Question

I have two class

Class Item
{
   private Auction CorrespondingAuction;
}

Class Auction
{
    private Item CurrentItem;
}

Can someone tell how to set this one to one mapping in XML, it must be bidirectional

Answer 1

In Auction XML FILE:

 <many-to-one name="CurrentItem" class="com.BiddingSystem.Models.Item" fetch="join"
            not-null="true" cascade="all" unique="true" lazy="false">
            <column name="CURRENTITEM" />
 </many-to-one>

In Item XML File:

<one-to-one name="auction" class="com.BiddingSystem.Models.Auction" property-ref="CurrentItem"/>

property-ref refers to the name of the variable corresponding to class item in the auction class
