正如标题所示,文章主要是围绕Quartz.Net作业调度框架话题展开的,内容出自博主学习官方Examples的学习心得与体会,文中难免会有错误之处,还请指出得以指教。

一: Calendar

前面演示过根据秒-分-时 日-月-星期等触发时机来定义一个轮询的作业调度,在实际生活中,除此之外还有根据日历来调度作业,根据日历定义触发轮询周期也是比较常用常见的功能。

在Quartz.Net中日历是由AnnualCalendar类定义的,实例化一个AnnualCalendar对象,往这个对象添加自定义的日期构成自定义的一个日历触发时机集合。

举个例子:

 

           //日历对象
            AnnualCalendar holidays = new AnnualCalendar();

            // 元旦
            DateTime NewYearDay = new DateTime(DateTime.UtcNow.Year, 1, 1);
            holidays.SetDayExcluded(NewYearDay , true);

            // 国庆节
            DateTime NationalDay= new DateTime(DateTime.UtcNow.Year, 10, 1);
            holidays.SetDayExcluded(NationalDay, true);

            // 光棍节
            DateTime SinglesDay= new DateTime(DateTime.UtcNow.Year, 11, 11);
            holidays.SetDayExcluded(SinglesDay, true);

 

有了日历对象之后,需要将日历对象附加到调度实例上,并且在触发器中使用ModifiedByCalendar("日历对象")来指定按照日历对象进行调度。

下面贴出根据日历对象指定的日期进行作业调度的代码(仅供参考):

            IJobDetail job = JobBuilder.Create<SimpleJob>()
                .WithIdentity("job1", "group1")
                .Build();

            ISimpleTrigger trigger = (ISimpleTrigger)TriggerBuilder.Create()

            sched.Start();
            log.Info("------- Waiting 30 seconds... --------------");

            log.Info("------- Shutdown Complete -----------------");

            SchedulerMetaData metaData = sched.GetMetaData();
            log.Info(string.Format("Executed {0} jobs.", metaData.NumberOfJobsExecuted));
        }
    }
}
AnnualCalendar

二:监听对象

在Quartz.Net框架中提供了一个监听器IJobListener接口,实现该接口实例化一个子类,这个子类可以监听一个作业id来触发本身的void JobWasExecuted(IJobExecutionContext inContext, JobExecutionException inException)方法:这个方法里面带了IJobExecutionContext inContext参数,inContext.Scheduler其实就是程序的调度实例,我们知道通过调度实例可以添加作业以及触发器(定制一个轮询的调度任务)并且Start()开启执行任务。

这样看来,通过实现IJobListener接口得到监听器类中的JobWasExecuted()方法里可以再次定义轮询调度作业。

比如当需要满足以下需求时可以使用监听器来实现:

=>在A任务顺利开启执行后,轮询调度B任务。(此时B任务就定义在监听器类里面)

三:插件配置

官方给出的名字叫做插件,其实我认为,这只是一种关于如何调度作业的配置。

有三种配置方式:

1.通过代码实例化NameValueCollection对象,往NameValueCollection对象以键值对形式赋值,然后在调度工厂对象中传入该NameValueCollection对象得到调度实例。

            var properties = new NameValueCollection();
            properties["quartz.plugin.triggHistory.type"] = "Quartz.Plugin.History.LoggingJobHistoryPlugin";

            properties["quartz.plugin.jobInitializer.type"] = "Quartz.Plugin.Xml.XMLSchedulingDataProcessorPlugin";//插件
            properties["quartz.plugin.jobInitializer.fileNames"] = "quartz_jobs.xml";//读取这个配置文件
            properties["quartz.plugin.jobInitializer.failOnFileNotFound"] = "true";
            properties["quartz.plugin.jobInitializer.scanInterval"] = "120";//120秒一次

            // First we must get a reference to a scheduler
            ISchedulerFactory sf = new StdSchedulerFactory(properties);
            IScheduler sched = sf.GetScheduler();
sched.Start();

通过这样方式无须再使用代码定义作业对象IJobDetail以及触发器ITrigger等,而是通过properties["quartz.plugin.jobInitializer.fileNames"]指定的xml文件来设置:

quartz_jobs.xml

 

注意点:

 1.1 quartz_jobs.xml必须设置为始终复制=>右键属性,复制到输出目录选项选择始终复制

 1.2 要将NameValueCollection对象传入StdSchedulerFactory工厂中以得到调试实例对象

       ISchedulerFactory sf = new StdSchedulerFactory(properties);

 

2.通过app.config或者web.config配置文件

通过这种方式定义调度作业的信息将会放置在app.config或web.config配置文件中,在代码中只需要得到一个无参的StdSchedulerFactory()实例对象,开启调度即可:

 

            ISchedulerFactory sf = new StdSchedulerFactory();
            IScheduler sched = sf.GetScheduler();

            // start the schedule 
            sched.Start();

App.config

在app.config中会指定调度任务信息的一个路径,比如quartz_jobs.xml文件,通过读取这个xml文件来获取调度任务。

 2.1 quartz_jobs.xml必须设置为始终复制=>右键属性,复制到输出目录选项选择始终复制

 

 

3.通过quartz.config配置文件

# You can configure your scheduler in either <quartz> configuration section
# or in quartz properties file
# Configuration section has precedence

quartz.scheduler.instanceName = ServerScheduler

# configure thread pool info
quartz.threadPool.type = Quartz.Simpl.SimpleThreadPool, Quartz
quartz.threadPool.threadCount = 10
quartz.threadPool.threadPriority = Normal

#--------------------------------*************plugin配置------------------------------------
# job initialization plugin handles our xml reading, without it defaults are used
quartz.plugin.xml.type = Quartz.Plugin.Xml.XMLSchedulingDataProcessorPlugin, Quartz
quartz.plugin.xml.fileNames = ~/quartz_jobs.xml

# export this server to remoting context
quartz.scheduler.exporter.type = Quartz.Simpl.RemotingSchedulerExporter, Quartz
quartz.scheduler.exporter.port = 555
quartz.scheduler.exporter.bindName = QuartzScheduler
quartz.scheduler.exporter.channelType = tcp
quartz.scheduler.exporter.channelName = httpQuartz
quartz.config

 

在代码中只需要得到一个无参的StdSchedulerFactory()实例对象,开启调度即可:

 

 

            ISchedulerFactory sf = new StdSchedulerFactory();
            IScheduler sched = sf.GetScheduler();

            // start the schedule 
            sched.Start();

 

 

 

 3.1 quartz_jobs.xml必须设置为始终复制=>右键属性,复制到输出目录选项选择始终复制

 3.2 quartz.config必须设置为始终复制=>右键属性,复制到输出目录选项选择始终复制
