Answer 1

org.hibernate.hql.ast.QuerySyntaxException: unexpected token: null near line 1, column 62 [from com.baidu.manageSystem.machineRoom.dto.Funct where code=]是不是code没有初期化？

Answer 2

检查你的HQL 语句 HQL语句错了 
HQL查询的不是数据库里的表 而是实体类的名字  注意区分大小写

Answer 3

org.hibernate.hql.ast.QuerySyntaxException: unexpected token: null near line 1, column 62 [from com.baidu.manageSystem.machineRoom.dto.Funct where code=]没有找到这个类。。
