Spring学习总结（2）——Spring IOC的前世今生

前些天，参与了公司内部小组的一次技术交流，主要是针对《IOC与AOP》，本着学而时习之的态度及积极分享的精神，我就结合一个小故事来初浅地剖析一下我眼中的“IOC前世今生”，以方便初学者能更直观的来学习与理解IOC！也作抛砖引玉之用。

（虽说故事中的需求有点小，但看客可在脑海中尽量把他放大，想象成一个很大的应用系统）

一、IOC雏形

1、程序V1.0

话说，多年以前UT公司提出一个需求，要提供一个系统，其中有个功能可以在新春佳节之际给公司员工发送一封邮件。邮件中给大家以新春祝福，并告知发放一定数额的过节费。

经分析，决定由张三、李四和王五来负责此系统的开发。

其中：由张三负责业逻辑控制模块 LogicController的开发,此处简化为UT.LogicController.exe ；由李四负责祝福消息管理类（GreetMessageService），并集成到组件 UT.MessageService.dll中；由王五负责邮件功能帮助类（EmailHelper），并提供组件 UT.Email.dll。

王五邮件功能模块核心代码如下：

public class EmailHelper
{
    public void Send(string message)
    {
        Console.Write("Frome email: " + message);
    }
}

李四消息管理模块核心代码如下

public class GreetMessageService
{
    EmailHelper greetTool;

    public GreetMessageService()
    {
        greetTool = new EmailHelper();
    }

    public void Greet(string message)
    {
        greetTool.Send(message);
    }
}

张三业务集成模块核心代码如下：

string message = "新年快乐！过节费5000.";
MessageService.GreetMessageService service = new MessageService.GreetMessageService();
service.Greet(message);

三人经过一个月的艰苦奋战，终于大功告成，系统也在春节其间成功发出问候信。企业如此关怀，给员工带来无比的温暖，因此深受全体员工好评！

春节过后，相应的功能也移植到了与“UT公司”相关的“UT编辑部”和“UT房产”类似的应用当中，并在后继的“元宵”、“端午”、“中秋”等节日中得以广泛应用。

又是一个年关将至……

说真的，过节费的多少，有时可能直接影响整个假日的行程安排、从而影响假日的整体质量，因此部门领导高度重视。而邮件通知的方式，在边远山区常常因为受网 络环境的影响而无法正常收取，许多在外过年的同事对此颇有微词。后经多方考证，决得采用当下非常主流的电话语言播报的方式进行通知。

于是乎，张三、李四、王五又忙起来了。但李四，却有点头疼了，因为他的模块现在不仅在“UT公司”内部使用，而且还在“UT编辑部”和“UT房产”也都有独立运行。如何让此处变化影响最小，就得费点脑筋。为了达到较好的效果，李四决定按以下方式进行整改。

    ①、初始设计方案如下：

首先为了能让不同“祝福方式”能有效替换，决定以“面向接口”的方式来进行分离。

同时，让EmailHelper的邮件通知类和TelephoneHelper的语音播报类都实现此接口。核心代码如下：

public interface ISendable
{
    void Send(string message);
}

public class EmailHelper : ISendable
{
    public void Send(string message)
    {
        Console.Write("Frome email: " + message);
    }
}

public class TelephoneHelper : ISendable
{
    public void Send(string message)
    {
        Console.Write("Frome telephone: " + message);
    }
}

再者，为了方便兼容新旧产品，要求Controller决定当前采用什么方式进行通信，并以参数方式传给消息管理模块，核心代码如下：

public enum SendToolType
{
    Email,
    Telephone,
}

【备注】:上述代码，并不是一个优秀的设计，在后继的优化方案当中将被去除。

public class GreetMessageService
{
    ISendable greetTool;

    public GreetMessageService(SendToolType sendToolType)
    {
        if (sendToolType == SendToolType.Email)
        {
            greetTool = new UT.EmailV20.EmailHelper();
        }
        else if (sendToolType == SendToolType.Telephone)
        {
            greetTool = new UT.TelephoneV20.TelephoneHelper();
        }
    }

    public void Greet(string message)
    {
        greetTool.Send(message);
    }
}

【备注】:上述代码，并不是一个优秀的设计，在后继的优化方案当中将被优化。

最后，业务集成模块结合具体业务需求进行适当的调整，核心代码如下：

string message = "新年快乐！过节费5000.";
GreetMessageService service = new GreetMessageService(SendTool.Telephone);
service.Greet(message);
