我导入的包
ejb3-persistence.jar
hibernate-commons-annotations.jar
hibernate-jpa-2.0-api-1.0.1.Final.jar
hibernate-annotations.jar










把 SessionFactory sessionFactory =new Configuration().configure().buildSessionFactory();改为
SessionFactory sessionFactory =new AnnotationConfiguration().configure().buildSessionFactory();出现下面错误
