No CurrentSessionContext configured, while using getCurrentSession()

Question

I am changing my code from openSession() to getCurrentSession() so it won't create connections at each request. I have done code in class as:

    public Session openSession(boolean current1){
        int count = 0;
        int MAX_COUNT = 10;
//      this.printIdMap();
        while( count++ < MAX_COUNT) {
            try {
                this.session = this.getSessionFactory().getCurrentSession();
                this.transaction = this.session.beginTransaction();
                
                this.IncDecCounter(true);
//              this.session.getTransaction().commit();
                break;
            }
            catch ( Exception e ) {
                this.printIdMap();
                e.printStackTrace();
                try { this.session.close(); } catch( Exception e1 ) {}
            }
        }
        return this.session;
    }

I have checked in multiple places to set property in hibernate.cfg.xml file.

<property name="hibernate.current_session_context_class">thread</property>

I also tried

<property name="hibernate.current_session_context_class">org.hibernate.context.internal.ThreadLocal‌​SessionContext</property>

but facing error as

org.hibernate.HibernateException: No CurrentSessionContext configured!

The hibernate version which I am using is 5.4.1

Lets imagine your Hibernate session manager class looks like this

public class HibernateSessionManager {

    private static final SessionFactory sessionFactory = buildSessionFactory();

    private static SessionFactory buildSessionFactory() {

        Configuration configuration = new Configuration();
        configuration.configure("hibernate.cfg.xml");

        ServiceRegistryBuilder serviceRegistryBuilder = new ServiceRegistryBuilder()
                .applySettings(configuration.getProperties());
        return configuration.buildSessionFactory(serviceRegistryBuilder
                .buildServiceRegistry());
    }

    public static SessionFactory getSessionFactory() {
        return sessionFactory;
    }

}

Use this property in your configuration file

<property name="hibernate.current_session_context_class">thread</property>

Instead of you currecnt one i.e

<property name="hibernate.current_session_context_class">org.hibernate.context.internal.ThreadLocal??SessionContext</property>

And get your session with

Session session = HibernateSessionManager.getSessionFactory().openSession();
