I have the following Domain objects:

-Person
-Address
- Mailing Address
- Home Address

Mailing address and Home address inherit from Address. A Person can only have one Mailing Address and only one Home Address. Hence, it makes sense for there to be a mapping that retrieves a Set of addresses. It also makes sense for there to be a mapping to get/set a Home Address since there is only one of them.

The addresses are all in the same table, hence I am using table per class hierarchy. The discriminator column is only used to mark what kind of address it is.

What is the best way of dealing with this?

My first approach is to have the somthing like the following:



Of course the getter would need to do similar logic.


This doesn't seem to be correct to me. Has anyone else delt with this?


thanks

I'm having a similar problem. Did you find a solution for this?

I've gone ahead and used the solution I outlined above. It seems to work, but it still seems very wrong to me.

Another way to do this is to have a one-to-one mapping in the hbm file for each of the addresses. Then you could have a getAddresses() method like the following:




I think this is kind of strange too, but it's another way of doing it. I don't know which way would be the "correct" way of doing it.

I agree with you. It does look a little strange. I wonder if we could get some others to comment on these two approaches.
