Git.Framework 框架隨手記--ORM專案工程

賀臣發表於2014-05-05

  前面已經簡單介紹過了該框架(不一定是框架),本文開始重點記錄其使用過程。可能記錄的內容不是太詳盡,框架也可能非常爛,但是裡面的程式碼句句是實戰專案所得。本文非教唆之類的文章,也非批判之類的文章,更不是炫技之類的文章,只是工作的記錄和總結,希望能夠給大家一些啟迪,忘諸位勿噴!

 

  一. 組建專案需要的幾個部分

    .NET中最為經典的三層結構,眾所周知,無人不曉. 在Git.Framework框架中我們也遵循最基本的這種結構,ORM部分我們劃分為如下: 資料實體層,資料訪問介面層,資料訪問層,[層序主入口載入相應的配置]。 在上一篇我們講到了最基本的配置。這幾個層次結構都要遵循一定的規則.

    專案結構截圖:

     

    以上是用這個框架開發的一套倉庫管理系統: 其中Git.Storage.Entity是對應的是實體資料層, Git.Storage.IDataAccess 是資料訪問介面層,Git.Storage.DataAccess資料訪問層。當然我們也可以將這些內容合併到一個類庫中,但是一般不建議這麼做。 而Git.Storage.Web 則是專案的檢視層,也就是程式的主入口。

 

  二. 實體類的對映

    既然做物件關係對映,那麼我們就要將Entity和資料庫的相關資訊關聯起來。先看看一個實體類的程式碼

實體類程式碼

    

[TableAttribute(DbName = "JooShowGit", Name = "InStorage", PrimaryKeyName = "ID", IsInternal = false)]

    這個用於實體的描述特性,用於關聯資料庫中的表,這裡簡單將各個屬性描述一下:

    [DBName] 用於適配資料庫連線配置檔案中的name屬性,可以結合下面的xml配置對比看

<?xml version="1.0" encoding="utf-8" ?>
<databaseList>
  <database name="JooShowGit">
    <connectionString>Server=127.0.0.1;database=JooShowGit;user id=sa;Password=000000</connectionString>
  </database>
</databaseList>

    [Name] 用於關聯到這個連線的資料庫中對應的哪一張表,比如這個配置就是對應資料庫中的InStorage表

    [PrimaryKeyName] 指定這張表的主鍵欄位名, 這裡我們一般用主鍵自增列,目前尚不支援聯合組建

    [IsInternal] 這個暫無特別意義,作為保留屬性

[DataMapping(ColumnName = "ID", DbType = DbType.Int32,Length=4,CanNull=false,DefaultValue=null,PrimaryKey=true,AutoIncrement=true,IsMap=true)]

    [ColumnName] 對應資料庫中的欄位名

    [DbType] 對應的資料型別

    [Length]對應的資料儲存為長度

    [CanNull] 這個欄位是否允許為空

    [DefaultValue]預設值

    [PrimaryKey]是否主鍵

    [AutoIncrement]是否自增

    [IsMap] 是否對映欄位 【注意這個標識屬性,如果這個欄位有對應的資料庫對映欄位則為true,否則為false。 因為在某些情況下實體類還有擴充套件欄位,但是這些欄位在資料庫並沒有】

public partial class InStorageEntity:BaseEntity

    實體類需要整合BaseEntity類,BaseEntity中定義了很多方法,用於便捷操作輔助操作。

  

  三. 資料訪問介面

    文章開頭已經說過了,使用該框架需要遵循一定的規則模式,資料訪問介面也是如此,先看看下面一段程式碼:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Data;
using Git.Framework.ORM;
using Git.Storage.Entity.InStorage;

namespace Git.Storage.IDataAccess.InStorage
{
    public partial interface IInStorage : IDbHelper<InStorageEntity>
    {
    }
}
IInStorage 介面定義

    這段程式碼定義了一個介面IInStorage,但是這個介面繼承了泛型介面IDbHelper<T>。 而IDbHelper<T>是框架中定義的一個介面,這個介面封裝了對資料庫操作的一些方法。

public interface IDbHelper<T> : IDisposable where T : Git.Framework.ORM.BaseEntity
    {
        int Add(List<T> list);
        int Add(T entity);
        int Add(List<T> list, bool isOpenTrans);
        int Add(T entity, bool isOpenTrans);
        int Delete(IEnumerable<int> ids);
        int Delete(int id);
        int Delete(object value);
        int Delete(T entity);
        int Delete(IEnumerable<int> ids, bool isOpenTrans);
        int Delete(int id, bool isOpenTrans);
        int Delete(object value, bool isOpenTrans);
        int Delete(T entity, bool isOpenTrans);
        int DeleteBatch(IEnumerable<T> list, bool isOpenTrans);
        int GetCount();
        int GetCount(bool isOpenTrans);
        int GetCount(T entity);
        int GetCount(T entity, bool isOpenTrans);
        List<T> GetList();
        List<T> GetList(bool isOpenTrans);
        List<T> GetList(T entity);

