“ xxxDAOImpl”中的现场会话需要找不到“ org.hibernate.SessionFactory”类型的Bean
问题内容:
我收到以下错误(我相信是Dao层-但我可能读错了)。
我现在有一个Spring
Boot应用程序,可以创建一个数据库模式。表格正在正确创建,但是当我尝试添加Dao和DaoImpl文件时,它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;
这是我的POM.xml文件的外观:

有谁知道如何解决这个问题?请让我知道,谢谢。
问题答案:
因此,我找到了适合我的解决方案。如果您正在使用配置.xml文件,则Mathias可能是正确的。但是对于那些使用application.properties文件的用户,您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:
spring.jpa.properties.hibernate.current_session_context_class=org.springframework.orm.hibernate4.SpringSessionContext
这个解决方案对我有用。这是我能够处理的其他参考:
