Make sure that the controller has a parameterless public constructor.

web调用了wcf，发现是wcf那边出错，连不上数据库导致的。

数据库的ip更换了

DynamicProfileService的接口和服务在Autofac中注册过了。

创建Controller的时候，不知道为啥会自动Resolve对应的Service。

然后Service的实例需要连接数据库，但是又找不到连接字符串。

需要研究一下autofac是如何在mvc中进行resolve操作的，是否不管注册多少，在create controller的时候全部自动resolve

Application_Error方法里面会跳转错误页面

Response.RedirectToRoute(new { controller = "Error", action = "Index" });

因为ErrorController也会触发同样的错误，直接死循环了。

https://github.com/autofac/Autofac.Mvc/blob/develop/src/Autofac.Integration.Mvc/AutofacDependencyResolver.cs#L172

目测是resolve这个DynamicProfileService的时候出错了

  /// <summary>
        /// Get a single instance of a service.
        /// </summary>
        /// <param name="serviceType">Type of the service.</param>
        /// <returns>The single instance if resolved; otherwise, <c>null</c>.</returns>
        public virtual object GetService(Type serviceType)
        {
            return this.RequestLifetimeScope.ResolveOptional(serviceType);
        }
