Java hibernate HQL元素错误

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>

我得到了hibuser.groups.elements的错误。有什么我错过的吗

控制台中的错误

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 = ?]

---

我认为你需要明确加入

hibuser.groups是一个集合，因此您无法访问集合元素的属性

这可以如下所示：

列表组=。。。； 组、元素

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 = ?]

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

select element 
from HibernateUserImpl hibuser 
join hibuser.groups group 
join group.elements element 
where hibuser.name = ? and hibgroup.name = ? and element.whatever = something
