作业引擎quartz.net --- 监听链

针对多个作业：如何描述各个跑批任务之间的顺序，紧前、紧后关系，实现灵活调度。例如：A完成则B开始，B完成C开始。

对quartz.net 进行了查阅，能实现如上业务，如下图：

测试代码：

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

using Quartz.Listener;

namespace ConsoleApp
{
public class quartznetTest
{
public static void Run()
{

ISchedulerFactory factory = new StdSchedulerFactory();

// Get scheduler and add object
IScheduler scheduler = factory.GetScheduler();

JobKey firstJobKey = JobKey.Create("FirstJob", "Pipeline");
JobKey secondJobKey = JobKey.Create("SecondJob", "Pipeline");
JobKey thirdJobKey = JobKey.Create("ThirdJob", "Pipeline");

// Create job and trigger
IJobDetail firstJob = JobBuilder.Create<SimpleJob1>()
.WithIdentity(firstJobKey)
//.StoreDurably(true)
.Build();

IJobDetail secondJob = JobBuilder.Create<SimpleJob2>()
.WithIdentity(secondJobKey)
.StoreDurably(true)
.Build();

IJobDetail thirdJob = JobBuilder.Create<SimpleJob3>()
.WithIdentity(thirdJobKey)
.StoreDurably(true)
.Build();

ITrigger firstJobTrigger = TriggerBuilder.Create()
.WithIdentity("Trigger", "Pipeline")
.WithSimpleSchedule(x => x
.WithMisfireHandlingInstructionFireNow()
.WithIntervalInSeconds(5)
.RepeatForever())
.Build();

JobChainingJobListener listener = new JobChainingJobListener("Pipeline Chain");
listener.AddJobChainLink(firstJobKey, secondJobKey);
listener.AddJobChainLink(secondJobKey, thirdJobKey);

scheduler.ListenerManager.AddJobListener(listener, GroupMatcher<JobKey>.GroupEquals("Pipeline"));

// Run it all in chain
scheduler.Start();
scheduler.ScheduleJob(firstJob, firstJobTrigger);
scheduler.AddJob(secondJob, false, true);
scheduler.AddJob(thirdJob, false, true);

//Console.ReadLine();
//scheduler.Shutdown();
//Console.WriteLine("Scheduler shutdown.");
//Console.WriteLine(history);
//Console.ReadLine();

}
}
public class SimpleJob1 : IJob
{
public virtual void Execute(IJobExecutionContext context)
{

JobKey jobKey = context.JobDetail.Key;
//log.InfoFormat("SimpleJob1 says: {0} executing at {1}", jobKey, DateTime.Now.ToString("r"));
Console.WriteLine("作业1: {0} executing at {1}", jobKey, DateTime.Now.ToString("r"));
System.Threading.Thread.Sleep(1000);

}
}
public class SimpleJob2 : IJob
{

public virtual void Execute(IJobExecutionContext context)
{

// This job simply prints out its job name and the
// date and time that it is running
JobKey jobKey = context.JobDetail.Key;
Console.WriteLine("作业2: {0} executing at {1}", jobKey, System.DateTime.Now.ToString("r"));
System.Threading.Thread.Sleep(2000);
}
}
public class SimpleJob3 : IJob
{

public virtual void Execute(IJobExecutionContext context)
{
// This job simply prints out its job name and the
// date and time that it is running
JobKey jobKey = context.JobDetail.Key;
Console.WriteLine("作业3: {0} executing at {1}", jobKey, System.DateTime.Now.ToString("r"));

}
}
}

注意：需要引用Quartz.dll，Common.Logging.dll，Common.Logging.Core.dll
