如何在没有第三方插件的Hibernate Projections中设置输出对象的嵌套属性

Question

我有以下实体 -

UserDB{
String name;
Address address;
//getter Setter of name & address
}

User{
String name;
Address address;
//getter Setter of name & address
}

Address{
String line1;
String line2;
String postalCode;
//getter setter of line1,line2,postalCode
}

我们可以在hibernate Projections中设置嵌套属性，如下所示吗？不使用第三方插件

public User getUserInfo(Long id) {
Criteria criteria = getCriteria(UserDB.class);
criteria.createAlias("addressDB", "addDbAlias", JoinType.INNER_JOIN);
    criteria.setProjection(Projections.projectionList()
                .add(Projections.property("name").as("name"))

        .add(Projections.property("addDbAlias.line1").as("address.line1")) //is this ".as(address.line1)" correct way? If not how to achieve this

            .add(Projections.property("addDbAlias.line2").as("address.line2"))
                .add(Projections.property("addDbAlias.postalCode").as("address.postalCode")));
criteria.add(Restrictions.eq("id", id));

上面的代码给出错误：引起：org.hibernate.PropertyNotFoundException：找不到用户上的address.line1的setter

如何解决此错误..在此先感谢!!
