Get column name of property mapped with Hibernate

Question

How can I access the Hibernate mapping of my model to find out the column name of a property?

The column name is not specified in the mapping so Hibernate generates

Answer 1

This will retrieve one-level composites and normal property mappings:

String columnName(String name) {
    PersistentClass mapping = configuration.getClassMapping(ExtendedPerson.class.getName());
    Property property = mapping.getProperty(name);
    if(property.isComposite()){
        Component comp = (Component) property.getValue();
        property = comp.getProperty(StringHelper.unroot(name));
        assert ! property.isComposite(); //go only one level down 
    }
    Iterator columnIterator = property.getColumnIterator();
    Column col = (Column) columnIterator.next();
    assert ! columnIterator.hasNext();
    return col.getName();
}
