在ICollection的属性上拦截NHibernate持久性操作（许多关联）

好吧，我采用了实现NHibernate侦听器的解决方案，所以我有一个像这样的侦听器：

public class CustomSaveUpdateEventListener : IPostInsertEventListener, IPostUpdateEventListener {    private void ScheduleToCommit(AbstractPostDatabaseOperationEvent @event) {        // Some filter        if (@event.Entity.GetType().FullName.Equals(MY_ENTITY_TO_INTERCEPTS) { object o = @event.Entity; // Some logic... // ... // ... IQuery namedQuery = @event.Session.GetNamedSQLQuery(MY_NAMED_QUERY); //namedQuery.SetParameter(...); // <== You can set parameters //namedQuery.ExecuteUpdate(); // <== DO NOT EXCEUTE HERE, this launches more events recursively and can generate stackoverflow @event.Session.ActionQueue.RegisterProcess(new MyActionBeforeCommit(@event, namedQuery).SavevaluesOperation); }        }    }    public void onPostInsert(PostInsertEvent @event) {        ScheduleToCommit(@event);    }    public void onPostUpdate(PostUpdateEvent @event) {        ScheduleToCommit(@event);    }}

而且我的对象

MyActionBeforeCommit()

public class MyActionBeforeCommit {    private AbstractPostDatabaseOperationEvent e;    private IQuery query;    public MyActionBeforeCommit(AbstractPostDatabaseOperationEvent e, IQuery query) {        this.e = e;        this.query = query;    }    public void SavevaluesOperation() {        // Here your query will be executed only when a transation is commited, if         // it's rolledback this won't be executed        query.ExecuteUpdate();     }}

最后，我们需要在NHibernate配置上注册新的侦听器，如下所示：

Configuration.SetListener(ListenerType.PostInsert, new    CustomSaveUpdateEventListener());Configuration.SetListener(ListenerType.PostUpdate, new CustomSaveUpdateEventListener());

而且效果很好。这是一个非常好的NHibernate功能，非常强大。
