概要

   项目需求要求我们每天晚上同步员工的一些信息到sharepoint 的user List ，我们决定定制开发sharepoint timer Job,Sharepoint timer Job是sharePoint的定时作业Job,需要安装、布曙到服务器上,而这里我只是介绍下Job开发的例子，以供大家学习用。

开发设计

我们需要新建两个类，TaskLoggerJob和TaskLoggerFeature,TaskLoggerJob实现这个Job具体做哪些工和，TaskLoggerFeature实现安装和卸载这个Job以及定义Job执行时间和方式。

在开发Job时需要引用如下Dll

?

using Microsoft.SharePoint;
using Microsoft.SharePoint.Utilities;
using Microsoft.SharePoint.Administration;

TaskLoggerJob设计代码如下:

public class TaskLoggerJob : SPJobDefinition
{
    #region [Fields]
 
 
 
    #endregion
 
    #region [Constructors]
 
    /// <summary>
    /// Initializes a new instance of the TaskLoggerJob class.
    /// </summary>
    public TaskLoggerJob()
        : base()
    {
    }
 
    /// <summary>
    /// Initializes a new instance of the TaskLoggerJob class.
    /// </summary>
    /// <param name="jobName">Name of the job.</param>

    public TaskLoggerJob(string jobName, SPService service, SPServer server, SPJobLockType targetType)
        : base(jobName, service, server, targetType)
    {
    }
 
    /// <summary>
    /// Initializes a new instance of the TaskLoggerJob class.
    /// </summary>
    /// <param name="jobName">Name of the job.</param>
    /// <param name="webApplication">The web application.</param>
    public TaskLoggerJob(string jobName, SPWebApplication webApplication)
        : base(jobName, webApplication, null, SPJobLockType.Job)
    {
        this.Title = "Task Logger";
    }
 
    #endregion
 
    #region [Public Methods]
 
    /// <summary>
    /// Executes the specified content db id.
    /// </summary>
    /// <param name="contentDbId">The content db id.</param>
    public override void Execute(Guid contentDbId)
    {
        try
        {
            // get a reference to the current site collection's content database
            SPWebApplication webApplication = this.Parent as SPWebApplication;
            SPContentDatabase contentDb = webApplication.ContentDatabases[contentDbId];
 
            // get a reference to the "Tasks" list in the RootWeb of the first site collection in the content database
            SPList taskList = contentDb.Sites[0].RootWeb.Lists["Tasks"];
 
            // create a new task, set the Title to the current day/time, and update the item
            SPListItem newTask = taskList.Items.Add();
            newTask["Title"] = DateTime.Now.ToString();
            newTask.Update();
 
        }
        catch (Exception ex)
        {
            LogHepler.LogToShrepointList(ex);
        }
    }
 
    #endregion
 
    #region [Private Methods]
 
 
 
    #endregion
}

在TaskLoggerFeature时我们调用这个构造方法：

?

/// <summary>
/// Initializes a new instance of the TaskLoggerJob class.
/// </summary>
/// <param name="jobName">Name of the job.</param>
/// <param name="webApplication">The web application.</param>
public TaskLoggerJob(string jobName, SPWebApplication webApplication)
    : base(jobName, webApplication, null, SPJobLockType.Job)
{
    this.Title = "Task Logger";
}

来初始化SPJobDefinition方法，Job具体要做的事性我们实现这个方法:

/// <summary>
/// Executes the specified content db id.
/// </summary>
/// <param name="contentDbId">The content db id.</param>
public override void Execute(Guid contentDbId)
{
    try
    {
        // get a reference to the current site collection's content database
        SPWebApplication webApplication = this.Parent as SPWebApplication;
        SPContentDatabase contentDb = webApplication.ContentDatabases[contentDbId];
 
        // get a reference to the "Tasks" list in the RootWeb of the first site collection in the content database
        SPList taskList = contentDb.Sites[0].RootWeb.Lists["Tasks"];
 
        // create a new task, set the Title to the current day/time, and update the item
        SPListItem newTask = taskList.Items.Add();
        newTask["Title"] = DateTime.Now.ToString();
        newTask.Update();
 
    }
    catch (Exception ex)
    {
        LogHepler.LogToShrepointList(ex);
    }
}

在这个方法里我们可以同事实现很多任务，而我们这里只是改变了它的title。

下面这个方法是激活这个Job的feature,在sharepoint里每一个Job都有一个feature来讲行实现，它会生成相应的feature的xml方件:

Job的执行时间可以按分、时、天、月、年来执行可以进行如下定义，分、时、天。概据你的需要来执行。

在完成了上面的代码设计后，我们接着就需要把Job布曙到服务器中。

要以上代码生成Windows SharePoint Solution Package (*.WSP) 来布曙。

 

步骤如下：

一、首先进入sharePoint Central administrator v3 管理页面，选择Operation下的Solution Management

image

二、检索TaskLoggerJob.wsp

如果以前安装过这个Job先要卸载，再安装。  三、执行命令   stsadm -o addsolution -filename “TaskLoggerJob.wsp”  添加Job的solution

四、执行命令 stsadm -o deactivatefeature -name TaskLoggerJob -url http://[site]/       而后再执行命令  stsadm -o execadmsvcjobs  五、执行命令 stsadm -o activatefeature -name TaskLoggerJob -url http://[site]/       而后再执行命令  stsadm -o execadmsvcjobs

总结

sharepoint timer job是用来完成系统定里执行的一此任务，是由这个进程完成的OWSTIMER.EXE .
