Hibernate工具Pojo Generation默认使用Set

Question

Hibernate tools Pojo Generation uses java.util.Set by default. I want to generate POJO's with java.util.List instead of java.util.Set. Is there any way ?

Answer 1

If you're using HBM files, you can use <bag> or <list> instead of <set>

Check Hibernate documentation at : http://docs.jboss.org/hibernate/core/3.5/reference/en/html/collections.html#collections-mapping

Answer 2

Actually, Hibernate creates mapping on your database structure. I have one to many mapping without index column so it generates 'Set' which is correct for non indexed one to many mapping.
