NHibernate Step by Step (一) Hello,NHibernate!
NHibernate Step by Step (一) Hello,NHibernate!
好了，今天我們正式開始NHibernate的歷程，在第一次的練習中，我將盡量詳細地講解環境的配置，以後將不再詳細解釋。
基本的軟件環境如下：
1．NHibernate www.nhibernate.org 當前版本是1.0.2
2．Code Smith http://www.codesmithtools.com/
3．NHibernate模板 點擊這裏下載
當然，少不了VS2005跟SQLServer了，我這裏用的是SQLServer2005，教程用在SQLServer2000上應該沒有問題，默認情況下，我將建立並使用一個叫NHibernate的數據庫。
首先，我們先建立一個最簡單的Person表，如下完整腳本（你可以進行修改以適合自己的數據庫）：
USE [NHibernate]GOSET ANSI_NULLS ONGOSET QUOTED_IDENTIFIER ONGOSET ANSI_PADDING ONGOCREATE TABLE [dbo].[Person]( [id] [int] IDENTITY(1,1) NOT NULL, [name] [varchar](50) COLLATE Chinese_PRC_CI_AS NOT NULL, CONSTRAINT [PK_Person] PRIMARY KEY CLUSTERED ( [id] ASC)WITH (IGNORE_DUP_KEY = OFF) ON [PRIMARY]) ON [PRIMARY]GOSET ANSI_PADDING OFF僅有兩個字段，一個自動增長的id，一個name，如下：
然後將下載的nhibernate-template解壓，打開Code Smith，將模板加入”Template Explorer”，如下：
然後在其中的NHibernate.cst上點右鍵，選擇“Execute”,彈出設置窗口，在左邊的屬性窗口進行如下設置：
注意：SourceDatabase屬性在第一次選擇時需要配置一個連接字符串，配置好後Code Smith將記錄下來。 Assembly屬性代表的是生成文件的默認Assembly名，而NameSpace，顧名思義，就是使用的命名空間了，這裏我們全部使用” Test.Model”，請記住這個名字，點擊左下角的Generate，將會在指定的輸出目錄下產生兩個文件：Person.cs, Person.hbm.xml。
好了，NHibernate需要的類文件和映射文件生成完了，我們可以開始幹活了！（生成NHibernate文件均是如此步驟，以後不再贅述）
新建立一個類庫工程，爲了簡潔起見，我們命名爲Model，需要注意的是，爲了跟剛纔生成的文件對應，我們需要在Model工程的屬性頁中將起Assembly名字設爲上面的“Test.Model”,如下：
然後將剛纔生成的兩個文件Person.cs和Person.hbm.xml加入到Model工程中來，選中Person.hbm.xml文件，在屬性窗口中將其“Build Action”設置爲“Embedded Resource”(這是非常重要的一步，否則NHibernate將無法找到映射文件)，如下：
build，ok，通過。
然後建立一個控制檯工程，命名爲Console1，添加NHibernate和上面Model項目的引用，另外添加一個應用程序配置文件，如下：
<?xml version="1.0" encoding="utf-8" ?><configuration> <configSections> <section name="nhibernate" type="System.Configuration.NameValueSectionHandler, System, Version=1.0.5000.0,Culture=neutral, PublicKeyToken=b77a5c561934e089" /> </configSections> <nhibernate> <add key="hibernate.connection.provider" value="NHibernate.Connection.DriverConnectionProvider" /> <add key="hibernate.connection.driver_class" value="NHibernate.Driver.SqlClientDriver" /> <add key="hibernate.connection.connection_string" value="Server=localhost;Initial Catalog=NHibernate;Integrated Security=SSPI" /> <add key="hibernate.connection.isolation" value="ReadCommitted"/> <add key="hibernate.dialect" value="NHibernate.Dialect.MsSql2000Dialect" /> </nhibernate></configuration>
然後編寫如下代碼：
using System;using System.Collections.Generic;using System.Text;using NHibernate;using NHibernate.Cfg;using Test.Model;namespace Console1
{
class Program
{ static void Main(string[] args) { Configuration config = new Configuration().AddAssembly("Test.Model"); ISessionFactory factory = config.BuildSessionFactory(); ISession session = factory.OpenSession(); Person person = new Person(); person.Name = "Jackie Chan"; ITransaction trans = session.BeginTransaction(); try { session.Save(person); trans.Commit(); Console.WriteLine("Insert Success!");
} catch (Exception ex) { trans.Rollback(); Console.WriteLine(ex.Message); } } }
}
運行，ok，執行成功！！
我們到數據庫檢查一下，如下：
我們想要添加的記錄已經成功加入到數據庫中！！
是不是感覺有些神奇啊？好，我們開始詳細解釋。
先來看生成的兩個文件，第一個是Person.cs，如下：
