.Net Core 3.1 +Topshelf+Quartz創建Windows定時任務

准備工作

• 創建.net core 控制台應用程序，這里不做過多介紹
• 添加TopShelf包：TopShelf；
• 添加Quartz包：Quartz、Quartz.Plugins；
• 添加依賴注入包：Microsoft.Extensions.DependencyInjection；
• 添加讀取配置文件包：Microsoft.Extensions.Configuration.Json；
• 添加訪問數據庫包：Microsoft.EntityFrameworkCore；

配置Quartz

• 創建appsettings.json文件，右鍵文件屬性，並更改屬性為始終復制 內容

  {
  "quartz": {
      "scheduler": {
        "instanceName": "Job"
      },
      "threadPool": {
        "type": "Quartz.Simpl.SimpleThreadPool, Quartz",
        "threadPriority": "Normal",
        "threadCount": 10
      },
      "plugin": {
        "jobInitializer": {
          "type": "Quartz.Plugin.Xml.XMLSchedulingDataProcessorPlugin, Quartz.Plugins",
          "fileNames": "quartz_jobs.xml"
        }
      }
    }
  }
  

  　

• 創建QuartzOption 類

      public class QuartzOption
      {
          public QuartzOption(IConfiguration config)
          {
              if (config == null)
              {
                  throw new ArgumentNullException(nameof(config));
              }
  
              var section = config.GetSection("quartz");
              section.Bind(this);
          }
  
          public Scheduler Scheduler { get; set; }
  
          public ThreadPool ThreadPool { get; set; }
  
          public Plugin Plugin { get; set; }
  
          public NameValueCollection ToProperties()
          {
              var properties = new NameValueCollection
              {
                  ["quartz.scheduler.instanceName"] = Scheduler?.InstanceName,
                  ["quartz.threadPool.type"] = ThreadPool?.Type,
                  ["quartz.threadPool.threadPriority"] = ThreadPool?.ThreadPriority,
                  ["quartz.threadPool.threadCount"] = ThreadPool?.ThreadCount.ToString(),
                  ["quartz.plugin.jobInitializer.type"] = Plugin?.JobInitializer?.Type,
                  ["quartz.plugin.jobInitializer.fileNames"] = Plugin?.JobInitializer?.FileNames
              };
  
              return properties;
          }
      }
  
      public class Scheduler
      {
          public string InstanceName { get; set; }
      }
  
      public class ThreadPool
      {
          public string Type { get; set; }
  
          public string ThreadPriority { get; set; }
  
          public int ThreadCount { get; set; }
      }
  
      public class Plugin
      {
          public JobInitializer JobInitializer { get; set; }
      }
  
      public class JobInitializer
      {
          public string Type { get; set; }
          public string FileNames { get; set; }
      }
  
  

  　　

• 添加一個Job

  public class TestJob : IJob
      {
          private readonly IService _service;
  
          public SyncJob(IService service)
          {
              _service = service;
          }
  
          public async Task Execute(IJobExecutionContext context)
          {
              Log.Information("同步開始...");
              _service.DoSomeThing();
          }
      }
  

  　　

• 實現IJobFactory

  public class JobFactory : IJobFactory
      {
          protected readonly IServiceProvider Container;
  
          public JobFactory(IServiceProvider container)
          {
              Container = container;
          }
  
          public IJob NewJob(TriggerFiredBundle bundle, IScheduler scheduler)
          {
              return Container.GetService(bundle.JobDetail.JobType) as IJob;
          }
  
          public void ReturnJob(IJob job)
          {
              (job as IDisposable)?.Dispose();
          }
      }
  

  　　

• 創建Quartz調度的配置文件 quartz_jobs.xml

  <?xml version="1.0" encoding="UTF-8"?>
  
  <!-- This file contains job definitions in schema version 2.0 format -->
  
  <job-scheduling-data xmlns="http://quartznet.sourceforge.net/JobSchedulingData" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.0">
  
    <processing-directives>
      <overwrite-existing-data>true</overwrite-existing-data>
    </processing-directives>
  
      <schedule>
        <!--TestJob測試 任務配置-->
        <job>
          <name>TestJob</name>
          <group>ServerGroup</group>
          <description>上傳視頻</description>

          <recover>false</recover>
        </job>
        <trigger>
          <cron>

            <job-group>ServerGroup</job-group>
            <cron-expression>0/60 * * * * ?</cron-expression>
          </cron>
        </trigger>
  
        <!--TestJob2測試 任務配置-->
        <!--
      <job>
        <name>TestJob2</name>
        <group>Test</group>

        <job-type>CoreSolution.Job.jobs.TestJob2,CoreSolution.Job</job-type>
        <durable>true</durable>
        <recover>false</recover>
      </job>
      <trigger>
        <cron>

          -->
        <!--30s執行一次-->
        <!--
        </cron>
      </trigger>-->
  
      </schedule>
    </job-scheduling-data>
  

  　　

• 添加一個類，此類用戶服務啟動調用

• public sealed class ServiceRunner : ServiceControl, ServiceSuspend
      {
          //調度器
          private readonly IScheduler scheduler;
          public ServiceRunner()
          {
  
              scheduler = StdSchedulerFactory.GetDefaultScheduler().GetAwaiter().GetResult();
  
          }
          //開始
          public bool Start(HostControl hostControl)
          {
              scheduler.Start();
              return true;
          }
          //停止
          public bool Stop(HostControl hostControl)
          {
              scheduler.Shutdown(false);
              return true;
          }
          //恢復所有
          public bool Continue(HostControl hostControl)
          {
              scheduler.ResumeAll();
              return true;
          }
          //暫停所有
          public bool Pause(HostControl hostControl)
          {
              scheduler.PauseAll();
              return true;
          }
      }
  

  　　

• 配置TopShelf

  class Program
      {
          static void Main(string[] args)
          {
              var rc = HostFactory.Run(x =>
              {
                 x.Service<ServiceRunner>(s => {
                      s.ConstructUsing(name => new ServiceRunner());
                      s.WhenStarted((tc, hc) => tc.Start(hc));
                      s.WhenStopped((tc, hc) => tc.Stop(hc));
                      s.WhenContinued((tc, hc) => tc.Continue(hc));
                      s.WhenPaused((tc, hc) => tc.Pause(hc));
                  });
  
                  x.RunAsLocalService();
                  x.StartAutomaticallyDelayed();
                  x.RunAsLocalSystem();
  
                  x.SetDescription("測試后台服務");
                  x.SetDisplayName("TestServer");
                  x.SetServiceName("TestServer");
                  x.EnablePauseAndContinue();
              });
              var exitCode = (int)Convert.ChangeType(rc, rc.GetTypeCode());
              Environment.ExitCode = exitCode;
          }
      }