IDbHelper

    檢視上面的類,裡面定義了非常多的方法,包含了增刪改查所用的常用方法,使用該介面中的方法可以滿足大部分的增刪改查操作,當然特別複雜的SQL操作是不能完成的,我們還提供了其他的方式來操作,後面詳細說明。

    因為IInStorage 介面繼承了IDbHelper<T>介面,那IInStorage也用於了IDbHelper中的所有屬性和方法,但是這裡是一個泛型介面,通過制定操作類我們可以約束該介面操作哪個類,而不會沒有方向性的去操作其他無關類。從介面IDbHelper<T>中我們可以看到T 是使用了泛型約束的,T必須繼承BaseEntity 類。剛好和上面的實體對映類吻合。

 

  四. 資料訪問

    資料訪問層要實現資料訪問介面,先看看一下程式碼:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Data;
using Git.Framework.ORM;
using Git.Framework.MsSql;
using Git.Storage.Entity.InStorage;
using Git.Storage.IDataAccess.InStorage;

namespace Git.Storage.DataAccess.InStorage
{
    public partial class InStorageDataAccess : DbHelper<InStorageEntity>, IInStorage
    {
        public InStorageDataAccess()
        {
        }

    }
}
InStorageDataAccess

    以上程式碼也沒有什麼特別的地方,只是這個類繼承了一個實體類,並且實現了一個介面

public partial class InStorageDataAccess : DbHelper<InStorageEntity>, IInStorage

    DbHelper<InStorageEntity> 這個是框架中自帶的一個泛型類,該泛型類實現了泛型介面IDbHelper<T> , 上面這個類還實現了介面IInStorage介面,所以這個類也必須實現

IInStorage中的擴充套件的方法。

 

  五. 如何使用

    怎麼使用以上框架運算元據庫,其實非常簡單了,使用介面new 一個子類物件即可,沒有其他特殊的方式,也沒有使用IOC注入等。看看下面的程式碼

public IInStorage InStorage { get { return new InStorageDataAccess(); } }

--------------------------------------------------------------------------------
public override string Create(InStorageEntity entity, List<InStorDetailEntity> list)
        {
            using (TransactionScope ts = new TransactionScope())
            {
                int line = 0;
                entity.OrderNum = entity.OrderNum.IsEmpty() ? (new TNumProivder()).GetSwiftNum(typeof(InStorageEntity), 5) : entity.OrderNum;
                entity.IncludeAll();
                if (!list.IsNullOrEmpty())
                {
                    list.ForEach(a =>
                    {
                        a.IncludeAll();
                        a.OrderNum = entity.OrderNum;
                    });
                    entity.Num = list.Sum(q => q.Num);
                    entity.Amount = list.Sum(a => a.Amount);
                    line = this.InStorage.Add(entity);
                    line += this.InStorDetail.Add(list);
                }
                ts.Complete();
                return line > 0 ? EnumHelper.GetEnumDesc<EReturnStatus>(EReturnStatus.Success) : string.Empty;
            }
        }
測試程式碼

    上面的程式碼用於建立一個單據的,單據在系統中一個是一個抽象類,這裡不過多的累述。

    entity.IncludeAll();  注意到這個語句,在插入資料的時候要呼叫這個方法,這個方法用於自定哪些欄位插入到資料庫,後面詳述具體過程。

    this.InStorage.Add(entity); 最終我們只需要將呼叫這個方法Add 就可以將實體InStorageEntity的例項資料插入到對應的資料庫表InStorage中。

 

  六. 總結

    要使用此框架可以整理為一下結果步驟:

    (1)新建工程並且引入框架中提供的類庫

    (2)在主程式中配置相應的配置檔案,用於連線資料庫[配置文章必須遵循規則以及存放路徑]

    (3)編寫或者生產實體對映類,資料訪問介面,資料訪問類三部分,資料訪問介面有時候也可以省略

    (4)建立介面例項呼叫介面中提供的方法  

    總的來說該操作相對於ADO.NET還是比較方便的,但是和目前一些較為流行的框架比如Linq to SQL,Entity Framework 等比較還是比較有差距,所以還需要不斷的努力完善。

 

    目前公司一直在使用這個框架,效果還不錯。如果你要說這些東西什麼什麼框架都可以實現,為什麼要自己搞一套,我只能說這是積累!
