NHibernate试验的步骤

0. 安装
NHibernate
http://sourceforge.net/project/showfiles.php?group_id=73818
log4net
http://sourceforge.net/project/showfiles.php?group_id=31983&release_id=171808
1. 生成数据库
use master
go
create database NHibernate
go
use NHibernate
go
CREATE TABLE users (
  LogonID nvarchar(20) NOT NULL default '0',
  Name nvarchar(40) default NULL,
  Password nvarchar(20) default NULL,
  EmailAddress nvarchar(40) default NULL,
  LastLogon datetime default NULL,
  PRIMARY KEY  (LogonID)
)
go
2. 生成persistent类: User.cs
using System;
//note, in the Quick Guide, it says NHibernate.Demo.QuickStart
//you could use it, then you need to change the class name in
//the User.hbm.xml file
namespace NHibernate.Examples.QuickStart
{
 public class User
 {
  private string id;
  private string userName;
  private string password;
  private string emailAddress;
  private DateTime lastLogon;
  public User()
  {
  }
  public string Id
  {
   get { return id; }
   set { id = value; }
  }
  public string UserName
  {
   get { return userName; }
   set { userName = value; }
  }
  public string Password
  {
   get { return password; }
   set { password = value; }
  }
  public string EmailAddress
  {
   get { return emailAddress; }
   set { emailAddress = value; }
  }
  public DateTime LastLogon
  {
   get { return lastLogon; }
   set { lastLogon = value; }
  }
 
 }
}
3. 生成影射文件 User.hbm.xml
<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.0">
 <class name="NHibernate.Examples.QuickStart.User, NHibernate.Examples" table="users">
  <id name="Id" column="LogonId" type="String" length="20">
   <generator class="assigned" />
  </id>
  <property name="UserName" column= "Name" type="String" length="40"/>
  <property name="Password" type="String" length="20"/>
  <property name="EmailAddress" type="String" length="40"/>
  <property name="LastLogon" type="DateTime"/>
 </class>
</hibernate-mapping>
4. 生成配置文件 TestUser.exe.config
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <configSections>
         <section name="nhibernate" type="System.Configuration.NameValueSectionHandler, System, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b77a5c561934e089, Custom=null" />
         <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />
 </configSections>
 
 <nhibernate>
  <add
   key="hibernate.connection.provider"         
   value="NHibernate.Connection.DriverConnectionProvider"
  />
  <add
   key="hibernate.dialect"                     
   value="NHibernate.Dialect.MsSql2000Dialect"
  />
  <add
   key="hibernate.connection.driver_class"         
   value="NHibernate.Driver.SqlClientDriver"
  />
  <add
   key="hibernate.connection.connection_string"
   value="Server=localhost;initial catalog=nhibernate;Integrated Security=SSPI"
  />
 </nhibernate>
 <log4net>
  <appender name="ConsoleAppender" type="log4net.Appender.ConsoleAppender">
   <layout type="log4net.Layout.PatternLayout">
    <param name="ConversionPattern" value="%d [%t] %-5p %c [%x] -%m%n" />
   </layout>
   <root>
    <level value="INFO" />
    <appender-ref ref="ConsoleAppender" />
   </root>
  </appender>
 </log4net>
</configuration>
 
 
5. 生成测试程序:TestUser.cs
using System;
//using System.Configurations;
using NHibernate;
using NHibernate.Cfg;
using System.Collections;
using NHibernate.Examples.QuickStart;
using NHibernate.Expression;
class TestConfig
{
  public static void Main()
  {
 Configuration cfg = new Configuration();
 cfg.AddAssembly("NHibernate.Examples");
 ISessionFactory factory = cfg.BuildSessionFactory();
 ISession session = factory.OpenSession();
 ITransaction transaction = session.BeginTransaction();
 
 User newUser = new User();
 newUser.Id = "joe_cool";
 newUser.UserName = "Joseph Cool";
 newUser.Password = "abc123";
 newUser.EmailAddress = " [email protected]";
 newUser.LastLogon = DateTime.Now;
  
 // Tell NHibernate that this object should be saved
 session.Save(newUser);
 // commit all of the changes to the DB and close the ISession
 transaction.Commit();
 session.Close();
 
 Console.WriteLine("go check in the database, enter return to continue....");
 Console.ReadLine();
 //System.Threading.Thread.Sleep(2000);
 //Console.WriteLine("enter return to continue....");
 //Console.ReadLine();
 // open another session to retrieve the just inserted user
 session = factory.OpenSession();
 User joeCool = (User)session.Load(typeof(User), "joe_cool");
 // set Joe Cool's Last Login property
 joeCool.LastLogon = DateTime.Now;
 session.Update(joeCool);
 // flush the changes from the Session to the Database
 session.Flush();
 //Console.WriteLine("enter return to continue....");
 //Console.ReadLine();
 IList userList = session.CreateCriteria(typeof(User)).List();
 foreach(User user in userList)
 {
  Console.WriteLine(user.Id + " last logged in at " + user.LastLogon);
 }
 IList recentUsers = session.CreateCriteria(typeof(User))
     .Add(Expression.Gt("LastLogon", new DateTime(2004, 03, 14, 20, 0, 0)))
     .List();
 foreach(User user in recentUsers)
 {
  Console.WriteLine(user.Id + " last logged in at " + user.LastLogon);
 }
 
 session.Close();
  }
}
6. copy or reference
NHibernate.dll
HashCodeProvider.dll (needed at runtime)
log4net.dll (needed at runtime)
7. compile User.cs:
csc /t:library /out:NHibernate.Examples.dll /resource:User.hbm.xml User.cs
8. compile TestUser.cs:
csc /r:NHibernate.dll,NHibernate.Examples.dll TestUser.cs
9. run TestUser.exe
F:\test>TestUser
go check in the database, enter return to continue....
