Quartz.NET Windows

Quartz.NET Windows 服务示例

想必大家在项目中处理简单的后台持续任务或者定时触发任务的时候均使用 Thread 或者 Task 来完成，但是项目中的这种需求一旦多了的话就得将任务调度引入进来了，那今天就简单的介绍一下 Quartz.NET 基于 Windows 服务宿主是怎样配置使用的。

Quartz.NET 是一个优秀的任务调度框架，移植于 Java 版的 Quartz 。

官网：http://www.quartz-scheduler.net

Github：https://github.com/quartznet/quartznet

示例环境

- .Net 4.5.2

- Quartz 2.4.1

- Common.Logging 3.3.1

- log4net 2.0.5

- Common.Logging.Log4Net1213 3.3.1

配置

1. quartz.config

这个配置文件需要放在服务运行根目录下，用于指定 quartz 的一些运行配置，比如调度名称、线程池实现组件、线程池大小、任务配置文件路径等。

 1 # You can configure your scheduler in either <quartz> configuration section
 2 # or in quartz properties file
 3 # Configuration section has precedence
 4
 5 quartz.scheduler.instanceName = QuartzNETWinServiceScheduler
 6
 7 # configure thread pool info
 8 quartz.threadPool.type = Quartz.Simpl.SimpleThreadPool, Quartz
 9 quartz.threadPool.threadCount = 10
10 quartz.threadPool.threadPriority = Normal
11
12 # job initialization plugin handles our xml reading, without it defaults are used
13 quartz.plugin.xml.type = Quartz.Plugin.Xml.XMLSchedulingDataProcessorPlugin, Quartz
14 quartz.plugin.xml.fileNames = ~/Conf/jobs.config

暂时需求需要修改的只有一处，看最后一行 quartz.plugin.xml.fileNames = ~/Conf/jobs.config 指定任务的配置文件路径。

2. 任务配置文件

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <!-- This file contains job definitions in schema version 2.0 format -->
 3 <job-scheduling-data xmlns="http://quartznet.sourceforge.net/JobSchedulingData" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.0">
 4
 5   <processing-directives>
 6     <overwrite-existing-data>true</overwrite-existing-data>
 7   </processing-directives>
 8
 9   <schedule>
10     <job>
11       <name>Job1</name>
12       <group>Jobs</group>
13       <description>任务1</description>
14       <job-type>Wlitsoft.ProjectSample.QuartzNETWinService.Job.Job1,QuartzNETWinService</job-type>
15       <durable>true</durable>
16       <recover>false</recover>
17     </job>
18     <trigger>
19       <simple>
20         <name>Job1Trigger</name>
21         <group>Jobs</group>
22         <description>每 30 秒执行一次</description>
23         <job-name>Job1</job-name>
24         <job-group>Jobs</job-group>
25         <repeat-count>-1</repeat-count>
26         <repeat-interval>30000</repeat-interval>
27       </simple>
28     </trigger>
29   </schedule>
30 </job-scheduling-data>

以下为配置文件属性：

- 任务 （job 节点）

- 触发器 （trigger 节点）

下面说下最常用的两种触发器：

1）简单触发器（simple 节点）用于触发定时轮训执行的任务。

2）Cron 触发器（cron 节点）根据 cron 表达式触发任务。

注：cron 表达式在线生成：http://cron.qqe2.com

3. 日志配置文件

1） app.config

- configSctions

1 <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />
2 <sectionGroup name="common">
3       <section name="logging" type="Common.Logging.ConfigurationSectionHandler, Common.Logging" />
4 </sectionGroup>

- commong.logging 配置

1 <common>
2     <logging>
3       <factoryAdapter type="Common.Logging.Log4Net.Log4NetLoggerFactoryAdapter, Common.Logging.Log4Net1213">
4         <arg key="configType" value="FILE-WATCH" />
5         <arg key="configFile" value="~/Conf/log4net.config" />
6         <arg key="level" value="INFO" />
7       </factoryAdapter>
8     </logging>
9 </common>

- configType : 用于指定日子配置文件类型，取值：INLINE - 在当前配置文件总；FILE-WATCH - 配置文件中。

- configFile：配置文件路径。

- level：日子输出级别。

- log4net 配置

 log4net.config
