Castle学习笔记----将Castle IOC引入项目开发中实现“依赖注入”

Castle学习笔记----将Castle IOC引入项目开发中实现“依赖注入”2011-12-05 博客园 Beniao通常IOC实现的步骤为-->建立容器-->加入组件-->获取组件-->使用组件.这篇文章还是以这四个环节来阐述。

一.建立容器

这里我拿手上的一个现成项目来做分析,首先我们得建立IOC容器.项目中是建立了一个容器类Container来专门负责IOC容器的搭建及组件的加入.代码如下:

 1using System; 2using System.Collections.Generic; 3using System.Text; 4 5using Castle.Windsor; 6using Castle.MicroKernel; 7using Castle.Windsor.Configuration.Interpreters; 8using TMS.Framework.Exceptions; 910namespace TMS.Framework11{12  /**//// <summary>13  /// The IoC container which provides interface to find Service.14  /// </summary>15  public sealed class Container16  {17    /**//// <summary>18    /// WindsorContainer object19    /// </summary>20    private WindsorContainer windsor;21    //public WindsorContainer Windsor22    //{23    //  get { return windsor; }24    //}2526    private IKernel kernel;27    public IKernel Kernel28    {29      get { return kernel; }30    }3132    /**//// <summary>33    /// this34    /// </summary>35    private static readonly Container instance = new Container（）;36    public static Container Instance37    {38      get { return Container.instance; }39    }4041    /**//// <summary>42    /// Construction Method.43    /// Initialization IOC.44    /// </summary>45    public Container（）46    {47      try48      {49        //IOC containers establishment, and through the most dynamic configuration file by adding components.50        Castle.Core.Resource.ConfigResource source = new Castle.Core.Resource.ConfigResource（）;51        XmlInterpreter interpreter = new XmlInterpreter（source）;52        windsor = new WindsorContainer（interpreter）;53        kernel = windsor.Kernel;54      }55      catch （BizSystemException bSE）56      {57        TMSExcetionBase.ProcessBizException（bSE）;58      }59    }6061    /**//// <summary>62    /// Returns a component instance by the type of service.63    /// </summary>64    /// <typeparam name="T"></typeparam>65    /// <returns></returns>66    public T Resolve<T>（）67    {68      return （T）kernel[typeof（T）];69    }7071    /**//// <summary>72    /// Returns a component instance by the service name.73    /// </summary>74    /// <param name="service"></param>75    /// <returns></returns>76    private object Resolve（Type service）77    {78      return kernel[service];79    }8081    /**//// <summary>82    /// Returns a component instance by the service name.83    /// </summary>84    /// <param name="key"></param>85    /// <returns></returns>86    private object Resolve（String key）87    {88      return kernel[key];89    }9091    /**//// <summary>92    /// Release resource that be container used.93    /// </summary>94    public void Dispose（）95    {96      kernel.Dispose（）;97    }98  }99}100

注意：上面代码种的ProcessBizException（）是一个自定义异常处理TMSExcetionBase类的静态方法。
