Spring.Net + NHibernate 入门例子

Spring.Net 是一个很强大的框架,在java里非常的火,NHibernate也是从java里移植过来的.不过和Java下面的用法有所区别.下面我们以一个实例来说说他们在.net下的用法.
新建一个项目:名字叫SpringHiberate.
首先,我们修改我们的配置文件web.config:

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

< configuration >
   < configSections >
     < sectionGroup  name ="spring" >
       < section  name ="context"  type ="Spring.Context.Support.WebContextHandler, Spring.Web" />
       < section  name ="objects"  type ="Spring.Context.Support.DefaultSectionHandler, Spring.Core" />
     </ sectionGroup >
     < section  name ="SpringOverrideProperty"  type ="System.Configuration.NameValueSectionHandler" />
     < section  name ="nhibernate"  type ="System.Configuration.NameValueSectionHandler, System, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"   />
   </ configSections >

   < SpringOverrideProperty >
     < add  key ="DbProvider.ConnectionString"  value ="Data Source=192.168.1.21;Database=FastSpring20;User ID=sa;Password=oilchem2007;Trusted_Connection=False" />
     < add  key ="SystemInit.IsDebug"  value ="true" />
     < add  key ="SystemInit.Level"  value ="4" />
   </ SpringOverrideProperty >
  

   <!--  Spirng.Net 配置  -->
   < spring >
     < context >
       < resource  uri ="config://spring/objects" />
       < resource  uri ="assembly://SpringHiberate/SpringHiberate/spring_bean_dao.xml" />
     </ context >
     < objects  xmlns ="http://www.springframework.net" />
   </ spring >
  
   < appSettings />

   < connectionStrings />

   < system.web >
     < compilation  debug ="true"   />
     < authentication  mode ="Windows"   />
    
     < httpModules >
       < add  name ="Spring"  type ="Spring.Context.Support.WebSupportModule, Spring.Web" />
     </ httpModules >
    
     < httpHandlers >
       < add  verb ="*"  path ="*.aspx"  type ="Spring.Web.Support.PageHandlerFactory, Spring.Web" />
     </ httpHandlers >
   </ system.web >
</ configuration >

然后我们添加一个Model类User.cs:

 1 using  System;
 2
 3 namespace  SpringHiberate.dao.model
 4 {
 5    public class User
 6    {
 7        private Int32 id;
 8
 9        public Int32 Id
10        {
11            get { return id; }
12            set { id = value; }
13        }
14        private string name;
15
16        public string Name
17        {
18            get { return name; }
19            set { name = value; }
20        }
21        private string email;
22
23        public string Email
24        {
25            get { return email; }
26            set { email = value; }
27        }
28    }
29}

我们再在User.cs目录里添加一个文件User.hbm.xml,文件的生成操作为嵌入的资源

<? xml version="1.0" encoding="utf-8"  ?>
< hibernate-mapping  xmlns ="urn:nhibernate-mapping-2.2" >
   < class  name ="SpringHiberate.dao.model.User,SpringHiberate"  table ="FS_User"  lazy ="false" >
     < id  name ="Id"  column ="id"  type ="Int32" >
       < generator  class ="native"   />
     </ id >
     < property  name ="Name"  column ="uname"  type ="String"  length ="50"   />
     < property  name ="Email"  column ="uemail"  type ="String"  length ="50"   />
   </ class >
</ hibernate-mapping >

然后我们写一个SQLProvider类SQLProvider.cs.

using  System;
using  System.Data;
using  System.Configuration;
using  System.Web;
using  System.Web.Security;
using  System.Web.UI;
using  System.Web.UI.WebControls;
using  System.Web.UI.WebControls.WebParts;
using  System.Web.UI.HtmlControls;
using  Spring.Data.Common;

namespace  SpringHiberate.dao
{
     public   class  SQLProvider : IDbProvider
    {
         #region  IDbProvider 成员
         private   string  _connectionString  =   "" ;
         public   string  ConnectionString
        {
             get
            {
                 return   this ._connectionString;
            }
             set
            {
                 this ._connectionString  =  value;
            }
        }

