定时任务 Timer JOB
最近最要在MOSS的项目任务中写一个定时提醒的功能，经过考虑采用Timer job来实现，配置信息采用XML文件
<Items>
<Item>
<ListUrl>
</ListUrl>
<Field day="0" name="截止日期" startname="创建时间">
</Field>
<Body>
</Body>
<ToField>
</ToField>
</Item>
</Items>
以下是代码:
TimerExecute类是执行发送邮件功能类

TaskListTimerJob 类继承SPJobDefinition，实现定时提醒
using System;
using System.Collections.Generic;
using System.Text;
using Microsoft.SharePoint;
using Microsoft.SharePoint.Administration;
using Microsoft.SharePoint.Utilities;
using System.Xml;
namespace MossJob
{
public class TaskListTimerJob:SPJobDefinition
{
public TaskListTimerJob()
: base()
{
}
public TaskListTimerJob(string _timername, SPWebApplication _wp)
: base(_timername, _wp, null, SPJobLockType.ContentDatabase)
{
this.Title = _timername;
}
public override void Execute(Guid targetInstanceId)
{
//base.Execute(targetInstanceId);
try
{
SPWebApplication webapp = this.Parent as SPWebApplication;
SPContentDatabase contentdb = webapp.ContentDatabases[targetInstanceId];
string siteUrl = contentdb.Sites[0].Url;
SPWeb web = contentdb.Sites[0].RootWeb;
new TimerExecute().Execute(web, siteUrl);
}
catch (Exception ex)
{
using (System.IO.StreamWriter sw = new System.IO.StreamWriter("c:\timerjob.txt", true))
{
sw.WriteLine("source=" + ex.Source + " Message=" + ex.Message);
}
}
}
}
}
把上面工程的dll 放到GAC中
Program 是控制台程序，用来部署timer job ，也可以用feature来部署，用控制台程序部署和卸载比较方便
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using MossJob;
using Microsoft.SharePoint;
using Microsoft.SharePoint.Administration;
using Microsoft.SharePoint.Utilities;
using System.Xml;
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
try
{
SPSite site = new SPSite("http://localhost/");
SPWebApplication web = site.WebApplication;
foreach (SPJobDefinition job in web.JobDefinitions)
{
string name = job.Title;
if (name == "MyCustomJobSendTaskMail")
{
job.Delete();
}
}
TaskListTimerJob newJob = new TaskListTimerJob("MyCustomJobSendTaskMail", site.WebApplication);
SPSchedule schedule = SPSchedule.FromString("daily at 20:46:00");
newJob.Schedule = schedule;
newJob.Update();
Console.WriteLine("部署成功");
}
catch (Exception ex)
{
Console.Write(ex.Message);
}
}
}
}
至此timer job 开发和部署完成，Timer job 主要是继承SPJobDefinition类，重写Execute方法即可。
