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 contentDBwebapp.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 version1.0 encodingutf-8 ? Feature xmlnshttp://schemas.microsoft.com/sharepoint/ Idf0c813e8-68e0-4ad2-82cd-292b1b7222cd TitleModify Title Timer Job DescriptionModify Title Timer Job ScopeSite HiddenTRUE Version1.0.0.0 ReceiverAssemblyTimerJob, Version1.0.0.0, Cultureneutral, PublicKeyTokenf7436af6afb9480b ReceiverClassTimerJob.ModifyTitleInstall /Feature 添加结果 运行结果无论标题是什么都改成今天是这个月的第N天。 添加配置文件 ?xml version1.0 encodingutf-8 ? configuration appSettings add keyAAString valuehttp://localhost/ /appSettings /configuration 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/binC:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\12\BIN下就可以了 部署TimerJob脚本 echo off SET TEMPLATEc:\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 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。
