如果已在EtudiantId.hbm.xml中定义了com.GestionEtudiant.model.EtudiantId的映射 将其添加到＆＃34; mappingResources＆＃34;像这样
<property name="mappingResources">
<list>
...
<value>com/GestionEtudiant/model/EtudiantId.hbm.xml</value>
...
<强>更新： -
如果您的自动生成的类使用注释，请添加packagesToScan属性，如下所示
<bean id="sessionFactory"
<property name="packagesToScan" value="com.GestionEtudiant.model" />

尝试清理你的日食。它对我有用。
GoTo cmd并执行 eclipse -clean
答案 2 :(得分：0)
类com.GestionEtudiant.model.EtudiantId需要位于类路径中。它是否部署在war文件中？
