатор в «findById» в IgniteRepository, означающий значение ключа или @id.)

Ниже приводится сообщение об ошибке.
