我面临着以下行为：
org.hibernate.hql.ast.QuerySyntaxException: user is not mapped [select s.SubscriptionsId,s.SubscriptionName, s.ChamberOfCommerce, s.AccountingFirmId,(select SubscriptionName from subscriptions where SubscriptionsId=s.AccountingFirmId) as AFName,(select ChamberOfCommerce from subscriptions where SubscriptionsId=s.AccountingFirmId) as AFChamberOfCommerce,(select FtpFolder from subscriptions where SubscriptionsId=s.AccountingFirmId) as FtpFolder from user u,subscriptions s, usersubscriptions us where u.openID=:openId and u.UserId=us.UserId and us.SubscriptionsId = s.SubscriptionsId]
我的代码如下：
Query query = this.getSession().createQuery(
this.getQuery("com.yob.sbs.dpc.getSubsctionByOpenId"))
.setParameter("openId", openId);
我正在使用密钥com.yob.sbs.dpc.getSubsctionByOpenId的hibernate查询。我的查询如下：
com.yob.sbs.dpc.getSubsctionByOpenId =
select
s.SubscriptionsId,
s.SubscriptionName,
s.ChamberOfCommerce,
s.AccountingFirmId,
(select SubscriptionName from subscriptions where
SubscriptionsId = s.AccountingFirmId) as AFName,
(select ChamberOfCommerce from subscriptions where
SubscriptionsId = s.AccountingFirmId) as AFChamberOfCommerce,
(select FtpFolder from subscriptions where
SubscriptionsId = s.AccountingFirmId) as FtpFolder
from user u, subscriptions s, usersubscriptions us
where
u.openID = :openId and
u.UserId = us.UserId and
us.SubscriptionsId = s.SubscriptionsId
和用户数据对象如下：

但是在执行程序后，我得到了上述异常。
我的代码有什么问题？提前谢谢。
答案 0 :(得分：2)
问题很可能是from条款。您应该将实体名称大写，并且实体名称和属性在JPQL中区分大小写：
....
from User u, Subscriptions s, UserSubscriptions us
where
....
此外，您可能会遇到属性名称问题。在您的查询中，所有这些都是大写的：
where
u.openID = :openId and
u.UserId = us.UserId and
但是，JPA提供商很可能会期望userId，而不是UserId。
答案 1 :(得分：-1)
在hibernate.cfg.xml中添加用户表映射，如下所示：
<hibernate-mapping>................
<mapping class="com.model.User"></mapping>
