从测试网站调用 WCF 服务方法会引发错误

Question

我在 Fluent NHibernate 中实现了 WCF 服务库并托管在 Windows 服务下。
另外，我有一个正在添加服务引用的网站。

现在，当我从 WebSite 调用 WCF 服务方法时，我收到以下错误：

[FaultException`1: An invalid or incomplete configuration was used while creating a SessionFactory. Check PotentialReasons collection, and InnerException for more detail.

* Database was not configured through Database method.
]
  System.Runtime.Remoting.Proxies.RealProxy.HandleReturnMessage(IMessage reqMsg, IMessage retMsg) +7596735
  System.Runtime.Remoting.Proxies.RealProxy.PrivateInvoke(MessageData& msgData, Int32 type) +275
  TeamworksReportService.ITemplateService.ListTemplatesByTemplateType(Int32 userId, TemplateType templateType) +0
  TeamworksReportService.TemplateServiceClient.ListTemplatesByTemplateType(Int32 userId, TemplateType templateType)

有什么想法吗？

WCF 服务中的 App.Config：

Answer 1

这与 WCF 无关 - 这是一个 NHibernate 问题。看起来您可能已尝试在 Web.config 文件中配置 DB 连接字符串，而不是 Windows 服务的 App.config，这是它需要的位置？

如果您使用 NHibernate XML 配置文件进行配置，该配置文件是使用 Windows 服务而不是 Web 应用程序部署的吗？您尝试运行的版本是否可以访问代码中 XML 文件的（硬编码！）路径？运行服务的帐户是否具有（硬编码！）路径的权限？

最好的办法是确保 hibernate.cfg.xml 始终与您的二进制文件一起位于同一文件夹中，并从对 Configure 的调用中删除路径参数。

好像你使用 SQL Server 来托管你的会话，而你还没有为你的 wcf 服务中的会话状态配置 sql server。
