java.sql.SQLSyntaxErrorException: неизвестный столбец .JPA Entity Issue?

/ 12 мая 2019

У меня есть ошибка , когда я пытаюсь отправить GET-запрос в мое Spring Boot Application, и я не знаю, что я пропустил!

У меня есть база данных и я создал JPA Entities и связи в Eclipse с STS (Spring Tool Suite), установленным для моего Spring Boot Project, соответственно.

Созданные объекты являются:

В трассировке стека при попытке выполнить метод listaRistoranti (RistoranteRepositoryImpl.java:54) в классе Entity Ristorante, jpa преобразует имя столбца, заданное как @Column(name = "idRistorante"), в случай верблюда id_ristorante, тогда как в базе данных само имя столбца idRistorante, что вызывает проблему.

Из Настройка стратегии именования Hibernate раздела Руководства по доступу к данным Spring :

Hibernate использует два разных стратегии именования для сопоставления имен из модели объекта с соответствующими именами базы данных.Полное имя класса физической и неявной реализации стратегии можно настроить, задав spring.jpa.hibernate.naming.physical-strategy and spring.jpa.hibernate.naming.implicit-strategy properties соответственно.В качестве альтернативы, если в контексте приложения доступны компоненты ImplicitNamingStrategy или PhysicalNamingStrategy , Hibernate будет автоматически настроен для их использования.

По умолчанию Spring Boot настраивает физическое именованиеСтратегия с SpringPhysicalNamingStrategy.Эта реализация обеспечивает ту же структуру таблиц, что и Hibernate 4: все точки заменяются подчеркиванием, а верблюжий корпус также заменяется подчеркиванием.По умолчанию все имена таблиц создаются в нижнем регистре, но этот флаг можно переопределить, если ваша схема этого требует.

Попробуйте использовать следующее свойство в application.properties или application.yml, в зависимости от того, чтовы используете, чтобы Spring jpa не преобразовывал имя вашего столбца и использовал его так, как указано в вашей сущности.

Application.yml 

spring:
  jpa:
    hibernate:
      naming:
        physical-strategy: org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl
        implicit-strategy: org.hibernate.boot.model.naming.ImplicitNamingStrategyLegacyJpaImpl
