spring.jpa.hibernate.ddl-auto = create在带有SpringBoot 2.0的Hibernate 5中不起作用

Question

I created a SpringBoot 1.5.11.RELEASE and Hibernate 5 project . Everything was working fine.

However, when I changed SpringBoot version to 2.0.0.RELEASE the spring.jpa.hibernate.ddl-auto=create does not work. I have tried this stackoverflow post , but no luck.

Here is the stack trace of SpringBoot 1.5.11.RELEASE :

In Boot 2.0 stack trace the below part does not appear :

Running hbm2ddl schema export Hibernate: drop table if exists person Hibernate: create table person (id integer not null auto_increment, name varchar(255), primary key (id))

Answer 1

As mentioned by M.Deinum I've deleted the following classes and resource file and it works :

• HinernateConfig
• hibernate.cfg.xml

And changes in Main application

@SpringBootApplication
public class Hibernate5Application implements CommandLineRunner {

    private EntityManagerFactory managerFactory;

    public Hibernate5Application(EntityManagerFactory managerFactory) {
        this.managerFactory = managerFactory;
    }

    public static void main(String[] args) {
        SpringApplication.run(Hibernate5Application.class, args);
    }

    @Override
    @Transactional
    public void run(String... args) throws Exception {
        EntityManager entityManager = managerFactory.createEntityManager();
        entityManager.getTransaction().begin();
        Person person = new Person("Mehraj Malik");
        entityManager.persist(person);
        System.out.println("Saved!!");
        entityManager.close();
    }
}
