Quartz.net持久化与集群部署开发详解

序言

我前边有几篇文章有介绍过quartz的基本使用语法与类库。但是他的执行计划都是被写在本地的xml文件中。无法做集群部署,我让它看起来脆弱不堪,那是我的罪过。

但是quart.net是经过许多大项目的锤炼,走到啦今天,支持集群高可用的开发方案那是一定的,今天我就给小结下我的quartz.net开发升级过程。

Quartz.net的数据库表结构

如果支持集群与持久化,单靠本机的内存和xml来保存计算任务调度的各种状态值,可想而知,是困难的。所以支持数据库这样的解决方案,OpenSymphony组织怎么可能会给遗漏。

官方提供的各种数据库脚本:https://github.com/quartznet/quartznet/tree/master/database/tables

下面我给大家展示下quartz任务调度的MS SQLSERVER表结构

部分我们扩展开发常用到的表及字段说明

1、QRTZ_JOB_DETAILS:存储的是job的详细信息,包括:[DESCRIPTION]描述,[IS_DURABLE]是否持久化,[JOB_DATA]持久化对象等基本信息。

2、QRTZ_TRIGGERS:触发器信息,包含:job的名,组外键,[DESCRIPTION]触发器的描述等基本信息,还有[START_TIME]开始执行时间,[END_TIME]结束执行时间,[PREV_FIRE_TIME]上次执行时间,[NEXT_FIRE_TIME]下次执行时间,[TRIGGER_TYPE]触发器类型:simple和cron,[TRIGGER_STATE]执行状态:WAITING,PAUSED,ACQUIRED分别为:等待,暂停,运行中。

3、QRTZ_CRON_TRIGGERS:保存cron表达式。

4、QRTZ_SCHEDULER_STATE:存储集群中note实例信息,quartz会定时读取该表的信息判断集群中每个实例的当前状态,INSTANCE_NAME:之前配置文件中org.quartz.scheduler.instanceId配置的名字,就会写入该字段,如果设置为AUTO,quartz会根据物理机名和当前时间产生一个名字。  [LAST_CHECKIN_TIME]上次检查时间,[CHECKIN_INTERVAL]检查间隔时间。

5、QRTZ_PAUSED_TRIGGER_GRPS:暂停的任务组信息。

6、QRTZ_LOCKS,悲观锁发生的记录信息。

7、QRTZ_FIRED_TRIGGERS,正在运行的触发器信息。

8、QRTZ_SIMPLE_TRIGGERS,简单的出发器详细信息。

9、QRTZ_BLOB_TRIGGERS,触发器存为二进制大对象类型(用于Quartz用户自己触发数据库定制自己的触发器,然而JobStore不明白怎么存放实例的时候)。

.net程序配置quartz数据库参数

                //1.首先创建一个作业调度池
                var properties = new NameValueCollection();
                //存储类型
                properties["quartz.jobStore.type"] = "Quartz.Impl.AdoJobStore.JobStoreTX, Quartz";
                //表明前缀
                properties["quartz.jobStore.tablePrefix"] = "QRTZ_";
                //驱动类型
                properties["quartz.jobStore.driverDelegateType"] = "Quartz.Impl.AdoJobStore.SqlServerDelegate, Quartz";                //数据源名称
                properties["quartz.jobStore.dataSource"] = "myDS";
                //连接字符串
                properties["quartz.dataSource.myDS.connectionString"] = Config.QuartzConnStr;
                //sqlserver版本
                properties["quartz.dataSource.myDS.provider"] = "SqlServer-20";
                //最大链接数
                //properties["quartz.dataSource.myDS.maxConnections"] = "5";
                // First we must get a reference to a scheduler
                ISchedulerFactory sf = new StdSchedulerFactory(properties);
                IScheduler sched = sf.GetScheduler();

上面便是创建一个调度器,以及配置与quartz数据库的详细参数。有啦数据库后你会很兴奋,直接写t-sql操作数据库多么便捷啊,并且所有的任务调度信息都一目了然,这里我要告诉你的事,你不需要直接写sql语句,quart提供的类库就能自动对数据库进行填充,以完成对任务调度的管理操作。

quartz.net任务调度的各种操作方法

首先我要说下,我前面有一篇文章对quartz.net做个基本的操作描述,这里也只贴代码,仅供参考。

1、添加任务计划,并制定要触发的执行类

                    #region 检查是否存在
                    if (IsExistJob(m.JobGroupName, m.JobName))
                    {
                        return false;
                    }
                    #endregion
                    #region 添加任务计划
                    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 关联运行接口
                    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、移除执行计划

scheduler = GetScheduler();
var trigger = new TriggerKey(jobGroup, jobName);
scheduler.PauseTrigger(trigger);//停止触发器
scheduler.UnscheduleJob(trigger); //移除触发器
var result = scheduler.DeleteJob(JobKey.Create(jobName,jobGroup));

3、暂停指定任务计划

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

4、暂停所有的任务计划

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

5、开启指定的任务计划

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

6、开启所有的任务计划

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

7、调度启动状态,如果调度的状态没有开启,即便触发器的状态为等待执行,执行中,也是无效的。

scheduler = GetScheduler();
if (scheduler.IsStarted)
{
     return "开启";
}
else
{
     return "关闭";
}

8、是否集群 

//是否集群
//properties["quartz.jobStore.clustered"] = "false";
//properties["quartz.scheduler.instanceId"] = "AUTO";

检验下结果:

我在两台服务器上部署,设置一个任务计划,每2秒出发一次,2台机器同时跑,没有重复执行,且一台服务器down掉仍可准确无误的运行,给图。