using System;using System.Collections;namespace Test.Model{ Person#region Person /**//// <summary> /// Person object for NHibernate mapped table 'Person'. /// </summary> public class Person { Member Variables#region Member Variables protected int _id; protected string _name; #endregion Constructors#region Constructors public Person() { } public Person( string name ) { this._name = name; } #endregion Public Properties#region Public Properties public int Id { get {return _id;} set {_id = value;} } public string Name { get { return _name; } set { if ( value != null && value.Length > 50) throw new ArgumentOutOfRangeException("Invalid value for Name", value, value.ToString()); _name = value; } } #endregion } #endregion}
你可以發現，這完全是一個普通的poco類（Plain Old CLR Object）,僅僅是對數據庫person表的一個完全映射，不依賴於任何框架，可以用來作爲持久化類，你可以在任何地方使用而不用擔心依賴於某些神祕的運行時東西。
另外，NHibernate需要知道怎樣去加載（load）和存儲（store）持久化類的對象。這正是NHibernate映射文件發揮作用的地方。映射文件告訴NHibernate它應該訪問數據庫(database)裏面的哪個表（table）及應該使用表裏面的哪些字段（column）,這就是我們今天要講的重點了，Person.hbm.xml，如下：
<?xml version="1.0" encoding="utf-8" ?><hibernate-mapping xmlns="urn:nhibernate-mapping-2.0"> <class name="Test.Model.Person, Test.Model" table="Person"> <id name="Id" type="Int32" unsaved-value="0"> <column name="id" sql-type="int" not-null="true" unique="true" index="PK_Person"/> <generator class="native" /> </id> <property name="Name" type="String"> <column name="name" length="50" sql-type="varchar" not-null="true"/> </property> </class></hibernate-mapping>
不用說，最頂層的hibernate-mapping節點是NHibernate用來進行映射的根了，其中，包含一個class節點，裏面的name屬性對應我們的Person類，注意，需要完整的限定名；而table屬性，則顯而易見是對應數據庫中的Person表了。
我們再往裏面看，分別有兩個節點，一個是id，對應數據庫中的id，一個是屬性name，對應表中的column name和Person類中的name屬性，整個映射文件簡捷明瞭，一看即知。實際上這是由代碼產生工具產生的映射文件，裏面很多東西我們其實可以省略，如下寫法：
<property name=”Name” column=”name” />
NHibernate將自動去匹配數據庫中的列而不需要我們來設置。
下面，我們來看一下應用程序配置文件中都記錄了那些東西，如下：
hibernate.connection.provider_class
定製IConnectionProvider的類型.
例如：full.classname.of.ConnectionProvider （如果提供者創建在NHibernate中）, 或者 full.classname.of.ConnectionProvider, assembly （如果使用一個自定義的IConnectionProvider接口的實現，它不屬於NHibernate）。
hibernate.connection.driver_class
定製IDriver的類型.
full.classname.of.Driver （如果驅動類創建在NHibernate中）, 或者 full.classname.of.Driver, assembly （如果使用一個自定義IDriver接口的實現，它不屬於NHibernate）。
hibernate.connection.connection_string
用來獲得連接的連接字符串.
hibernate.connection.isolation
設置事務隔離級別. 請檢查 System.Data.IsolationLevel 來得到取值的具體意義並且查看數據庫文檔以確保級別是被支持的。
例如： Chaos, ReadCommitted, ReadUncommitted, RepeatableRead, Serializable, Unspecified
hibernate.dialect
NHibernate方言（Dialect）的類名 - 可以讓NHibernate使用某些特定的數據庫平臺的特性
例如： full.classname.of.Dialect（如果方言創建在NHibernate中）, 或者full.classname.of.Dialect, assembly （如果使用一個自定義的方言的實現，它不屬於NHibernate）。
接着，我們開始解釋代碼的執行，如下：
Configuration config = new Configuration().AddAssembly("Test.Model");//通過配置對象來產生一個SessionFactory對象，這是一個Session工廠，//那麼Session是用來幹什麼的呢？一個Session就是由NHibernate封裝//的工作單元，我們可以近似地認爲它起到ADO.Net中Connection的作用。ISessionFactory factory = config.BuildSessionFactory();ISession session = factory.OpenSession();Person person = new Person();person.Name = "Jackie Chan";//這裏，開啓一個由NHibernate封裝的事務，當然，在這裏最終代表//的還是一個真實的數據庫事務，但是我們已經不需要再區分到底是//一個SqlTransaction還是一個ODBCTransaction了ITransaction trans = session.BeginTransaction();try{ //保存，提交，就這麼簡單！！ session.Save(person); trans.Commit(); Console.WriteLine("Insert Success!");}catch (Exception ex){ trans.Rollback(); Console.WriteLine(ex.Message);}
現在有了一個基本的概念了吧？？
好了，第一篇就講這麼多，我們下次再接着練習。
Step by Step，顧名思義，是一步一步來的意思，整個教程我將貫徹這一理念，待此係列結束後，我們再就某些高級話題進行深入。
任何建議或者批評，請e：[email protected]

