Castle ActiveRecord学习实践(3)配置与初始化

前面两篇文章大致对Castle ActiveRecord 有了了解。现在要运行程序，还有一个重要的步骤没做处理，就是初始化和配置。

先来看看需要配置什么信息

1、使用应用程序配置文件（Web.config 或者App.config）

<configuration>
  <configSections>
    <section name="activeRecord" type="Castle.ActiveRecord.Framework.Config.ActiveRecordSectionHandler,Castle.ActiveRecord"/>
  </configSections>
  <activeRecord isWeb="true">
    <config>
      <add key="hibernate.connection.driver_class" value="NHibernate.Driver.SqlClientDriver"/>
      <add key="dialect" value="NHibernate.Dialect.MsSql2005Dialect"/>
      <add key="hibernate.connection.provider" value="NHibernate.Connection.DriverConnectionProvider"/>
      <add key="connection.connection_string" value="Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\Blog.mdf;Integrated Security=True;User Instance=True"/>
      <add key="proxyfactory.factory_class" value="NHibernate.ByteCode.Castle.ProxyFactoryFactory, NHibernate.ByteCode.Castle"/>
    </config>
  </activeRecord>
    <system.web>
        <compilation debug="true" targetFramework="4.0" />
    </system.web>

</configuration>

初始化代码 Global.asax.cs 引用

protected void Application_Start(object sender, EventArgs e)
{
        IConfigurationSource source = ConfigurationManager.GetSection("activeRecord") as IConfigurationSource;
       //Castle.ActiveRecord.ActiveRecordStarter.Initialize(source, typeof(Post), typeof(Comment),typeof(Tag),typeof(Category),typeof(TagPost));
       Castle.ActiveRecord.ActiveRecordStarter.Initialize(System.Reflection.Assembly.Load("Model"), source);
}

第4行代码为载入目标类型参数 Initialize(IConfigurationSource source, params Type[] types);

第5行为Initialize(Assembly assembly, IConfigurationSource source)

2、XmlConfigurationSource配置

可以使用自己的xml文件来保存配置信息。

ActiveRecordConfig.xml文件

<?xml version="1.0" encoding="utf-8" ?>
<activeRecord isWeb="true">
  <config>
    <add key="hibernate.connection.driver_class" value="NHibernate.Driver.SqlClientDriver"/>
    <add key="dialect" value="NHibernate.Dialect.MsSql2005Dialect"/>
    <add key="hibernate.connection.provider" value="NHibernate.Connection.DriverConnectionProvider"/>
    <add key="connection.connection_string" value="Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\Blog.mdf;Integrated Security=True;User Instance=True"/>
    <add key="proxyfactory.factory_class" value="NHibernate.ByteCode.Castle.ProxyFactoryFactory, NHibernate.ByteCode.Castle"/>
  </config>
</activeRecord>

初始化代码

protected void Application_Start(object sender, EventArgs e)
{
      XmlConfigurationSource source = new XmlConfigurationSource(Server.MapPath("~/ActiveRecordConfig.xml"));
      Castle.ActiveRecord.ActiveRecordStarter.Initialize(System.Reflection.Assembly.Load("Model"), source);
}

注意引入 Castle.ActiveRecord.Framework.Config

3、InPlaceConfigurationSource配置

这种实现是一种硬编码的方式，在实际的使用中并不推荐，但是有时候如果我们的配置信息是动态的获取，则这种方式就会变得非常有用。

protected void Application_Start(object sender, EventArgs e)
{
    InPlaceConfigurationSource source = new InPlaceConfigurationSource();

    Dictionary<string, string> properties = new Dictionary<string, string>();

    properties.Add("hibernate.connection.driver_class", "NHibernate.Driver.SqlClientDriver");

    properties.Add("dialect", "NHibernate.Dialect.MsSql2005Dialect");

    properties.Add("hibernate.connection.provider", "NHibernate.Connection.DriverConnectionProvider");

    properties.Add("connection.connection_string", @"Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\Blog.mdf;Integrated Security=True;User Instance=True");

    properties.Add("proxyfactory.factory_class", "NHibernate.ByteCode.Castle.ProxyFactoryFactory, NHibernate.ByteCode.Castle");

    source.Add(typeof(ActiveRecordBase), properties);

    ActiveRecordStarter.Initialize(System.Reflection.Assembly.Load("Model"), source);
}

注意 需要添加Castle.Core.dll
