Hibernate Federated Primary Key Composite-id mapping, querying for single primary key issues

Today the project encountered this problem, engaged in the majority of days, now recorded
Hibernate Federated Primary Key configuration (multiple fields together as primary key)

<classname= "COM.CSKJ.HIBERNATE.MAP.BBWJJC"Table= "BB_WJJC"Schema= "dbo"Catalog= "WJGL">        <Composite-idname= "id"class= "Com.cskj.hibernate.map.BbWjjcId">            <Key-propertyname= "Wjtmid"type= "Java.lang.Long">                <columnname= "Wjtmid" />            </Key-property>            <Key-propertyname= "Wjxxid"type= "Java.lang.Long">                <columnname= "Wjxxid" />            </Key-property>            <Key-propertyname= "Wjzxxid"type= "Java.lang.Long">                <columnname= "Wjzxxid" />            </Key-property>            <Key-propertyname= "Wjztmid"type= "Java.lang.Long">                <columnname= "Wjztmid" />            </Key-property>            <Key-propertyname= "Wjid"type= "Java.lang.Long">                <columnname= "Wjid" />            </Key-property>        </Composite-id>

Generate files for primary keys

 Public class Implements   Private privateprivate private   Private  Long Wjid; }

Use the HQL statement when querying a single primary key

From BBWJJC bw where bw. Bbwjjcid.wjid=?
Result Error:
Could not resolve Property:bbwjjcid OF:COM.CSKJ.HIBERNATE.MAP.BBWJJC [from COM.CSKJ.HIBERNATE.MAP.BBWJJC bw where bw. Bbwjjcid.wjid= ' 5 ']

On the internet to check a bit, said is the problem of HQL statement.
Test the most of the day results debugging is normal, the original is bw. Bbwjjcid.wjid=? The bbwjjcid in the mapping XML to write the name (ie: ID), cannot write the PK class name.
Right Hql:from BBWJJC bw where bw.id.wjid=? Hard to fix!!!
