Quartz 失败的 Azure Web 作业

Question

我已经将控制台应用程序发布为连续运行的 Web 作业，并使用 Quartz 来管理调度。

当我在本地运行该文件时，Quartz 工作正常。

当我将文件作为 Web 作业运行时，我可以看到它按计划运行，并且执行了预期的操作。

但是，当我查看网络作业日志时，我看到如下错误:

[07/06/2017 09:48:59 > dd118a: ERR ] Unhandled Exception: System.IO.FileNotFoundException: Could not load file or assembly 'Quartz, Version=2.5.0.0, Culture=neutral, PublicKeyToken=f6b8c98a402cc8a4' or one of its dependencies. The system cannot find the file specified.

我在这里看到了其他类似的问题，但这通常涉及人们在本地计算机上遇到程序集不匹配问题。

如何检查此错误是否严重，以及如何修复它？

建议？

我使用 Quartz.NET 库 (v2.5.0) 使用以下示例代码进行了测试，它在本地和部署为 WebJobs 上都运行良好。

using Quartz;
using Quartz.Impl;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading;
using System.Threading.Tasks;

namespace QuartzTest
{
    class Program
    {
        static void Main(string[] args)
        {
            try
            {
                Common.Logging.LogManager.Adapter = new Common.Logging.Simple.ConsoleOutLoggerFactoryAdapter { Level = Common.Logging.LogLevel.Info };

                // Grab the Scheduler instance from the Factory 
                IScheduler scheduler = StdSchedulerFactory.GetDefaultScheduler();

                // and start it off
                scheduler.Start();

                // define the job and tie it to our HelloJob class
                IJobDetail job = JobBuilder.Create<HelloJob>()
                    .WithIdentity("job1", "group1")
                    .Build();

                // Trigger the job to run now, and then repeat every 10 seconds
                ITrigger trigger = TriggerBuilder.Create()
                    .WithIdentity("trigger1", "group1")
                    .StartNow()
                    .WithSimpleSchedule(x => x
                        .WithIntervalInSeconds(10)
                        .RepeatForever())
                    .Build();

                // Tell quartz to schedule the job using our trigger
                scheduler.ScheduleJob(job, trigger);

                // some sleep to show what's happening
                Thread.Sleep(TimeSpan.FromSeconds(60));

                // and last shut down the scheduler when you are ready to close your program
                scheduler.Shutdown();
            }
            catch (SchedulerException se)
            {
                Console.WriteLine(se);
            }

            //Console.WriteLine("Press any key to close the application");
            //Console.ReadKey();

        }

        public class HelloJob : IJob
        {
            public void Execute(IJobExecutionContext context)
            {
                Console.WriteLine("Greetings from HelloJob!");
            }
        }

    }
}

WebJobs 日志

Could not load file or assembly 'Quartz, Version=2.5.0.0, Culture=neutral, PublicKeyToken=f6b8c98a402cc8a4' or one of its dependencies. The system cannot find the file specified.

请使用the Kudu Console访问站点的文件夹并确保 Quartz 及其依赖项文件在那里 (D:\home\site\wwwroot\app_data\jobs\continuous{jobname})。您可以尝试删除作业并将其重新部署到 Azure Web 应用程序。

此外，Azure WebJob itself can be triggered on a schedule ，如果可能的话，你可以使用它。
