Example of quartz.net implementation of timed task scheduling

Quartz an open source job scheduling framework, Opensymphony Open source project. Quartz.net is the Quartz C # porting version.

It has some very good features:

1: Support cluster, job grouping, job remote management.

2: Custom Fine time triggers, easy to use, job and trigger separation.

3: Database support, you can host Windows services, Website,winform and so on.

Basic concepts:

Scheduler of the job.

Ijob job interface. Inherits and implements execute, writing specific job logic for execution.

Jobbuilder generates a detailed job information (Jobdetail) based on the settings.

Triggerbuilder according to the rules, the production of the corresponding trigger

Application:

1 Create the MVC project and get the Quartz class library through NuGet

2 Package Task Factory

<summary>
Mission Factory
</summary>
<typeparam name= "T" > Work class </typeparam>
<param name= "Detailname" > Work name </param>
<param name= "Triggername" > Trigger name </param>
<param name= "Minute" > How long to start once </param>
private static void Jobsfactory<t> (String detailname, string triggername, int Minute)
where T:ijob
{
Factory 1
Ischedulerfactory factory = new Stdschedulerfactory ();
Start
IScheduler Scheduler = Factory. Getscheduler ();
Scheduler. Start ();
Describe work
Ijobdetail jobdetail = new Jobdetailimpl (detailname, NULL, typeof (T));
Trigger
Isimpletrigger trigger = new Simpletriggerimpl (Triggername,
Null
DateTime.Now,
Null
Simpletriggerimpl.repeatindefinitely,
Timespan.fromseconds (Minute));
Perform
Scheduler. Schedulejob (Jobdetail, Trigger);
}

3 Creating the work content and implementing the Ijob interface

public class Cancleorderjob:ijob
{
B_order_confrimcancelinfomanager manager = new B_order_confrimcancelinfomanager ();
public void Execute (Ijobexecutioncontext context)
{
Log4net. ILog logger = log4net. Logmanager.getlogger (System.Reflection.MethodBase.GetCurrentMethod (). DeclaringType);
var list = Manager. Getallhandleorder ();
if (list!= null)
{
foreach (var item in list)
{
if (item. Ghandletime < DateTime.Now)
{
Try
{
Manager. UpdateStatus (item.id);
}
catch (Exception e)
{
Logger. Error (E.message);
Throw
}
}
}
}
}
}

To start a task in global:

protected void Application_Start ()
{
Arearegistration.registerallareas ();
Webapiconfig.register (globalconfiguration.configuration);
Filterconfig.registerglobalfilters (globalfilters.filters);
Routeconfig.registerroutes (routetable.routes);
Bundleconfig.registerbundles (Bundletable.bundles);
Automatic cancellation of orders
Jobsfactory<cancleorderjob> ("Cancleorderdetial", "Cancleordertrigger", 1000);
Automatic Order Completion
Jobsfactory<completeorderjob> ("Completeorderdetial", "Completeordertrigger", 1000);
Load the log's configuration file
Log4net. Config.XmlConfigurator.Configure (New FileInfo (Server.MapPath ("~/web.config"));
}
Note: Log4.net log error logs are used here

Log4.net How the error log is used:

1 class libraries for application log4.net

2 Writing configuration Files

<configSections>
<!--for more information on Entity Framework configuration, visit http://go.microsoft.com/fwlink/?LinkID=237468-->
<section name= "EntityFramework" type= "System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, version=5.0.0.0, Culture=neutral, publickeytoken=b77a5c561934e089 "requirePermission=" false "/>
<section name= "log4net" type= "log4net". Config.log4netconfigurationsectionhandler, log4net "/>
</configSections>
<log4net debug= "true" >
<appender name= "Rollinglogfileappender" type= "log4net". Appender.rollingfileappender ">
<param name= "File" value= "Log//error_"/>
<param name= "Appendtofile" value= "true"/>
<param name= "maxsizerollbackups" value= "ten"/>
<param name= "Staticlogfilename" value= "false"/>
<param name= "Datepattern" value= "Yyyy-mm-dd". Log ""/>
<param name= "Rollingstyle" value= "Date"/>
<layout type= "log4net. Layout.patternlayout ">
<param name= "Conversionpattern" value= "%d-%m%n"/>
</layout>
</appender>
<root>
<level value= "DEBUG"/>
<appender-ref ref= "Rollinglogfileappender"/>
</root>

3 Read configuration file information in global

Load the log's configuration file
Log4net. Config.XmlConfigurator.Configure (New FileInfo (Server.MapPath ("~/web.config"));

4 Use:

Log4net. ILog logger = log4net. Logmanager.getlogger (System.Reflection.MethodBase.GetCurrentMethod (). DeclaringType);
Logger. Error (E.message);
