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:

![None.gif][] <? xml version="1.0" encoding="utf-8" ?>   
![None.gif][]  
![None.gif][] < configuration >   
![None.gif][]   < configSections >   
![None.gif][]     < sectionGroup  name ="spring" >   
![None.gif][]       < section  name ="context"  type ="Spring.Context.Support.WebContextHandler, Spring.Web" />   
![None.gif][]       < section  name ="objects"  type ="Spring.Context.Support.DefaultSectionHandler, Spring.Core" />   
![None.gif][]     </ sectionGroup >   
![None.gif][]     < section  name ="SpringOverrideProperty"  type ="System.Configuration.NameValueSectionHandler" />   
![None.gif][]     < section  name ="nhibernate"  type ="System.Configuration.NameValueSectionHandler, System, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"   />   
![None.gif][]   </ configSections >   
![None.gif][]  
![None.gif][]   < SpringOverrideProperty >   
![None.gif][]     < add  key ="DbProvider.ConnectionString"  value ="Data Source=192.168.1.21;Database=FastSpring20;User ID=sa;Password=oilchem2007;Trusted\_Connection=False" />   
![None.gif][]     < add  key ="SystemInit.IsDebug"  value ="true" />   
![None.gif][]     < add  key ="SystemInit.Level"  value ="4" />   
![None.gif][]   </ SpringOverrideProperty >   
![None.gif][]    
![None.gif][]  
![None.gif][]      
![None.gif][]   < spring >   
![None.gif][]     < context >   
![None.gif][]       < resource  uri ="config://spring/objects" />   
![None.gif][]       < resource  uri ="assembly://SpringHiberate/SpringHiberate/spring\_bean\_dao.xml" />   
![None.gif][]     </ context >   
![None.gif][]     < objects  xmlns ="http://www.springframework.net" />   
![None.gif][]   </ spring >   
![None.gif][]    
![None.gif][]   < appSettings />   
![None.gif][]  
![None.gif][]   < connectionStrings />   
![None.gif][]  
![None.gif][]   < system.web >   
![None.gif][]     < compilation  debug ="true"   />   
![None.gif][]     < authentication  mode ="Windows"   />   
![None.gif][]      
![None.gif][]     < httpModules >   
![None.gif][]       < add  name ="Spring"  type ="Spring.Context.Support.WebSupportModule, Spring.Web" />   
![None.gif][]     </ httpModules >   
![None.gif][]      
![None.gif][]     < httpHandlers >   
![None.gif][]       < add  verb ="\*"  path ="\*.aspx"  type ="Spring.Web.Support.PageHandlerFactory, Spring.Web" />   
![None.gif][]     </ httpHandlers >   
![None.gif][]   </ system.web >   
![None.gif][] </ configuration >   
![None.gif][]

然后我们添加一个Model类User.cs:

1 ![None.gif][] using  System;  
  2 ![None.gif][]  
  3 ![None.gif][] namespace  SpringHiberate.dao.model  
  4 ![ExpandedBlockStart.gif][] \{  
 5![InBlock.gif][]    public class User  
 6![ExpandedSubBlockStart.gif][]    \{  
 7![InBlock.gif][]        private Int32 id;  
 8![InBlock.gif][]  
 9![InBlock.gif][]        public Int32 Id  
10![ExpandedSubBlockStart.gif][]        \{  
11![ExpandedSubBlockStart.gif][]            get \{ return id; \}  
12![ExpandedSubBlockStart.gif][]            set \{ id = value; \}  
13![ExpandedSubBlockEnd.gif][]        \}  
14![InBlock.gif][]        private string name;  
15![InBlock.gif][]  
16![InBlock.gif][]        public string Name  
17![ExpandedSubBlockStart.gif][]        \{  
18![ExpandedSubBlockStart.gif][]            get \{ return name; \}  
19![ExpandedSubBlockStart.gif][]            set \{ name = value; \}  
20![ExpandedSubBlockEnd.gif][]        \}  
21![InBlock.gif][]        private string email;  
22![InBlock.gif][]  
23![InBlock.gif][]        public string Email  
24![ExpandedSubBlockStart.gif][]        \{  
25![ExpandedSubBlockStart.gif][]            get \{ return email; \}  
26![ExpandedSubBlockStart.gif][]            set \{ email = value; \}  
27![ExpandedSubBlockEnd.gif][]        \}  
28![ExpandedSubBlockEnd.gif][]    \}  
29![ExpandedBlockEnd.gif][]\}

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

![None.gif][] <? xml version="1.0" encoding="utf-8"  ?>   
![None.gif][] < hibernate-mapping  xmlns ="urn:nhibernate-mapping-2.2" >   
![None.gif][]   < class  name ="SpringHiberate.dao.model.User,SpringHiberate"  table ="FS\_User"  lazy ="false" >   
![None.gif][]     < id  name ="Id"  column ="id"  type ="Int32" >   
![None.gif][]       < generator  class ="native"   />   
![None.gif][]     </ id >   
![None.gif][]     < property  name ="Name"  column ="uname"  type ="String"  length ="50"   />   
![None.gif][]     < property  name ="Email"  column ="uemail"  type ="String"  length ="50"   />   
![None.gif][]   </ class >   
![None.gif][] </ 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

![None.gif][] <? xml version = " 1.0 "  encoding = " utf-8 "   ?>   
![None.gif][] < objects xmlns = " http://www.springframework.net "   
![None.gif][]         xmlns:xsi = " http://www.w3.org/2001/XMLSchema-instance "   
![None.gif][]         xsi:schemaLocation = " http://www.springframework.net http://www.springframework.net/xsd/spring-objects.xsd " >   
![None.gif][]  
![None.gif][]   < object  id = " DbProvider "  type = " SpringHiberate.dao.SQLProvider, SpringHiberate " >   
![None.gif][]     < property name = " ConnectionString "  value = " Data Source=192.168.1.21;Database=FastSpring20;User ID=sa;Password=oilchem2007;Trusted\_Connection=False "   />   
![None.gif][]   </ object >

![None.gif][]   </ object >

![None.gif][]     < property name = " UserDao "   ref = " UserDao "   />   
![None.gif][]   </ object >   
![None.gif][] </ objects >

修改Default.aspx.cs文件里的内容:

using  System;  
 using  System.Data;  
 using  System.Configuration;  
 using  System.Collections;  
 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  SpringHiberate.spring;  
 using  SpringHiberate.dao;  
  
 namespace  SpringHiberate  
\{  
     public   partial   class  \_Default : System.Web.UI.Page  
    \{    
         private  UserDao userDao;  
  
         public  UserDao UserDao  
        \{  
             get  \{  return  userDao; \}  
             set  \{ userDao  =  value; \}  
        \}  
  
  
         protected   void  Page\_Load( object  sender, EventArgs e)  
        \{  
            Response.Write(hello.Name);  
            SpringHiberate.dao.model.User u  =   new  SpringHiberate.dao.model.User();  
            u.Name  =   " safa " ;  
            u.Email  =   " eicesoft@126.com " ;  
            userDao.Save(u);  
        \}  
    \}  
\}

好了,完成了.很简单吧.下面运行一下,然后看看数据库是不是新建了一条数据.  
Spring.Net简化了数据框架NHibernate的操作.对页面进行注入,实现了松耦合.  
Spring.Net远远不止这些.其他的方面在以后的文章中继续介绍
