我是.NET中的新成员。我之前在Java中使用过Spring Framework和Hibernate，但这是我第一次使用.NET。为了开发我的应用程序，我使用Spring.Northwind解决方案作为示例。Spring.NET - 未将对象引用设置为对象的实例
Hibernate映射是：
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2">
<class name="EMSApplication.Domain.Employee, EMSApplication.Domain" table="ems_Employees" proxy="EMSApplication.Domain.IEmployee, EMSApplication.Domain" lazy="true">
<id name="Id" type="System.Int32">
<column name="Id" not-null="true"/>
<generator class="native"/>
</id>
<property name="Username" type="System.String">
<column name="Username" not-null="true"/>
</property>
<property name="Firstname" type="System.String">
<column name="Firstname" not-null="true"/>
</property>
</class>
</hibernate-mapping>
正如你可以看到Employee类只有三个领域。它实现了IEmployee，它包含这些字段的get和set方法的定义（如果你想看看我可以提供的这些类）。
现在的Web.config我有我已设置弹簧作为sectionGroup和它定义为：
<configSections>
<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>
<spring>
<parsers/>
<context>
<resource uri="~/Web.xml"/>
</context>
</spring>
<databaseSettings>
<add key="db.datasource" value="Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\JYM.mdf;Integrated Security=True;User Instance=True"/>
</databaseSettings>
我也有添加Spring.Data.NHibernate.Support.OpenSessionInViewModule.SessionFactoryObjectName中的AppSettings键：
<appSettings>
<add key="Spring.Data.NHibernate.Support.OpenSessionInViewModule.SessionFactoryObjectName" value="NHibernateSessionFactory"/>
</appSettings>
系统的的HttpModules .web有以下条目：
<httpModules>
<add name="Spring" type="Spring.Context.Support.WebSupportModule, Spring.Web"/>
<add name="OpenSessionInView" type="Spring.Data.NHibernate.Support.OpenSessionInViewModule, Spring.Data.NHibernate32"/>
</httpModules>
最后是春天资源web.xml中有以下对象：
<object type="Spring.Objects.Factory.Config.PropertyPlaceholderConfigurer, Spring.Core">
<property name="ConfigSections" value="databaseSettings"/>
</object>
<db:provider id="DbProvider" provider="System.Data.SqlClient" connectionString="Data Source=|DataDirectory|\JYM.mdf"/>
<object id="NHibernateSessionFactory" type="Spring.Data.NHibernate.LocalSessionFactoryObject, Spring.Data.NHibernate32">
<property name="DbProvider" ref="DbProvider"/>
<property name="MappingResources">
<list>
<value>assembly://EMSApplication/Domain/EMSApplication.hbm.xml</value>
</list>
</property>
<property name="HibernateProperties">
<dictionary>
<entry key="hibernate.connection.provider" value="NHibernate.Connection.DriverConnectionProvider"/>
<entry key="dialect" value="NHibernate.Dialect.MsSql2008Dialect"/>
<entry key="connection.driver_class" value="NHibernate.Driver.SqlClientDriver"/>
<entry key="proxyfactory.factory_class" value="NHibernate.Bytecode.DefaultProxyFactoryFactory, NHibernate"/>
<entry key="show_sql" value="true"/>
<entry key="hbm2ddl.auto" value="update"/>
<entry key="cache.use_query_cache" value="true"/>
</dictionary>
</property>
<property name="ExposeTransactionAwareSessionFactory" value="true" />
</object>
<object id="transactionManager" type="Spring.Data.NHibernate.HibernateTransactionManager, Spring.Data.NHibernate32">
<property name="DbProvider" ref="DbProvider"/>
<property name="SessionFactory" ref="NHibernateSessionFactory"/>
</object>
<object type="Spring.Dao.Attributes.PersistenceExceptionTranslationPostProcessor, Spring.Data"/>
<object id="EmployeeDao" type="EMSApplication.NHibernate.HibernateEmployeeDao">
<property name="SessionFactory" ref="NHibernateSessionFactory"/>
</object>
<tx:attribute-driven transaction-manager="transactionManager"/>
现在，当我从Visual Studio 2010年开始调试我得到
System.NullReferenceException：对象不设置到对象的实例 。
完整的堆栈跟踪是：

在这里，你可以看到：
[ObjectCreationException：与名 错误创建对象NHibernateSessionFactory'在“文件 定义[d ：\ Code \ EMSApplication \ EMSApplication \ Web.xml] line 14'： 对象初始化失败：无法从 输入流配置数据存储]
所以我无法计算如何解决这个问题。任何帮助或建议，我真的很感激。
谢谢。
注：我没有在IIS中更改任何设置7.
