ManyToOne with @Formula mapping instead of @Joincolumn ?

I was just wondering if this support is in hibernate annotations yet ?
I can't seem to find it ...

I have a working version with xml mapping files that contain this :

Code:

      <many-to-one name="opsmode"
         class="com.watchtalk.web.businessobject.OperationalMode"
         update="false" insert="false">
         <column name="OPSMODE" length="2" />
         <formula>'OPSMODE'</formula>
         <formula>'0'</formula>
      </many-to-one>

That works fine.

Now is there a way to get the same bahviour with annotations ?
Something like :

Code:

    @ManyToOne 
    @JoinColumns ( 
        {
           @JoinColumn ( formula="SUBSTR(APPLMODID, 0, 2)", referencedColumnName = "TYPE" )
            ,@JoinColumn ( formula="SUBSTR(APPLMODID, 2, 4)", referencedColumnName = "NAME" )
            ,@JoinColumn ( name="message" , referencedColumnName = "messageid" )
        }
    )
    public Logmessage getMessage() {
        return message;
    }

Is this supported yet ?

no, unfortunately this is not supported yet. A contribution would be welcome though :-)
