Castle ActiveRecord学习笔记三：初始化配置

Posted 2020-09-19 杨铭宇

在使用Castle ActiveRecord的时候，需要两种方式来进行初始化，一种就是通过配置文件，另外一种就是将初始配置进行硬编码，写到程序中来。

当然，一般来说，利用配置文件来进行将会大大简化后期维护，我们首先在程序中添加一个App.config的配置文件，记住，一定要将这个配置文件的生成操作设置为“嵌入的资源”才行。否则会提示如学习笔记二中所出现的问题。

具体的配置如下：

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <config>
      <add key="connection.driver_class" value="NHibernate.Driver.SqlClientDriver"/>
      <add key="dialect" value="NHibernate.Dialect.MsSql2008Dialect"/>
      <add key="connection.provider" value="NHibernate.Connection.DriverConnectionProvider"/>
      <add key="proxyfactory.factory_class" value="NHibernate.ByteCode.Castle.ProxyFactoryFactory, NHibernate.ByteCode.Castle"/>
      <add key="connection.connection_string" value="UID=sa;Password=*****;Initial Catalog=NewsDemo;Data Source=."/>
    </config>
</configuration>

然后在程序中的编码如下：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using Castle.ActiveRecord.Framework;
using System.Configuration;
using Castle.ActiveRecord;
using Castle.ActiveRecord.Framework.Config;
using System.Collections;
using CastleLib;

namespace CastleAPP
{
    publicpartialclass MainFrm : Form
    {
        public MainFrm()
        {
            InitializeComponent();
            Init();
        }

        privatevoid Init()
        {
            XmlConfigurationSource source =new XmlConfigurationSource("http://www.cnblogs.com/App.config");
            ActiveRecordStarter.Initialize(source, typeof(CastleLib.User);
        }

        privatevoid Form1_Load(object sender, EventArgs e)
        {
            AddUsers();
            IList list = CastleLib.User.FindAll();

            dataGridView1.DataSource = list;
        }

        publicvoid AddUsers()
        {
            CastleLib.User user =new CastleLib.User();
            user.Name ="石朝阳";
            user.Password ="ceshi";
            user.Address ="河南省信阳市";
            user.LastLogon = DateTime.Now;
            user.Create();
        }
    }
}

而如果使用硬编码的方式，则相对来说简单一些，只需要申明一个字典类，然后将操作activerecord的键值对写入，最后调用Initialize方法载入即可。具体的代码如下：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using Castle.ActiveRecord.Framework;
using System.Configuration;
using Castle.ActiveRecord;
using Castle.ActiveRecord.Framework.Config;
using System.Collections;
using CastleLib;

namespace CastleAPP
{
    publicpartialclass MainFrm : Form
    {
        public MainFrm()
        {
            InitializeComponent();
            Init();
        }

        privatevoid Init()
        {
            InPlaceConfigurationSource source = new InPlaceConfigurationSource();
            IDictionary<string, string> properties = new Dictionary<string, string>();
            properties.Add("connection.driver_class", "NHibernate.Driver.SqlClientDriver");
            properties.Add("dialect", "NHibernate.Dialect.MsSql2008Dialect");
            properties.Add("connection.provider", "NHibernate.Connection.DriverConnectionProvider");
            properties.Add("proxyfactory.factory_class", "NHibernate.ByteCode.Castle.ProxyFactoryFactory, NHibernate.ByteCode.Castle");
            properties.Add("connection.connection_string", "UID=sa;Password=*****;Initial Catalog=NewsDemo;Data Source=.;");
            source.Add(typeof(ActiveRecordBase), properties);
            ActiveRecordStarter.Initialize(source, typeof(CastleLib.User));
        }

        privatevoid Form1_Load(object sender, EventArgs e)
        {
            AddUsers();
            IList list = CastleLib.User.FindAll();

            dataGridView1.DataSource = list;
        }

        publicvoid AddUsers()
        {
            CastleLib.User user =new CastleLib.User();
            user.Name ="石朝阳";
            user.Password ="ceshi";
            user.Address ="河南省信阳市";
            user.LastLogon = DateTime.Now;
            user.Create();
        }
    }
}

希望有用。
