2 questions about Hibernate Annotations

sven · **Posted:** Sun Aug 07, 2005 6:23 pm

Is there any possibility to label the foreign key constraints together with Hibernate Annotations? With XML mappings I used the attribute foreign-key.

Example:

Code:

<many-to-one name="role"
class="Role"
column="rolename"
not-null="true"
foreign-key="fk_users_rolename"/>

What about the inverse="false|true" in XML mappings. Is there something similar with Hibernate Annotations?

Thanks in advance,
Sven

Hi Sven!
I am experimenting annotation. So far I didn't need the

foreign-key label

tag.
I will look for it, and then I will reply again.

I suggest you to download the ejb3 specification (if you haven't already done it)

Does this refer to my question about foreign key name, to my question about inverse="true|false" or to both? :)

Well I tried to avoid too much keystrokes ;-)

The foreign key name is not implemented yet.
inverse=true/false is replaced by the mappedBy notion (if mappedBy is set, then it means inverse="true").
I've not tried a bi-dir one-to-many when the @OneToMany has no mappedBy, but I guess it works if you set the many to one side as insertable=false updatable=false.

Thanks for the clarification. :)
