Group class has a collection of Member class. However, Member does not have direct reference to the Group. Hence, it is unidirectional 1:N. However, there is a twist to it that Member class contains the Group ID, so that standalone Member's can identify their own groups quickly, and in most case Group ids are only needed when dealing with members.
My problem is that I can get the group and member created in the db with cascase save on the group object. However, I wouldn't figure how to get the group id inside Member to be populated by hibernate automatically.
This only happen in save(). I know getting members from the db will have the group id set.
I know I can use bidirectional mapping to solve this problem. However, bidirectional mapping does not sound to me because
- my client and server are in two JVM. Hibernate proxy won't work without addtional works.
- I don't need the entire Group object in Member, and I don't want to serialize Group inside Member accidently if server needs to do some work before passing the Member object back.
- I don't want to have a proxy Group inside Member just for accessing the group ID. I know the group id is cached in the proxy class. However, just having the proxy there is intrusive and give clients a false assumption that group object may be accessible.
For now, to get around the problem, I need to manually populate the group id in each Member after doing a cascade save. If not, the Member with null group id will be cached, and cost other problem.
Does anyone know a better solution?
