Я создал микросервис, используя jhipster и Spring boot.Сейчас я пытаюсь включить мультитенантность в нем.Для этого я следовал подходу на основе схемы Hibernate.Делая это, чтобы сделать бины моего пользовательского MultiTenantConnectionProvider и текущего CurrentTenantIdentifierResolver доступными в контейнере Spring, я написал конфигурацию Hibernate, которая прилагается ниже.
Все работает нормально, если я пропущу тестовые случаи.Когда я компилирую свое приложение для запуска с тестовыми примерами, тестовые случаи терпят неудачу.Одно из отличий состоит в том, что, когда приложение работает в режиме разработки, оно должно использовать базу данных MySQL, тогда как для выполнения тестовых случаев оно должно использовать внутреннюю базу данных H2.
Теперь полученная ошибка

Цена столбца типа float, и я хотел бы оставить его равным.Я также выяснил, что в application.yml для теста свойство database-platform установлено в io.github.jhipster.domain.util.FixedH2Dialect, которое имеет registerColumnType (Types.FLOAT, "real");
Поэтому с типом данных float не должно возникнуть никаких проблем.Но я не понимаю, почему я получаю эту ошибку тогда.Любое руководство или предложение было бы действительно здорово.
