'xxxDAOImpl中的字段会话需要一个无法找到'org.hibernate.SessionFactory'类型的bean

Question

我收到以下错误(从我相信,Dao层 - 但我可能会读错了).

我现在有一个Spring启动应用程序,创建一个数据库架构.这些表正在正确创建,但是当我尝试添加Dao和DaoImpl文件时,它会崩溃,并显示以下错误消息:

***************************
APPLICATION FAILED TO START
***************************

Description:

Field session in xx.dao.ParkingSpaceDaoImpl required a bean of type 'org.hibernate.SessionFactory' that could not be found.


Action:

Consider defining a bean of type 'org.hibernate.SessionFactory' in your configuration.

在我的DaoImpl文件中,我有:

@Repository 
public class xxDaoImpl implements xxDao {
    @Autowired
    private SessionFactory session;

以下是我的POM.xml文件的外观:

有没有人知道我如何解决这个问题？请让我知道,谢谢.

Answer 1

所以我找到了适合我的解决方案.如果您正在使用配置.xml文件,Mathias可能是正确的.但对于那些使用application.properties文件的用户,需要将此行添加到配置类或主应用程序类中:

@Bean  
public SessionFactory sessionFactory(HibernateEntityManagerFactory hemf){  
    return hemf.getSessionFactory();  
}   

完成后,将此行添加到application.properties文件中:

spring.jpa.properties.hibernate.current_session_context_class=org.springframework.orm.hibernate4.SpringSessionContext

这个解决方案对我有用.以下是我能够解决的其他参考资料:
