somewhere in your config you have a property called
hibernate.hbm2ddl.autoset to the valuecreateorcreate-drop. Just delete that property or assign the valuedo_nothing.If you set that property to an invalid value (such as
do_nothing), hibernate doesn’t do anything.You can check the documentation of that property here.
