String.Net “System.TypeInitializationException”类型的未经处理的异常在 Spring.NetDemo.exe 中发生

今天编写String.Net时,遇到“System.TypeInitializationException”类型的未经处理的异常在 Spring.NetDemo.exe 中发生

原因配置文件的顺序写错

原顺序:

 <configuration>

   <startup>

     <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />

   </startup>

   <configSections>

     <sectionGroup name="spring">

       <section name="context" type="Spring.Context.Support.ContextHandler,Spring.Core"/>

       <section name="objects" type="Spring.Context.Support.DefaultSectionHandler,Spring.Core"/>

     </sectionGroup>

   </configSections>

   <spring>

     <!--Spring.Net对象容器的配置-->

     <context>

       <!--容器里所有对象在哪里配置?-->

       <resource uri="config://spring/objects"/>

     </context>

     <!--objects:配置的容器的里面的对象-->

     <objects xmlns="http://www.springframework.net" >

       <description>An example that demonstrates simple IoC features.</description>

       <object name="UserInfoDal"  type="Spring.NetDemo.UserInfoDal, Spring.NetDemo" singleton="false" >

       </object>

     </objects>

   </spring>

 </configuration>

改正后的顺序为:

  <configSections>

     <sectionGroup name="spring">

       <section name="context" type="Spring.Context.Support.ContextHandler,Spring.Core"/>

       <section name="objects" type="Spring.Context.Support.DefaultSectionHandler,Spring.Core"/>

     </sectionGroup>

   </configSections>

   <spring>

     <!--Spring.Net对象容器的配置-->

     <context>

       <!--容器里所有对象在哪里配置?-->

       <resource uri="config://spring/objects"/>

     </context>

     <!--objects:配置的容器的里面的对象-->

     <objects xmlns="http://www.springframework.net" >

       <description>An example that demonstrates simple IoC features.</description>

       <object name="UserInfoDal"  type="Spring.NetDemo.UserInfoDal, Spring.NetDemo" singleton="false" >

       </object>

     </objects>

   </spring>

   <startup>

     <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />

   </startup>
