IIS Server and Spring.NET object instantiation fai

问题:

I am using Spring.NET in my web application. At the beginning the application was set to use Visual Studio Development Server. Everything was working fine. But when I changed it to use Local IIS Web server and created a Virtual Directory and run the application I got System.NullReferenceException. I think I need to configure my Web.config in such a way so the Spring.NET work with IIS. The Web.config file is:

<configuration>
<configSections>
    <sectionGroup name="common">
    <section name="logging" type="Common.Logging.ConfigurationSectionHandler, Common.Logging" />
    </sectionGroup>
    <sectionGroup name="spring">
    <section name="context" type="Spring.Context.Support.WebContextHandler, Spring.Web" />
    <section name="parsers" type="Spring.Context.Support.NamespaceParsersSectionHandler, Spring.Core" />
    </sectionGroup>
    <section name="databaseSettings" type="System.Configuration.NameValueSectionHandler" />
</configSections>
<common>
    <logging>
    <factoryAdapter type="Common.Logging.Log4Net.Log4NetLoggerFactoryAdapter, Common.Logging.Log4Net">
        <arg key="configType" value="FILE-WATCH" />
        <arg key="configFile" value="~/Config/Log4Net.xml" />
    </factoryAdapter>
    </logging>
</common>
<spring>
    <parsers />
    <context>
    <resource uri="~/Data.xml" />
    <resource uri="~/Web.xml" />
    </context>
</spring>

</databaseSettings>
<appSettings>
    <add key="Spring.Data.NHibernate.Support.OpenSessionInViewModule.SessionFactoryObjectName" value="NHibernateSessionFactory" />

</system.webServer>
<location path="Secured">   
    <system.webServer>
    <directoryBrowse enabled="false" />
    </system.webServer>
</location>
</configuration>

What else I have to add here. It was working fine previously but now it is giving me error. You help be appreciated.

Your web.config lacks parts of the required configuration, from the docs:

Configuration for IIS 7.0 on Windows Server 2008, Win7 and Windows Vista

There is some configuration that is specific to using IIS7, the appropriate code snippit to place in web.config shown below.

<system.webServer>
  <validation validateIntegratedModeConfiguration="false"/>
  <modules>
    <add name="Spring" type="Spring.Context.Support.WebSupportModule, Spring.Web"/>
  </modules>
  <handlers>
    <add name="SpringPageHandler" verb="*" path="*.aspx" type="Spring.Web.Support.PageHandlerFactory, Spring.Web"/>
    <add name="SpringWebServiceHandler" verb="*" path="*.asmx" type="Spring.Web.Services.WebServiceHandlerFactory, Spring.Web" />
    <add name="SpringContextMonitor" verb="*" path="ContextMonitor.ashx" type="Spring.Web.Support.ContextMonitor, Spring.Web"/>
  </handlers>
</system.webServer>
