1、如何配置数据连接，ActiveRecord初始化的几种方式！

内容属于标准的一些配置，不属于原创文章，只是把一些资料收集，整理在一起而已。

常见的几种数据库配置方案

Castle网站为我们提供的几个常见的配置示例，有的文章说，如果应用于Web 需要在<activerecord>节点配置 <activerecord isWeb="true">  其实不配也没有关系

1．MS SQLServer


<activerecord>




    <config>




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




        <add key="hibernate.dialect" value="NHibernate.Dialect.MsSql2000Dialect" />




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




        <add key="hibernate.connection.connection_string" value="Data Source=.;Initial Catalog=test;UID=sa;Password=sa" />




    </config>




</activerecord>

2．Oracle


<activerecord>




    <config>




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




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




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




        <add key="hibernate.connection.connection_string" value="Data Source=dm;User ID=dm;Password=dm;" />




    </config>




</activerecord>

3．MySQL
 


<activerecord>




    <config>




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




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




        <add key="hibernate.connection.provider" value="NHibernat
4000
e.Connection.DriverConnectionProvider" />




        <add key="hibernate.connection.connection_string" value="Database=test;Data Source=someip;User Id=blah;Password=blah" />




    </config>




</activerecord>
 

4．Firebird
 


<activerecord>




    <config>




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




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




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




        <add key="hibernate.connection.connection_string" value="Server=localhost;Database=d:\db.fdb;User=SYSDBA;password=masterkey;ServerType=1;Pooling=false" />




        <add key="hibernate.query.substitutions" value="true 1, false 0" />




    </config>




</activerecord>
 
5．PostgreSQL


<activerecord>




    <config>




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




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




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




        <add key="hibernate.connection.connection_string" value="Server=localhost;initial catalog=nhibernate;User ID=nhibernate;Password=nhibernate;" />




    </config>




</activerecord>
 
 
 
关于初始化的几种方式：
 
1.初始化单个实体类

ActiveRecordStarter.Initialize( source, typeof(User) );
2.初始化多个实体类

    2.1.   ActiveRecordStarter.Initialize( source, typeof(Order),typeof(Product));

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

Type[] paramTypes = new Type[3];

paramTypes[0] = typeof(User1);

paramTypes[1] = typeof(Post);

paramTypes[2] = typeof(Blog);

ActiveRecordStarter.Initialize(source, paramTypes);

   3.   Assembly assembly = Assembly.Load("ARTest");

   ActiveRecordStarter.Initialize(assembly, source);

   4.    // 获取数据库连接配置

XmlConfigurationSource source = new XmlConfigurationSource(@"Config\ActiveRecord.xml");

      

// 载入程序集中所有 ActiveRecord 类。

ActiveRecordStarter.Initialize(Assembly.GetExecutingAssembly(), source);

   这样可以一次初始化所有的程序集里面的类。
