Bonjour,
j'ai un soucis concernant l'insertion dans la base de donnée, en effet, j'ai 3 classes, une classe Employe qui herite de Person et une derniere classe qui s'appele Description. lors de l'insertion, il n'insert que Person et Employe dans la base.
PS. le select le fait sans aucun probleme
le code hbm de des deux premieres classes (Person et Employe) est :
Code:
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping
package="xxx.object">
<class name="Person" table="PERSON"
optimistic-lock="version">
<id name="oid" column="OID">
<generator class="uuid" />
</id>
<version name="timestamp" column="TIMESTAMP" type="long"
generated="always" unsaved-value="null" />
<joined-subclass name="Employe"
table="EMPLOYE">
<key column="OID" />
<property name="collective" column="COLLECTIVE"
type="boolean" />
<one-to-one name="description"
class="Description" cascade="all" />
</joined-subclass>
</class>
</hibernate-mapping>
et le code hbm de la classe Desciption
Code:
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping
package="xxx.object">
<class name="Description"
table="DESCRIPTION" optimistic-lock="version">
<id name="oid" column="OID">
<generator class="foreign">
<param name="property">employe</param>
</generator>
</id>
<version name="timestamp" column="TIMESTAMP" type="long"
generated="always" unsaved-value="null" />
<property name="name" column="NAME" type="java.lang.String" />
<one-to-one name="employe"
class="Employe" constrained="true" />
</class>
</hibernate-mapping>
