SimpleJobFactory工廠類定義了生成Job任務的過程：利用反射機制呼叫無參建構函式形成的Job例項

很多時候，定義的Job任務依賴了其他服務(該Job定義有參建構函式)，此時預設的SimpleJobFactory不能滿足例項化要求，考慮自定義Job工廠類。

   public class CustomizeJobFactory : IJobFactory
    {
        /// <summary>
        /// 容器提供器，
        /// </summary>
        protected
 
 IServiceProvider _serviceProvider;

        public CustomizeJobFactory(IServiceProvider serviceProvider)
        {
            _serviceProvider = serviceProvider;
        }

        /// <summary>
        /// 返回IJob
        /// </summary>
        /// <param name="bundle"></param>
        /// <param name="scheduler"></param>
 

        /// <returns></returns>
        public IJob NewJob(TriggerFiredBundle bundle, IScheduler scheduler)
        {
            //Job型別
            Type jobType = bundle.JobDetail.JobType;

            //返回jobType對應型別的例項
            return _serviceProvider.GetService(jobType) as IJob;
        }

        
 
/// <summary>
        /// 清理銷燬IJob
        /// </summary>
        /// <param name="job"></param>
        public void ReturnJob(IJob job)
        {
            var disposable = job as IDisposable;

            disposable?.Dispose();
        }

    }
