Question

我有一点问题，当我插入一个新值时，程序不起作用，它不会在sql中重新创建表，请检查代码，如果有任何错误请告诉我，我正在使用{{ 1}}

1）主要课程

Hibernate 5

2）

    package yashwanth;
    import org.hibernate.Session;
    import org.hibernate.SessionFactory;
    import org.hibernate.cfg.Configuration;

    public class HibernateTest {

     public static void main(String[] args) {
        // TODO Auto-generated method stub
     UserDetails user=new UserDetails();
    user.setUserId(2);
user.setUserName("Second User");
SessionFactory SessionFactory=new     Configuration().configure().buildSessionFactory();
Session session=SessionFactory.openSession();
    session.beginTransaction();
    session.save(user);
    session.getTransaction().commit();
    }
}