實際上，在我上面的演示代碼裏其實也應該添加System.Collections引用的，因爲目前nhibernate官方還不支持generic，一個query對象返回的還是一個普通的IList。

感謝abluedog，找了很久都沒找到這樣的入門級教程，其他教程像參考手冊，有點摸不着頭腦！
數據庫腳本在MS SQL 2000下沒有直接運行成功，手動建立後導出腳本如下：
CREATE TABLE [dbo].[Person] (
[id] [int] IDENTITY (1, 1) NOT NULL ,
[name] [varchar] (50) COLLATE Chinese_PRC_CI_AS NULL
) ON [PRIMARY]
GO
ALTER TABLE [dbo].[Person] WITH NOCHECK ADD
CONSTRAINT [PK_Person] PRIMARY KEY CLUSTERED
(
[id]
) ON [PRIMARY]
GO
好像少了ALTER TABLE [dbo].[Person] WITH NOCHECK ADD，不知道是不是2000和2005版本上的差別？
還要感謝福娃指出.net1.1上代碼需要修改的地方！
繼續期待後面的教程！ 回覆 引用 查看

ISession s = f.OpenSession();
ITransaction t = s.BeginTransaction();

我照着你的方法去做，卻發現老是報錯，後經調查我發現原來是，竟然是nhibernate中有一個錯誤，那就是它要對屬性成成的方法要判斷它是否是Virtual如下:
在ProxyTypeValidator頁下的CheckEveryPublicMemberIsVirtual方法它要檢查所有公共的方法是否是Virtual,而檢查屬性則報錯，請問這裏爲什麼要進行這樣檢查，有什麼好的解決方法嗎？ 回覆 引用 查看

Realize that true happiness lies within you. Waste no time and effort searching for peace and contentment and joy in the world outside. Remember that there is no happiness in having or in getting, but only in giving. Reach out. Share. Smile. Hug. Happiness is a perfume you cannot pour on others without getting a few drops on yourself. 回覆 引用 查看

請問一個問題。我按照你的本個教程，建立控制檯工程的時候報錯了。就是“然後建立一個控制檯工程，命名爲Console1，添加NHibernate和上面Model項目的引用，另外添加一個應用程序配置文件”這裏的時候vs2005報錯了。
我在這個控制檯工程中，新建了一個應用程序配置文件（application configuration file）。我拷貝了你的配置文件的內容的時候：
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configSections>
<section name="nhibernate" type="System.Configuration.NameValueSectionHandler, System,
Version=1.0.5000.0,Culture=neutral, PublicKeyToken=b77a5c561934e089" />
</configSections>
</configuration>
添加到上面的代碼，沒有問題。
就是添加：
<nhibernate>
<add key="hibernate.connection.provider" value="NHibernate.Connection.DriverConnectionProvider" />
<add key="hibernate.connection.driver_class" value="NHibernate.Driver.SqlClientDriver" />
<add key="hibernate.connection.connection_string" value="Server=localhost;Initial Catalog=NHibernate;Integrated Security=SSPI" />
<add key="hibernate.connection.isolation" value="ReadCommitted"/>
<add key="hibernate.dialect" value="NHibernate.Dialect.MsSql2000Dialect" />
</nhibernate>
的時候vs2005報錯：
Message 1 Could not find schema information for the element 'nhibernate'. D:/NHibernate_projects/Model/Console1/Console1/App.config 7 4 Console1
Message 2 Could not find schema information for the element 'add'. D:/NHibernate_projects/Model/Console1/Console1/App.config 8 6 Console1
Message 3 Could not find schema information for the attribute 'key'. D:/NHibernate_projects/Model/Console1/Console1/App.config 8 10 Console1
一共有１６個錯誤。

public virtual string Name
{
