wcf - autofac wcf注册错误

Question

我正在尝试在 Wcf 上使用 Autofac 构建结构。

    namespace WcfService1.Model
    {
        [DataContract(IsReference = true)]
        public partial class Account
        {
            [DataMember]
            public int Id { get; set; }
            [DataMember]
            public string Name { get; set; }
            [DataMember]
            public string Surname { get; set; }
            [DataMember]
            public string Email { get; set; }
            [DataMember]
            public Nullable<System.DateTime> CreateDate { get; set; }
        }    
    }

模型>IAccounRepository.cs

1.

namespace WcfService1.Model
{
  public interface IAccountRepository
    {
        IEnumerable<Account> GetAllRows();
        bool AddAccount(Account item);
    }
}

模型>AccounRepository.cs

2.

namespace WcfService1.Model
{
    public class AccountRepository:IAccountRepository
    {
        private Database1Entities _context;
        public AccountRepository()
        {
            if(_context == null)
                _context =new Database1Entities();
        }

        public IEnumerable<Account> GetAllRows()
        {
            if (_context == null)
                _context = new Database1Entities();
            return _context.Account.AsEnumerable();
        }        

        public bool AddAccount(Account item)
        {
            try
            {
                if (_context == null)
                    _context = new Database1Entities();
                _context.Entry(item).State = EntityState.Added;
                _context.Account.Add(item);
                _context.SaveChanges();
                return true;
            }
            catch (Exception ex)
            {
                var str = ex.Message;
                return false;
            }
        }
    }
}

1. DbConnection > EntityFramework + DbContext

2. IService1.cs

代码:

namespace WcfService1
{
    [ServiceContract(SessionMode = SessionMode.Allowed)]
    public interface IService1
    {
        [OperationContract]
        IList<Account> GetAccounts();

        [OperationContract]
        bool AddAccount(Account item);
    }
}

1. Service1.cs

代码:

namespace WcfService1
{
    [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
    public class Service1:IService1
    {
        private readonly IAccountRepository _repository;
        public Service1(IAccountRepository repository)
        {
            _repository = repository;
        }    
        public IList<Account> GetAccounts()
        {   
            var items = _repository.GetAllRows().ToList();
            return items;
        }
        public bool AddAccount(Account item)
        {
            item.CreateDate = DateTime.Now;    
            return _repository.AddAccount(item);
        }
    }
}

1. Service1.svc

代码:

<%@ ServiceHost Language="C#"
                Debug="true"
                Service="WcfService1.Service1, WcfService1"
                Factory="Autofac.Integration.Wcf.AutofacWebServiceHostFactory, Autofac.Integration.Wcf" %>

1. Global.asax.cs

代码:

protected void Application_Start(object sender, EventArgs e)
        {
            var builder = new ContainerBuilder();
            builder.RegisterType< AccountRepository>().As< IAccountRepository>();
            builder.RegisterType< Service1 >().As< IService1>();

            AutofacHostFactory.Container = builder.Build();
        }

我收到以下错误，找不到解决方案。我怎么了。

错误消息:

“/”应用程序中的服务器错误。

Answer 1

除了其他答案之外，您还应该确保在 .svc 文件中 ServiceHost 元素的 Service 属性中使用完全限定的服务名称。

例如，而不是:

<%@ ServiceHost Language="C#" Debug="true" Service="MoviesService.MoviesService" CodeBehind="MoviesService.svc.cs" %>

用途:

<%@ ServiceHost Language="C#" Debug="true" Service="MoviesService.MoviesService, MoviesService" CodeBehind="MoviesService.svc.cs" %>
