SharePoint 开发TimerJob 介绍

SharePoint 2021-09-23 11:08:07

项目需要写TimerJob，以前也大概知道原理，不过，开发过程中，还是遇到一些问题，网上看了好多博客，也有写的灰常好的，不过，自己还是想再写一下，也算是给自己一个总结，也算给大家多一个参考吧。

TimerJob项目结构，主要有两个Class，一个是用来定义TimerJob功能的，一个是用来部署开发好的TimerJob的，分别继承两个不同的类。如下图，先建一个如下结构的项目：

clip_image001

文件描述：

TimerJob定义类：ModifyTitle.cs（继承自SPJobDefinition）

TimerJob安装类：ModifyTitleInstall.cs（继承自SPFeatureReceiver）

激活TimerJob的Feature.xml

添加强命名，因为将来生成的dll是要放到GAC里面去的

添加引用：

引用Microsoft.SharePoint.dll文件，两个Class都需要添加下面命名空间

using Microsoft.SharePoint;

using Microsoft.SharePoint.Administration;

ModifyTitleInstall类

public class ModifyTitleInstall : SPFeatureReceiver

{

const string TimerJobName = "ModifyTitleTimerJob";//TimerJob的标题

//激活TimerJob的方法

public override void FeatureActivated(SPFeatureReceiverProperties properties)

{

SPSite site = properties.Feature.Parent as SPSite;

foreach (SPJobDefinition job in site.WebApplication.JobDefinitions)

{

//如果有相同的TimerJob，先删除

if (job.Title == TimerJobName)

{

job.Delete();

}

ModifyTitle modifyTitle = new ModifyTitle(TimerJobName, site.WebApplication);

SPMinuteSchedule minuteSchedule = new SPMinuteSchedule();//计时器对象

minuteSchedule.BeginSecond = 0;

minuteSchedule.EndSecond = 59;

minuteSchedule.Interval = 1;

modifyTitle.Schedule = minuteSchedule;

modifyTitle.Update();

//throw new NotImplementedException();

}

public override void FeatureDeactivating(SPFeatureReceiverProperties properties)

{

SPSite site = properties.Feature.Parent as SPSite;

foreach (SPJobDefinition job in site.WebApplication.JobDefinitions)

{

if (job.Title == TimerJobName)

{

job.Delete();

}

//throw new NotImplementedException();

}

public override void FeatureInstalled(SPFeatureReceiverProperties properties)

{

//throw new NotImplementedException();

}

public override void FeatureUninstalling(SPFeatureReceiverProperties properties)

{

//throw new NotImplementedException();

}

ModifyTitle类

public class ModifyTitle : SPJobDefinition

{

public ModifyTitle():base(){}

public ModifyTitle(string TimerName, SPWebApplication webapp) : base(TimerName, webapp, null, SPJobLockType.ContentDatabase)

{

//TimerJob的标题

this.Title = "定期修改Title的TimerJob";

}

public override void Execute(Guid targetInstanceId)

{

SPWebApplication webapp = this.Parent as SPWebApplication;

SPContentDatabase contentDB=webapp.ContentDatabases[targetInstanceId];

foreach (SPItem item in contentDB.Sites[0].RootWeb.Lists["TimerJob"].Items)

{

DateTime dt = Convert.ToDateTime(item["创建时间"].ToString());

item["标题"] = "今天是这个月的第" + dt.Day.ToString() + "天";

item.Update();

}

//base.Execute(targetInstanceId);

}

Feature.xml(Id是需要重新生成的Guid)

<?xml version="1.0" encoding="utf-8" ?>

Id="f0c813e8-68e0-4ad2-82cd-292b1b7222cd"

Title="Modify Title Timer Job"

Description="Modify Title Timer Job"

Scope="Site"

Hidden="TRUE"

Version="1.0.0.0"

ReceiverAssembly="TimerJob, Version=1.0.0.0, Culture=neutral, PublicKeyToken=f7436af6afb9480b"

ReceiverClass="TimerJob.ModifyTitleInstall">

添加结果：

clip_image003

运行结果：无论标题是什么，都改成今天是这个月的第N天。

clip_image005

添加配置文件：

<?xml version="1.0" encoding="utf-8" ?>

获取配置文件：

string AAString = ConfigurationManager.AppSettings.Get("AAString");

注：配置文件格式不对的话，可能造成Timer服务启动错误，所以，可以拷一个控制台程序debug下面的Consoleapp.exe.config文件，然后改成OWSTIMER.exe.config，然后放到12/bin（C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\12\BIN）下就可以了

部署TimerJob脚本：

@echo off

SET TEMPLATE="c:\program files\common files\microsoft shared\web server extensions\12\Template"

Echo Copying files to TEMPLATES directory

xcopy /e /y 12\TEMPLATE\* %TEMPLATE%

Echo Copying TimerJob.dll to GAC

"C:\Program Files\Microsoft SDKs\Windows\v6.0A\Bin\gacutil.exe" -if bin\TimerJob.dll

iisreset

"C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\12\bin\stsadm" -o installfeature -filename TimerJob\feature.xml -force

"C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\12\bin\stsadm" -o deactivatefeature -filename TimerJob\feature.xml -url http://localhost -force

"C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\12\bin\stsadm" -o activatefeature -filename TimerJob\feature.xml -url http://localhost -force

net stop SPTimerV3

net start SPTimerV3

PAUSE

注：新的TimerJob运行一定要重启SPTimerV3服务，在windows服务里面，如下图：
