How to autowire Hibernate SessionFactory in Spring boot

Question

I've created a spring boot application, and I want to handle the Hibernate SessionFactory, so in my service class, I can just call the Hibernate SessionFactory as following :

@Autowired
private SessionFactory sessionFactory;

I found a similar question in stackoverflow where I have to add the following line in application.properties :

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

but I'm getting this error :

Cannot resolve property 'current_session_context_class' in java.lang.String

How can I solve this ?

pom.xml dependencies :

<dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-jpa</artifactId>
        </dependency>

    </dependencies>

Answer 1

Since version 2.0, JPA provides easy access to the APIs of the underlying implementations. The EntityManager and the EntityManagerFactory provide an unwrap method which returns the corresponding classes of the JPA implementation.

In the case of Hibernate, these are the Session and the SessionFactory.

SessionFactory sessionFactory = entityManagerFactory.unwrap(SessionFactory.class);

Try enabling HibernateJpaSessionFactoryBean in your Spring configuration.

@Bean
public HibernateJpaSessionFactoryBean sessionFactory() {
    return new HibernateJpaSessionFactoryBean();
}

By Spring configuration I mean a class annotated with @Configuration annotation or @SpringBootApplication (it is implicitly annotated with @Configuration).
