步步为营 SharePoint 开发学习笔记系列 七、SharePoint Timer Job 开发

sharpds77

　　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>
/// <param name="service">The service.</param>
/// <param name="server">The server.</param>
/// <param name="targetType">Type of the target.</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。
　　下面我们来讲解TaskLoggerFeature的代码设计,首先引用:

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

　　而后代码如下：

    public class TaskLoggerFeature : SPFeatureReceiver
{
#region [Override Methods]
/// <summary>
/// Active the feature
/// </summary>
/// <param name="properties"></param>
public override void FeatureActivated(SPFeatureReceiverProperties properties)
{
SPSite site = properties.Feature.Parent as SPSite;
SPSite currentSite = null;
try
{
SPSecurity.RunWithElevatedPrivileges(delegate
{
currentSite = new SPSite(site.Url);
});
this.InstallTaskLoggerJob(currentSite);
}
catch (Exception ex)
{
LogHepler.InitConfigListSiteUrl(site.Url);
LogHepler.LogToShrepointList(ex);
}
finally
{
if (currentSite != null)
{
currentSite.Dispose();
}
}
}
/// <summary>
/// Deactive the feature
/// </summary>
/// <param name="properties"></param>
public override void FeatureDeactivating(SPFeatureReceiverProperties properties)
{
SPSite site = properties.Feature.Parent as SPSite;
SPSite currentSite = null;
try
{
SPSecurity.RunWithElevatedPrivileges(delegate
{
currentSite = new SPSite(site.Url);
});
SPWebApplication webApp = currentSite.WebApplication;
this.UninstallTaskLoggerJob(webApp);
}
catch (Exception ex)
{
LogHepler.InitConfigListSiteUrl(site.Url);
LogHepler.LogToShrepointList(ex);
}
finally
{
if (currentSite != null)
{
currentSite.Dispose();
}
}
}
/// <summary>

/// </summary>
/// <param name="properties"></param>
public override void FeatureInstalled(SPFeatureReceiverProperties properties)
{
}
/// <summary>

public override void FeatureUninstalling(SPFeatureReceiverProperties properties)
{
}
#endregion

private void InstallTaskLoggerJob(SPSite site)
{
TaskLoggerJob jobDef = new TaskLoggerJob("TaskLoggerJob", site.WebApplication);
jobDef.Title = "TaskLoggerJob";
jobDef.Properties.Add("SiteUrl", site.Url);
this.InstallDayJob(jobDef, site, 23);
//this.InstallHourJob(jobDef, site, 2);
//this.InstallMinuteJob(jobDef, site, 10, 10);
}

foreach (SPJobDefinition jobDef in jobColl)
{
if (!String.IsNullOrEmpty(jobDef.Title) && jobDef.Title.StartsWith("TaskLoggerJob"))
{
idsToRemove.Add(jobDef.Id);
}
}
if (idsToRemove.Count > 0)
{
foreach (Guid gd in idsToRemove)
{
jobColl.Remove(gd);

foreach (SPJobDefinition job in jobCollection)
{
if (job.Title.Equals(Title))
{
result = job;
break;
}
}
}
return result;
}
#endregion
}

　　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:

        /// <summary>
/// Active the feature
/// </summary>
/// <param name="properties"></param>
public override void FeatureActivated(SPFeatureReceiverProperties properties)
{
SPSite site = properties.Feature.Parent as SPSite;
SPSite currentSite = null;
try
{
SPSecurity.RunWithElevatedPrivileges(delegate
{
currentSite = new SPSite(site.Url);
});
this.InstallTaskLoggerJob(currentSite);
}
catch (Exception ex)
{
LogHepler.InitConfigListSiteUrl(site.Url);
LogHepler.LogToShrepointList(ex);
}
finally
{
if (currentSite != null)
{
currentSite.Dispose();
}
}
}


