 using System;

 using System.Collections.Generic;

 using System.Linq;

 using System.Text;

 using System.Threading.Tasks;

 namespace Castle.ActiveRecord.DB1.Models

 {

     public abstract class DB1ActiveRecordBase : ActiveRecordBase

     {

     }

 }

 using System;

 using System.Collections.Generic;

 using System.Linq;

 using System.Text;

 using System.Threading.Tasks;

 namespace Castle.ActiveRecord.DB1.Models

 {

     [ActiveRecord("Post")]

     public class Post : DB1ActiveRecordBase

     {

         /// <summary>

         /// 自增主键

         /// </summary>

         [PrimaryKey(PrimaryKeyType.Identity, Column = "Id")]

         public int Id { set; get; }

         /// <summary>

         /// 主题

         /// </summary>

         [Property("Subject")]

         public string Subject { set; get; }

         /// <summary>

         public string Text { set; get; }

         /// <summary>

         /// 添加日期

         /// </summary>

         [Property("DateAdded")]

         public DateTime DateAdded { set; get; }

         public static IEnumerable<Post> FindAllBy()

         {

             return FindAll(typeof(Post)).Cast<Post>(); ;

         }

     }

 }

Castle.ActiveRecord.DB2.Models类库添加DB2ActiveRecordBase抽象类文件，继承自ActiveRecordBase基类
添加Post类，继承自DB2ActiveRecordBase抽象类

         {

             return FindAll(typeof(Post)).Cast<Post>(); ;

         }

     }

 }

5.MVC项目ActiveRecord.Demo项目Web.config配置多数据库，主要是config节的type的配置

<configSections>

    <section name="activerecord"

             type="Castle.ActiveRecord.Framework.Config.ActiveRecordSectionHandler, Castle.ActiveRecord" />

  </configSections>

  <connectionStrings>

    <add name="Castle.ActiveRecord.DB1" connectionString="Data Source=.;Initial Catalog=Castle.ActiveRecord.DB1;Integrated Security=SSPI"/>

    <add name="Castle.ActiveRecord.DB2" connectionString="Data Source=.;Initial Catalog=Castle.ActiveRecord.DB2;Integrated Security=SSPI"/>

  </connectionStrings>

  <activerecord isWeb="true">

    <config type="Castle.ActiveRecord.DB1.Models.DB1ActiveRecordBase,Castle.ActiveRecord.DB1.Models">

      <add key="connection.driver_class" value="NHibernate.Driver.SqlClientDriver" />

      <add key="dialect" value="NHibernate.Dialect.MsSql2005Dialect" />

      <add key="connection.provider" value="NHibernate.Connection.DriverConnectionProvider" />

      <add key="connection.connection_string_name" value="Castle.ActiveRecord.DB1" />

      <add key="proxyfactory.factory_class" value="NHibernate.ByteCode.Castle.ProxyFactoryFactory, NHibernate.ByteCode.Castle" />

    </config>

    <config type="Castle.ActiveRecord.DB2.Models.DB2ActiveRecordBase,Castle.ActiveRecord.DB2.Models">

      <add key="connection.driver_class" value="NHibernate.Driver.SqlClientDriver" />

      <add key="dialect" value="NHibernate.Dialect.MsSql2005Dialect" />

      <add key="connection.provider" value="NHibernate.Connection.DriverConnectionProvider" />

      <add key="connection.connection_string_name" value="Castle.ActiveRecord.DB2" />

      <add key="proxyfactory.factory_class" value="NHibernate.ByteCode.Castle.ProxyFactoryFactory, NHibernate.ByteCode.Castle" />

    </config>

  </activerecord>

6.ActiveRecord.Demo项目Global文件Application_Start()方法中初始化ActiveRecord配置

 using Castle.ActiveRecord;

 using Castle.ActiveRecord.Framework;

 using System;

 using System.Collections.Generic;

 using System.Linq;

 using System.Web;

 using System.Web.Mvc;

 using System.Web.Optimization;

 using System.Web.Routing;

 namespace ActiveRecord.Demo

 {

     public class MvcApplication : System.Web.HttpApplication

     {

         protected void Application_Start()

         {

             AreaRegistration.RegisterAllAreas();

             FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);

             RouteConfig.RegisterRoutes(RouteTable.Routes);

             BundleConfig.RegisterBundles(BundleTable.Bundles);

             InitActiveRecord();

         }

         private void InitActiveRecord()

         {

             IConfigurationSource source = System.Configuration.ConfigurationManager.GetSection("activerecord") as IConfigurationSource;

             ActiveRecordStarter.Initialize(source,

                 typeof(Castle.ActiveRecord.DB1.Models.DB1ActiveRecordBase),

                 typeof(Castle.ActiveRecord.DB1.Models.Post),

                 typeof(Castle.ActiveRecord.DB2.Models.DB2ActiveRecordBase),

                 typeof(Castle.ActiveRecord.DB2.Models.Post)

                 );

         }

     }

 }

7.配置现在完成，增加控制器视图，进行两个数据库中Post表数据的显示

新增控制器DB1PostController

 using Castle.ActiveRecord.DB1.Models;

 using System;

 using System.Collections.Generic;

 using System.Linq;

 using System.Web;

 using System.Web.Mvc;

 namespace ActiveRecord.Demo.Controllers

 {

     public class DB1PostController : Controller

     {

         // GET: DB1Post

         public ActionResult Index()

         {

             IEnumerable<Post> post = Post.FindAllBy();

             return View(post);

         }

     }

 }

对应视图：

 @using Castle.ActiveRecord.DB1.Models

 @model IEnumerable<Post>

 @{

     ViewBag.Title = "DB1-Post";

 }

 <h2>DB1-Post</h2>

 <table class="table">

     <thead>

         <tr>

             <th>主键</th>

             <th>主题</th>

             <th>内容</th>

             <th>创建日期</th>

         </tr>

     </thead>

     <tbody>

         @foreach (var m in Model)

         {

             <tr>

                 <td>@m.Id</td>

                 <td>@m.Subject</td>

                 <td>@m.Text</td>

                 <td>@m.DateAdded</td>

             </tr>

         }

     </tbody>

 </table>

新增控制器DB2PostController

 using Castle.ActiveRecord.DB2.Models;

 using System;

 using System.Collections.Generic;

 using System.Linq;

 using System.Web;

 using System.Web.Mvc;

 namespace ActiveRecord.Demo.Controllers

 {

     public class DB2PostController : Controller

     {

         // GET: DB2Post

         public ActionResult Index()

         {

             IEnumerable<Post> post = Post.FindAllBy();

             return View(post);

         }

     }

 }

对应视图：

 @using Castle.ActiveRecord.DB2.Models

 @model IEnumerable<Post>

 @{

     ViewBag.Title = "DB2-Post";

 }

 <h2>DB2-Post</h2>

 <table class="table">

     <thead>

         <tr>

             <th>主键</th>

             <th>主题</th>

             <th>内容</th>

             <th>创建日期</th>

         </tr>

     </thead>

     <tbody>

         @foreach (var m in Model)

         {

             <tr>

                 <td>@m.Id</td>

                 <td>@m.Subject</td>

                 <td>@m.Text</td>

                 <td>@m.DateAdded</td>

             </tr>

         }

     </tbody>

 </table>

8.修改_Layout.cshtml，添加链接进行DB1数据库、DB2数据库表Post数据的显示

 <li>@Html.ActionLink("DB1-Post", "Index", "DB1Post")</li>

 <li>@Html.ActionLink("DB2-Post", "Index", "DB2Post")</li>

运行后效果：
