c# - 如何将 WebApi 2 与 Spring.Net 集成

Question

我尝试将 WebApi 2 与 Spring.Net 集成，但没有成功。这是我尝试过的:

public class MvcApplication : SpringMvcApplication
{
    protected void Application_Start()
    {
        XmlConfigurator.Configure();

        AreaRegistration.RegisterAllAreas();
        GlobalConfiguration.Configure(WebApiConfig.Register);
        FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
        RouteConfig.RegisterRoutes(RouteTable.Routes);
        BundleConfig.RegisterBundles(BundleTable.Bundles);
    }
}

在创建 SpringWebApiDependencyResolver 实例时，出现以下异常:

创建上下文“spring.root”时出错:请求在此上下文中不可用

public static class WebApiConfig
{
    public static void Register(HttpConfiguration config)
    {
        config.DependencyResolver = new SpringWebApiDependencyResolver(ContextRegistry.GetContext());

        config.Routes.MapHttpRoute(
            name: "DefaultApi",
            routeTemplate: "api/{controller}/{id}",
            defaults: new { id = RouteParameter.Optional }
        );
    }
}

我正在使用 Spring.Net 2.0.1

现在可以正常工作了，不需要下面这行:

config.DependencyResolver = new SpringWebApiDependencyResolver(ContextRegistry.GetContext());

这是我基于Spring.Net的实现example :

public class MvcApplication : SpringMvcApplication
{
    protected void Application_Start()
    {
        // More config...
        GlobalConfiguration.Configure(WebApiConfig.Register);
        // More config...
    }

    protected override System.Web.Http.Dependencies.IDependencyResolver BuildWebApiDependencyResolver()
    {
        var resolver = base.BuildWebApiDependencyResolver();

        var springResolver = resolver as SpringWebApiDependencyResolver;

        if (springResolver != null)
        {
            var resource = new AssemblyResource(
                "assembly://assemblyName/namespace/ChildControllers.xml");
            springResolver.AddChildApplicationContextConfigurationResource(resource);
        }

        return resolver;
    }
}

我更喜欢保留常见的 WebApi 配置:

public static class WebApiConfig
{
    public static void Register(HttpConfiguration config)
    {
        config.Routes.MapHttpRoute(
            name: "DefaultApi",
            routeTemplate: "api/{controller}/{id}",
            defaults: new { id = RouteParameter.Optional }
        );
    }
}

在 IoC 容器中注册 Controller 与 MVC 集成相同:

<object type="namespace.PrefixController, assemblyName" singleton="false" >
    <property name="Dependency1" ref="Dependency1" />
</object>
