Nhibernate3 step by step (a) - a first program NHibernate

1. Establish Domain Project

  Product.cs

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

namespace NHibernate3.Domain
{
     public  class Product
    {
         ///   <summary>
         ///  ID
         ///   </summary>
         public  virtual Guid ID {  get;  set; }

         ///   <summary>
         ///  编号
         ///   </summary>
         public  virtual  string Code {  get;  set; }

         ///   <summary>
         ///  名称
         ///   </summary>
         public  virtual  string Name {  get;  set; }

         ///   <summary>
         ///  规格
         ///   </summary>
         public  virtual  string QuantityPerUnit {  get;  set; }

         ///   <summary>
         ///  单位
         ///   </summary>
         public  virtual  string Unit {  get;  set; }

         ///   <summary>
         ///  售价
         ///   </summary>
         public  virtual  decimal SellPrice {  get;  set; }

         ///   <summary>
         ///  进价
         ///   </summary>
         public  virtual  decimal BuyPrice {  get;  set; }

         ///   <summary>
         ///  备注
         ///   </summary>
         public  virtual  string Remark {  get;  set; }
    }
}

 

Write mapping file Product.hbm.xml

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

< hibernate-mapping  xmlns ="urn:nhibernate-mapping-2.2"  assembly ="NHibernate3.Domain"  namespace ="NHibernate3.Domain" >
   < class  name ="Product"  table ="T_Product"  lazy ="true"   >
     < id  name ="ID"  column ="ID"  type ="Guid"   >
       < generator  class ="assigned"   />
     </ id >

     < property  name ="Code"  type ="string" >
       < column  name ="Code"  length ="50" />
     </ property >

     < property  name ="Name"  type ="string" >
       < column  name ="Name"  length ="50" />
     </ property >
    
     < property  name ="QuantityPerUnit"  type ="string" >
       < column  name ="QuantityPerUnit"  length ="50" />
     </ property >

     < property  name ="Unit"  type ="string" >
       < column  name ="Unit"  length ="50" />
     </ property >


     < property  name ="SellPrice"  type ="decimal" >
       < column  name ="SellPrice"  precision ="14"  scale ="2" />
     </ property >

     < property  name ="BuyPrice"  type ="decimal" >
       < column  name ="BuyPrice"  precision ="14"  scale ="2" />
     </ property >

     < property  name ="Remark"  type ="string" >
       < column  name ="Remark"  length ="200" />
     </ property >

   </ class >
</ hibernate-mapping >

 

Then, the mapping file "the Product.hbm.xml" attribute " generation method " is set to " embedded resource "

 

 

 

2. Create a test project

  Referenced assembly "Antlr3.Runtime.dll", "Iesi.Collections.dll", "NHibernate.dll", "Remotion.Data.Linq.dll", "nunit.framework.dll", add a reference to the project's Domain

  New Config directory, copy the configuration file template

 

hibernate.cfg.xml

<? xml version="1.0" encoding="utf-8" ?>
<!--  
This template was written to work with NHibernate.Test.
Copy the template to your NHibernate.Test project folder and rename it in hibernate.cfg.xml and change it 
for your own use before compile tests in VisualStudio.
-->
<!--  This is the System.Data.dll provider for SQL Server  -->
< hibernate-configuration   xmlns ="urn:nhibernate-configuration-2.2"   >
     < session-factory  name ="NHibernate3.Test" >
         < property  name ="connection.driver_class" >NHibernate.Driver.SqlClientDriver </ property >
         < property  name ="connection.connection_string" >
      server=.;database=NHibernateDemo;integrated security=SSPI;
     </ property >
         < property  name ="adonet.batch_size" >10 </ property >
         < property  name ="show_sql" >true </ property >
         < property  name ="dialect" >NHibernate.Dialect.MsSql2005Dialect </ property >
         < property  name ="use_outer_join" >true </ property >
         < property  name ="command_timeout" >60 </ property >
     < property  name ="hbm2ddl.auto" >update </ 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  assembly ="NHibernate3.Domain" />
     </ session-factory >
</ hibernate-configuration >

 

Modify the file attributes to " Copy Always "

 

 

 

 

Copy proxyfactory type assembly "LinFu.DynamicProxy.dll" and "NHibernate.ByteCode.LinFu.dll" to the project, and modify the generation mode

 

 

Create a "NHibernateInit.cs" class file that is used to initialize the database table structure

NHibernateInit.cs

 

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

using NHibernate;
using NHibernate.Cfg;

// using NUnit.Framework;

namespace NHibernate3.Test
{
     public  class NHibernateInit
    {
         public  static  void InitTest()
        {
             var cfg =  new NHibernate.Cfg.Configuration().Configure( " Config/hibernate.cfg.xml ");
             using (ISessionFactory sessionFactory = cfg.BuildSessionFactory()) { }
        }
    }
}

 

3. Create a database structure

  In SQL Server2008, it creates a database named "NHibernateDemo" of

  Main method of the console, add the following code:

NHibernateInit.InitTest ();
Console.WriteLine ( " database created successfully! " );

 

Console.Read();

 

4. Run the program

  After the run we found NHibernate automatically create a data table for us T_Product
