[转]Castle.Windsor依赖注入的高级应用_Castle.Windsor.3.1.0

1. 使用代码方式进行组件注册【依赖服务类】

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>

    /// 管理类

    /// </summary>

    public partial class Mgr

    {

        private static IWindsorContainer container = null;

        /// <summary>

        /// 自定义容器和组件注册

        /// </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();

                //加入组件：旧版

                //tmpContainer.AddComponent("CastleDemo.Lib.Oracle.OracleDatabase", typeof(IDatabase), objTypeA);

                //tmpContainer.AddComponent("CastleDemo.Lib.Sql.SqlDatabase", typeof(IDatabase), objTypeB);

                //加入组件：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. 使用代码方式进行组件注册【不需要依赖】【类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>

    /// 管理类

    /// </summary>

    public partial class Container

    {

        private static IWindsorContainer container = null;

        /// <summary>

        /// 自定义容器和组件注册

        /// </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();

                //加入组件：旧版

                //tmpContainer.AddComponent("CastleDemo.Lib.Oracle.OracleDatabase", objType, objTypeA);

                //tmpContainer.AddComponent("CastleDemo.Lib.Sql.SqlDatabase", objType, objTypeB);

                //加入组件：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. 使用配置文件进行组件注册【不需要依赖】

3.1. 定义配置文件

<?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. 读取config配置文件进行组件注册

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>

        /// 根据配置文件里的服务名生成对象

        /// </summary>

        public static void GetFrom_Config()

        {

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

            string vServiceName = "CastleDemo.Lib.Oracle.OracleDatabase";//服务名

            vServiceName = "CastleDemo.Lib.Sql.SqlDatabase";

            if (container != null)

            {

                IDatabase db = container.Resolve<IDatabase>(vServiceName);

                if (db != null)

                {

                    db.Select("..........");

                }

            }

        }

    }

}

5. Castle容器的组件生存周期，主要有如下几种

5.1. Singleton : 容器中只有一个实例将被创建

5.2. Transient : 每次请求创建一个新实例

5.3. PerThread: 每线程中只存在一个实例

5.4. PerWebRequest : 每次web请求创建一个新实例

5.5. Pooled ：使用"池化"方式管理组件，可使用PooledWithSize方法设置池的相关属性
