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。
