Данные Spring JPA (Hibernate) против базы данных Postgres - схема по умолчанию (Ошибка создания боба с именем 'EntityMan ⇐ JAVA

[Anonymous]

Я проводил учебный проект, где для каждой новой темы по данным Spring JPA/Hibernate I создавал новое приложение/схему в Postgres. JPA EntityManagerFactory: [PersistenceUnit: Default] Невозможно создать Hibernate SessionFactory; Вложенное исключение-org.hibernate.mappingException: не может создать создание генератора ID [entity-name = org.as.spring.boot.tutorial.postgres.domain.authoretity] < /p>
< /blockquote>
В какой-то момент я понял, что hibernate не использовал Schema i spected in anptaint. class = "lang-ini prettyprint-override">spring.datasource.driverClassName=org.postgresql.Driver
spring.datasource.url=jdbc:postgresql://X.X.X.X:5432/spring_boot
spring.datasource.username=XXXXX
spring.datasource.password=XXXXX
spring.jpa.show-sql = true
spring.jpa.hibernate.ddl-auto=update
spring.jpa.properties.hibernate.default_schema=spring_boot_rest
< /code>
Я попытался изменить его на стороне Postgres с: < /p>

Изменение базы данных spring_boot set search_path to spring_boot_rest; < /p>

Это было на самом деле, но это не было, что я не был. Application. стек-трасса: < /p>
Примечание. Основные проблемы с трассе стека, возникающие из-за попытки подключиться к неправильной схеме, где аналогичные объекты уже были созданы с различными свойствами.org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaConfiguration.class]: [PersistenceUnit: default] Unable to build Hibernate SessionFactory; nested exception is org.hibernate.MappingException: Could not instantiate id generator [entity-name=org.as.spring.boot.tutorial.postgres.domain.AuthorEntity]
