NHibernate IStatelessSession 和多对多关系
我在两个实体之间存在多对多关系。作为批处理过程的一部分，我正在创建大量这些实体并将它们关联在一起。这是使用 IStatelessSession。
我正在使用 NHibernate 3.0。
实体：
class Entity1
{
ICollection<Entity2> Entities { get; set; }
}
class Entity2
{
ICollection<Entity1> Entities { get; set; }
}
基本上批处理代码看起来像这样：
var entity1 = new Entity1();
var entity2 = new Entity2();
entity1.Entities.Add(entity2);
entity2.Entities.Add(entity1);
Session.Insert(entity1); // IStatelessSession.Insert
Session.Insert(entity2);
两个实体被正确持久化，但是它们之间的关系表没有随着两个实体之间的关系而更新。
我知道这与无状态会话不跟踪对象这一事实有关。但我该如何实现多对多的持久性呢？
I have a many-to-many relationship between two entities. As part of a batch process, I am creating a large number of these entities and relating them together. This is using an IStatelessSession.
I am using NHibernate 3.0.
Entities:
class Entity1
{
ICollection<Entity2> Entities { get; set; }
}
class Entity2
{
ICollection<Entity1> Entities { get; set; }
}
Basically the batch code looks something like:
var entity1 = new Entity1();
var entity2 = new Entity2();
entity1.Entities.Add(entity2);
entity2.Entities.Add(entity1);
Session.Insert(entity1); // IStatelessSession.Insert
Session.Insert(entity2);
The two entities are correctly persisted, however the relationship table between them is not updated with the relationship between the two entities.
I understand that this has to do with the fact that stateless sessions don't track the objects. But how would I go about achieving many-to-many persistence?

无状态会话会忽略集合。您应该使用常规 ISession 并以合理的时间间隔（例如每 500 个对象）调用
ISession.Clear。这样，一级缓存就不会变得臃肿，并且您将获得不错的性能。Collections are ignored by stateless sessions. You should use regular ISession and call
ISession.Clearat a reasonable interval (say every 500 objects). This way 1st level cache will not get bloated and you will have decent performance.
