SharePoint开发 - TimerJob简单实例讲解

博客地址 http://blog.csdn.net/foxdave

SharePoint中的TimerJob类似于Windows系统的计划任务，可以实现定时执行指定操作的功能。

本篇所述的实例为在SharePoint 2010 Foundation版本下实现SharePoint用户的同步功能。

1. 打开Visual Studio 2010，创建一个SharePoint的空解决方案，选择部署为场解决方案

2. 添加一个新类MyTimerJob，添加using引用Microsoft.SharePoint.Administration，继承SPJobDefinition类，这个便是我们自己的timerjob。然后声明两个构造函数，如下所示

using Microsoft.SharePoint.Administration;

namespace TimerJobExample
{
    public class MyTimerJob : SPJobDefinition
    {
        public MyTimerJob() : base() { }

        public MyTimerJob(string jobName, SPWebApplication webApp) : base(jobName, webApp, null, SPJobLockType.Job) { this.Title = jobName; }
    }
}

3. 接下来最重要的一步，就是我们需要写出来这个timerjob需要做什么。重写Execute方法，代码如下所示

public override void Execute(Guid targetInstanceId)
        {
            base.Execute(targetInstanceId);
            SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["SPMIPConn"].ConnectionString);
            conn.Open();
            //取站点 在webConfig部署，用户直接修改自己webConfig
            //<add key="SiteURL" value="http://spf02"/>
            string siteURL = ConfigurationManager.AppSettings["SiteURL"];
            using (SPSite st = new SPSite(siteURL))
            {
                SPWeb web = st.RootWeb;
                SPList userList = web.SiteUserInfoList; //web.Lists["用户信息列表"];
                string loginname = string.Empty;
                List<string> userIDsForDel = new List<string>();
                foreach (SPUser user in web.SiteUsers)
                {
                    if (!user.LoginName.Contains("spmipmp|"))
                    {
                        continue;
                    }
                    loginname = user.LoginName.Substring(user.LoginName.LastIndexOf('|') + 1);
                    SqlCommand cmd = conn.CreateCommand();
                    cmd.CommandText = string.Format("select a.Zhi_Gid,a.UserCode,b.zhi_gxm,c.Bu_mmch,d.Zhi_wmch from SYS_User as a left join TM_Zhigxx as b on b.Zhi_gid=a.Zhi_gid left join TD_BuM  as c on c.id=b.Bu_mid left join TM_ZhiWxx as d on d.Zhi_wxxid=b.Zhi_wid where a.Shan_Cqf='否' and a.UserCode='{0}'", loginname);
                    SqlDataReader sdr = cmd.ExecuteReader();
                    if (sdr.Read())
                    {
                        //返回或设置用户的显示名
                        user.Name = sdr["Zhi_gxm"].ToString();
                        user.Update();
                        string queryStr = "<Where><Eq><FieldRef Name='ID'/><Value Type='Number'>" + user.ID + "</Value></Eq></Where>";
                        //SPQuery类来完成对列表的查询
                        SPQuery query = new SPQuery();
                        //设置XML查询
                        query.Query = queryStr;
                        SPListItem userItem = userList.GetItems(query)[0];
                        //职务
                        userItem["JobTitle"] = sdr["Zhi_wmch"].ToString();
                        //部门
                        userItem["Department"] = sdr["Bu_mmch"].ToString();
                        userItem.Update();
                    }
                    else
                    {
                        userIDsForDel.Add(user.LoginName);
                    }
                    sdr.Close();
                }
                web.SiteUsers.RemoveCollection(userIDsForDel.ToArray());
            }
            conn.Close();
        }

这里，由于我手头的环境是基于SQL数据用户表的Form认证，戳这里，所以具体的做法是，读取到SQL用户表中的数据，然后同步到SharePoint的用户列表。

4. timerjob写完了，现在我们需要通过feature去控制这个timerjob，在feature激活的时候添加这个timerjob，并在取消激活的时候删除它，代码如下

public override void FeatureActivated(SPFeatureReceiverProperties properties)
        {
            const string MY_TASK = "SPMIP用户信息同步";//事件检查定时器
            SPSite site = properties.Feature.Parent as SPSite;
            foreach (SPJobDefinition job in site.WebApplication.JobDefinitions)
            {
                if (job.Name == MY_TASK)
                {
                    job.Delete();
                    break;
                }

            }

            Synchronization schtion = new Synchronization(MY_TASK, site.WebApplication);
            SPDailySchedule schedule = new SPMonthlySchedule();
            schedule.BeginHour = 23;
            schedule.BeginMinute = 40;
            schedule.BeginSecond = 1;
            schedule.EndHour = 23;
            schedule.EndMinute = 59;
            schedule.EndSecond = 1;
            schtion.Schedule = schedule;
            schtion.Update();
        }

        public override void FeatureDeactivating(SPFeatureReceiverProperties properties)
        {
            const string MY_TASK = "SPMIP用户信息同步";//事件检查定时器
            SPSite site = properties.Feature.Parent as SPSite;
            foreach (SPJobDefinition job in site.WebApplication.JobDefinitions)
            {
                if (job.Name == MY_TASK)
                {
                    job.Delete();
                    break;
                }
            }
        }

以上就是应用timerjob的大致过程
