定时器
| 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 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 TimerExecute { public void Execute(SPWeb web, string siteUrl) { //xml配置文件信息 SPListItem it = web.Lists["timerjob"].Items[0]; SPFile file = it.File; XmlDocument doc = new XmlDocument(); doc.Load(file.OpenBinaryStream()); XmlNode root = doc.SelectSingleNode("Items"); XmlNodeList nodes = root.SelectNodes("Item"); foreach (XmlNode node in nodes) { string listUrl = siteUrl + node.SelectSingleNode("ListUrl").InnerText; SPList list = new SPSite(listUrl).OpenWeb().GetList(listUrl); SPView view = list.DefaultView; view.Scope = SPViewScope.Recursive; SPQuery query = new SPQuery(view); XmlNode nodeField = node.SelectSingleNode("Field"); XmlNode nodeBody = node.SelectSingleNode("Body"); XmlNode nodeToField=node.SelectSingleNode("ToField"); string strDay = nodeField.Attributes["day"].Value; string strField = nodeField.Attributes["name"].Value; string strStartName = nodeField.Attributes["startname"].Value; string strQuery = "<Where><Neq><FieldRef Name='Status' /><Value Type='Text' >已完成</Value></Neq></Where>"; query.Query = strQuery; SPListItemCollection items = list.GetItems(query); foreach (SPListItem item in items) { SPListItem itemRow = list.Items.GetItemById(item.ID); int diff = (Convert.ToDateTime(itemRow[strField] + string.Empty) - DateTime.Now).Days; if (strDay == "0") { if ((Convert.ToDateTime(itemRow[strField] + string.Empty) - Convert.ToDateTime(itemRow[strStartName] + string.Empty)).Days / 2 >= diff) { SendMail(itemRow, nodeBody.InnerText, nodeToField.InnerXml,root.Attributes["path"].Value); } } else if (Convert.ToInt32(strDay) >= diff) { SendMail(itemRow, nodeBody.InnerText, nodeToField.InnerXml,root.Attributes["path"].Value); } } } } public void SendMail(SPListItem item,string strBody,string toFiled,string path) { string strAssignChange = "(到期提醒)"; SPList list = item.ParentList; StringBuilder strFieldValue = new StringBuilder(); foreach (string strField in list.DefaultView.ViewFields) { if (strField != "Attachments") { strFieldValue.Append(this.GetValue(strField, list, item)); } } string strEmailBody = strBody; SPWeb web = list.ParentWeb; string strWebUrl = web.Url; string strWebTitle = web.Title; string strItemTitle = item.Title; string strItemUrl = web.Site.Url + item.ParentList.DefaultViewUrl.Substring(0, item.ParentList.DefaultViewUrl.LastIndexOf("/")) + "/dispform.aspx?ID=" + item.ID.ToString(); string strListUrl = strWebUrl + "/" + list.DefaultViewUrl.Substring(0, list.DefaultViewUrl.LastIndexOf("/")); string strListTitle = list.Title; string strUpdated = item["Modified"] + string.Empty; SPUser user = web.AllUsers.GetByID(Convert.ToInt32(item["Author"].ToString().Split(';')[0])); string strAuthor = user.Name; string strSubject = strListTitle + "-" + strItemTitle + strAssignChange; try { toFiled = toFiled.Trim(';'); string[] strUsers = toFiled.Split(';'); foreach (string field in strUsers) { if (item[field].GetType() == typeof(SPFieldUserValueCollection)) { SPFieldUserValueCollection users = item[field] as SPFieldUserValueCollection; foreach (SPFieldUserValue u in users) { Microsoft.SharePoint.Utilities.SPUtility.SendEmail(web, true, false, u.User.Email, strSubject, strEmailBody); using (System.IO.StreamWriter sw = new System.IO.StreamWriter(path, true)) { sw.WriteLine("ItemID=" + item.ID.ToString() + "User=" + u.User.LoginName + " DateTime=" + DateTime.Now.ToString()); } } } else { try { string strFieldUser = item[field] + string.Empty; if (strFieldUser != "") { SPUser fieldUser = web.AllUsers.GetByID(Convert.ToInt32(strFieldUser.Split(';')[0])); Microsoft.SharePoint.Utilities.SPUtility.SendEmail(web, true, false, fieldUser.Email, strSubject, strEmailBody); using (System.IO.StreamWriter sw = new System.IO.StreamWriter(path, true)) { sw.WriteLine("ItemID=" + item.ID.ToString() + "User="+fieldUser.LoginName+" DateTime=" + DateTime.Now.ToString()); } } } catch (Exception ex) { using (System.IO.StreamWriter sw = new System.IO.StreamWriter(path, true)) { sw.WriteLine("source=" + ex.Source + " Message=" + ex.Message); } } } } } catch(Exception ex) { using (System.IO.StreamWriter sw = new System.IO.StreamWriter(path, true)) { sw.WriteLine("source=" + ex.Source + " Message=" + ex.Message); } } } public string GetValue(string strInnerName, SPList list, SPListItem item) { SPField field = list.Fields.GetFieldByInternalName(strInnerName); string strTitle = field.Title; string strValue = string.Empty; string strEdit = string.Empty; strValue = field.GetFieldValueAsText(item[strTitle]); strEdit = " "; string str = "<tr><td class='formlabel'>{0}:</td><td class='formbody'>{1}</td><td class='altvb'>{2}</td></tr>"; str = string.Format(str, strTitle, strValue, strEdit); return str; } } } 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。 |
