c# - CaSTLe Windsor Nhibernate Facility 延迟加载

Question

我正在迁移我的 mvc web 应用程序以使用 Nhibernate Facility 来管理休眠 session 。

我遇到了这个奇怪的问题；

当我通过以下方式在 web.config/httpmodules 下注册 SessionWebModule 时:

<add name="NHibernateSessionWebModule"
type="Castle.Facilities.NHibernateIntegration.Components.Web.SessionWebModule,
Castle.Facilities.NHibernateIntegration" />

系统无法延迟加载对象。我没有得到任何 session 异常。

如果我不将它添加到 web.config 中，延迟加载工作正常。就注册温莎而言，这一切似乎都还可以容器并注册 Nhibernate Facility。 hibernate 设施能够提供 session 管理器和 Windsor 容器能够解析对象。

当然，如果没有 SessionWebModule，Nhibernate Facility 几乎毫无用处对我来说，在这种情况下，它无法妥善管理 session 。我看到 datareader 是 allready open type exceptions 这是不好..

我被困住了，需要紧急解决这个问题我会的感谢您的任何帮助。

我在下面包括了我的配置和代码的一些部分提供更多信息

            <facility id="nhibernatefacility" isWeb="false"

Answer 1

这是设计使然。您必须保持 session 打开。

如果你做的是web，我建议你在请求开始时打开session，在请求结束时关闭。
