In Spring Boot, spring.jpa.properties points to a Map, so it can only contain String values.

However in Hibernate, when the EntityManagerFactoryBuilderImpl reads hibernate.integrator_provider it expects to find an instance of IntegratorProvider and not a Class name, hence the exception.

You can however add a bean that implements HibernatePropertiesCustomizer to add the IntegrationProvider instance to the Hibernate properties:

@Component
public class HibernateConfig implements HibernatePropertiesCustomizer {

    @Override
    public void customize(Map hibernateProperties) {
        hibernateProperties.put("hibernate.integrator_provider",
                (IntegratorProvider) () -> Collections.singletonList(MetadataExtractorIntegrator.INSTANCE));
    }
}

I have created a working example in this repository.
