Qualified bean must be of 'EntityManagerFactory' type in Spring Boot 3. Works with Spring-CodePudding

I'm currently upgrading my project to Spring Boot 3 using a own JpaTransactionmanager configuration.

My code looks like following snippet:

@Configuration
@EnableJpaRepositories(
    entityManagerFactoryRef = "myEntityManagerFactory",
    transactionManagerRef = "myTransactionManager"
)
public class MyPersistenceConfig {

    ...

    @Bean
    public LocalContainerEntityManagerFactoryBean myEntityManagerFactory(DataSource dataSource) {
        var emfBean = new LocalContainerEntityManagerFactoryBean();

        // Some configuration removed

        return emfBean;
    }

    @Bean
    public JpaTransactionManager myTransactionManager(@Qualifier("myEntityManagerFactory") EntityManagerFactory emf) {
        var transactionManager = new JpaTransactionManager();
        transactionManager.setEntityManagerFactory(emf);
        return transactionManager;
    }
}

However, this code works in latest Spring Boot 2 but not with Spring Boot 3. Following (minimized) error is thrown on startup:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'myEntityManagerFactory' defined in class path resource [<path>/<to>/MyPersistenceConfig.class]: Unable to resolve name [org.springframework.boot.orm.jpa.hibernate.SpringPhysicalNamingStrategy] as strategy [org.hibernate.boot.model.naming.PhysicalNamingStrategy]

...

Besides IntelliJ says on the JpaTransactionManager-Bean: Could not autowire. Qualified bean must be of 'EntityManagerFactory' type..

According the LocalContainerEntityManagerFactoryBean-JavaDoc, it should produce a EntityManagerFactory-Bean (and actually did with Spring-ORM 5):

FactoryBean that creates a JPA EntityManagerFactory according to JPA's standard container bootstrap contract.

Is there anything that I'm missing?

CodePudding user response：

The problem seems to be the org.springframework.boot.orm.jpa.hibernate.SpringPhysicalNamingStrategy which has been deprecated since Spring Boot 2.6 and removed in Spring Boot 3 in favor of the CamelCaseToUnderscoresNamingStrategy.
