再次感谢您的帮助，id为entityManagerFactory的bean应该实现接口：

javax.persistence.entityManagerFactory

但是您的

entityManagerFactory

类型为

org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean

，并且它没有实现

entityManagerFactory

顺便说一句，我觉得你混合了JPA和纯Hibernate（而不是Hibernate的JPA部分）。那是行不通的。我建议使用JPA和Hibernate作为JPA提供程序

您能给我一些示例或教程来说明如何使用Hibernate作为JPA提供程序吗？我还混合了JPA和纯Hibernate。@woyaru：对不起，我没有教程。但是要看到JPA/Hibernate的运行，您可以创建一个SpringRoo项目，它非常好地展示了JPA/Hibernate是如何工作的。
