Question

I’m trying to get a simple Spring.NET webservice working with MVC3 but although there are no errors, and I can see from the logs that Spring is deploying it, I can’t htt the correct URL for my web service at all.

I think I’ve followed the example (that comes with Spring.NET) correctly. Mine differs in that I’m not doing any AOP weaving on my service. As far as I can tell, it should work…. but doesn’t.

Here’s my service class (very basic)

public interface IHelloService
{
    string SayHello();
}

public class HelloService : IHelloService
{
    public String SayHello()
    {
        return "Hello";
    }
}

And here’s my config

<!-- Web services -->
<object id="HelloService" type="Munch.Service.Web.HelloService, Munch.Service"/>

<!-- Exports contact service (weaved or not) as a web service. -->
<object id="HelloWebService" type="Spring.Web.Services.WebServiceExporter, Spring.Web">
  <property name="TargetName" value="HelloService"/>
  <property name="Namespace" value="http://Munch.Service.Web/HelloService"/>
  <property name="Description" value="Hello Web Services"/>
  <property name="TypeAttributes">
    <list>
      <object type="System.Web.Script.Services.ScriptServiceAttribute, System.Web.Extensions"/>
    </list>
  </property>
</object>

I would expect to be able to access my web service at something like http://localhost:8080/Munch/HelloWebService.asmx but no joy with any of the variations I have tried. Is there a way to find out what web services have been deployed (some debug page perhaps)?

The example that comes with Spring does actually work(!) so I know it’s possible to get a working Spring WS on my machine, I just can’t see where I’ve gone wrong.

I was able to use to publish your HelloService in the spring.net Spring.Mvc3QuickStart that ships with spring.net 1.3.2.

These were the things I had to do to get it to work:

1. Add the service configuration to the spring.net mvc context
2. Add all asmx resources to routes.IgnoreRoute
3. Add the Spring.Web.Services.WebServiceHandlerFactory from Spring.Web, as bbaia had commented on your question

I suspect you’ve forgotten to add all asmx resources to routes.IgnoreRoute.

Step-by-step

Start with the Spring.Mvc3QuickStart example application that ships with Spring.Net 1.3.2.

Reference the project that contains the HelloService class from your question.

Add a file ~/Config/services.xml to the project, containing your service configuration:

<object id="HelloService" type="Munch.Service.Web.HelloService, Munch.Service"/>

<object id="HelloWebService" type="Spring.Web.Services.WebServiceExporter, Spring.Web">
  <property name="TargetName" value="HelloService"/>
  <property name="Namespace" value="http://Munch.Service.Web/HelloService"/>
  <property name="Description" value="Hello Web Services"/>
  <property name="TypeAttributes">
    <list>
      <object type="System.Web.Script.Services.ScriptServiceAttribute, System.Web.Extensions"/>
    </list>
  </property>
</object>

In Global.asax, add

routes.IgnoreRoute("{resource}.asmx/{*pathInfo}");

to RegisterRoutes. This will tell the asp.net mvc handler to leave requests to asmx resources alone.

In web.config, add the following http handler:

<system.web>
  <!-- ... -->
  <httpHandlers>
    <add verb="*" path="*.asmx" type="Spring.Web.Services.WebServiceHandlerFactory, Spring.Web" />
  </httpHandlers>
  <!-- ... -->

In web.config, add your service configuration to the spring context:

<spring>
  <context>
    <resource uri="file://~/Config/controllers.xml" />
    <resource uri="file://~/Config/services.xml" />
  </context>
</spring>

When you run the application from Visual Studio, you should be able to view the service at http://localhost:12345/HelloWebService.asmx (replace 12345 with you dev port).

Notes

I’m unfamiliar with asp.net-mvc, so there might be better ways to configure it than I’ve suggested.
