【问题描述】：

您好，我创建了一个自定义作业工厂，如下所示

class JobFactory : IJobFactory
    {
        protected readonly IServiceProvider _container;

        public JobFactory(IServiceProvider container)
        {
            _container = container;
        }

        public IJob NewJob(TriggerFiredBundle bundle, IScheduler scheduler)
        {
            var job = (IJob)_container.GetService(bundle.JobDetail.JobType)!;
            var logTime = _container.GetService<ILogTime>()!;
            return new JobLogDecorator(job,logTime);
        }

        public void ReturnJob(IJob job)
        {
            (job as IDisposable)?.Dispose();
        }
    }

JobLogDecorator 是一个简单的类，用于记录装饰作业所经过的时间

public class JobLogDecorator : IJob
    {
        private readonly IJob _decorated;
        private readonly ILogTime _log;

        public JobLogDecorator (IJob decorated, ILogTime log)
        {
            _decorated = decorated;
            _log = log;
        }

        public async Task Execute(IJobExecutionContext context)
        {
            var jobName = context.JobDetail.Key.Name;
            var sw = Stopwatch.StartNew();

                await _decorated.Execute(context);

                _log.Log(sw.ElapsedMilliseconds, jobName);

        }
    }

现在我想注册石英和这个工作工厂。在启动时我已经注册但我不明白如何注册我的自定义作业工厂

services.AddQuartz(q =>
                {
                    q.SchedulerId = "MyJob";
                    q.SchedulerName = "MyJob";
                    
                    //i try to add this but i cannot hit the JobLogDecorator when the job is running
                    q.UseJobFactory<JobFactory>();
                    //i cannot understand how to configure this method
                    q.UseMicrosoftDependencyInjectionJobFactory();

                });

                services.AddQuartzHostedService(options =>
                {
                    options.WaitForJobsToComplete = true;
                });

因此我无法点击/调用 JobFactory ,JobLogDecorator 我也注册了services.AddSingleton<JobFactory>();

【问题讨论】：

在配置 Quartz 之前，您是否在 DI services.AddSingleton<IJobFactory, JobFactory>() 中注册了工厂？ github.com/quartznet/quartznet/blob/…
@abdusco 我也试试这个，但我无法调用 JobLogDecorator 和 jobfactory

标签： c# asp.net-core .net-core quartz.net

【解决方案1】：

当您想注册您的自定义工厂时，我发现了问题，您必须按照以下步骤操作

注册工厂q.UseJobFactory<JobFactory>();
删除q.UseMicrosoftDependencyInjectionJobFactory();
注册工作而不是工厂，例如，如果我有 MaintenanceJob，我将这个工作注册为 services.AddTransient<MaintenanceJob>();
