Odata 接收“路径的控制器未找到或未实现 IController”答案

【问题标题】：Odata receiving "The controller for path was not found or does not implement IController"Odata 接收“路径的控制器未找到或未实现 IController”

【问题描述】：

我对 Odata 和 Web Api 有点陌生。我从 Fiddler 中的 get 请求中收到此错误：

路径“/odata/Unit”的控制器未找到或未实现 IController

public class UnitController : EntitySetController<Unit, Guid>
{
    public DEVEntities _Context { get; set; }

    public UnitController()
    {
        this._Context = new DEVEntities();
    }

    public override IQueryable<Unit> Get()
    {
        return _Context.UnitSet;
    }

    protected override void Dispose(bool disposing)
    {
        base.Dispose(disposing);
        _Context.Dispose();
    }
}

我的 WebApiConfig.cs

    public static void Register(HttpConfiguration config)
    {
        ODataModelBuilder builder = new ODataModelBuilder();
        builder.EntitySet<Unit>("Units");
        config.Routes.MapODataRoute("odata", "odata", builder.GetEdmModel());

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

I can get http://server/odata/$metadata with no problems but when I try:

but when I try http://server/odata/Unit I get:

[HttpException]: The controller for path &#39;/odata/Unit&#39; was not found or does  not implement IController.

   at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

请帮助我变得非常沮丧。

【解决方案1】：

我以为你的 UnitController 或 EntitySetController 没有继承 ApiController

【解决方案2】：

我找到了答案，我必须将 ODataModelBuilder 更改为 ODataConventionModelBuilder。

这解决了问题。

并且应该将“Units”更改为“Unit”以映射到正确的控制器。
