Oracle与Sqlserver数据共享

需求：在一个集成平台中有一个主系统使用的是Oralce数据库，子系统使用的SqlServer 数据库，如何让子系统的数据库与主系统的人员同步呢？

思路：通过服务WebService 公开接口

        1.与主系统的数据库建立连接

        2.获取主系统中的人员信息

        3.与子系统中的人员信息对比，不存在的添加，存在不一样的跟新，多余的删除

具体代码如下：

       1.建立与Oralce 和SqlServer 数据库的连接

  //Oracle数据库连接
        private static DataSet OrcaleTransfrom(string sql)
        {
            OracleConnection conn = new OracleConnection("");
          
            conn.Open();
            var result = new DataSet();
            var dbAdapter = new OracleDataAdapter
            {
                SelectCommand =
                    new OracleCommand
                    {
                        Connection = conn,
                        CommandType = CommandType.Text,
                        CommandText = sql
                    }
            };
            dbAdapter.Fill(result);
            conn.Close();
            dbAdapter.Dispose();
            return result;
        }

        //SQL数据库连接
        private static DataSet SqlTransfrom(string sql)
        {
            SqlConnection conn = new SqlConnection("");
            conn.Open();
            var result = new DataSet();
            var dbAdapter = new SqlDataAdapter
            {
                SelectCommand =
                    new SqlCommand
                    {
                        Connection = conn,
                        CommandType = CommandType.Text,
                        CommandText = sql
                    }
            };
            dbAdapter.Fill(result);
            conn.Close();
            dbAdapter.Dispose();
            return result;
        }

 2.建立要同步数据的类：

public class Person
        {
            public DateTime? Birthday { get; set; }
            public string BloodType { get; set; }
            public string Code { get; set; }
            public string Education { get; set; }
            public DateTime? EntryDate { get; set; }
            public int Gender { get; set; }
            public string Identifier { get; set; }
            public bool IsActive { get; set; }
            public string Job { get; set; }
            public DateTime? LeftDate { get; set; }
            public string Mobile { get; set; }
            public string Name { get; set; }
            public string NativePlace { get; set; }
            public string OfficeTel { get; set; }
            public string OrgCode { get; set; }
            public string Picture { get; set; }
            public string Position { get; set; }
            public string Email { get; set; }
            public string LoginName { get; set; }
            public string Password { get; set; }
        }

 3.获取Oracle的人员信息：

        public string GetPersons()
        {
            try
            {
                string sql = "select  * from V_ASM_USER where USER_ITR=0"; 
                var PDataSet = OrcaleTransfrom(sql);//获取人员
                var perDataSet = PDataSet.Tables[0];
                List<Person> personlist = new List<Person>();
                for (var i = 0; i < perDataSet.Rows.Count; i++)
                {
                    Person persons = new Person();
                    persons.Name = perDataSet.Rows[i][1].ToString();//姓名
                    persons.Gender = perDataSet.Rows[i][4].ToString() == "1" ? 2 : 1;//性别
                    persons.OrgCode = perDataSet.Rows[i][2].ToString();//部门编码
                    persons.Code = perDataSet.Rows[i][3].ToString();//工号  
                    persons.Identifier = perDataSet.Rows[i][7].ToString();//身份证号
                    persons.Email = perDataSet.Rows[i][9].ToString(); //邮箱
                    persons.LoginName = perDataSet.Rows[i][0].ToString();//登录名
                    persons.Password = perDataSet.Rows[i][10].ToString();//密码
                    personlist.Add(persons);
                }
                XmlSerializer xmlFormat = new XmlSerializer(typeof(List<Person>));
                MemoryStream stream = new MemoryStream();
                xmlFormat.Serialize(stream, personlist);
                stream.Position = 0;
                byte[] buffer = new byte[stream.Length];
                stream.Read(buffer, 0, buffer.Length);
                stream.Flush();
                stream.Close();
                return Convert.ToBase64String(buffer);
            }
            catch (Exception ex)
            {
                throw (new Exception(ex.ToString()));
            }
        }

 更新人员：

 private void UpdatePerson(List<Person> per1, List<Person> per2, List<Person> per3)
        {
            //日志记录
            string logPath = WebConfigurationManager.AppSettings["LogFolder"];
            var logger = new Logger(logPath);
            logger.Log("--------------开始更新人员！----------------" + DateTime.Now + "------------");
            using (var _dbContext = new BaseContext())
            {
                for (var i = 0; i < per1.Count; i++)
                {
                    var OrgCode = per1[i].OrgCode;
                    var OrgID = _dbContext.Organizations.FirstOrDefault(o => o.Code == OrgCode);//新增
                    if (OrgID != null)
                    {
                        var newPerson = new Soian.Zhitai.Models.Person()
                        {
                            ID = Guid.NewGuid().ToString(),
                            Code = per1[i].Code,
                            FullName = per1[i].Name,
                            Gender = per1[i].Gender,
                            OrganizationID = OrgID.ID,//通过部门编码获取OrganizationID                            
                            CreateDate = DateTime.Now,
                            Email = per1[i].Email,
                            Identifier = per1[i].Identifier,
                            IsOffTheJob = false,
                            IsStop = false
                        };
                        var newUser = new User()
                        {
                            ID = Guid.NewGuid().ToString(),
                            Name = per1[i].LoginName,
                            Password = per1[i].Password,
                            PersonID = newPerson.ID,
                            CreateDate = DateTime.Now
                        };
                        _dbContext.Persons.Add(newPerson);
                        _dbContext.Users.Add(newUser);
                        _dbContext.SaveChanges();
                    }
                }

