试着清理你的日食，对我来说很有效
转到cmd并执行eclipse-clean查看堆栈跟踪中的最终原因：这是一个标准类路径问题。用XML配置再次检查类名；它们区分大小写。类etudiandi是使用hibernate Toolsys从数据库自动生成的，但我没有etudiandi.hbm.xml，因为它只用于person和etudiant类之间的关系。问题是“因为缺少此关系”。自动生成的etudiandi.class是否使用anotation？你能发布那个类吗？也许我还有一个问题是关联引用未映射的类：com.GestionEtudiant.model.UserWorked也为我工作。谢谢@sagar
