如何在nHiberate中创建一个只读会话? [英] how to create a readonly session in nHiberate?

问题描述

是否可以在nHibernate中创建只读连接?

Is it possible to creat a readonly connection in nHibernate ?

只读:nHibernate不会隐式或显式刷新对基础数据库的任何更改.

Read-only : where nHibernate will not flush out any changes to the underlying database implicitly or explicitly.

关闭nhibernate连接时，它会自动清除对持久对象的更改.

When closing a nhibernate connection it does automatically flush out the changes to the persistent object.

将刷新模式设置为从不"是一种方法-但这是可逆的(即某些代码可以重置刷新模式).

Setting the flush mode to never is one way - but is reversable (i.e some code can reset the flush mode).

推荐答案

我认为您已经找到了解决方案，将刷新模式设置为从不.是的，它是可变的，但是即使不是，代码也可以简单地创建另一个具有不同刷新模式的会话.

I think you've already found the solution, setting flush mode to never. Yes, it is changeable but even if it wasn't, code could simply create another session that had a different flush mode.

我认为适当的解决方案是使用与只有SELECT权限(或任何其他权限)的数据库的连接，对>建议为只读，并强制执行适合您的情况).允许使用类似ReadOnlySessionFactory.Create()的东西来维护单独的ISessionFactory工厂.

I think the appropriate solution is to suggest read-only with session.FlushMode = FlushMode.Never and enforce it by using a connection to the database that only has SELECT permissions (or whatever is appropriate for your situation). Maintaining separate ISessionFactory factories might help by allowing something like ReadOnlySessionFactory.Create().
