Получение всех родительских данных в дочерней модели в ответ

0 голосов
/ 10 июня 2019

У меня есть две таблицы email_draft и email_draft_history.email_draft является родительской таблицей, и email_draft может иметь несколько email_draft_id.при попытке извлечь данные я получил все родительские данные и дочерние данные, но в дочерних данных я также получил родительские данные.

Сначала я попробовал fetch.lazy, но он дал мне ошибку, поэтому я должен пометить его как @JsonIgnore.Также я должен удалить ссылку на объект дочернего класса из tostring ().

Сначала я хочу получить родительские данные, а затем при необходимостиможет получить дочерние данные.И в дочерних данных я хочу получить только записи дочерних таблиц.

Я новичок в JPA, так что, думаю, я что-то здесь упустил.
