Question

建立我的第一个Spring4.2.5 + Hibernate4.3.11项目

我想我只需要一双新眼睛来看看我的设置有什么问题。我几乎一步一步地遵循文档和其他教程。提前谢谢。

当我编译我得

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'bookDao': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private org.hibernate.SessionFactory com.app.books.BookDao.sessionFactory; nested exception is java.lang.NoClassDefFoundError: org/hibernate/boot/model/naming/ImplicitNamingStrategy

在堆栈的底部，原因是

Caused by: java.lang.ClassNotFoundException: org.hibernate.boot.model.naming.ImplicitNamingStrategy

我几乎检查了所有我不知道是什么导致下面找不到的课程是我的代码。

Answer 1

您主要复制并粘贴会话工厂配置，但没有注意到hibernate 5的引用。

class="org.springframework.orm.hibernate5.LocalSessionFactoryBean"

更好地转向Hibernate 5.
