如何使用Criteria在Hibernate中对连接表中的属性进行查询

Question

我有以下映射：

<hibernate-mapping package="server.modules.stats.data">
    <class name="User" table="user">
       <id name="id">
            <generator class="native"></generator>
       </id>
       <many-to-one name="address" column="addressId" unique="true" lazy="false" />
    </class>
    <class name="Address" table="address">
       <id name="id">
            <generator class="native"></generator>
       </id>
       <property name="street" />
    </class>
</hibernate-mapping>

如何选择Criteria查询以选择居住在某条街道上的所有用户？

这是为此SQL创建Criteria查询：

Select * from user join address on user.addressId = address.id where address.street='someStreet'

Answer 1

String theStreet = "the_street_name";

DetachedCriteria dc = DetachedCriteria.forClass(User.class);
dc.createAlias("address", "addrAlias");
dc.add(Restrictions.eq("addrAlias.street", theStreet));
List<User> users = getHibernateTemplate().findByCriteria(dc);
