public class T {

}

public static void test(){

SessionFactory sf = new Configuration().configure().buildSessionFactory();

System.out.println(session);
        session.beginTransaction();

        Books book = new Books();
        book.setName("aa");
        book.setPirce(23);
        book.setPublishTime(new Date());
        session.save(book);

        session.getTransaction().commit();
