Persist only base class's fields at hibernate

Question

I have a base class and some class which extends the base class. Due to the fields of the extending class used for other purpose and for the db, I want to persist only the base class field, how can I do it? Is there an annotation that do it?
Note that I don't want to use @Transient for each new field I crate.

如果只想保留基类对象，则只需创建基类实体而不是子类实体并保存。
