所请求的服务 ' 尚未使用 autofac 在 Quartz.net 中注册

Question

我正在使用 autofac 注册 Quartz，但我运行遇到了一个问题，我得到了这个：

The requested service 'AuthMatcher.ConsumerSchechuler.ConsumerSchechulerJob' has not been registered. To avoid this exception, either register a component to provide the service, check for service registration using IsRegistered(), or use the ResolveOptional() method to resolve an optional dependency.

当在 jobFactory :IjobFactory 中调用 NewJob 方法时 class.

工厂类：

    using Autofac;
using Microsoft.Extensions.DependencyInjection;
using Quartz;
using Quartz.Spi;
using System;

namespace AuthMatcher.ConsumerSchechuler
{
    public class ConsumerJobFactory : IJobFactory
    {
        private IScheduler _scheduler;
        private readonly IContainer _container;
        public ConsumerJobFactory(IContainer container)
        {
            _container = container;
        }

        public IJob NewJob(TriggerFiredBundle bundle, IScheduler scheduler)
        {
            //test to see what happenes, it returns null
            var service =  _container.ResolveOptional<ConsumerSchechulerJob>();
          // this is where the exception happens
            return (IJob)_container.Resolve(bundle.JobDetail.JobType);
        }

        public void ReturnJob(IJob job) { }
    }
}

Autofac 启动class:

namespace Workers
{
    public class InstallerClass
    {
        private static readonly ILogger Logger = LogManager.GetCurrentClassLogger();

        public static IContainer Startup()
        {
            var builder = new ContainerBuilder();
            builder.RegisterType<Application>().As<IApplication>();
            builder.RegisterType<RabbitMQImpl>().As<IQueue>().SingleInstance();
            builder.RegisterType<ConsumeSchechuler>().As<IConsumeSchechuler>();
            builder.RegisterType<BotFactory>().As<IBotFactory>();
            var instance = QuartzInstance.Instance;
            builder.RegisterType<ConsumerSchechulerJob>().As<IJob>();
            builder.RegisterInstance(QuartzInstance.Instance).As<IScheduler>();

            return builder.Build();

        }
    }

}

main class 正在调用安装并实例化 JobFactory 我将从启动 class 获得的容器及其所有依赖项传递给 ConsumerJobFactory。

namespace Workers
{
    class Program
    {
        static void Main(string[] args)
        {

            var container = InstallerClass.Startup();
            using (var scope = container.BeginLifetimeScope())
            {

                var app = scope.Resolve<IApplication>();
                var _scheduler = container.Resolve<IScheduler>();
                _scheduler.JobFactory = new ConsumerJobFactory(container);
                app.Run();

            }
        }
    }
}

任何帮助都将不胜感激，因为在此问题上停留了太久

The requested service AuthMatcher.ConsumerSchechuler.ConsumerSchechulerJob has not been registered. To avoid this exception, either register a component to provide the service, check for service registration using IsRegistered(), or use the ResolveOptional() method to resolve an optional dependency.

此错误消息表示 ConsumerSchechulerJob 尚未注册。如果您查看您的注册

 builder.RegisterType<ConsumerSchechulerJob>().As<IJob>();

您将 ConsumerSchechulerJob 注册为 IJob 而不是 ConsumerSchechulerJob，因此 Autofac 没有任何 ConsumerSchechulerJob 的注册。要解决此问题，您应该注册它。

 builder.RegisterType<ConsumerSchechulerJob>()
        .As<IJob>()
        .As<ConsumerSchechulerJob>();

或

 builder.RegisterType<ConsumerSchechulerJob>()
        .As<IJob>()
        .AsSelf();
