一、依赖下载

Quartz

二、基础使用

2.1 创建任务

 internal class SendMessageJob : IJob
{
    public async Task Execute(IJobExecutionContext context)
    {
        await Task.Run(() =>
        {
            Console.WriteLine("hello:" + DateTime.Now);
        });

    }
}

2.2 任务初始化

public async static Task Init()
{
    #region 创建单元
    var factory = new StdSchedulerFactory();
    IScheduler task = await factory.GetScheduler();
    await task.Start();
    #endregion

    // job 作业
    IJobDetail jobDetail = JobBuilder.Create<SendMessageJob>()
        .WithIdentity("sendMessageJob","group1")
        .WithDescription("this is send message job")
        .Build();

    // trigger 事件策略
    ITrigger trigger = TriggerBuilder.Create()
        .WithIdentity("sendMessageTriageer", "group")
        .StartNow()
        .WithSimpleSchedule(w=>w.WithIntervalInSeconds(1).WithRepeatCount(3))
        .Build();

    // 将事件策略和作业承载到单元上
    await task.ScheduleJob(jobDetail, trigger);
}

2.3 任务调度

MyFunction.Init().GetAwaiter().GetResult();

2.4 使用演示

注意，实际运行次数会比要求次数多一次

三、更多细节

3.1 参数传递

有 JobDetail、Trigger、Merged 三种方式

3.1.1 参数提供

using Quartz;
using Quartz.Impl;
using quartz_01.CustomerJob;

namespace quartz_01
{
    public  class MyFunction
    {
      public async static Task Init()
        {
            #region 创建单元
            var factory = new StdSchedulerFactory();
            IScheduler task = await factory.GetScheduler();
            await task.Start();
            #endregion

            // job 作业
            IJobDetail jobDetail = JobBuilder.Create<SendMessageJob>()
                .WithIdentity("sendMessageJob","group1")
                .WithDescription("this is send message job")
                .Build();

            // 传入参数
            jobDetail.JobDataMap.Add("user1","zhangsan");
            jobDetail.JobDataMap.Add("user2", "lisi");
            jobDetail.JobDataMap.Add("year", DateTime.Now.Year);

            // trigger 事件策略
            ITrigger trigger = TriggerBuilder.Create()
                .WithIdentity("sendMessageTriageer", "group")
                .StartNow()
                .WithSimpleSchedule(w=>w.WithIntervalInSeconds(1))
                .Build();

            // 传入参数
            trigger.JobDataMap.Add("user3", "zhangsan");
            trigger.JobDataMap.Add("user4", "lisi");
            trigger.JobDataMap.Add("year", DateTime.Now.Year + 1);

            // 将事件策略和作业承载到单元上
            await task.ScheduleJob(jobDetail, trigger);
        }

    }
}

3.1.2 参数接收

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

namespace quartz_01.CustomerJob
{
    internal class SendMessageJob : IJob
    {
        public async Task Execute(IJobExecutionContext context)
        {
            await Task.Run(() =>
            {
                Object v1 = context.JobDetail.JobDataMap.Get("user1");
                string v2 = context.JobDetail.JobDataMap.GetString("user2");
                int y1 = context.JobDetail.JobDataMap.GetInt("year");

                Object v3 = context.Trigger.JobDataMap.Get("user3");
                string v4 = context.Trigger.JobDataMap.GetString("user4");
                int y2 = context.Trigger.JobDataMap.GetInt("year");

                // 此方法也可取值，当JobDetail和Trigger都存在值时，取后者值覆盖
                // 若两者只有一个有值，则取有值的那个
                int y3 = context.MergedJobDataMap.GetInt("year");

                Console.WriteLine("------- JobDetail --------");
                Console.WriteLine(v1);
                Console.WriteLine(v2);
                Console.WriteLine(y1);
                Console.WriteLine("------- Trigger --------");
                Console.WriteLine(v3);
                Console.WriteLine(v4);
                Console.WriteLine(y2);
                Console.WriteLine("------- Merged --------");
                Console.WriteLine(y3);
            });
            
        }
    }
}
