在流利的弹簧中我可以设置 Fetch 。 有些东西还是没有。 Lazy Load to a reference 或 HasMany。 如果我同时使用, 会发生什么?
这两种方法如何反映以这三种方式查询数据?
class UserMap
{
HasMany(x=>x.Contacts). (Fetch or Not.LazyLoad)
References(x=>x.Supervisor). (Fetch or Not.LazyLoad)
}
session.Query<User>();
session.Query<User>().FetchMany(x=>x.Contacts);
session.Get<User>(ID);
问题是查询/ HQL 不考虑 < code> Fetch 。 所以, 在运行查询后, 它会立即尝试将您的 < code> 不。 Lazy Looad 属性 < strong > 以 < / strong > 方式获取 。
