2、错误原因

     这里调用方法this.getCurrentSession().createQuery(sql.toString()).list(),是利用Hibernate HQL查询,而不是SQL查询;方法是HQL查询,但是SQL语句却是SQL查询方法语句,这样方法和参数不一致导致出错

		StringBuilder sql = new StringBuilder();
		sql.append("select * from t_student_info ");
		list = this.getCurrentSession().createQuery(sql.toString()).list();
		
		return list;
	}

}

3、解决办法

(1)修改sql语句

(2)调用Hibernate SQL查询方法
