Nhibernate簡單 例子

1.建立web應用程式NHibernate.Demo.QuickStart和一個類庫專案NHibernate.Demo.QuickStartClassLib

2.引程式集

3..建立資料庫，資料表

USE [dbNHibernateDemo]

GO

/****** Object:  Table [dbo].[Hksj_User]    Script Date: 11/01/2013 11:35:02 ******/

SET ANSI_NULLS ON

GO

SET QUOTED_IDENTIFIER ON

GO

CREATE TABLE [dbo].[Hksj_User](

[Id] [int] IDENTITY(1,1) NOT NULL,

[SName] [nvarchar](20) NOT NULL,

[SNickName] [nvarchar](20) NULL,

[SPassWord] [nvarchar](30) NOT NULL,

[DCreateDate] [datetime] NULL,

[SCreator] [nvarchar](20) NULL,

[SEmail] [nvarchar](50) NULL,

[SPhone] [nvarchar](50) NULL,

[SIdentifyId] [nvarchar](30) NULL,

[DLastTimeLogOn] [datetime] NULL,

PRIMARY KEY CLUSTERED 

(

[Id] ASC

)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]

) ON [PRIMARY]

GO

3.設計User類。程式碼如下：

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

namespace NHibernate.Demo.QuickStartClassLib

{

    public class User

    {

        #region 屬性，欄位定義

        /// <summary>

        /// 使用者id

        /// </summary>

        public Int32 Id

        {

            get;

            set;

        }

        /// <summary>

        /// 使用者名稱，登入所用的名字

        /// </summary>

        public string Name

        {

            get;

            set;

        }

        /// <summary>

        /// 真實姓名

        /// </summary>

        public string NickName

        {

            get;

            set;

        }

        /// <summary>

        /// 密碼

        /// </summary>

        public string PassWord

        {

            get;

            set;

        }

        /// <summary>

        /// 建立日期

        /// </summary>

        public DateTime CreateTime

        {

            get;

            set;

        }

        /// <summary>

        /// 建立人

        /// </summary>

        public string Creator

        {

            get;

            set;

        }

        /// <summary>

        /// Email

        /// </summary>

        public string Email

        {

            get;

            set;

        }

        /// <summary>

        /// 聯絡電話

        /// </summary>

        public string Phone

        {

            get;

            set;

        }

        /// <summary>

        /// 身份證

        /// </summary>

        public string IdentifyId

        {

            get;

            set;

        }

        /// <summary>

        /// 最後一次登入時間

        /// </summary>

        public DateTime LastTimeLogOn

        {

            get;

            set;

        }

        #endregion

    }

}

4.建立User類的對映檔案 命名規則：User.hbm.xml  程式碼如下：

<?xml version="1.0" encoding="utf-8" ?>

  <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2">

<class name="NHibernate.Demo.QuickStartClassLib.User,NHibernate.Demo.QuickStartClassLib" table="Hksj_User" lazy="false">

<id name="Id" column="Id" type="Int32">

<generator class="native"/>

</id>

<property name="Name" column="SName" type="String" length="20" />

<property name="NickName" column="SNickName" type="String" length="20" />

<property name="PassWord" column="SPassWord" type="String" length="30" />

<property name="IdentifyId" column="SIdentifyId" type="String" length="30" />

<property name="Phone" column="SPhone" type="String" length="50" />

<property name="Email" column="SEmail" type="String" length="50" />

<property name="CreateTime" column="DCreateDate" type="DateTime" />

<property name="Creator" column="SCreator" type="String" length="20" />

<property name="LastTimeLogOn" column="DLastTimeLogOn" type="DateTime" />

</class>

</hibernate-mapping>

5.建立Nhibernate的配置檔案：Nhibernate.cfg.xml   程式碼如下： 

<?xml version="1.0" encoding="utf-8" ?>

<hibernate-configuration xmlns="urn:nhibernate-configuration-2.2" >

<session-factory>

<!-- properties -->

<property name="connection.provider">NHibernate.Connection.DriverConnectionProvider</property>

<property name="connection.driver_class">NHibernate.Driver.SqlClientDriver</property>

<property name="connection.connection_string">Data Source=DAN-PC\;Initial Catalog=dbNHibernateDemo;Integrated Security=True;</property>

<property name="dialect">NHibernate.Dialect.MySQLDialect</property>

<property name="show_sql">true </property>

<property name="use_outer_join">true</property>

<property name="query.substitutions">true 1, false 0, yes 'Y', no 'N'</property>

<!-- 代理工廠,可以試用Castle,也可以試用LinFu -->

<!-- <property name="proxyfactory.factory_class">NHibernate.ByteCode.LinFu.ProxyFactoryFactory, NHibernate.ByteCode.LinFu</property>-->

<property name="proxyfactory.factory_class">NHibernate.ByteCode.Castle.ProxyFactoryFactory, NHibernate.ByteCode.Castle</property>

<!-- mapping files 領域物件對映檔案所在程式集 -->

<mapping assembly="NHibernate.Demo.QuickStart"/>

</session-factory>

</hibernate-configuration>

解釋：

<property name="connection.connection_string">資料庫連線字串

<property name="dialect">NHibernate.Dialect.MySQLDialect</property>  資料庫型別。我用的sql server 2008R2

<mapping assembly="NHibernate.Demo.QuickStart"/>節點是web應用程式所在程式集 。

6.User.hbm.xml屬性修改

7.Nhibernate.cfg.xml屬性修改

8.到此Nhibernate所有準備工作已完成。可以寫具體的CRUD程式碼。（這裡我只增加一條資料，查詢特定使用者並在GridView上簡單展示）

後臺程式碼如下：

namespace NHibernate.Demo.QuickStart

{

    public partial class _Default : System.Web.UI.Page

    {

        public IList<User> cUsers = null;

        protected void Page_Load(object sender, EventArgs e)

        {

            NHibernate.Cfg.Configuration cfg=new NHibernate.Cfg.Configuration();//Configuration物件知道所有在.net類和後端資料庫之間的對映關係

            string path = Server.MapPath("~") + "Nhibernate.cfg.xml";

            cfg.Configure(path);//Could not compile the mapping document: NHibernate.Demo.QuickStart.User.hbm.xml   

           //Could not load type NHibernate.Dialect.MsSql2008Dialect. Possible cause: no assembly name specified.  

            //改為  <property name="dialect">NHibernate.Dialect.MySQLDialect</property>   即可

            ISessionFactory sessionFactory = cfg.BuildSessionFactory();//建立Session工廠

            ISession session = sessionFactory.OpenSession();//開啟session

            NHibernate.Demo.QuickStartClassLib.User user = new NHibernate.Demo.QuickStartClassLib.User { IdentifyId = "009", Email = "[email protected]", CreateTime = DateTime.Now, LastTimeLogOn = DateTime.Now, Name = "dan", NickName = "dandan", PassWord = "123", Phone = "nihao" };

            session.Save(user);

            session.Flush();

            IList<User> users = null;

            IQuery query = session.CreateQuery("from User u where u.Id>=:id");

            query.SetInt32("id", 2);

            users = query.List<User>();

            cUsers = users;

            gvData.DataSource = cUsers;

            gvData.DataBind();

        }

    }

}
