Nhibernate（1）

概念的东西就不多写 直接上个实例
数据库sql05

create database test
go
use test
go
create table Animals(
AnimalID int primary key,
AnimalType varchar(50)
)
go

实体层Model

using System;
using System.Collections.Generic;
using System.Text;

namespace Model
{
    public class Animals
    {
        public int _Animalsid;
        public string _Animalsname;

        public int AnimalID
        {
            set { this._Animalsid = value; }
            get { return this._Animalsid; }
        }

        public string AnimalType
        {
            get { return this._Animalsname; }
            set { this._Animalsname = value; }
        }
    }
}

实体映射文件（最讨厌的东西）Animals.hbm.xml

<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2">
  <class name ="Model.Animals,Model" table="Animals" lazy="false" >
    <id name="AnimalID" column="AnimalID" type="Int32">
      <generator class ="native" />
    </id>
    <property name="AnimalType" column ="AnimalType" type="String" length="50" not-null="true"/>
  </class>
</hibernate-mapping>

ps:XML文件的默认生成操作为“内容”，这里需要修改为“嵌入的资源”生成

数据层DAL
在这里写一个session管理类 SessionManager

using System;
using System.Collections.Generic;
using System.Text;
using NHibernate.Cfg;
using NHibernate;
namespace DAL
{
   public class SessionManger
    {
        static readonly object key = new object();
        static Configuration config;
        static ISessionFactory sessionfactory;

       public static ISession GetIsession()
       {
           if (sessionfactory == null)
           {
               lock (key)
               {
                   if (sessionfactory == null)
                   {
                       config = new Configuration().Configure();
                       sessionfactory = config.BuildSessionFactory();
                   }
               }
           }
           return sessionfactory.OpenSession();
       }

    }
}

写一个添加方法试试

using System;
using System.Collections.Generic;
using System.Text;
using NHibernate;
namespace DAL
{
   public class AnimalsDAL
    {
       ISession session;
       public AnimalsDAL()
       {
           session = SessionManger.GetIsession();
       }
       public bool Add(Model.Animals animal)
       {
           bool flag = false;
           ITransaction tran = session.BeginTransaction();
           try
           {
               session.Save(animal);
               tran.Commit();
               flag = true;
           }
           catch(Exception ex) {
                 tran.Rollback();
                 throw ex;
           }
           finally {
               session.Close();
           }
           return flag;
       }
    }
}

业务逻辑层BLL
也没什么逻辑啦 就添加方法

using System;
using System.Collections.Generic;
using System.Text;

namespace BLL
{
    public  class AnimalsBLL
    {
        public bool Add(Model.Animals animal)
        {
            return new DAL.AnimalsDAL().Add(animal);
        }
    }
}

表现层：调用

   Animals a = new Animals();
        a.AnimalType = "pig";
        AnimalsBLL animalbll = new AnimalsBLL();
        animalbll.Add(a);

别忘记了配置文件：

<?xml version="1.0" encoding="utf-8" ?>
<hibernate-configuration  xmlns="urn:nhibernate-configuration-2.2" >
  <session-factory name="NHibernate.Test">
    <!-- properties -->
    <property name="connection.provider">NHibernate.Connection.DriverConnectionProvider</property>
    <property name="connection.driver_class">NHibernate.Driver.SqlClientDriver</property>
    <property name="connection.connection_string">Server=localhost;initial catalog=test;Integrated Security=SSPI</property>
    <property name="show_sql">true</property>
    <property name="dialect">NHibernate.Dialect.MsSql2005Dialect</property>
    <property name="use_outer_join">true</property>
    <property name="query.substitutions">true 1, false 0, yes 'Y', no 'N'</property>
    <property name="proxyfactory.factory_class">NHibernate.ByteCode.LinFu.ProxyFactoryFactory, NHibernate.ByteCode.LinFu</property>

    <!-- mapping files -->
    <mapping assembly="Model" />
  </session-factory>
</hibernate-configuration>
