hibernate batch insert

public void importBatch(Collection objs) {       
       
       session = this.sessionFactory.openSession();
       session.setCacheMode(CacheMode.IGNORE);
       session.getTransaction().begin();
              
       for(Object o : objs) {           
           session.save(o);
           if(++saveCount % objs.size() == 0)
            {                       
               session.getTransaction().commit();
               session.clear();
               saveCount = 0;
            }
       }       
       
       session.close();
    }
           

The code above is most certainly not threadsafe. SessionFactory can safely be used as an instance variable, but not the Session. The scope "prototype" means a new instance is created, but per injection, not per request.

Session session = HibernateUtil.getSessionFactory().getCurrentSession(); 
        Transaction tran = session.beginTransaction(); 
        session.setCacheMode(CacheMode.IGNORE); 

        PreparedStatement stmt; 
        try { 
            stmt = session.connection().prepareStatement("INSERT INTO EVENTS(EVENT_DATE, title) VALUES(?,?)");
             for (int i = 0; i < 200000; i++) { 
                stmt.setTimestamp(1, new Timestamp(new Date().getTime())); 
                stmt.setString(2, "Title["+i+"]"); 
                stmt.addBatch(); 
            } 
            stmt.executeBatch(); 
        } catch (SQLException e) { 
            e.printStackTrace();  //To change body of catch statement use File | Settings | File Templates.
             tran.rollback(); 
        } 
        tran.commit(); 
        session.close(); 
        HibernateUtil.getSessionFactory().close();
