Incrementing an "Assigned" type ID

aforsyth · **Posted:** Mon Dec 12, 2005 12:23 pm

Hi:

Can anyone provide me an example of incrementing the "id" when the mapping file has it defined as assigned? I'm having problems understanding the IncrementGenerator.generate() method and how this is used with the following mapping file and PO.

Thanks, Alex.

Hibernate version:
2.1.6

Code:

<hibernate-mapping>
    <class
        name="com.telus.ccs.adminRouting.model.po.SkillsetSiteAssociationAdmin

        dynamic-insert="false"
    >

IncementGenerator.generate() method is not used by the mapping. I guess the annotations in the class file are for XDoclet, but I am afraid that it did not do a very good job in this case.

Assigned means that our code have to take care of assigning ID to object and calling appropriate method (save() or update()) to persist the object.
