Spring.net中的CannotLoadObjectTypeException [英] CannotLoadObjectTypeException in Spring.net

问题描述

我在vs 2010中的asp.net 3.5项目中使用spring.net 1.3.1.我需要Spring来创建和操作对象.

I'm using spring.net 1.3.1 in a asp.net 3.5 project in vs 2010. I'm not doing any kind of mvc stuff; I needed Spring to create and manipulate objects.

我已按照文档进行操作，添加了Spring.Core和Spring.Web dll参考，我的web.config如下所示:

I've followed the documentation, added Spring.Core and Spring.Web dlls reference my web.config is like this:

   <sectionGroup name="spring">
    <section name="context" type="Spring.Context.Support.WebContextHandler, Spring.Web"/>
    <section name="objects" type="Spring.Context.Support.DefaultSectionHandler, Spring.Core"/>

  </sectionGroup> 
   <system.web>
     <httpModules>
        <add name="Spring" type="Spring.Context.Support.WebSupportModule, Spring.Web"/>
     </httpModules>
     <!-- no spring confi in httpHandlers-->
  </system.web>
   <spring>
    <context>
      <resource uri="~/config/clients.xml" />
    </context>
  </spring>

在clients.xml中

in clients.xml

<?xml version="1.0" encoding="utf-8" ?>
<objects xmlns="http://www.springframework.net"> 
  <object id="CAL"  type="myrouter.clientcode.CAL, myrouter.clientcode"/>  
</objects>

在Defaults.aspx.cs中

in Defaults.aspx.cs

  IApplicationContext ctx = ContextRegistry.GetContext();
  CAL calobject = (CAL)ctx.GetObject("CAL");

我要

很抱歉，此篇长文章；我想尽可能地精确，并提供尽可能多的信息.我想我缺少了一些东西，但无法弄清楚是什么.在asp.net的spring.net配置中， HttpHandler 是必须的吗?

Sorry for this long post; I wanted to be as precised as possible and give as much as information that I could. I think I'm missing something but just can't figure out what. Is the HttpHandler a must in spring.net configuration in asp.net?

推荐答案

通常，此问题是您的某些错误导致的

Usually this issue is the result of some error in your

<object id="CAL"  type="myrouter.clientcode.CAL, myrouter.clientcode"/>  

配置.

检查/验证以下内容:

• 名称空间 myrouter.clientcode 确实是 CAL 类所在的地方
• 包含这种类型的程序集实际上是 myrouter.clientcode
• 这些名称空间和程序集名称在re:区分大小写方面也匹配
