What I guess is the problem is that I cannot express *composite key as
an BillItemId object* on the BillItem class and I guess I will need own
TypeHandler for whole Bill class.
This works for me:
<resultMap id="billResultMap" type="Bill">
<id column="bill_id" property="id" />
<collection property="billItems" javaType="ArrayList" ofType="BillItem">
<id column="bill_id" property="idBill"/>
<id column="bi_item_order" property="itemOrder" />
<result column="bi_sku" property="customId" />
<result column="bi_name" property="name" />
...
</collection>
</resultMap>
The separate BillItemId class is unnecessary.
