Public class HBUtilty { private static ThreadLocal < session > threadLocal = new ThreadLocal < session > (); private static SessionFactory factory = null; static { factory = Configuration.configure(“com / esc / conf / hibernate.cfg.xml”).buildSessionFactory(); } public static Session getSession() { Session session = null; if (threadLocal.get() == null) { session = factory.openSession() threadLocal.set(session); } else { session = threadLocal.get() } return session; } public static void closeSession() { Session session = null; if (threadLocal.get() != null) { session = threadLocal.get(); session.close(); threadLocal.remove(); } } public void closeSessionFactory() { factory.close(); } }
