Castle.Windsor依賴注入的高級應用_Castle.Windsor.3.1.0

[轉]Castle.Windsor依賴注入的高級應用_Castle.Windsor.3.1.0

1. 使用代碼方式進行組件注冊【依賴服務類】

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

using CastleDemo.Lib;


using Castle.Windsor;
using Castle.Windsor.Configuration.Interpreters;
using Castle.MicroKernel.Registration;


namespace CastleDemo.Lib.Mgr
{
    /// <summary>
    /// 管理類
    /// </summary>
    public partial class Mgr
    {
        private static IWindsorContainer container = null;

        /// <summary>
        /// 自定義容器和組件注冊
        /// </summary>
        /// <returns></returns>
        public static IWindsorContainer GetContainer()
        {

            if (container == null)
            {
                Type objTypeA = Type.GetType("CastleDemo.Lib.Oracle.OracleDatabase, CastleDemo.Lib.Oracle");
                Type objTypeB = Type.GetType("CastleDemo.Lib.Sql.SqlDatabase, CastleDemo.Lib.Sql");


                //建立容器
                IWindsorContainer tmpContainer = new WindsorContainer();


                //加入組件：舊版
                //tmpContainer.AddComponent("CastleDemo.Lib.Oracle.OracleDatabase", typeof(IDatabase), objTypeA);
                //tmpContainer.AddComponent("CastleDemo.Lib.Sql.SqlDatabase", typeof(IDatabase), objTypeB);

                //加入組件：新版
                tmpContainer.Register(Component.For(typeof(IDatabase)).ImplementedBy(objTypeA).Named("CastleDemo.Lib.Oracle.OracleDatabase"));
                tmpContainer.Register(Component.For(typeof(IDatabase)).ImplementedBy(objTypeB).Named("CastleDemo.Lib.Sql.SqlDatabase"));
           

                container = tmpContainer;

            }
            return container;
        }
    }
}

 

 

 

2. 使用代碼方式進行組件注冊【不需要依賴】【類似反射的全字符串形式】

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

using Castle.Windsor;
using Castle.Windsor.Configuration.Interpreters;
using Castle.MicroKernel.Registration;

namespace CastleDemo.Lib.Container
{
    /// <summary>
    /// 管理類
    /// </summary>
    public partial class Container
    {
        private static IWindsorContainer container = null;

        /// <summary>
        /// 自定義容器和組件注冊
        /// </summary>
        /// <returns></returns>
        public static IWindsorContainer GetContainer()
        {

            if (container == null)
            {
                Type objType = Type.GetType("CastleDemo.Lib.IDatabase, CastleDemo.Lib");

                Type objTypeA = Type.GetType("CastleDemo.Lib.Oracle.OracleDatabase, CastleDemo.Lib.Oracle");
                Type objTypeB = Type.GetType("CastleDemo.Lib.Sql.SqlDatabase, CastleDemo.Lib.Sql");


                //建立容器
                IWindsorContainer tmpContainer = new WindsorContainer();


                //加入組件：舊版
                //tmpContainer.AddComponent("CastleDemo.Lib.Oracle.OracleDatabase", objType, objTypeA);
                //tmpContainer.AddComponent("CastleDemo.Lib.Sql.SqlDatabase", objType, objTypeB);

                //加入組件：新版
                tmpContainer.Register(Component.For(objType).ImplementedBy(objTypeA).Named("CastleDemo.Lib.Oracle.OracleDatabase"));
                tmpContainer.Register(Component.For(objType).ImplementedBy(objTypeB).Named("CastleDemo.Lib.Sql.SqlDatabase"));
                   
                container = tmpContainer;

            }
            return container;
        }
    }
}

 

 

3. 使用配置文件進行組件注冊【不需要依賴】

3.1. 定義配置文件

<?xml version="1.0"?>
<configuration>
  <configSections>
    <section name="castle" type="Castle.Windsor.Configuration.AppDomain.CastleSectionHandler, Castle.Windsor" />
  </configSections>
  <castle>
    <components>
      <component name="CastleDemo.Lib.Oracle.OracleDatabase" type="CastleDemo.Lib.Oracle.OracleDatabase, CastleDemo.Lib.Oracle" service="CastleDemo.Lib.IDatabase, CastleDemo.Lib"/>
      <component name="CastleDemo.Lib.Sql.SqlDatabase" type="CastleDemo.Lib.Sql.SqlDatabase, CastleDemo.Lib.Sql" service="CastleDemo.Lib.IDatabase, CastleDemo.Lib"/>
    </components>
  </castle>
<startup><supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/></startup></configuration>

 

 

3.2. 讀取config配置文件進行組件注冊

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

using CastleDemo.Lib;


using Castle.Windsor;
using Castle.Windsor.Configuration.Interpreters;
using Castle.MicroKernel.Registration;

namespace CastleDemo.Run
{
    public partial class Helper
    {

        /// <summary>
        /// 根據配置文件里的服務名生成對象
        /// </summary>
        public static void GetFrom_Config()
        {

            IWindsorContainer container = new WindsorContainer(new XmlInterpreter());

            string vServiceName = "CastleDemo.Lib.Oracle.OracleDatabase";//服務名
            vServiceName = "CastleDemo.Lib.Sql.SqlDatabase";

            if (container != null)
            {
                IDatabase db = container.Resolve<IDatabase>(vServiceName);
                if (db != null)
                {
                    db.Select("..........");
                }

            }

        }



    }
}

5. Castle容器的組件生存周期，主要有如下幾種

5.1. Singleton : 容器中只有一個實例將被創建

 

5.2. Transient : 每次請求創建一個新實例

 

5.3. PerThread: 每線程中只存在一個實例

 

5.4. PerWebRequest : 每次web請求創建一個新實例

 

5.5. Pooled ：使用"池化"方式管理組件，可使用PooledWithSize方法設置池的相關屬性
