Spring.Net学习笔记-方法注入

Posted 2020-07-02 Kimisme

一、开发环境

系统：win10

编译器：VS2013

二、涉及程序集

Spring.Core.dll 1.3.1

Common.Logging.dll

三、开发过程

1.项目结构

2.编写Mobile.cs

namespace SpringNetMethodDi
{
    public abstract class Mobile
    {
        //可以是virtual
        public abstract SendTool GetSendTool();
    }
}

3.编写SendTool.cs

namespace SpringNetMethodDi
{
    public class SendTool
    {
        public void WeChat()
        {
            Console.WriteLine("我是Kimisme，正在用微信发信息");
        }
    }
}

4.编写RealOp.cs

namespace SpringNetMethodDi
{
    public class RealOp
    {
        public virtual string Buy(string goods)
        {
            return goods + "是昨天的剩下的";
        }
    }
}

5.编写SuperMarket.cs

namespace SpringNetMethodDi
{
    public class SuperMarket : IMethodReplacer
    {
        public object Implement(object target, System.Reflection.MethodInfo method, object[] arguments)
        {
            string value = arguments[0].ToString();
            return value + "是今天的面包";
        }
    }
}

6.编写Door.cs

namespace SpringNetMethodDi
{
    public delegate string OpenHandler(string arg);

    public class Door
    {
        public event OpenHandler OpenTheDoor;

        public void OnOpen(string arg)
        {

            if (OpenTheDoor != null)
            {
                Console.WriteLine(OpenTheDoor(arg));
            }
        }
    }
}

7.编写Men.cs

namespace SpringNetMethodDi
{
    public class Men
    {
        public string OpenThisDoor(string arg)
        {
            return "参数是：" + arg;
        }
    }
}

8.编写App.config

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <configSections>
    <sectionGroup name="spring">
      <section name="context" type="Spring.Context.Support.ContextHandler,Spring.Core"/>
      <section name="objects" type="Spring.Context.Support.DefaultSectionHandler,Spring.Core"/>
    </sectionGroup>
  </configSections>

  <spring>
    <context>
      <resource uri="config://spring/objects"></resource>
    </context>
    <objects xmlns="http://www.springframework.net">
      <!--01抽象方法注入-->
      <object name="sendTool" type="SpringNetMethodDi.SendTool,SpringNetMethodDi"></object>
      <object name="mobile" type="SpringNetMethodDi.Mobile,SpringNetMethodDi">
        <lookup-method name="GetSendTool" object="sendTool"/>
      </object>
      <!--02替换方法-->
      <object name="replaceValue" type="SpringNetMethodDi.SuperMarket,SpringNetMethodDi"></object>
      <object name="realOp" type="SpringNetMethodDi.RealOp,SpringNetMethodDi">
        <replaced-method name="Buy" replacer="replaceValue">
          <arg-type match="String"/>
        </replaced-method>
      </object>
      <!--03事件注入-->
      <object id="door" type="SpringNetMethodDi.Door,SpringNetMethodDi"></object>
      <object id="men" type="SpringNetMethodDi.Men,SpringNetMethodDi">
        <listener event="OpenTheDoor" method="OpenThisDoor">
          <ref object="door"/>
        </listener>
      </object>

    </objects>
  </spring>
  <startup>
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
  </startup>
</configuration>

9.控制台代码

namespace SpringNetMethodDi
{
    class Program
    {
        static void Main(string[] args)
        {
            IApplicationContext context = ContextRegistry.GetContext();
            Mobile mobile = context.GetObject("mobile") as Mobile;
            mobile.GetSendTool().WeChat();

            RealOp op = context.GetObject("realOp") as RealOp;
            Console.WriteLine(op.Buy("面包"));

            Door door = context.GetObject("door") as Door;
            door.OnOpen("Opening");
            Console.ReadKey();
        }
    }
}

四、备注

今天又掉进坑了，具体什么坑看问题汇总
