Part of Composite-Id is foreign Key:How specify in Mapping?
-----------------------------------------------------------
Key: HHH-4012
URL:
http://opensource.atlassian.com/projects/hibernate/browse/HHH-4012
Project: Hibernate Core
Issue Type: Improvement
Components: core
Affects Versions: 3.3.2
Reporter: Sandeep Vaid
Priority: Critical
I have 2 classes viz. Product and ProductBasic having one-to-one relationship
class Product{
String productId;
ProductBasic productBasic;
}
class ProductBasic{
String productId;
String useCode;
TimeStamp startTime;
Product product;
}
Product is mapped to a table PRODUCT which has PRODUCTID as PK.
ProductBasic is mapped to a table PRODUCTBASIC which has PRODUCTID,USECODE and
STARTTTIME as composite key.
Also PRODUCTID (of PRODUCTBASIC table) is the foreign key referencing PRODUCT table...
How can i define my one-to-one mapping considering ProductBasic.productId should get its
value from Product.productId ?
<composite-id>
<key-property name="productId" column="PRODUCTID"
type="string" length="10" />
<key-property name="useCode" column="USECODE"
type="string" length="10" />
<key-property name="startTime" column="STARTTIME" />
<composite-id>
In this only productId is the foreign key..
I am aware that i can use a <generator> tag (with class="foreign")
inside <composite-id> but i guess it will generate the
value for entire composite-id and not just a field of it.
