NHibernate每个表的不同会话生存期

Question

I'm running a wpf app. With a nhibernate session you only have to query a table once and you can access it as many times as you like from cache.

But i like to cache some tables through the entire app because they almost never change, like users and usergroups. Should i use one session for the entire app or is there another solution?

Answer 1

The cache that NHibernate provides as part of the session is referred to as the first level cache.

For caching things longer than the duration of a session, you need to take a look at the second level cache . NHibernate ships with implementations for several cache providers (memcached, SysCache, etc.).

Answer 2

Here's an excellent article on how to configure the 2nd level cache using FluentNHibernate
