Question

I am trying to create an ASP.NET MVC application, using Spring.NET to inject dependencies. The application has three tiers: Controller, Service, and Data.

I have defined the objects in the file “~\Resources\objects.xml”.

My first object, UserAccountController, requires the injecion of two Service-tier classes: UserAccountService and DepartmentService. So, the definition in objects.xml looks like this:

<object id="UserAccountController" type="App.Controllers.UserAccountController, App">
    <constructor-arg index="0" ref="DepartmentService" />
    <constructor-arg index="1" ref="UserAccountService" />
</object>

<object id="UserAccountService" type="App.Service.UserAccountService, App">
    <property name="UserAccountDao" ref="UserAccountDao" />
</object>

<object id="UserAccountDao" type="App.Data.UserAccountDao, App" />

<object id="DepartmentService" type="App.Service.DepartmentService, App">
    <property name="DepartmentDao" ref="DepartmentDao" />
</object>

<object id="DepartmentDao" type="App.Data.DepartmentDao" />

Webconfig contains this:

<sectionGroup name="spring">
        <section name="context" type="Spring.Context.Support.WebContextHandler, Spring.Web"/>
    </sectionGroup>
</configSections>
<spring>
    <context>
        <resource uri="~/Resources/objects.xml" />
    </context>
</spring>

I would prefer to use Property injection rather than constructor, but currently neither method is working.

Well, it turned out to be that ASP.NET MVC and Spring.NET just don’t get along…

However, the MvcContrib package (actually, the Extras package) seems to have solved the issue. The package had a Spring Controller factory implementation that worked, and everything was happy.

(Kind of reminds me of trying to make Struts 1.X and Spring work on the Java side…)
