A typical JPA entity looks like:

@Entity
public class Person {
@Id
private int id;
private String name;
private int age;
private Calendar anniversary;
...
}
Note that the data type is not annotated on any of the member attributes.

I just read a note around Hibernate being not so usable with Scala's data types and wondered if we could write some adaptors. I know we can write UserTypes for Scala types and UserCollectionTypes for Scala's collections so adaptors may be possible.

The question I have is can I configure these data types somehow so JPA will automatically associate them with corresponding Scala types (e.g. BigDecimal's user type with BigDecimal attributes), without having to annotate each attribute with @Type?

or is there an out-of-the-box solution available for scala types anyways?

is there a way/ forum to seek answers to such questions that don't get answered for some time? e.g. from the contributors to the hibernate source code?
