Is the buildSessionFactory Configuration method deprecated in Hibernate

Question

When I updated the Hibernate version from 3 6 8 to 4 0 0  I got a warning about deprecated method buildSessionFactory   in this line   private static final SessionFactory sessionFactory            new Configuration   configure   buildSessionFactory      the Javadoc recommends using another method   buildSessionFactory ServiceRegistry serviceRegistry   but in the documentation I found deprecated variant     Can you help me with this little misunderstanding

I edited the method created by batbaatar above so it accepts the Configuration object as a parameter:

    public static SessionFactory createSessionFactory(Configuration configuration) {
        serviceRegistry = new StandardServiceRegistryBuilder().applySettings(
                configuration.getProperties()).build();
        factory = configuration.buildSessionFactory(serviceRegistry);
        return factory;
    }

In the main class I did:

    private static SessionFactory factory;
    private static Configuration configuration 
    ...      
    configuration = new Configuration();
    configuration.configure().addAnnotatedClass(Employee.class);
    // Other configurations, then           
    factory = createSessionFactory(configuration);

If anyone here after updating to 5 1 this is how it works  StandardServiceRegistry registry   new StandardServiceRegistryBuilder   configure   build                    MetadataSources sources   new MetadataSources registry                   Metadata metadata   sources getMetadataBuilder   build                    sessionFactory   metadata getSessionFactoryBuilder   build      instead of the below in hibernate 4 3   ServiceRegistry serviceRegistry   new ServiceRegistryBuilder   applySettings              configuration getProperties     buildServiceRegistry        sessionFactory   configuration buildSessionFactory serviceRegistry

here are many APIs deprecated in the hibernate core framework   we have created the session factory as below   SessionFactory sessionFactory   new Configuration   configure   buildSessionFactory      The method buildSessionFactory is deprecated from the hibernate 4 release and it is replaced with the new API  If you are using the hibernate 4 3 0 and above  your code has to be    Configuration configuration   new Configuration   configure    StandardServiceRegistryBuilder builder   new StandardServiceRegistryBuilder   applySettings configuration getProperties     SessionFactory factory   configuration buildSessionFactory builder build       Class ServiceRegistryBuilder is  replaced by StandardServiceRegistryBuilder from 4 3 0  It looks like there will be lot of changes in the 5 0 release  Still there is not much clarity on the deprecated APIs and the suitable alternatives to use  Every incremental release comes up with more deprecated API  they are in way of fine tuning the core framework for the release 5 0

If you are using Hibernate 5 2 and above then you can use this     private static StandardServiceRegistry registry    private static SessionFactory sessionFactory     public static SessionFactory getSessionFactory         if  sessionFactory    null          try              Creating a registry         registry   new StandardServiceRegistryBuilder   configure  hibernate cfg xml   build                Create the MetadataSources         MetadataSources sources   new MetadataSources registry               Create the Metadata         Metadata metadata   sources getMetadataBuilder   build                Create SessionFactory         sessionFactory   metadata getSessionFactoryBuilder   build             catch  Exception e            e printStackTrace            if  registry    null              StandardServiceRegistryBuilder destroy registry                               return sessionFactory           To shut down  public static void shutdown         if  registry    null          StandardServiceRegistryBuilder destroy registry

Yes it is deprecated  Replace your SessionFactory with the following   In Hibernate 4 0  4 1  4 2  private static SessionFactory sessionFactory  private static ServiceRegistry serviceRegistry   public static SessionFactory createSessionFactory         Configuration configuration   new Configuration        configuration configure        ServiceRegistry serviceRegistry   new ServiceRegistryBuilder   applySettings              configuration getProperties     buildServiceRegistry        sessionFactory   configuration buildSessionFactory serviceRegistry       return sessionFactory         UPDATE    In Hibernate 4 3 ServiceRegistryBuilder is deprecated  Use the following instead   serviceRegistry   new StandardServiceRegistryBuilder   applySettings              configuration getProperties    build

Yes  it is deprecated   http   docs jboss org hibernate core 4 0 javadocs org hibernate cfg Configuration html buildSessionFactory   specifically tells you to use the other method you found instead  buildSessionFactory ServiceRegistry serviceRegistry   - so use it   The documentation is copied over from release to release  and likely just hasn t been updated yet  they don t rewrite the manual with every release  - so trust the Javadocs   The specifics of this change can be viewed at    Source code  https   github com hibernate hibernate-core commit 0b10334e403cf2b11ee60725cc5619eaafecc00b Ticket  https   hibernate onjira com browse HHH-5991   Some additional references    http   relation to Bloggers HibernateCore40IsFinal http   relation to 19942 lace http   docs jboss org hibernate core 4 0 devguide en-US html ch07 html services-registry http   sourceforge net apps mediawiki hibernate index php title Category Services

