我在hql中使用'not equal'查询.

 @Override
    public Student findStudentsByYear(String year) {
        String queryString = "from Student where year<>:year ";
        Query query =   sessionFactory.getCurrentSession().createQuery(queryString);        
        query.setParameter("year", year);
        return (Student)query.uniqueResult();
    }

但它无法正常工作.如何正确编写此查询

我的学生表是
