初使NHibernate

今天学习了下NHibernate，因为以前JavaEE中使用过Hibernate框架，所以上手很快，但其中还是遇到了些问题，这里把经验给大家分享下：

首先是使用Code Smith生成实体类和映射文件

1. 找到映射文件属性中的生成操作，把这个属性改成嵌入的资源；

2. 添加NHibernate的程序集（.DLL），然后就可以写具体方法了，看代码吧

===================NHibernareHelp==========================

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Data.SqlClient;
using NHibernate;
using NHibernate.Cfg;
using NHibernate.Tool.hbm2ddl;
using NHibernate.Expression;

namespace Demo.DAl
{
    #region NHibernareHelp
    public class NHibernareHelp
    {
        private ISessionFactory _sessionFactory;
        private ISession _session;
        public NHibernareHelp()
        {
            _sessionFactory = GetSessionFactory();
        }
        private ISessionFactory GetSessionFactory()
        {
            return (new Configuration()).Configure().BuildSessionFactory();
        }
        public ISession GetSession()
        {
            if (_session == null)
                return _sessionFactory.OpenSession();
            return _session;
        }

    }
    #endregion
}

===================RoomService==========================

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Demo.Models;
using NHibernate;
using NHibernate.Cfg;
using NHibernate.Tool.hbm2ddl;
using NHibernate.Expression;

namespace Demo.DAl
{
    public class RoomService
    {
       
        private ISession _session;
        public RoomService()
        {
            _session = new NHibernareHelp().GetSession();
        }
        public  IList<Room> GetAllRoom()
        {
            IList<Room> list = _session.GetNamedQuery("[dbo].[proc_room_query]").List<Room>();
            return list;
        }
    }
}

3. 配置文件

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

<hibernate-configuration xmlns="urn:nhibernate-configuration-2.2">
  <session-factory name="NHFactory">
    <property name="connection.provider">NHibernate.Connection.DriverConnectionProvider</property>
    <property name="connection.driver_class">NHibernate.Driver.SqlClientDriver</property>
    <property name="connection.connection_string">Data Source=localhost;Initial Catalog=hotelManageDB;Integrated Security=SSPI</property>
    <property name="show_sql">true</property>
    <property name="dialect">NHibernate.Dialect.MsSql2005Dialect</property>
   
    <mapping assembly="Demo.Models"/>
   
  </session-factory>
</hibernate-configuration>
