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

Question

I am getting the following error (from I believe, the Dao layer - but I could be reading this wrong).

I have a Spring boot app that right now, creates a DB schema. The tables are being create properly but when I tried adding the Dao and DaoImpl files, it crashes with the error message below:

***************************
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.

In my DaoImpl file, I have:

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

Here's how my POM.xml file looks:

Does anyone have any idea as to how I fix this? Please let me know, thanks.

Answer 1

So I found a solution that works for me. Mathias was probably right if you are working with a configuration .xml file. But for those who are using an application.properties file, you need to add this line to your configuration class or main application class:

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

Once done, add this line to the application.properties file:

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

This solution worked for me. Here are additional references that I was able to work off of:
