Generate DDL with spring boot using a custom delimiter

Question

I want generate create and drop ddl scripts using spring boot v1.4.3 with JPA - Hibernate 5.0.11.

Most answers I found use the javax.persistence.schema-generati

Answer 1

What I found out is that the sessionFactoryholds the schemaExport values like createSQL, dropSQL, outputFile and delimiter.

The sessionFactory as a Bean can be created like that and is then available for autowiring:

....

@Autowired
private EntityManagerFactory entityManagerFactory;

@Bean
public SessionFactory sessionFactory() {
    if (entityManagerFactory.unwrap(SessionFactory.class) == null) {
        throw new NullPointerException("factory is not a hibernate factory");
    }
    return entityManagerFactory.unwrap(SessionFactory.class);
}

That is not a working solution but could help you to manually configure the schemaExport using sessionFactory. I dont find a solution for just using the properties and setting the delimiter just there. But could be a little helper for finding the working solution.

If I find more useful infos I will update my answer.
