问题
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.
i've followed the documentation, added Spring.Core and Spring.Web dlls referece 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>
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>
in Defaults.aspx.cs
IApplicationContext ctx = ContextRegistry.GetContext();
CAL calobject = (CAL)ctx.GetObject("CAL");
i'm getting
[TypeLoadException: Could not load type from string value 'myrouter.clientcode.CAL, myrouter.clientcode'.] Spring.Core.TypeResolution.TypeResolver.Resolve(String typeName) in

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?
thanks for reading
回答1:
Usually this issue is the result of some error in your
<object id="CAL" type="myrouter.clientcode.CAL, myrouter.clientcode"/>
configuration.
Check/verify the following:
- the namespace myrouter.clientcode is really where the CAL class exists
- the assembly that contains this type is really myrouter.clientcode
- these namespaces and assembly names match in re: case-sensitivity as well
回答2:
Never mind, i got it fixed.i used the wrong assembly info.
