asp.net core mvc 使用quartz

参照了：https://www.cnblogs.com/dangzhensheng/p/10496278.html

1.新建任务类ReportJob.cs，这个类里就是具体任务了。

using Quartz;
using System;
using System.IO;
using System.Threading.Tasks;

namespace WebApplication1.MyQuartzJob
{

    /// <summary>
    /// 具体任务类
    /// </summary>
    [DisallowConcurrentExecution]
    public class ReportJob : IJob
    {
        public Task Execute(IJobExecutionContext context)
        {
            return Task.Run(() =>
            {
                foo();
            });
        }

        public void foo()
        {
            try
            {
                string root = Directory.GetCurrentDirectory();
                string logDir = Path.Combine(root, "Logs");
                logDir = Path.Combine(logDir, DateTime.Now.ToString("yyyy-MM"));
                var reportDirectory = logDir;

                if (!Directory.Exists(reportDirectory))
                {
                    Directory.CreateDirectory(reportDirectory);
                }
                var dailyReportFullPath = Path.Combine(reportDirectory, DateTime.Now.ToString("yyyy-MM-dd")+".txt");
                var logContent = string.Format("{0}==>>{1}{2}", DateTime.Now, "create new log.", Environment.NewLine);
                File.AppendAllText(dailyReportFullPath, logContent);

            }
            catch (Exception ex)
            {
                //日志
            }
        }
    }
}

foo() 方法就是想要做的任务。

2.新建QuartzFactory类，这个类复制粘贴就行。

using Quartz;
using Quartz.Spi;
using System;

namespace WebApplication1.MyQuartzJob
{
    /// <summary>
    /// 工厂，复制就行
    /// </summary>
    public class QuartzFactory : IJobFactory
    {
        private readonly IServiceProvider _serviceProvider;

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

        public IJob NewJob(TriggerFiredBundle bundle, IScheduler scheduler)
        {
            var jobDetail = bundle.JobDetail;

            var job = (IJob)_serviceProvider.GetService(jobDetail.JobType);
            return job;
        }

        public void ReturnJob(IJob job)
        {
        }
    }
}

3.新建QuartzService类，本类用来定时，和对IServiceCollection进行配置。

using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.DependencyInjection.Extensions;
using Quartz;
using Quartz.Impl;
using Quartz.Spi;
using System;
using System.Collections.Generic;
using System.Linq;

namespace WebApplication1.MyQuartzJob
{
    /// <summary>
    /// 制定任务，配置IServiceCollection
    /// </summary>
    public static class QuartzService
    {
        #region 单任务
        public static void StartJob<TJob>() where TJob : IJob
        {

            string thisJob = "ReportJob";

            string groupName = "gp" + thisJob;
            string jobName = "job" + thisJob;
            string triggerName = "trigger" + thisJob;


            var scheduler = new StdSchedulerFactory().GetScheduler().Result;

            var job = JobBuilder.Create<TJob>()
              .WithIdentity(jobName, groupName)
              .Build();

            var trigger1 = TriggerBuilder.Create()
              .WithIdentity(triggerName, groupName)
              .StartNow()
              .WithSimpleSchedule(x => x.WithIntervalInSeconds(10).RepeatForever())
              .ForJob(job)
              .Build();

            scheduler.AddJob(job, true);
            scheduler.ScheduleJob(job, trigger1);
            scheduler.Start();
        }
        #endregion

        #region 多任务
        public static void StartJobs<TJob>() where TJob : IJob
        {
            var scheduler = new StdSchedulerFactory().GetScheduler().Result;

            var job = JobBuilder.Create<TJob>()
              .WithIdentity("jobs")
              .Build();

            var trigger1 = TriggerBuilder.Create()
              .WithIdentity("job.trigger1")
              .StartNow()
              .WithSimpleSchedule(x => x.WithInterval(TimeSpan.FromSeconds(5)).RepeatForever())
              .ForJob(job)
              .Build();

            var trigger2 = TriggerBuilder.Create()
              .WithIdentity("job.trigger2")
              .StartNow()
              .WithSimpleSchedule(x => x.WithInterval(TimeSpan.FromSeconds(11)).RepeatForever())
              .ForJob(job)
              .Build();

            var dictionary = new Dictionary<IJobDetail, IReadOnlyCollection<ITrigger>>
              {
                {job, new HashSet<ITrigger> {trigger1, trigger2}}
              };

            scheduler.ScheduleJobs(dictionary, true);
            scheduler.Start();
        }
        #endregion

        #region 配置
        public static void AddQuartz(this IServiceCollection services, params Type[] jobs)
        {
            services.AddSingleton<IJobFactory, QuartzFactory>();
            services.Add(jobs.Select(jobType => new ServiceDescriptor(jobType, jobType, ServiceLifetime.Singleton)));

            services.AddSingleton(provider =>
            {
                var schedulerFactory = new StdSchedulerFactory();
                var scheduler = schedulerFactory.GetScheduler().Result;
                scheduler.JobFactory = provider.GetService<IJobFactory>();
                scheduler.Start();
                return scheduler;
            });
        }
        #endregion

    }
}

StartJob 是制定任务，AddQuartz 配置IServiceCollection。

4.在Startup.cs中注册代码

（a） 在public void ConfigureServices(IServiceCollection services) 方法尾部添加一行：services.AddQuartz(typeof(ReportJob));

public void ConfigureServices(IServiceCollection services)
        {
           // 。。。。

            services.AddQuartz(typeof(ReportJob));
        }

注意要引用QuartzService类的命名空间。

（b）在 public void Configure(IApplicationBuilder app, IWebHostEnvironment env)  方法尾部添加一行：QuartzService.StartJob<ReportJob>();

public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
        {
            //....

            QuartzService.StartJob<ReportJob>();
        }

5. F5 运行。
