Question

我在设置上遇到Hangfire问题。我总是看到这个错误 Hangfire.State表

重试尝试1的10：没有为此obj定义的无参数构造函数... 虽然经过几次重试。它以某种方式自动解决。

我对Autofac并不擅长，只是基本的。我第一次使用Hangfire。

这是我的设置。使用Autofac。

public void Configuration(IAppBuilder app)
{
    GlobalConfiguration.Configuration.UseSqlServerStorage("connectionstring");

    var builder = new ContainerBuilder();

    builder.RegisterType<CSVCompanyAImporter>().Named<ISpecificImporter>("CSVCompanyAImporter").PropertiesAutowired();
    builder.RegisterType<CSVImporter>().Named<IImporter>("CSVImporter").PropertiesAutowired();
    builder.RegisterType<ImportManager>().AsSelf().PropertiesAutowired();

    var container = builder.Build();

    JobActivator.Current = new AutofacJobActivator(container);
    GlobalConfiguration.Configuration.UseAutofacActivator(container);

    app.UseHangfireDashboard();
    app.UseHangfireServer();
}

public class ImportManager
{
    public IImporter Importer { get; set; }
    public IIndex<string, IImporter> Importers { get; set; }
    private bool IsAutofacNamed { get; set; }

    public ImportManager(IImporter importer)
    {
        this.Importer = importer;
        this.IsAutofacNamed = false;
    }

    public ImportManager(IIndex<string, IImporter> importers)
    {
        this.Importers = importers;
        this.IsAutofacNamed = true;
    }

    public void Execute(string importType, string specificImportType)
    {
        if (IsAutofacNamed)
        {
            this.Importer = this.Importers[importType];
            this.Importer.InitializeSpecificImport(specificImportType);
        }

        bool hasFiles = this.Importer.LocateFile();

        if(hasFiles)
        { 
            this.Importer.ReadFile();
            this.Importer.ImportFile();
        }
    }
}

public class CSVImporter : IImporter
{
    public CSVImporter(ISpecificImporter specificImporter)
    {}

    public CSVImporter(IIndex<string, ISpecificImporter> specificImporters)
    {}
}

public class CSVCompanyAImporter : ISpecificImporter
{
    public CSVCompanyAImporter() {}
}

正在调用Hangfire的地方。

protected void btnImport_Click(object sender, EventArgs e)
{
    string importId = "CompanyAImport"

    RecurringJob.AddOrUpdate<ImportManager>(importId, importManager => importManager.Execute("CSVImporter", "CSVCompanyAImporter"), Cron.Minutely);
}

以下是例外情况：

请帮忙。我坚持这个问题。
