Nhibernate 2.0简单范例

NHibernate官网：http://nhforge.org/

官网只有最新版本，找不到hibernate2.0

下载这里：NHibernate-2.1.2.GA-bin.zip

解压缩后，在里面找这些dll,加入项目参考：

Castle.Core.dll

Castle.DynamicProxy2.dll

Iesi.Colections.dll

Nhibernate.dll

Nhibernate.ByteCode.Castle.dll

先引用这些参考，其它暂时用不到。

以下的例子是NHibernate中文文档.rar中的，因为写的不全，做出来的例子运行成功，查看其它资料做好的完整例子步骤：

1.新建数据库quickstart.(sql2008) ,CatId(char(32)),Name(nvarchar(16)),Sex(nchar(1)),Weight(real)

2.vs2010新建web应用程序QuickStart，新建类Cat.cs:

public class Cat
    {
        public Cat(){}
        public virtual string Id { get; set; }
        public virtual string Name { get; set; }
        public virtual char Sex { get; set; }
        public virtual float Weight { get; set; }
    }

3.新建Cat.hbm.xml

<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2"
                   assembly="QuickStart"
                   namespace="QuickStart"
                   >
  <class name="Cat" table="Cat">
    <id name="Id">
      <column name="CatId" sql-type="char(32)" not-null="true"/>
      <generator class="uuid.hex"/>
    </id>
    <property name="Name">
      <column name="Name" length="16" not-null="true"/>
    </property>
    <property name="Sex"/>
    <property name="Weight"/>
  </class>
</hibernate-mapping>

4.新建hibernate.cfg.xml文件并写入以下内容：

（说明：链接的是sql2008数据库，数据库名字是quickstart。）

<?xml version="1.0" encoding="utf-8" ?>
<hibernate-configuration xmlns="urn:nhibernate-configuration-2.2">
  <session-factory>
    <property name="connection.driver_class">NHibernate.Driver.SqlClientDriver</property>
    <property name="connection.connection_string">Data Source=.\sqlexpress;Initial Catalog=quickstart;Persist Security Info=True;User ID=sa;Password=sa;Pooling=False</property>
    <property name="dialect">NHibernate.Dialect.MsSql2008Dialect</property>
    <property name="use_outer_join">true</property>
    <property name="command_timeout">10</property>
    <property name="query.substitutions">true 1, false 0, yes 'Y', no 'N'</property>
    <property name="proxyfactory.factory_class">
      NHibernate.ByteCode.Castle.ProxyFactoryFactory,
      NHibernate.ByteCode.Castle
    </property>
    <property name="connection.provider">NHibernate.Connection.DriverConnectionProvider</property>
    <property name="adonet.batch_size">10</property>
    <property name="show_sql">true</property>
    <mapping assembly="QuickStart" />
  </session-factory>
</hibernate-configuration>

5.新建NHibernateHelper.cs

using System;
using System.Web;
using NHibernate;
using NHibernate.Cfg;

namespace QuickStart
{
    public sealed class NHibernateHelper
    {
        private const string CurrentSessionKey = "nhibernate.current_session";
        private static ISessionFactory sessionFactory;
        static NHibernateHelper()
        {
            ISessionFactory factory = new Configuration().Configure().BuildSessionFactory();
            sessionFactory = new Configuration().Configure().BuildSessionFactory();
        }
        public static ISession GetCurrentSession()
        {

            HttpContext context = HttpContext.Current;
            ISession currentSession = context.Items[CurrentSessionKey] as ISession;
            if (currentSession == null)
            {
                currentSession = sessionFactory.OpenSession();
                context.Items[CurrentSessionKey] = currentSession;
            }
            return currentSession;
        }
        public static void CloseSession()
        {
            HttpContext context = HttpContext.Current;
            ISession currentSession = context.Items[CurrentSessionKey] as ISession;
            if (currentSession == null) { return; }
            currentSession.Close();
            context.Items.Remove(CurrentSessionKey);
        }
        public static void CloseSessionFactory()
        {
            if (sessionFactory != null)
            {
                sessionFactory.Close();
            }
        }
    }
}

6.编辑Default.aspx

Name:<asp:TextBox ID="txtName" Text="" runat="server" />
Sex:<asp:TextBox ID="txtSex" Text="" runat="server" />
Weight:<asp:TextBox ID="txtWeight" Text="" runat="server" />
<asp:Button ID="btnSubmit" Text="Submit" runat="server" OnClick="btnSubmit_Click" />

7.编辑Default.aspx.cs

 protected void btnSubmit_Click(object sender, EventArgs e)
        {
            CatBal.CreateCat(txtName.Text, txtSex.Text, txtWeight.Text);
        }

完。
