SharePoint 开发TimerJob 介绍

SharePoint 开发TimerJob 介绍

更新时间:2024-02-08 文章作者:未知 信息来源:网络 阅读次数:

SharePoint发行版本有SharePoint2003、SharePoint2007、Sharepoint 2010、SharePoint2013和SharePoint2016。SharePoint提供了功能强大的团队协作环境,使得组织能够在整个组织内部实现整合、组织、查找和提供 SharePoint站点。

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

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

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:

clip_image007

调试:TimerJob程序和WebPart等SharePoint程序,运行的进程不一样,如果需要调试,需要重新安装TimerJob,然后附加到SharePoint计时器进程(下图),进行调试!

体会:

?????? 开发完TimerJob感觉,和SharePoint的东西有一样的特点,就是代码开发比较简单,但是杂七杂八的事情很多,部署、调试起来比较麻烦,而且非常需要细心,如果其间遇到各种bug,可以建议重启下机器(我就是头天晚上,各种报错,转天就好了)。

?????? 还有就是,我的代码是SharePoint2007环境开发的,如果在2010或者更高版本,代码基本是类似的,注意目录即可,部署方式可能需要PowerShell,可以网上查一下。


Sharepoint 可以帮助企业用户轻松完成日常工作。
