Quartz.net持久化與集群部署開發詳解

序言

我前邊有幾篇文章有介紹過quartz的基本使用語法與類庫。但是他的執行計划都是被寫在本地的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。

Quartz.net的數據庫表結構

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(用於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)。

.net程序配置quartz數據庫參數

                //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，並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。

quartz.net任務調度的各種操作方法

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、添加任務計划，並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 添加任務計划
                    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、移除執行計划

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、暫停指定任務計划

scheduler = GetScheduler();
scheduler.PauseJob(JobKey.Create(jobName, jobGroup));

4、暫停所有的任務計划

scheduler = GetScheduler();
scheduler.PauseAll();

5、開啟指定的任務計划

 scheduler = GetScheduler();
 if (!scheduler.IsStarted)
 {
      scheduler.Start();
 }
 //scheduler.ResumeTrigger(new TriggerKey(jobName, jobGroup));              
 scheduler.ResumeJob(JobKey.Create(jobName, jobGroup));

6、開啟所有的任務計划

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：

我在兩台服務器上部署，設置一個任務計划，每2秒出發一次，2台機器同時跑，沒有重復執行，且一台服務器down掉仍可准確無誤的運行，給圖。
