Spring.net IOC 依赖注入

Spring.net IOC 依赖注入

在配置文件（模版）中对对象属性进行预赋值，然后通过模版创建出来的对象的属性就有了对应的值。

目录

一、引用Spring.Core.dll，Common.Logging.dll

二、新建接口IPerson，新建类Person，Language

三、配置App.config，person1.xml，languages.xml

四、调用

 

一、引用Spring.Core.dll，Common.Logging.dll这个不具体说明了。

二、新建接口IPerson，新建类Person，Language

 接口：IPerson

    public interface IPerson
    {
        void Hello();
    }

 

类：Language

    public class Language
    {
        public string Name { get; set; }
    }

 

类：Person

public class Person :IPerson
{
    public string Name { get; set; }
 
    public List<Language> ListLanguage { get; set; }
 
    public void Hello()
    {
        Console.WriteLine("Hello My Name is {0}", this.Name);
        Console.WriteLine("I will have several languages");
        Console.Write("They are  ");
        if (ListLanguage != null)
        {
            foreach (var item in ListLanguage)
            {
                Console.Write(item.Name +"\t");
            }
        }
 
    }
}

 

 

三、配置App.config，person1.xml，languages.xml

配置app.config

  <!--引用Spring-->
  <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>

  <!--配置模版-->
  <spring>
    <context>
      <!--指向ioc/person1.xml文件-->
      <resource uri="ioc/person1.xml"></resource>
      <resource uri="ioc/languages.xml"></resource>
    </context>
  </spring>

 

配置person1.xml

<?xml version="1.0" encoding="utf-8"?>
<objects xmlns="http://www.springframework.net">
  <object name="person1" type="SpringIOC.Person,SpringIOC">
    <property name="Name" value="Tom"/>
    <property name="ListLanguage">
      <list>
        <ref object="language1"></ref>
        <ref object="language2"></ref>
        <ref object="language3"></ref>
      </list>
    </property>
  </object>
</objects>

 

配置languages.xml

<?xml version="1.0" encoding="utf-8"?>
<objects xmlns="http://www.springframework.net">
  
  <object name="language1" type="SpringIOC.Language,SpringIOC">
    <property name="Name" value="C#"/>
  </object>

  <object name="language2" type="SpringIOC.Language,SpringIOC">
    <property name="Name" value="C++"/>
  </object>

  <object name="language3" type="SpringIOC.Language,SpringIOC">
    <property name="Name" value="Java"/>
  </object>
</objects>

 

四、调用

static void Main(string[] args)
{
    IApplicationContext ctx = ContextRegistry.GetContext();
    IPerson _person = ctx.GetObject<IPerson>("person1");
    if (_person != null)
    {
        _person.Hello();
    }
    Console.Read();
}