         public  IDbCommand CreateCommand()
        {
             return   null ;
        }

         public   object  CreateCommandBuilder()
        {
             return   null ;
        }

         public  IDbConnection CreateConnection()
        {
             return   null ;
        }

         public  IDbDataAdapter CreateDataAdapter()
        {
             return   null ;
        }

         public  IDbDataParameter CreateParameter()
        {
             return   null ;
        }

         public   string  CreateParameterName( string  name)
        {
             return   null ;
        }

         public   string  CreateParameterNameForCollection( string  name)
        {
             return   null ;
        }

         public  IDbMetadata DbMetadata
        {
             get  {
                 return   null ;
            }
        }

         public   string  ExtractError(Exception e)
        {
             return   null ;
        }

         public   bool  IsDataAccessException(Exception e)
        {
             return   false ;
        }

         #endregion
    }
}

在写一个UserDao类(UserDao.cs)来操作

using  System;
using  System.Collections;
using  Spring.Data.NHibernate.Support;
using  SpringHiberate.dao.model;

namespace  SpringHiberate.dao
{
     public   class  UserDao : HibernateDaoSupport
    {
         public   void  Save(User user)
        {
            HibernateTemplate.Save(user);
        }

         public   void  Delete(User user)
        {
            HibernateTemplate.Delete(user);
        }

         public   void  Update(User user)
        {
            HibernateTemplate.Update(user);
        }

         public  IList FindAll()
        {
             return  HibernateTemplate.LoadAll( typeof (User));
        }

         public  User Find(Object ID)
        {
             return  (User)HibernateTemplate.Load( typeof (User), ID);
        }
    }
}

现在代码部分基本写完,我们开始写spring的配置文件(spring_bean_dao.xml),文件的生成操作也为嵌入的资源,他配置了数据库操作以及DAO部分,页面的操作DAO也是依赖注入的

<? xml version = " 1.0 "  encoding = " utf-8 "   ?>
< objects xmlns = " http://www.springframework.net "
         xmlns:xsi = " http://www.w3.org/2001/XMLSchema-instance "
         xsi:schemaLocation = " http://www.springframework.net http://www.springframework.net/xsd/spring-objects.xsd " >

   < object  id = " DbProvider "  type = " SpringHiberate.dao.SQLProvider, SpringHiberate " >
     < property name = " ConnectionString "  value = " Data Source=192.168.1.21;Database=FastSpring20;User ID=sa;Password=oilchem2007;Trusted_Connection=False "   />
   </ object >

   < object  id = " SessionFactory "  type = " Spring.Data.NHibernate.LocalSessionFactoryObject, Spring.Data.NHibernate12 " >
     < property name = " DbProvider "   ref = " DbProvider "   />
     < property name = " MappingAssemblies " >
       < list >
         < value > SpringHiberate </ value >
       </ list >
     </ property >
     < property name = " HibernateProperties " >
       < dictionary >
         < entry key = " hibernate.connection.provider "  value = " NHibernate.Connection.DriverConnectionProvider "   />
         < entry key = " hibernate.dialect "  value = " NHibernate.Dialect.MsSql2000Dialect "   />
         < entry key = " hibernate.connection.driver_class "  value = " NHibernate.Driver.SqlClientDriver "   />
         < entry key = " show_sql "  value = " true "   />
       </ dictionary >
     </ property >
   </ object >

   < object  id = " HibernateTransactionManager "  type = " Spring.Data.NHibernate.HibernateTransactionManager, Spring.Data.NHibernate12 " >
     < property name = " DbProvider "   ref = " DbProvider "   />
     < property name = " sessionFactory "   ref = " sessionFactory "   />
   </ object >

   < object  id = " TransactionInterceptor "  type = " Spring.Transaction.Interceptor.TransactionInterceptor, Spring.Data " >
     < property name = " TransactionManager "   ref = " HibernateTransactionManager "   />
     < property name = " TransactionAttributeSource " >
       < object  type = " Spring.Transaction.Interceptor.AttributesTransactionAttributeSource, Spring.Data "   />
     </ property >
   </ object >

   < object<span style
