Spring Boot JPA - доступ к DialectResolutionInfo не может быть нулевым, если не задано значение hibernate.dialect

/ 15 февраля 2019

У меня есть приложение Spring Boot JPA.Всякий раз, когда я пытаюсь запустить его, происходит сбой: 

Caused by: org.hibernate.HibernateException: Access to DialectResolutionInfo cannot be null when 'hibernate.dialect' not set        at org.hibernate.engine.jdbc.dialect.internal.DialectFactoryImpl.determineDialect(DialectFactoryImpl.java:100) ~[hibernate-core-5.3.7.Final.jar:5.3.7.Final]

Я смотрел на связанные вопросы здесь, но большинство, похоже, относятся к проблемам, когда БД еще не запущена, неверные учетные данные и т. Д. Однако,Я могу нормально подключиться к клиенту PSQL, так что это не может быть проблемой.Я пробовал его как с платформой, так и без нее, указанной в моем приложении. Properties:

spring.datasource.url=jdbc:postgresql://xxxx/my_db
spring.datasource.username=xxx
spring.datasource.password=xxx
spring.jpa.show-sql=true
spring.datasource.driverClassName=org.postgresql.Driver
spring.jpa.database-platform=org.hibernate.dialect.PostgreSQLDialect

Кроме того, над ошибкой приложение фактически выводит следующее: 

2019-02-15 10:02:40.134  INFO 43204 --- [           main] org.hibernate.dialect.Dialect            : HHH000400: Using dialect: org.hibernate.dialect.PostgreSQL95Dialect

В чем может быть проблема?Это приложение действительно работало;однако я недавно переключил машины разработки и теперь не могу подключиться.Я отключил брандмауэр на своей машине, чтобы увидеть, может ли это быть проблемой, но безуспешно.Опять же, я могу подключиться через PSQL, поэтому я действительно не уверен, что думать.

Имя свойства в порядке, именно класс, который вы определили, вызывает проблему.PostgreSQLDialect устарело.Измените его, например: 

spring.jpa.database-platform = org.hibernate.dialect.PostgreSQL95Dialect

, что для postgres 9.5.Подробнее здесь .Если у вас есть другая версия postgres, вы можете найти правильную версию класса диалекта.

Когда я получаю «Доступ к DialectResolutionInfo не может быть нулевым, когда« hibernate.dialect »не установлен», выше этой ошибки, что-то еще не так, однажды я получил «sql.SQLSyntaxErrorException: доступ запрещен для пользователя« tenant2 »@ 'localhost' к базе данных 'tenant2'. Другой раз о "serverTimeZone". Так что мой ответ - посмотреть на ошибку выше, которая является вашей основной причиной.

Я полагаю, что вы неправильно указали свой диалект

spring.jpa.database-platform=org.hibernate.dialect.PostgreSQLDialect

должно быть

spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.PostgreSQLDialect
