数据库名：Nhibernate
use NHibernate
go
CREATE TABLE users (
  LogonID nvarchar(20) NOT NULL default '0',
  Name nvarchar(40) default NULL,
  Password nvarchar(20) default NULL,
  EmailAddress nvarchar(40) default NULL,
  PRIMARY KEY  (LogonID)
)
go

数据表：users

二、总体介绍

项目名：WebNhibernate

界面：WebForm.aspx

具体表现文件：WebForm.aspx.cs

实体类文件：EntityClass.cs

映射文件：Userhbm.xml

配置文件：Web.config

三、创建Web界面

类型

Text属性值

Label
Label1
ID:

Label
Label2
姓名：

Label
Label3
密码：

Label
Label4
Email：

Label
Labmessage
  

TextBox
TxtId
  

TextBox
TxtName
  

TextBox
TxtPassword
  

TextBox
TxtEmail
  

Button
ButSave
添加

Button
ButDel
删除

Button
ButUpdata
修改

四、创建映射文件（xml文件）和实体类

实体类

using System;

namespace WebNhibernate

{

     public class EntityClass

     {

          private string id;

          private string userName;

          private string password;

          private string emailAddress;

         public EntityClass()

         {}

         public string Id

         {

              get { return id; }

              set { id = value; }

         }

         public string UserName

         {

              get { return userName; }

              set { userName = value; }

         }

         public string Password

         {

              get { return password; }

              set { password = value; }

         }

         public string EmailAddress

         {

              get { return emailAddress; }

              set { emailAddress = value; }

         }

     }

}

映射文件:

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

<hibernate-mapping xmlns="urn:nhibernate-mapping-2.0">

     <class name="WebNhibernate.EntityClass, WebNhibernate" table="users">

         <id name="Id" column="LogonId" type="String" length="20">

              <generator class="assigned" />

         </id>

          <property name="UserName" column= "Name" type="string" length="40"/>

          <property name="Password" type="string" length="20"/>

          <property name="EmailAddress" type="String" length="40"/>

     </class>

</hibernate-mapping>

注意点：

1．<class name="WebNhibernate.EntityClass, WebNhibernate" table="users">

       WebNhibernate.EntityClass代表：实体类名

    WebNhibernate代表：该项目的装配集名称

      Users代表：数据表名

2．当属性列表<property name=”” column=””/>中既有name和column说明实体层的属性与数据表的字段名不同名

3．指定一个id, 在数据表中就是主键, 这个非常重要,nhibernate就是通过id来判断对象的唯一性的.

五、在配置文件中添加配置内容

1．首先在配置文件的<configuration>代码下面添加如下代码

       <configSections>

             <section name="nhibernate" type="System.Configuration.NameValueSectionHandler, System, Version=1.0.3300.0,Culture=neutral, PublicKeyToken=b77a5c561934e089" />

     </configSections>  

     这一段代码是必须要的

2．在配置文件的</system.web>代码下面添加如下代码

<nhibernate>

         <!—连接数据提供者 -->

         <add

              key="hibernate.connection.provider"          

              value="NHibernate.Connection.DriverConnectionProvider"

         />

         <!—连接数据方言最常用的是MsSql2000Dialect -->

         <add

              key="hibernate.dialect"                      

              value="NHibernate.Dialect.MsSql2000Dialect"

         />

         <!—连接数据驱动类-->

         <add

              key="hibernate.connection.driver_class"          

              value="NHibernate.Driver.SqlClientDriver"

         />

         <!—连接数据库-->

         <add

              key="hibernate.connection.connection_string"

              value="Server=yanfa1;initial catalog=nhibernate;User id=sa;password=8626798;"

         />

</nhibernate>

六、实现代码

首先在文件头添加代码
using NHibernate;
using NHibernate.Cfg;
1.添加数据：

双击“添加“按钮

        private void ButSave_Click(object sender, System.EventArgs e)

         {

              mCfg=new Configuration();//创建配置类

              mCfg.AddXmlFile (System.Web.HttpContext.Current.Server.MapPath("Userhbm.xml"));//指明映射文件Userhbm.xml

              EntityClass vEntity=new EntityClass();

              vEntity.Id=TxtId.Text;

              vEntity.UserName=TxtName.Text;

              vEntity.Password=TxtPassword.Text;

              vEntity.EmailAddress=TxtEmail.Text;

              ISession vSession= mCfg.BuildSessionFactory().OpenSession();//创建会话工厂, 一般来说应该使用一个单例对象来封装会话工厂.

              ITransaction vTransaction = vSession.BeginTransaction();//创建事物处理

              try

              {

                   vSession.Save(vEntity);//向数据库添加数据

                   vTransaction.Commit();

                   Labmessage.Text="OK";

              }

              catch(Exception ex)

              {

                   vTransaction.Rollback();

                   Labmessage.Text="Error"+ex.ToString();

              }

              finally

              {

                   vSession.Close();

              }

         }

2.删除数据：

双击“删除“按钮
        private void ButDel_Click(object sender, System.EventArgs e)

         {

              mCfg=new Configuration();

              mCfg.AddXmlFile (System.Web.HttpContext.Current.Server.MapPath("Userhbm.xml"));

              ISession vSession= mCfg.BuildSessionFactory().OpenSession();

              ITransaction vTransaction = vSession.BeginTransaction();

              try

              {

                   EntityClass vEntity=(EntityClass) vSession.Load(typeof(EntityClass),TxtId.Text);//查找数据表中所要记录

                   vSession.Delete(vEntity);//向数据库删除数据

                   vTransaction.Commit();

                   Labmessage.Text="OK";

              }

              catch(Exception ex)

              {

                   vTransaction.Rollback();

                   Labmessage.Text="Error";

              }

              finally

              {

                   vSession.Close();

              }

         }

3.修改代码：

双击“修改“按钮
        private void ButUpdata_Click(object sender, System.EventArgs e)

         {

              mCfg=new Configuration();

              mCfg.AddXmlFile (System.Web.HttpContext.Current.Server.MapPath("Userhbm.xml"));

              ISession vSession= mCfg.BuildSessionFactory().OpenSession();

              ITransaction vTransaction = vSession.BeginTransaction();

              try

              {

                   EntityClass vEntity=(EntityClass) vSession.Load(typeof(EntityClass),TxtId.Text);

                   vEntity.UserName=TxtName.Text;

                   vEntity.Password=TxtPassword.Text;

                   vEntity.EmailAddress=TxtEmail.Text;

                   vSession.Update(vEntity); //向数据库修改数据

                   vTransaction.Commit();

                   Labmessage.Text="OK";

              }

              catch(Exception ex)

              {

                   vTransaction.Rollback();

                   Labmessage.Text="Error";

              }

              finally

              {

                   vSession.Close();

              }

         }

因本人也是刚接触Nhibernate不久，还有好多技术难点不怎么明白，还需多加努力，愿与大家一起探讨
