Castle.ActiveRecord多数据库配置

最近使用Castle.ActiveRecord框架，网上关于多数据支持的文章很少，因此有了这篇博文的产生。

开发工具VS2015,Sql Server2008R2
新建数据库，数据初始化脚本如下：

 1 --新建数据库Castle.ActiveRecord.DB1
 2 CREATE DATABASE [Castle.ActiveRecord.DB1];
 3 GO
 4 
 5 USE [Castle.ActiveRecord.DB1]
 6 GO
 7 /****** Object:  Table [dbo].[Post]    Script Date: 09/25/2016 16:46:21 ******/
 8 SET ANSI_NULLS ON

10 SET QUOTED_IDENTIFIER ON
11 GO
12 CREATE TABLE [dbo].[Post](
13     [Id] [int] IDENTITY(1,1) NOT NULL,
14     [Subject] [nvarchar](64) NULL,
15     [Text] [nvarchar](1024) NULL,
16     [DateAdded] [datetime] NULL,
17 PRIMARY KEY CLUSTERED 
18 (
19     [Id] ASC
20 )WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
21 ) ON [PRIMARY]
22 GO

30 GO
31 SET IDENTITY_INSERT [dbo].[Post] ON
32 INSERT [dbo].[Post] ([Id], [Subject], [Text], [DateAdded]) VALUES (1, N'新闻', N'最新新闻内容', '2016-09-01')
33 INSERT [dbo].[Post] ([Id], [Subject], [Text], [DateAdded]) VALUES (2, N'音乐', N'流行音乐', '2016-09-02')
34 SET IDENTITY_INSERT [dbo].[Post] OFF
35 
36 --新建数据库Castle.ActiveRecord.DB2
37 CREATE DATABASE [Castle.ActiveRecord.DB2];
38 GO
39 
40 USE [Castle.ActiveRecord.DB2]
41 GO
42 /****** Object:  Table [dbo].[Post]    Script Date: 09/25/2016 16:53:05 ******/
43 SET ANSI_NULLS ON
44 GO
45 SET QUOTED_IDENTIFIER ON
46 GO
47 CREATE TABLE [dbo].[Post](
48     [Id] [int] IDENTITY(1,1) NOT NULL,
49     [Subject] [nvarchar](64) NULL,
50     [Text] [nvarchar](1024) NULL,
51     [DateAdded] [datetime] NULL,
52 PRIMARY KEY CLUSTERED 
53 (
54     [Id] ASC
55 )WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
56 ) ON [PRIMARY]
57 GO
58 EXEC sys.sp_addextendedproperty @name=N'MS_Description', @value=N'自增主键' , @level0type=N'SCHEMA',@level0name=N'dbo', @level1type=N'TABLE',@level1name=N'Post', @level2type=N'COLUMN',@level2name=N'Id'

65 GO
66 SET IDENTITY_INSERT [dbo].[Post] ON
67 INSERT [dbo].[Post] ([Id], [Subject], [Text], [DateAdded]) VALUES (1, N'小说', N'纪实小说', '2016-09-03')
68 INSERT [dbo].[Post] ([Id], [Subject], [Text], [DateAdded]) VALUES (2, N'电脑', N'超极本', '2016-09-04')
69 SET IDENTITY_INSERT [dbo].[Post] OFF

3.新建MVC项目ActiveRecord.Demo，新建类库Castle.ActiveRecord.DB1.Models，类库Castle.ActiveRecord.DB2.Models

MVC项目ActiveRecord.Demo文件添加Castle.ActiveRecord框架dll引用，使用NuGut搜索添加.添加对类库Castle.ActiveRecord.DB1.Models，类库Castle.ActiveRecord.DB2.Models的引用。
类库Castle.ActiveRecord.DB1.Models，类库Castle.ActiveRecord.DB2.Models添加Castle.ActiveRecord、NHibernate引用。

　4.Castle.ActiveRecord.DB1.Models类库添加DB1ActiveRecordBase抽象类文件，继承自ActiveRecordBase基类.

　　添加Post类，继承自DB1ActiveRecordBase抽象类

 1 using System;
 2 using System.Collections.Generic;
 3 using System.Linq;
 4 using System.Text;
 5 using System.Threading.Tasks;
 6 
 7 namespace Castle.ActiveRecord.DB1.Models
 8 {
 9     public abstract class DB1ActiveRecordBase : ActiveRecordBase
10     {
11 
12     }
13 }

 1 using System;
 2 using System.Collections.Generic;
 3 using System.Linq;
 4 using System.Text;
 5 using System.Threading.Tasks;
 6 
 7 namespace Castle.ActiveRecord.DB1.Models
 8 {
 9     [ActiveRecord("Post")]
10     public class Post : DB1ActiveRecordBase
11     {
12         /// <summary>
13         /// 自增主键
14         /// </summary>
15         [PrimaryKey(PrimaryKeyType.Identity, Column = "Id")]
16         public int Id { set; get; }
17 
18 
19         /// <summary>
20         /// 主题
21         /// </summary>
22         [Property("Subject")]
23         public string Subject { set; get; }
24 
25 
26         /// <summary>
27         /// 内容
28         /// </summary>
29         [Property("Text")]
30         public string Text { set; get; }
31 
32         /// <summary>
33         /// 添加日期
34         /// </summary>
35         [Property("DateAdded")]
36         public DateTime DateAdded { set; get; }
37 
38         public static IEnumerable<Post> FindAllBy()
39         {
40             return FindAll(typeof(Post)).Cast<Post>(); ;
41         }
42     }
43 }

