1、搭建项目基本框架:

(1)创建MVC项目,命名为NHShop.Web。

(2)依次分别新建3个类库项目:NHShop.Domain,NHShop.Data,NHShop.Business。此项目采用传统三层架构:

  NHShop.Data引用Iesi.Collections.dll、NHibernate.dll和类库NHShop.Domain。

  NHShop.Business引用类库NHShop.Domain和NHShop.Data。

  NHShop.Web需引用Iesi.Collections.dll、NHibernate.dll和类库NHShop.Domain、NHShop.Business。

2、配置数据库连接信息:

  打开packages文件夹,找到NHibernate.4.1.1.4000文件夹下的ConfigurationTemplates文件夹,复制MSSQL.cfg.xml到NHShop.Web跟目录,并重命名为hibernate.xml,注意将部分property改为id

  修改hibernate.xml,修改数据库实例名,并添加mapping节点,修改后如下:

"1.0" encoding="utf-8"?>


"urn:nhibernate-configuration-2.2" >
    "NHibernate.Test">
    
        "connection.driver_class">NHibernate.Driver.SqlClientDriver"connection.connection_string">
      Server=WYT\SQLEXPRESS;database=Northwind;uid=sa;pwd=123456
    "dialect">NHibernate.Dialect.MsSql2008Dialect"NHShop.Domain" />
    

 


3、修改hibernate.xml的属性为:如果比较则复制

4、单例模式编写NHibernateHelper辅助类NHibernateHelper:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using NHibernate;
using NHibernate.Cfg;

namespace NHShop.Data
{
    public class NHibernateHelper
    {
        private static ISessionFactory _sessionFactory;

        /// 
        /// 创建ISessionFactory
        /// 
        public static ISessionFactory SessionFactory
        {
            get { 
                //配置ISessionFactory
                return _sessionFactory==null?(new Configuration()).Configure().BuildSessionFactory():_sessionFactory;
            }
        }
    }
}

5、NHShop.Domain利用动软代码生成器生成持久化类Customers:

using System;

//Nhibernate Code Generation Template 1.0
//author:MythXin
//blog:www.cnblogs.com/MythXin
//Entity Code Generation Template
namespace NHShop.Domain.Entities
{
    //Customers
    public class Customers
    {

        /// 
        /// CustomerID
        /// 
        public virtual string CustomerID
        {
            get;
            set;
        }
        /// 
        /// CompanyName
        /// 
        public virtual string CompanyName
        {
            get;
            set;
        }
        /// 
        /// ContactName
        /// 
        public virtual string ContactName
        {
            get;
            set;
        }
        /// 
        /// ContactTitle
        /// 
        public virtual string ContactTitle
        {
            get;
            set;
        }
        /// 
        /// Address
        /// 
        public virtual string Address
        {
            get;
            set;
        }
        /// 
        /// City
        /// 
        public virtual string City
        {
            get;
            set;
        }
        /// 
        /// Region
        /// 
        public virtual string Region
        {
            get;
            set;
        }
        /// 
        /// PostalCode
        /// 
        public virtual string PostalCode
        {
            get;
            set;
        }
        /// 
        /// Country
        /// 
        public virtual string Country
        {
            get;
            set;
        }
        /// 
        /// Phone
        /// 
        public virtual string Phone
        {
            get;
            set;
        }
        /// 
        /// Fax
        /// 
        public virtual string Fax
        {
            get;
            set;
        }

    }
}

6、NHShop.Domain利用动软代码生成器生成映射文件:Customers.hbm.xml,并给文件设置属性:嵌入的资源

"1.0"  encoding="utf-8" ?>
"urn:nhibernate-mapping-2.2" assembly="NHShop.Domain" namespace="NHShop.Domain.Entities">
  
  class name="NHShop.Domain.Entities.Customers, NHShop.Domain" table="Customers">


    "CustomerID" column="CustomerID" type="string"  />
    "CompanyName" column="CompanyName" type="string"  />
    "ContactName" column="ContactName" type="string"  />
    "ContactTitle" column="ContactTitle" type="string"  />
    "Address" column="Address" type="string"  />
    "City" column="City" type="string"  />
    "Region" column="Region" type="string"  />
    "PostalCode" column="PostalCode" type="string"  />
    "Country" column="Country" type="string"  />
    "Phone" column="Phone" type="string"  />
    "Fax" column="Fax" type="string"  />

  class>

7、NHShop.Data添加数据访问层类:CustomersData

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using NHibernate;
using NHShop.Domain.Entities;
using NHibernate.Linq;
using System.Linq.Expressions;

namespace NHShop.Data
{
    public class CustomersData
    {
        /// 
        /// 根据条件得到客户信息集合
        /// 
        /// 
        /// 
        public IList GetCustomerList(Expressionbool>> where)
        {
            try
            {
                using (ISession session=NHibernateHelper.SessionFactory.OpenSession())
                {
                    return session.Query().Select(x => new Customers {
                        CustomerID = x.CustomerID,
                        ContactName = x.ContactName,
                        City = x.City,
                        Address = x.Address,
                        Phone = x.Phone,
                        CompanyName = x.CompanyName,
                        Country = x.Country
                    }).Where(where).ToList() ;
                }
            }
            catch (Exception ex)
            {
                
                throw ex;
            }
        }
    }
}

8、NHShop.Business添加业务逻辑类:CustomersBusiness

using NHShop.Data;
using NHShop.Domain.Entities;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Linq.Expressions;
using System.Text;
using System.Threading.Tasks;

namespace NHShop.Business
{
    public class CustomersBusiness
    {
        private CustomersData _customersData;

        public CustomersBusiness()
        {
            _customersData = new CustomersData();
        }

        /// 
        /// 根据条件得到客户信息集合
        /// 
        /// 
        /// 
        public IList GetCustomersList(Expressionbool>> where)
        {
            return _customersData.GetCustomerList(where);
        }
    }
}

9、NHShop.Web添加控制器和视图:Customers
