[hibernate-issues] [Hibernate-JIRA] Commented: (ANN-640) use property names defined in CompositeUserType as default column names

use property names defined in CompositeUserType as default column names ----------------------------------------------------------------------- Key: ANN-640 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-640 Project: Hibernate Annotations Issue Type: New Feature Affects Versions: 3.3.0.ga 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
