我前邊有幾篇文章有介紹過quartz的基本使用語法與類庫。但是他的執行計劃都是被寫在本地的xml文件中。無法做集群部署，我讓它看起來脆弱不堪，那是我的罪過。
但是quart.net是經過許多大項目的錘煉，走到啦今天，支持集群高可用的開發方案那是一定的，今天我就給小結下我的quartz.net開發升級過程。
如果支持集群與持久化，單靠本機的內存和xml來保存計算任務調度的各種狀態值，可想而知，是困難的。所以支持數據庫這樣的解決方案，OpenSymphony組織怎么可能會給遺漏。
官方提供的各種數據庫腳本：https://github.com/quartznet/quartznet/tree/master/database/tables
下面我給大家展示下quartz任務調度的MS SQLSERVER表結構

部分我們擴展開發常用到的表及字段說明
1、QRTZ_JOB_DETAILS：存儲的是job的詳細信息，包括：[DESCRIPTION]描述，[IS_DURABLE]是否持久化，[JOB_DATA]持久化對象等基本信息。
2、QRTZ_TRIGGERS：觸發器信息,包含：job的名，組外鍵，[DESCRIPTION]觸發器的描述等基本信息，還有[START_TIME]開始執行時間，[END_TIME]結束執行時間，[PREV_FIRE_TIME]上次執行時間，[NEXT_FIRE_TIME]下次執行時間，[TRIGGER_TYPE]觸發器類型：simple和cron，[TRIGGER_STATE]執行狀態：WAITING，PAUSED，ACQUIRED分別為：等待，暫停，運行中。
3、QRTZ_CRON_TRIGGERS：保存cron表達式。
4、QRTZ_SCHEDULER_STATE：存儲集群中note實例信息，quartz會定時讀取該表的信息判斷集群中每個實例的當前狀態，INSTANCE_NAME:之前配置文件中org.quartz.scheduler.instanceId配置的名字，就會寫入該字段，如果設置為AUTO,quartz會根據物理機名和當前時間產生一個名字。 [LAST_CHECKIN_TIME]上次檢查時間，[CHECKIN_INTERVAL]檢查間隔時間。
5、QRTZ_PAUSED_TRIGGER_GRPS：暫停的任務組信息。
6、QRTZ_LOCKS，悲觀鎖發生的記錄信息。
7、QRTZ_FIRED_TRIGGERS，正在運行的觸發器信息。
8、QRTZ_SIMPLE_TRIGGERS，簡單的出發器詳細信息。
9、QRTZ_BLOB_TRIGGERS,觸發器存為二進制大對象類型(用于Quartz用戶自己觸發數據庫定制自己的觸發器，然而JobStore不明白怎么存放實例的時候)。
//1.首先創建一個作業調度池 var properties = new NameValueCollection(); //存儲類型 properties["quartz.jobStore.type"] = "Quartz.Impl.AdoJobStore.JobStoreTX, Quartz"; //表明前綴 properties["quartz.jobStore.tablePrefix"] = "QRTZ_"; //驅動類型 properties["quartz.jobStore.driverDelegateType"] = "Quartz.Impl.AdoJobStore.SqlServerDelegate, Quartz"; //數據源名稱 properties["quartz.jobStore.dataSource"] = "myDS"; //連接字符串 properties["quartz.dataSource.myDS.connectionString"] = Config.QuartzConnStr; //sqlserver版本 properties["quartz.dataSource.myDS.provider"] = "SqlServer-20"; //最大鏈接數 //properties["quartz.dataSource.myDS.maxConnections"] = "5"; // First we must get a reference to a scheduler ISchedulerFactory sf = new StdSchedulerFactory(properties); IScheduler sched = sf.GetScheduler();
上面便是創建一個調度器，以及配置與quartz數據庫的詳細參數。有啦數據庫后你會很興奮，直接寫t-sql操作數據庫多么便捷啊，并且所有的任務調度信息都一目了然，這里我要告訴你的事，你不需要直接寫sql語句，quart提供的類庫就能自動對數據庫進行填充，以完成對任務調度的管理操作。
首先我要說下，我前面有一篇文章對quartz.net做個基本的操作描述，這里也只貼代碼，僅供參考。
1、添加任務計劃，并制定要觸發的執行類
#region 檢查是否存在 if (IsExistJob(m.JobGroupName, m.JobName)) { return false; } #endregion #region 添加任務計劃 if (m.StarTime == null) { m.StarTime = DateTime.Now; } DateTimeOffset starRunTime = DateBuilder.NextGivenSecondDate(m.StarTime, 1); if (m.EndTime == null) { m.EndTime = DateTime.MaxValue.AddDays(-1); } DateTimeOffset endRunTime = DateBuilder.NextGivenSecondDate(m.EndTime, 1); scheduler = GetScheduler(); IJobDetail job = JobBuilder.Create<QuartzFunction>() .WithIdentity(m.JobName, m.JobGroupName) .WithDescription(m.JobDescribe) .Build(); ICronTrigger trigger = (ICronTrigger)TriggerBuilder.Create() .StartAt(starRunTime) .EndAt(endRunTime) .WithIdentity(m.JobName, m.JobGroupName) .WithCronSchedule(m.CronStr) .WithDescription(m.JobDescribe) .Build(); scheduler.ScheduleJob(job, trigger); scheduler.Start(); #endregion #region 關聯運行接口 var api = new A_RunJobTriggerEntity(); api.ApiCode = m.ApiCode; api.ApiType = m.ApiType; api.ApiUrl = m.ApiUrl; api.AppID = m.AppID; api.CreateTime = DateTime.Now; api.JobDescribe = m.JobDescribe; api.ServiceCode = m.ServiceCode; api.Token = m.Token; api.TriggerGroup = m.JobGroupName; api.TriggerName = m.JobName; new ARunJobRelationManage().Insert(api); #endregion
2、移除執行計劃
scheduler = GetScheduler();var trigger = new TriggerKey(jobGroup, jobName);scheduler.PauseTrigger(trigger);//停止觸發器scheduler.UnscheduleJob(trigger); //移除觸發器var result = scheduler.DeleteJob(JobKey.Create(jobName,jobGroup));
3、暫停指定任務計劃
scheduler = GetScheduler();scheduler.PauseJob(JobKey.Create(jobName, jobGroup));4、暫停所有的任務計劃
scheduler = GetScheduler();
scheduler.PauseAll();5、開啟指定的任務計劃
scheduler = GetScheduler(); if (!scheduler.IsStarted) { scheduler.Start(); } //scheduler.ResumeTrigger(new TriggerKey(jobName, jobGroup)); scheduler.ResumeJob(JobKey.Create(jobName, jobGroup));
6、開啟所有的任務計劃
scheduler = GetScheduler();if (!scheduler.IsStarted){ scheduler.Start();}//scheduler.ResumeTrigger(new TriggerKey(jobName, jobGroup)); scheduler.ResumeAll();
7、調度啟動狀態，如果調度的狀態沒有開啟，即便觸發器的狀態為等待執行，執行中，也是無效的。
scheduler = GetScheduler();if (scheduler.IsStarted){ return "開啟";}else{ return "關閉";}
8、是否集群
//是否集群//properties["quartz.jobStore.clustered"] = "false";//properties["quartz.scheduler.instanceId"] = "AUTO";
檢驗下結果：
我在兩臺服務器上部署，設置一個任務計劃，每2秒出發一次，2臺機器同時跑，沒有重復執行，且一臺服務器down掉仍可準確無誤的運行，給圖。
