java - hibernate HQL元素错误

Question

我的 HibernateUserImpl 映射如下所示

<set name="groups" table="OS_USER_GROUP" inverse="false" cascade="none" lazy="false">
    <key column="user_id"/>
    <many-to-many column="group_id" class="com.opensymphony.user.provider.hibernate3.ahxu.impl.HibernateGroupImpl"/>
</set>

我像这样进行 HQL 查询

select distinct hibuser from HibernateUserImpl hibuser, hibuser.groups.elements  hibgroup where hibuser.name = ? and hibgroup.name = ?

我收到 hibuser.groups.elements 错误。有什么我错过的吗？

控制台出错

org.hibernate.hql.ast.QuerySyntaxException: hibuser.groups.elements is not mappe
d [select distinct hibuser from com.opensymphony.user.provider.hibernate3.ahxu.i
mpl.HibernateUserImpl hibuser, hibuser.groups.elements  hibgroup where hibuser.n
ame = ? and hibgroup.name = ?]

Answer 1

我认为您需要进行明确的加入。

    select distinct hibuser 
    from HibernateUserImpl hibuser
    join hibuser.groups hibgroup 
    where hibuser.name = ? and hibgroup.name = ?
