在DI容器或Main方法外调用Quartz.NET调度器的技术问题

问题背景 #

我们计划使用Quartz.NET实现邮件发送、记录复制等定时任务，它适配性良好，但官方文档未针对DI容器及仓储工作单元模式更新相关内容，导致我们遇到了问题。

我们在解决方案中单独创建了JobRunner项目，用于存放调度器及各类Job，这些Job可调用业务服务层接口。当前核心问题是：在JobRunner项目的Main方法实例化调度器后，无法在外部获取该调度器的访问权限。

当前代码 #

Main文件代码 #

private static async Task Main(string[] args)
{
   LogProvider.SetCurrentLogProvider(new ConsoleLogProvider());
   // Grab the Scheduler instance from the Factory
   StdSchedulerFactory factory = new StdSchedulerFactory();
   IScheduler scheduler = await factory.GetScheduler();
   
   // and start it off
   await scheduler.Start();
   
   // and last shut down the scheduler when you are ready to close your program
   await scheduler.Shutdown();
}

典型Job代码 #

using Quartz;
using Compyl.AppLogic.AssessmentService;

namespace JobRunner.Jobs
{
    public class AssessmentDuplicationJob : IJob
    {
        private readonly IAssessmentService _assessmentService;
       
        public AssessmentDuplicationJob(IAssessmentService assessmentService)
        {
            _assessmentService = assessmentService;
          
        }

        public async Task Execute(IJobExecutionContext context)
        {
            var dataMap = context.MergedJobDataMap;
            var id = dataMap.GetInt("id");
            var shouldPopulateAnswers = dataMap.GetBoolean("shouldPopulateAnswers");
            _assessmentService.DuplicateAssessment(id, shouldPopulateAnswers);
        }
    }
}

需求 #

我们希望在JobRunner项目中创建一个通过DI持有调度器的类或方法，示例如下：

[Inject] IScheduler scheduler
public ScheduleEntity (T entity)
{
   var job = createJob(entity)//another method that creates the job and jobdatamap this is easy enough
   var trigger = createTrigger(entity)// same as above
   scheduler.ScheduleJob(job, trigger)
}

随后可以在Web应用的任意位置调用ScheduleEntity方法。
