为什么加上ServiceRegistry不能操作mysql了
public void testMysql() {
Configuration config = new Configuration().configure();
//ServiceRegistry serviceRegistry = new StandardServiceRegistryBuilder().applySettings(config.getProperties()).build();
SessionFactory sessionFactory = config.buildSessionFactory();
Session session =sessionFactory.getCurrentSession();
Transaction transaction = session.beginTransaction();
Users u = new Users("啊啊啊","123456",3);
session.save(u);
transaction.commit();
sessionFactory.close();
}注释掉就可以增删改查了 添加ServiceRegistry之后mysql就没反应了呢 why？