                for (var i = 0; i < per2.Count; i++)
                {
                    var OrgCode = per2[i].OrgCode;
                    var OrgID = _dbContext.Organizations.FirstOrDefault(o => o.Code == OrgCode);//更新
                    var Code = per2[i].Code;
                    if (OrgID != null)
                    {
                        var newUpdate = _dbContext.Persons.FirstOrDefault(o => o.Code == Code);
                        newUpdate.FullName = per2[i].Name;
                        newUpdate.Gender = per2[i].Gender;
                        newUpdate.Email = per2[i].Email;
                        newUpdate.Identifier = per2[i].Identifier;
                        newUpdate.OrganizationID = OrgID.ID;//通过部门编码获取OrganizationID
                        var newUser = _dbContext.Users.FirstOrDefault(d => d.PersonID == newUpdate.ID);//更新User
                        newUser.Name = per2[i].LoginName;
                        newUser.Password = per2[i].Password;
                        _dbContext.SaveChanges();
                    }
                }

                for (var i = 0; i < per3.Count; i++)
                {
                    var Code = per3[i].Code;
                    var newDelete = _dbContext.Persons.FirstOrDefault(o => o.Code == Code);//删除
                    if (!string.IsNullOrWhiteSpace(newDelete.ToString()))
                    {
                        newDelete.IsStop = true;
                    }

                    if (_dbContext.Users.FirstOrDefault(d => d.PersonID == newDelete.ID) != null)
                    {

                }
            }
            logger.Log("--------------更新人员结束！----------------" + DateTime.Now + "------------");
        }
 

对比人员：

  //对比人员
        private void ComparerSyncPerson(List<Person> infolist, List<Person> LocalPerson)
        {
            List<Person> localPersonListadd = new List<Person>();//新增数据
            List<Person> localPersonListupdate = new List<Person>();//更新数据
            List<Person> localPersonListdel = new List<Person>();//删除数据

            
            localPersonListadd = infolist.Where(i => !LocalPerson.Select(local => local.Code).Contains(i.Code)).ToList();
          
            localPersonListupdate = infolist.Where(i => LocalPerson.Select(local => local.Code).Contains(i.Code)).ToList();
         
            localPersonListdel = LocalPerson.Where(i => !infolist.Select(info => info.Code).Contains(i.Code)).ToList();



            UpdatePerson(localPersonListadd, localPersonListupdate, localPersonListdel);//执行更新等操作
        }

WebService接口（只有管理员有此权限）：

 [WebMethod(Description = "人员导入")]
        public void GetLocalPersonData()
        {
            var PersonStr = GetPersons();
            byte[] buffer = Convert.FromBase64String(PersonStr);
            MemoryStream stream = new MemoryStream(buffer);
            XmlSerializer xmlSearializer = new XmlSerializer(typeof(List<Person>));
            List<Person> infolist = (List<Person>)xmlSearializer.Deserialize(stream);

            for (int i = 0; i < infolist.Count(); i++)
            {
                var SyncCode = (infolist[i].OrgCode).ToString();
                infolist[i].OrgCode = GetOrganizationID(SyncCode);
            }

            using (BaseContext _dbContext = new BaseContext())
            {
                List<Person> LocalPerson = _dbContext.Persons.Where(o => true && o.FullName != "管理员").Select(o => new Person
                {
                    Name = o.FullName,
                    Gender = o.Gender,
                    OrgCode = o.OrganizationID,
                    Code = o.Code,
                    EntryDate = o.EntryDate
                }).ToList();
                ComparerSyncPerson(infolist, LocalPerson);//对比及更新
            }
        }

 调用WebService的接口。可以完成数据的跟新。不能每次都进行手工更新，所以，通过配置调度服务进行更新。

 public class RenYuanTongBuJob : IJob
    {
        public void Execute(IJobExecutionContext context)
        {

            RenYuanTongBuJobAndZhuZhiJiGouTongBu();
        }

        //实例化服务接口
        HSEDataSynchronization hs = new HSEDataSynchronization();
        public void RenYuanTongBuJobAndZhuZhiJiGouTongBu()
        { 
                //人员
                hs.GetLocalPersonData();
        }
    }

 Quartz定时任务调度的接口以前文章中有。

在Global文件中进行配置。

   private void RegisterJob()
{          
  QuartzManager<RenYuanTongBuJob>.AddJob("RenYuanTongBu", "0 0 02 ? * *");
}
