IOC:Inversion Of Control

控制翻转：就是创建对象的权利由开发人员自己控制，转换到了由容器来控制

我用的是winform里的一个按键来触发的

首先要引入两个SPRing.net的dll文件Common.Logging.dll 和Spring.Core.dll

    private void button1_Click(object sender, EventArgs e)        {                        IapplicationContext ctx = ContextRegistry.GetContext();            UserInfoService userInfo = (UserInfoService)ctx.GetObject("UserInfoService");            userInfo.Show();        }

    public class UserInfoService    {        public UserInfo user { get; set; }
　　　　//构造函数        public UserInfoService(int age)        {            Age = age;        }        public int Age { get; set; }        public string serverName { get; set; }        public void Show()        {            Console.WriteLine("OK2------"+serverName);            Console.WriteLine("Age=" + Age);            Console.WriteLine("User=" + user.uName);        }    }}

//user类型
namespace SpringDemo{    public class UserInfo    {        public string uName { get; set; }    }}

之后就直接在app.config里注入代码就可以了

<?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 uri="file://Servicess.xml"/>    </context>    <objects xmlns="http://www.springframework.net">      <description>An  example that demonstrates simple IoC features.</description>      <object name="UserInfoService" type="SpringDemo.UserInfoService, SpringDemo ">        <constructor-arg name="age" value="18"/>//--------构造函数注入        <property name="serverName" value="yang"/>//------------属性注入        <property name="user" ref="UserInfo"/>              </object>      <object name="UserInfo" type="SpringDemo.UserInfo, SpringDemo ">//-----user类型的注入        <property name="uName" value="yang2"/>      </object>    </objects>  </spring></configuration>
