Hibernate custom schema creation

Question

create creates a new database schema and update

Answer 1

You could disable the hibernate.hbm2ddl.auto option, check the conditions (probably using plain JDBC) and call (or don't) the create method of the SchemaExport class. This would be done in your application's initialization code (a ServletContextListener in case you are working with a web app).

An example on how to use the SchemaExport class:

AnnotationConfiguration config = new AnnotationConfiguration();
config.addAnnotatedClass(info.ems.models.User.class);
config.addAnnotatedClass(info.ems.models.Role.class);
config.configure();
new SchemaExport(config).create(true, true);