A better way to create SessionFactory object in Latest hibernate release 4 3 0 onward is as follow   Configuration configuration   new Configuration   configure    StandardServiceRegistryBuilder builder   new StandardServiceRegistryBuilder    applySettings configuration getProperties     SessionFactory factory   configuration buildSessionFactory builder build

TL DR  Yes  it is  There are better ways to bootstrap Hibernate  like the following ones   Hibernate-native bootstrap  The legacy Configuration object is less powerful than using the BootstrapServiceRegistryBuilder  introduced since Hibernate 4   final BootstrapServiceRegistryBuilder bsrb   new BootstrapServiceRegistryBuilder        enableAutoClose     Integrator integrator   integrator    if  integrator    null        bsrb applyIntegrator  integrator       final BootstrapServiceRegistry bsr   bsrb build     final StandardServiceRegistry serviceRegistry        new StandardServiceRegistryBuilder bsr           applySettings properties             build     final MetadataSources metadataSources   new MetadataSources serviceRegistry    for  Class annotatedClass   entities          metadataSources addAnnotatedClass annotatedClass      String   packages   packages    if  packages    null        for  String annotatedPackage   packages            metadataSources addPackage annotatedPackage            String   resources   resources    if  resources    null        for  String resource   resources            metadataSources addResource resource            final MetadataBuilder metadataBuilder   metadataSources getMetadataBuilder        enableNewIdentifierGeneratorSupport true       applyImplicitNamingStrategy ImplicitNamingStrategyLegacyJpaImpl INSTANCE    final List lt Type gt  additionalTypes   additionalTypes    if  additionalTypes    null        additionalTypes stream   forEach type - gt            metadataBuilder applyTypes  typeContributions  sr  - gt                if type instanceof BasicType                    typeContributions contributeType  BasicType  type                 else if  type instanceof UserType                    typeContributions contributeType  UserType  type                 else if  type instanceof CompositeUserType                    typeContributions contributeType  CompositeUserType  type                                        additionalMetadata metadataBuilder    MetadataImplementor metadata    MetadataImplementor  metadataBuilder build     final SessionFactoryBuilder sfb   metadata getSessionFactoryBuilder    Interceptor interceptor   interceptor    if interceptor    null        sfb applyInterceptor interceptor      SessionFactory sessionFactory   sfb build      JPA bootstrap  You can also bootstrap Hibernate using JPA   PersistenceUnitInfo persistenceUnitInfo   persistenceUnitInfo getClass   getSimpleName     Map configuration   properties     Interceptor interceptor   interceptor    if  interceptor    null        configuration put AvailableSettings INTERCEPTOR  interceptor      Integrator integrator   integrator    if  integrator    null        configuration put           hibernate integrator provider             IntegratorProvider     - gt  Collections singletonList integrator       EntityManagerFactoryBuilderImpl entityManagerFactoryBuilder        new EntityManagerFactoryBuilderImpl          new PersistenceUnitInfoDescriptor persistenceUnitInfo            configuration    EntityManagerFactory entityManagerFactory   entityManagerFactoryBuilder build      This way  you are building the EntityManagerFactory instead of a SessionFactory  However  the SessionFactory extends the EntityManagerFactory  so the actual object that s built is aSessionFactoryImpl  too   Conclusion  These two bootstrapping methods affect Hibernate behavior  When using the native bootstrap  Hibernate behaves in the legacy mode  which predates JPA   When bootstrapping using JPA  Hibernate will behave according to the JPA specification   There are several differences between these two modes    How the AUTO flush mode works in regards to native SQL queries How the entity Proxy is built  Traditionally  Hibernate did not hit the DB when building a Proxy  but JPA requires throwing an EntityNotFoundException  therefore demanding a DB check  whether you can delete a non-managed entity      For more details about these differences  check out the JpaCompliance class

It s as simple as this  the JBoss docs are not 100  perfectly well-maintained  Go with what the JavaDoc says  buildSessionFactory ServiceRegistry serviceRegistry

It is not unusual to find discrepancies between different versions of documentation   Most developers view documentation as a chore  and they tend to put it off   As a rule of thumb  if the javadoc says one thing and some non-javadoc documentation contradicts it  the chances are that the javadoc is more accurate   Programmers are more likely to keep the javadoc up to date with changes to the code     because the  source  for the javadoc is in the same file as the code   In the case of  deprecated tags  it is a virtual certainty that the javadoc is more accurate   Developers deprecate things after careful consideration     and  generally speaking  they don t undeprecate them
