Composite foreign key columns in GORM

Question

I need to customize the column names for composite foreign keys in GORM, and I didn't find any document that shows how to do it. I know how to customize PK columns, and how to customize a single-column FK, but not multi-column FK. Is it possible at all?

Thanks.

Answer 1

A domain class with composite id must implement the Serializable interface.

class Person implements Serializable {
...
}
