查了一下Dao层方法，里面的hql写成了sql语句，从而导致这样的报错。
总结一下原因：
hibernate框架在映射数据库表时，是将表转换为实体类，用操作数据对象代替操作表，这跟java语言面向对面象的操作原来一样，hql提供更加丰富灵活、更为强大的查询能力，hql语句对应实体类和实体类的属性进行了封装，查询语句from后面接的不是表名称，而是javabean实体对象名，where条件后面的不是表字段，而是javabean实体属性名。
扩展提示，网上其他答案：在hibernate里面写sql执行时候要用了session.createQuery(sql); 需要用session.createSQLQuerysql);
