NHibernate Session.Flush&驱逐vs清除 [英] NHibernate Session.Flush & Evict vs Clear

问题描述

在测试中，我想保留一个对象，然后通过从数据库(而不是会话)中获取它来证明它是持久的，我发现以下内容之间没有区别:

In a test where I want to persist an object and then prove it was persisted by fetching it from the db (and not the session), I notice no difference between the following:

// save it
session.Clear()
// fetch it

或

// save it
session.Flush()
session.Evict(_instance)
// fetch it

我里面的懒惰程序员倾向于两行一行.我是否出于某些原因错过了更多支持这两行?

The lazy programmer in me leans towards one line over two. Is there some reason I am missing to favor the two lines more?

推荐答案

会话.实际上清除取消所有待处理的保存/更新/等.

session.Clear actually cancels all pending saves/updates/etc.

如果不这样做，那是因为您使用的是身份，因此该实体可以持久保存而不刷新.

If it doesn't, it's because you're using identity so the entity is persisted without flushing.
