Я столкнулся с проблемой с полем даты / столбцом базы данных при использовании JpaRepository Spring для сохранения объекта в MySQL.
У объекта есть поля LocalDate.При тестировании с LocalDate.now () обнаружена проблема с возвращенным полем Date:
- Сначала сохраните правильную дату возвращаемого объекта.
- При возврате объекта из базы данных MySQL дата указывается за день до
Пример:
Ожидается: 2019-01-29
Факт: 2019-01-28
Я пробовал вчера, и результаты были:
Ожидаемое: 2019-01-28
Фактическое: 2019-01-27
Может быть похоже на эту JPA. Неправильная дата сохранения в базе данных MySQL

Я ожидаю, что поле даты не изменится после сохранения и возврата, но дата продолжает меняться на вчерашний ПОСЛЕ сохранения купона.
