  //SessionFactory 创建session的工厂
  public void fun1(){
    //1加载配置
    Configuration  conf = new Configuration().configure();
    //2 根据Configuration 配置信息创建 SessionFactory
    SessionFactory sf = conf.buildSessionFactory();
    //3 获得session
    //3.1 openSession => 获得一个全新的Session对象
    sf.openSession();
    //3.2 getCurrentSession => 获得与当前线程绑定的session对象
    // 调用getCurrentSession 需要加上一个配置: <property name="hibernate.current_session_context_class">thread</property>
    sf.getCurrentSession();
