Hi,

I have two classes, Item and Order mapped as One-to-Many such as:



My Order class only have an identifier to the Item class, it does not have a getItem(), only a getItemId(). The association is one to many because that is what it is actually like.

I would like to be able to provide Hibernate with a set of Orders that I have previously loaded. I have enabled second level cache, and it works fine the second time around, but on the very first load (ie nothing in the cache), I would like Hibernate not to fetch my Order to populate my collection. Instead, I want to provide it with the ones that I know for sure are linked to it. Is there a certain way to achieve this? My attempts at not using the CascadeType.REFRESH attribute to try and do this have not worked. Would a many-to-many association work better?

Any help would be appreciated.

Regards,

Greg

When you don't want that Hibernate immediately load's the orders belonging to an item, then you should not
define fetch = FetchType.EAGER on the @OneToMany relation.



I don't understand exactly what you mean here.
Do you want to fill the collection partially?

No I want to fill the collection fully but I don't want Hibernate to do it. My issue is that when I defined the FetchType as lazy, the collection was not loaded but the moment I was trying to set it manually (ie as soon as getWindows() is called on the Room object), that triggered the load from the DB. Basically I would love to be able to tell Hibernate that I'm giving that collection manually but that it should still be able to: cache it; perform merge/remove/persist operations for me.

But I understand that this might not be possible.

Greg
