带有MVC5属性路由的模糊路由

我在使用属性路由时遇到了歧义路由的问题。问题源于(我相信)在我们的路由中使用可变参数。令我烦恼的是，文字参数似乎没有优先级，MVC5无法确定使用哪条路由。

我以前在使用其他路由时遇到过这个问题，并认为通过定义约定路由已经解决了这个问题。考虑到这一点，我在哪里可以找到有关属性路由和解决歧义的最佳实践的更多信息?

这是我遇到问题的代码，以及异常。

'/'应用程序出现服务器错误。

找到多个与URL匹配的控制器类型。如果多个控制器上的属性路由与请求的URL匹配，就会发生这种情况。

RouteConfig.cs

public static void RegisterRoutes(RouteCollection routes)
{
    routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
    // I added this constraint resolver to resolve some other ambiguous routes that end
    // with a literal, but MVC5 wasn't able to determine whether to use those routes
    var constraintResolver = new System.Web.Mvc.Routing.DefaultInlineConstraintResolver();
    constraintResolver.ConstraintMap.Add("notWriteAction", typeof(IsNotWriteActionConstraint));
    routes.MapMvcAttributeRoutes(constraintResolver);
    // This is the convention route I added to resolve another ambiguous route.
    routes.MapRoute(
        name: "Account",
        url: "Account/{action}/{GroupName}/{AccessToken}",
        defaults: new { controller = "Account", action = "Login", GroupName = UrlParameter.Optional, AccessToken = UrlParameter.Optional }
    );
    routes.MapRoute(
        name: "Default",
        url: "{controller}/{action}/{id}",
        defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
    );
}

RoundController.cs

public class RoundController : ControllerBase
{
    [Route("{groupid}/{campaignid}/{accesstoken}")]
    public async Task<ActionResult> TempRoundLink(string groupid, string campaignid, string accesstoken)
    {
    }
}

AccountController.cs

public class AccountController : ControllerBase
{
    [AllowAnonymous]
    [Route("Account/ResetPassword/{token}")]
    public async Task<ActionResult> ResetPassword(string token)
    {
    }
}

[RoutePrefix("Round")]
public class RoundController : ControllerBase
{
    [Route("{groupid}/{campaignid}/{accesstoken}")]
    public async Task<ActionResult> TempRoundLink(string groupid, string campaignid, string accesstoken)
    {
    }
}
[RoutePrefix("Account")]
public class AccountController : ControllerBase
{
    [AllowAnonymous]
    [Route("Account/ResetPassword/{token}")]
    public async Task<ActionResult> ResetPassword(string token)
    {
    }
}

Routes (from attributes):
"Account/ResetPassword/{token}"
"Account/{something}/alpha"
Reequest:
"/Account/ResetPassword/alpha"
