Xavier Dury commented on HHH-4347:
----------------------------------
please, some smart defaults would be very nice to have =) I think many people are using
hibernate as their main jpa implementation because of all the useful things not covered by
the specification... and user types are one of them. For my part, I have a composite user
type for joda-time intervals and it would be nice if I wasn't forced to put @Columns
everywhere.
use property names defined in CompositeUserType as default column
names

Key: HHH-4347
URL:
http://opensource.atlassian.com/projects/hibernate/browse/HHH-4347
Project: Hibernate Core
Issue Type: New Feature
Components: annotations
Reporter: Michael Newcomb
Priority: Minor
Consider:
public class LongitudeLatitude
{
protected double longitude;
protected double latitude;
}
public class LongitudeLatitudeCompositeUserType
implements CompositeUserType
{
public String[] getPropertyNames()
{
return new String[] { "longitude", "latitude" };
}
public Type[] getPropertyTypes()
{
return new Type[] { Hibernate.DOUBLE, Hibernate.DOUBLE };
}
...
}
@Entity
public class Test
{
@Basic(optional = false)
@Type(type = "foo.bar.LongitudeLatitudeCompositeUserType")
@Columns(columns = { @Column(name = "location_longitude"), @Column(name =
"location_latitude") })
protected LongitudeLatitude location;
}
Why does the developer need to specify each column?
I'd really rather let the CompositeUserType take care of that for me. Now, I have to
tie the @Columns to the # of properties in my CompositeUserType AND the order in which
they are defined? This seems to defeat the purpose of having a class (CompositeUserType)
to tell Hibernate how to store it.
Couldn't Hibernate prepend the property name 'location' and '_' to
the front of each property name in the CompositeUserType?
Perhaps (more than likely) I'm doing something wrong, but I get a failure if I do not
specify the columns.
Thanks,
Michael
