java - 创建名称为 'sessionFactory' 的 bean 时出错无法实例化默认 tuplizer [org.hibernate.tuple.entity.PojoEntityTuplizer]

Question

我正在使用 Hibernate 和 spring 以及 apach tomcate 开发一个应用程序

将此文件 Utilisateur.java 与 Utilisateur.hbm.xml 进行比较。

• 检查两个文件中的属性名称是否相同
• 在 Utilisateur.java 中包含一个默认构造函数
• 您可能会错过这个 jar 文件。 javassist.jar

当您遇到此错误时 无法实例化默认 tuplizer [org.hibernate.tuple.entity.PojoEntityTuplizer]。这是一条通用消息。所以你必须查看导致错误的最后一行。这可能是解决方案。
