Hibernate CRUD with MySQL Database – Java

To Update Record Using Hibernate Session:

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

StandardServiceRegistryBuilder ssrb = new StandardServiceRegistryBuilder().applySettings(cfg.getProperties()); 

SessionFactory factory = cfg.buildSessionFactory(ssrb.build()); Session session = factory.openSession(); 

Transaction t = session.beginTransaction(); 

Users u = (Users) session.load(Users.class, 6); // load record having id 6 into u object

u.setLastName("Nitnavre"); // set column value which needs to update

System.out.println(session.save(u)); // fire update query using save function of hibernate

t.commit(); // commit the update changes to save state in database

System.out.println("Record updated successfully...");
