Quartz With Hosted Services演示

轻量级演示，Quartz大部分设置使用了默认值

演示源代码

1. 新建项目 && 安装Nuget包

   1. 新建ClassLibrary(QuartzJobService1)，负责定义Job处理业务逻辑
   2. 新建WorkerService(QuartzWorkerService1)，项目引用QuartzJobService1，负责配置和启动Quartz，该项目也可替换成其他启动项目，比如Asp.NetCore

   Project	Install Package	#
   QuartzJobService1	Quartz	需要实现 IJob
   QuartzWorkerService1	Quartz.Extensions.Hosting	集成 hosted services
   	Quartz.Plugins	解析 quartz_job_data.xml

2. 修改 Program.cs

   IHost host = Host.CreateDefaultBuilder(args)
    .ConfigureServices((context,services) =>
    {
        //required
        services.AddQuartz(q =>
        {
        });
   
        services.AddQuartzHostedService(options =>
        {
            // when shutting down we want jobs to complete gracefully
            options.WaitForJobsToComplete = true;
        });
   
        //services.AddHostedService<Worker>();
    })
    .Build();
   

3. F5调试查看效果

4. QuartzJobService1 新建 TheJob.cs

   namespace QuartzJobService1
   {
       public class TheJob : IJob
       {
           private readonly ILogger _logger;
   
           public TheJob(ILogger<TheJob> logger)
           {
               _logger = logger;
           }
   
           public Task Execute(IJobExecutionContext context)
           {
               _logger.LogInformation($"{nameof(TheJob)}: {DateTime.Now:G}");
               return Task.CompletedTask;
           }
       }
   }
   

5. 编辑 Program.cs

   services.Configure<QuartzOptions>(context.Configuration.GetSection("Quartz"));
   services.AddTransient<TheJob>();
   
   //required
   services.AddQuartz(q =>
   {
       q.UseMicrosoftDependencyInjectionJobFactory();
   });
   

6. 编辑 appsettings.Development.json

   {
      "Logging": {
        ...
      },
      "Quartz": {
        "quartz.plugin.jobInitializer.type": "Quartz.Plugin.Xml.XMLSchedulingDataProcessorPlugin,Quartz.Plugins",
        "quartz.plugin.jobInitializer.fileNames": "quartz_job_data.xml",
        "quartz.plugin.jobInitializer.failOnFileNotFound": true
      }
    }
   

7. QuartzWorkerService1 新建 quartz_job_data.xml

   <?xml version="1.0" encoding="utf-8" ?>
   <job-scheduling-data xmlns="http://quartznet.sourceforge.net/JobSchedulingData">
     <schedule>
       <job>
         <name>theJob</name>
         <job-type>QuartzJobService1.TheJob, QuartzJobService1</job-type>
       </job>
       <trigger>
         <cron>
           <name>theJobTrigger</name>
           <job-name>theJob</job-name>
           <cron-expression>0/2 * * * * ?</cron-expression>
         </cron>
       </trigger>
     </schedule>
   </job-scheduling-data>
   

8. 部署：发布直接执行QuartzWorkerService1.exe即可

9. 增加Windows服务部署

   1. QuartzWorkerService1 安装Nuget包 Microsoft.Extensions.Hosting.WindowsServices

   2. Edit Program

      IHost host = Host.CreateDefaultBuilder(args)
          .ConfigureServices((context, services) =>
          {
             ...
          })
          .UseWindowsService()
          .Build();
      

   3. cmd

      sc.exe create QuartzWorkerService1 binPath=%~dp0QuartzWorkerService1.exe start=auto
      sc.exe start QuartzWorkerService1
      sc.exe stop QuartzWorkerService1
      sc.exe delete QuartzWorkerService1
