Does anyone know how to get a handle the Hibernate SessionFactory that is created by Spring Boot

User · Answer

If it s really required to access SessionFactory through  Autowire  I d rather configure another EntityManagerFactory and then use it to configure the SessionFactory bean  like following    Configuration public class SessionFactoryConfig     Autowired  DataSource dataSource    Autowired JpaVendorAdapter jpaVendorAdapter    Bean  Primary public EntityManagerFactory entityManagerFactory         LocalContainerEntityManagerFactoryBean emf   new LocalContainerEntityManagerFactoryBean        emf setDataSource dataSource       emf setJpaVendorAdapter jpaVendorAdapter       emf setPackagesToScan  com hibernateLearning        emf setPersistenceUnitName  default        emf afterPropertiesSet        return emf getObject        Bean public SessionFactory setSessionFactory EntityManagerFactory entityManagerFactory        return entityManagerFactory unwrap SessionFactory class

The simplest and least verbose way to autowire your Hibernate SessionFactory is   This is the solution for Spring Boot 1 x with Hibernate 4   application properties   spring jpa properties hibernate current session context class  org springframework orm hibernate4 SpringSessionContext   Configuration class    Bean public HibernateJpaSessionFactoryBean sessionFactory         return new HibernateJpaSessionFactoryBean        Then you can autowire the SessionFactory in your services as usual    Autowired private SessionFactory sessionFactory    As of Spring Boot 1 5 with Hibernate 5  this is now the preferred way   application properties   spring jpa properties hibernate current session context class  org springframework orm hibernate5 SpringSessionContext   Configuration class    EnableAutoConfiguration          Bean public HibernateJpaSessionFactoryBean sessionFactory EntityManagerFactory emf        HibernateJpaSessionFactoryBean fact   new HibernateJpaSessionFactoryBean        fact setEntityManagerFactory emf       return fact

It works with Spring Boot 2 1 0 and Hibernate 5   PersistenceContext private EntityManager entityManager    Then you can create new Session by using entityManager unwrap Session class   Session session   null  if  entityManager    null         session   entityManager unwrap Session class      null         throw new NullPointerException        example create query   session createQuery  FROM Student      application properties   spring datasource driver-class-name oracle jdbc driver OracleDriver spring datasource url jdbc oracle thin  localhost 1521 db11g spring datasource username admin spring datasource password admin spring jpa show-sql true spring jpa hibernate ddl-auto create-drop spring jpa properties hibernate dialect org hibernate dialect Oracle10gDialect

Another way similar to the yglodt s  In application properties   spring jpa properties hibernate current session context class org springframework orm hibernate4 SpringSessionContext   And in your configuration class    Bean public SessionFactory sessionFactory HibernateEntityManagerFactory hemf        return hemf getSessionFactory        Then you can autowire the SessionFactory in your services as usual    Autowired private SessionFactory sessionFactory

You can accomplish this with  SessionFactory sessionFactory        entityManagerFactory unwrap SessionFactory class    where entityManagerFactory is an JPA EntityManagerFactory  package net andreaskluth hibernatesample   import javax persistence EntityManager  import javax persistence EntityManagerFactory   import org hibernate Session  import org hibernate SessionFactory  import org hibernate Transaction  import org springframework beans factory annotation Autowired  import org springframework stereotype Component    Component public class SomeService      private SessionFactory hibernateFactory      Autowired   public SomeService EntityManagerFactory factory        if factory unwrap SessionFactory class     null         throw new NullPointerException  quot factory is not a hibernate factory quot              this hibernateFactory   factory unwrap SessionFactory class

Great work Andreas   I created a bean version so the SessionFactory could be autowired   import javax persistence EntityManagerFactory  import org hibernate SessionFactory  import org springframework beans factory annotation Autowired  import org springframework context annotation Bean          Autowired private EntityManagerFactory entityManagerFactory    Bean public SessionFactory getSessionFactory         if  entityManagerFactory unwrap SessionFactory class     null            throw new NullPointerException  factory is not a hibernate factory              return entityManagerFactory unwrap SessionFactory class
