mysql primary key can not auto_increment

[fank243]

I am using a MySQL database. The table I created is self-growth. The mapped java entity inherits the play.db.jpa.Model class, but when I call the .save() method to save it to the database, The primary key ID is generated by hibernate_sequence, not by the table AUTO_INCREMENT.

If you are using Hibernate 5.x, try the following in application.conf:
hibernate.id.new_generator_mappings=false