卸载这个Job的方法如下：
        /// <summary>
/// Deactive the feature
/// </summary>
/// <param name="properties"></param>
public override void FeatureDeactivating(SPFeatureReceiverProperties properties)
{
SPSite site = properties.Feature.Parent as SPSite;
SPSite currentSite = null;
try
{
SPSecurity.RunWithElevatedPrivileges(delegate
{
currentSite = new SPSite(site.Url);
});
SPWebApplication webApp = currentSite.WebApplication;
this.UninstallTaskLoggerJob(webApp);
}
catch (Exception ex)
{
LogHepler.InitConfigListSiteUrl(site.Url);
LogHepler.LogToShrepointList(ex);
}
finally
{
if (currentSite != null)
{
currentSite.Dispose();
}
}
}
　　
　　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。

        /// <summary>
/// Method to install the job that will execute by hour
/// </summary>
/// <param name="jobDef">The JobDefinition to apply</param>
/// <param name="web">The SPWeb that will execute the job</param>
/// <param name="minute">The minute to start the job in that hour</param>
private void InstallDayJob(SPJobDefinition jobDef, SPSite site, int hour)
{
try
{
SPWebApplication webApp = site.WebApplication;
SPJobDefinitionCollection jboColl = webApp.JobDefinitions;
SPDailySchedule daySched = new SPDailySchedule();
daySched.BeginHour = hour;
daySched.BeginMinute = 0;
daySched.BeginSecond = 0;
daySched.EndHour = hour;
daySched.EndMinute = 0;
daySched.EndSecond = 0;
jobDef.Schedule = daySched;
SPJobDefinition oldJob = this.GetJobDeffinition(jobDef.Title, jboColl);
if (oldJob != null)
{
jboColl.Remove(oldJob.Id);
webApp.Update();
}
jboColl.Add(jobDef);
webApp.Update();
}
catch (Exception ex)
{
LogHepler.LogToShrepointList(ex);
}
}
/// <summary>
/// Method to install the job that will execute by hour
/// </summary>
/// <param name="jobDef">The JobDefinition to apply</param>
/// <param name="web">The SPWeb that will execute the job</param>
/// <param name="minute">The minute to start the job in that hour</param>
private void InstallHourJob(SPJobDefinition jobDef, SPSite site, int minute)
{
try
{
SPWebApplication webApp = site.WebApplication;
SPJobDefinitionCollection jboColl = webApp.JobDefinitions;
SPHourlySchedule hourSched = new SPHourlySchedule();
hourSched.BeginMinute = minute;
jobDef.Schedule = hourSched;
SPJobDefinition oldJob = this.GetJobDeffinition(jobDef.Title, jboColl);
if (oldJob != null)
{
jboColl.Remove(oldJob.Id);
webApp.Update();
}
jboColl.Add(jobDef);
webApp.Update();
}
catch (Exception ex)
{
LogHepler.LogToShrepointList(ex);
}
}
/// <summary>
/// Method to install the job that will execute by minute
/// </summary>
/// <param name="jobDef">The JobDefinition to apply</param>
/// <param name="web">The SPWeb that will execute the job</param>
/// <param name="secound">The seconds to start the job in that minute</param>
private void InstallMinuteJob(SPJobDefinition jobDef, SPSite site, int second, int interval)
{
try
{
SPWebApplication webApp = site.WebApplication;
SPJobDefinitionCollection jboColl = webApp.JobDefinitions;
SPMinuteSchedule minSched = new SPMinuteSchedule();
minSched.Interval = interval;
minSched.BeginSecond = second;
jobDef.Schedule = minSched;
SPJobDefinition oldJob = this.GetJobDeffinition(jobDef.Title, jboColl);
if (oldJob != null)
{
jboColl.Remove(oldJob.Id);
webApp.Update();
}
jboColl.Add(jobDef);
webApp.Update();
}
catch (Exception ex)
{
LogHepler.LogToShrepointList(ex);
}
}
　　
　　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

　　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 .
