Hibernate课程 初探一对多映射4-3 测试--信息查询

    //查询学生所在班级
    public static  void showGidByStudent(){
        Session sess1 = HibernateUtil.getSession();
        Student stu1 = (Student) sess1.get(Student.class, 1);
        System.out.println("学生姓名为："+stu1.getSname());
        Grade grad1 = stu1.getGrade();
        System.out.println("该学生班级为："+grad1.getGid());
        HibernateUtil.closeSession(sess1);
    }
