Spring Boot проект строится успешно и выдает ошибку

Question

Я пробовал так много раз с бесчисленными поисками в Google. Но это не сработает. Это дает исключение BeanCreationException.

Answer 1

Я полагаю (поскольку вы не опубликовали свое определение сущностей), что ваш класс "Entity" использует @GeneratedValue() без указания последовательности (имени генератора) для использования. Таким образом, Hibernate использует имя по умолчанию: hibernate_sequence.

. Вы можете указать имя последовательности как часть аннотации GeneratedValue (через атрибут генератора)

@GeneratedValue(strategy=SEQUENCE, generator="entity_sequence")

Answer 2

После публикации этого вопроса я попытался изменить несколько файлов. Итак, наконец я получил ответ. Мне удалось решить эту проблему, изменив файл application.properties.

У меня есть application.properties, ранее

spring.datasource.username = root
spring.datasource.password = ****

spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL57InnoDBDialect
spring.jpa.hibernate.naming.physical-strategy=org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl

spring.jpa.show-sql = false
spring.jpa.hibernate.ddl-auto=validate

The correct application.properties file,
```spring.datasource.url = jdbc:mysql://localhost:3306/Register
spring.datasource.username = root
spring.datasource.password = 1234

spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL57InnoDBDialect
spring.jpa.hibernate.naming.physical-strategy=org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl

spring.jpa.show-sql = false
spring.jpa.hibernate.ddl-auto=update

Answer 3

Я не эксперт JPA, но похоже, что когда вы запускаете проект (mvn spring-boot:run), он подключается к базе данных и выполняет проверку схемы. Проверка схемы - это процесс, который гарантирует, что сущности, определенные в вашем проекте, действительно могут быть сопоставлены с соответствующими объектами базы данных: таблицами, последовательностями и т. Д.

Поскольку нет таблицы hibernate_sequence, весь процесс завершается неудачно потому что spring boot / hibernate «думает», что БД не находится в «рабочем» состоянии и не может использоваться с проектом.

Это поведение можно настроить с помощью свойства spring.jpa.hibernate.ddl-auto=<value> в application.properties / yaml

Возможные значения:

• нет
• проверить
• обновить
• создать-удалить

Читайте о них здесь например
