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 = 1010 quartz.threadPool.threadPriority = Normal11 12 # job initialization plugin handles our xml reading, without it defaults are used13 quartz.plugin.xml.type = Quartz.Plugin.Xml.XMLSchedulingDataProcessorPlugin, Quartz14 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）

job 节点项说明名称类型是否必填默认值描述namestringY 任务名称groupstringN默认组名任务组名称descriptionstringN 任务描述job-typestringY 任务的类型全名称，一般实现 IJob 接口durablebooleanNfalse任务完成后是否依然保存到数据库recoverbooleanNfalse应用或服务重启之后是否忽略过期任务

- 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。

simple 节点项说明名称类型是否必填默认值描述namestringY 触发器名称groupstringN默认组名触发器名称descriptionstringN 触发器描述job-namestringY 要触发的任务的名称job-groupstringY 要触发的任务的组名称repeat-countintY0重复次数（0：不执行；-1：不限次数）repeat-intervallongY0间隔时间（单位：毫秒）start-timedateN当前时间开始时间end-timedateN 结束时间（如果不指定则一直执行直到重复次数）

2）Cron 触发器（cron 节点）根据 cron 表达式触发任务。

cron 节点项说明名称类型是否必填默认值描述namestringY 触发器名称groupstringN默认组名触发器名称descriptionstringN 触发器描述job-namestringY 要触发的任务的名称job-groupstringY 要触发的任务的组名称cronstringY 规则表达式start-timedateN当前时间开始时间end-timedateN 结束时间

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

 1 <?xml version="1.0" encoding="utf-8" ?> 2 <configuration> 3   <configSections> 4     <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" /> 5   </configSections> 6   <log4net> 7  8     <logger name="job1" additivity="false" > 9       <level value="ALL" />10       <appender-ref ref="Job1TxtAppender" />11     </logger>12 13     <appender name="Job1TxtAppender" type="log4net.Appender.RollingFileAppender">14       <file value="log/job1.txt" />15       <appendToFile value="true" />16       <param name="MaxSizeRollBackups" value="10"/>17       <param name="MaximumFileSize" value="10240KB"/>18       <param name="RollingStyle" value="Size"/>19       <param name="StaticLogFileName" value="true"/>20       <layout type="log4net.Layout.PatternLayout">21         <conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline" />22       </layout>23     </appender>24     25     <appender name="InfoFileAppender" type="log4net.Appender.RollingFileAppender">26       <file value="log/" />27       <appendToFile value="true" />28       <param name="DatePattern" value="yyyy-MM-dd'.txt'" />29       <rollingStyle value="Date" />30       <maxSizeRollBackups value="100" />31       <maximumFileSize value="1024KB" />32       <staticLogFileName value="false" />33       <Encoding value="UTF-8" />34       <filter type="log4net.Filter.LevelRangeFilter">35         <param name="LevelMin" value="INFO" />36         <param name="LevelMax" value="INFO" />37       </filter>38       <layout type="log4net.Layout.PatternLayout">39         <conversionPattern value="%date %-5level %logger  - %message%newline" />40       </layout>41     </appender>42     <appender name="ErrorFileAppender" type="log4net.Appender.RollingFileAppender">43       <file value="log/error.txt" />44       <appendToFile value="true" />45       <rollingStyle value="Size" />46       <maxSizeRollBackups value="100" />47       <maximumFileSize value="10240KB" />48       <staticLogFileName value="true" />49       <Encoding value="UTF-8" />50       <filter type="log4net.Filter.LevelRangeFilter">51         <param name="LevelMin" value="WARN" />52         <param name="LevelMax" value="FATAL" />53       </filter>54       <layout type="log4net.Layout.PatternLayout">55         <conversionPattern value="%date %-5level %logger - %message%newline" />56       </layout>57     </appender>58     <root>59       <level value="INFO" />60       <appender-ref ref="InfoFileAppender" />61       <appender-ref ref="ErrorFileAppender" />62     </root>63   </log4net>64 65 </configuration>
