在我的XXXX.WS WCF服务项目中,我正在尝试使用autofac进行DI / IOC ...整天都在使用它但是我认为我很接近(这里有不同的错误)......这个错误我无法理解如何动摇......“必须设置AutofacServieHost.Container静态属性......”但我想我正在设置它!?!我做错了什么?
protected void Application_Start(object sender, EventArgs e)
{
var builder = new ContainerBuilder();
builder.Register(c => new DatabaseFactory()).As<IDatabaseFactory>().Named<DatabaseFactory>("DBFactory");
builder.Register(c => new ListingSqlRepository(c.ResolveNamed<DatabaseFactory>("DBFactory"))).As<IListingSqlRepository>().Named<ListingSqlRepository>("LSR");
builder.Register(c => new ListingRepository(c.ResolveNamed<ListingSqlRepository>("LSR"))).As<IListingRepository>().Named<ListingRepository>("LR");
builder.Register(c => new Service1(c.ResolveNamed<IListingRepository>("LR"))).As<IService1>();
using (var container = builder.Build())
{
Uri address = new Uri("http://localhost:57924/Service1");
ServiceHost host = new ServiceHost(typeof(Service1), address);
host.AddServiceEndpoint(typeof(IService1), new BasicHttpBinding(), string.Empty);
host.AddDependencyInjectionBehavior<IService1>(container);
//BREAKS HERE?
host.Description.Behaviors.Add(new ServiceMetadataBehavior { HttpGetEnabled = true, HttpGetUrl = address });
host.Open();
Console.WriteLine("The host has been opened.");
Console.ReadLine();
host.Close();
Environment.Exit(0);
}
}
然后服务: 命名空间LOTW2012.WS {
public class Service1 : IService1
{
private IListingRepository _listingRepository { get; set; }
public Service1(IListingRepository iLR) {
this._listingRepository = iLR;
}
public Service1()
{
}
public List<Listing> GetListingsByStateName(string stateName)
{
//todo ..getall for now
var listings = _listingRepository.GetAll().ToList();
return listings;
}
答案 0 :(得分:6)
您需要通过设置相关属性告诉Autofac WCF集成您构建的容器:
var builder = new ContainerBuilder();
// ...
AutofacHostFactory.Container = builder.Build();
// ...
这将允许Autofac解析服务类型。
