в проекте я импортирую данные из базы данных Oracle в базу данных MySQL.Импорт работает нормально.Я пользователь hibernate envers для отслеживания изменений в определенном поле объекта.Однако, если я пытаюсь запросить сохраненные данные через конечную точку отдыха (контроллер -> служба -> хранилище), я получаю исключение.
Если я вызываю конечную точку ежедневно, приложение работает нормально.Но если конечная точка не запускается, например, в выходные дни, приложение завершает свою работу.
Следуя зависимостям, которые я использую в проекте:
