Я пытаюсь написать тест на сохранение. У меня есть проект Maven, и я использую Arquillian со встроенным контейнером из стеклянной рыбы, Hibernate (как мой поставщик JPA) и HSQLDB в качестве моего магазина.Исключение грамматики спящего режима с использованием JPA с hsqldb
Когда я запускаю мой тест я получаю исключение грамматики (я могу опубликовать полный трассировки стека, если необходимо:
javax.persistence.PersistenceException: org.hibernate.exception.SQLGrammarException: Syntax error: Encountered "identity" at line 1, column 6.
Бревна, кажется, чтобы показать таблицу создана правильно:
Hibernate:
create table Game (
id bigint generated by default as identity (start with 1),
title varchar(50) not null,
primary key (id)
)
Dumping old records...
Hibernate:
delete
from
Game
Inserting records...
Hibernate:
insert
into
Game
(id, title)
values
(default, ?)
Hibernate:
drop table Game if exists
Hibernate:
drop table Member if exists

'create = true' не обязательно, поскольку по умолчанию свойство true. 'create = false' используется, когда вы хотите, чтобы база данных уже была создана при попытке нового подключения. – fredt
@fredt Спасибо за обновление. В то время я делал ряд изменений, и у havent была возможность повторно посетить это. Я переучиваю позже и при необходимости отправлю EDIT – Romski