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

 1 using System;
 2 using System.Collections.Generic;
 3 using System.Linq;
 4 using System.Text;
 5 using System.Threading.Tasks;
 6 
 7 namespace Castle.ActiveRecord.DB2.Models
 8 {
 9     public abstract class DB2ActiveRecordBase : ActiveRecordBase
10     {
11 
12     }
13 }

 1 using System;
 2 using System.Collections.Generic;
 3 using System.Linq;
 4 using System.Text;
 5 using System.Threading.Tasks;
 6 
 7 namespace Castle.ActiveRecord.DB2.Models
 8 {
 9     [ActiveRecord("Post")]
10     public class Post : DB2ActiveRecordBase
11     {
12         /// <summary>
13         /// 自增主键
14         /// </summary>
15         [PrimaryKey(PrimaryKeyType.Identity, Column = "Id")]
16         public int Id { set; get; }
17 
18 
19         /// <summary>
20         /// 主题
21         /// </summary>
22         [Property("Subject")]
23         public string Subject { set; get; }
24 
25 
26         /// <summary>
27         /// 内容
28         /// </summary>
29         [Property("Text")]
30         public string Text { set; get; }
31 
32         /// <summary>
33         /// 添加日期
34         /// </summary>
35         [Property("DateAdded")]
36         public DateTime DateAdded { set; get; }
37 
38         public static IEnumerable<Post> FindAllBy()
39         {
40             return FindAll(typeof(Post)).Cast<Post>(); ;
41         }
42     }
43 }

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

 1 using Castle.ActiveRecord;
 2 using Castle.ActiveRecord.Framework;
 3 using System;
 4 using System.Collections.Generic;
 5 using System.Linq;
 6 using System.Web;
 7 using System.Web.Mvc;
 8 using System.Web.Optimization;
 9 using System.Web.Routing;
10 
11 namespace ActiveRecord.Demo
12 {
13     public class MvcApplication : System.Web.HttpApplication
14     {
15         protected void Application_Start()
16         {
17             AreaRegistration.RegisterAllAreas();
18             FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
19             RouteConfig.RegisterRoutes(RouteTable.Routes);
20             BundleConfig.RegisterBundles(BundleTable.Bundles);
21 
22             InitActiveRecord();
23         }
24 
25         private void InitActiveRecord()
26         {
27             IConfigurationSource source = System.Configuration.ConfigurationManager.GetSection("activerecord") as IConfigurationSource;
28             ActiveRecordStarter.Initialize(source,
29                 typeof(Castle.ActiveRecord.DB1.Models.DB1ActiveRecordBase),
30                 typeof(Castle.ActiveRecord.DB1.Models.Post),
31 
32                 typeof(Castle.ActiveRecord.DB2.Models.DB2ActiveRecordBase),
33                 typeof(Castle.ActiveRecord.DB2.Models.Post)
34                 );
35         }
36     }
37 }

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

 1 using Castle.ActiveRecord.DB1.Models;
 2 using System;
 3 using System.Collections.Generic;
 4 using System.Linq;
 5 using System.Web;
 6 using System.Web.Mvc;
 7 
 8 namespace ActiveRecord.Demo.Controllers
 9 {
10     public class DB1PostController : Controller
11     {
12         // GET: DB1Post
13         public ActionResult Index()
14         {
15             IEnumerable<Post> post = Post.FindAllBy();
16 
17             return View(post);
18         }
19     }
20 }

对应视图：

 1 @using Castle.ActiveRecord.DB1.Models
 2 @model IEnumerable<Post>
 3 @{
 4     ViewBag.Title = "DB1-Post";
 5 }
 6 
 7 <h2>DB1-Post</h2>
 8 <table class="table">
 9     <thead>
10         <tr>
11             <th>主键</th>
12             <th>主题</th>
13             <th>内容</th>
14             <th>创建日期</th>
15         </tr>
16     </thead>
17     <tbody>
18         @foreach (var m in Model)
19         {
20             <tr>
21                 <td>@m.Id</td>
22                 <td>@m.Subject</td>
23                 <td>@m.Text</td>
24                 <td>@m.DateAdded</td>
25             </tr>
26         }
27     </tbody>
28 </table>

新增控制器DB2PostController

 1 using Castle.ActiveRecord.DB2.Models;
 2 using System;
 3 using System.Collections.Generic;
 4 using System.Linq;
 5 using System.Web;
 6 using System.Web.Mvc;
 7 
 8 namespace ActiveRecord.Demo.Controllers
 9 {
10     public class DB2PostController : Controller
11     {
12         // GET: DB2Post
13         public ActionResult Index()
14         {
15             IEnumerable<Post> post = Post.FindAllBy();
16 
17             return View(post);
18         }
19     }
20 }

对应视图：

 1 @using Castle.ActiveRecord.DB2.Models
 2 @model IEnumerable<Post>
 3 @{
 4     ViewBag.Title = "DB2-Post";
 5 }
 6 
 7 <h2>DB2-Post</h2>
 8 <table class="table">
 9     <thead>
10         <tr>
11             <th>主键</th>
12             <th>主题</th>
13             <th>内容</th>
14             <th>创建日期</th>
15         </tr>
16     </thead>
17     <tbody>
18         @foreach (var m in Model)
19         {
20             <tr>
21                 <td>@m.Id</td>
22                 <td>@m.Subject</td>
23                 <td>@m.Text</td>
24                 <td>@m.DateAdded</td>
25             </tr>
26         }
27     </tbody>
28 </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

1 <li>@Html.ActionLink("DB1-Post", "Index", "DB1Post")</li>
2 <li>@Html.ActionLink("DB2-Post", "Index", "DB2Post")</li>
