Spring.Net学习笔记(3)-创建对象

一、开发环境

编译器：VS2013

.Net版本：.net framework4.5

二、涉及程序集

Spring.Core.dll：1.3

Common.Logging

三、开发过程

1.项目结构

2.添加Person.cs

namespace CreateObjects
{
    public class Person
    {
        public override string ToString()
        {
            return "我是Person类";
        }

        public class Heart
        {
            public override string ToString()
            {
                return "我是Heart类";
            }
        }
    }
}

3.添加GenericClass.cs

namespace CreateObjects
{
    public class GenericClass<T>
    {
    }
}

4.添加StaticObjectsFactory.cs

namespace CreateObjects
{
    public static class StaticObjectsFactory
    {
        public static Person CreateInstance()
        {
            return new Person();
        }
    }
}

5.添加InstanceObjectsFactory.cs

namespace CreateObjects
{
    public class InstanceObjectsFactory
    {
        public Person CreateInstance()
        {
            return new Person();
        }
    }
}

6.配置Spring.Net

<?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>
      <!--构造器-->
      <object id="person" type="CreateObjects.Person,CreateObjects"></object>
      <!--嵌套类型-->
      <object id="heart" type="CreateObjects.Person+Heart,CreateObjects"></object>

      <!--泛型类型GenericClass<int>-->
      <object id="genericClass" type="CreateObjects.GenericClass&lt;int>,CreateObjects"></object>

      <!--静态工厂-->
      <object id="staticObjectsFactory"
              type="CreateObjects.StaticObjectsFactory,CreateObjects"
             factory-method="CreateInstance" ></object>

      <!--实例工厂-->
      <!--工厂-->
      <object id="instanceObjectsFactory" type="CreateObjects.InstanceObjectsFactory,CreateObjects"></object>
      <!--创建的对象-->
      <object id="instancePerson" factory-method="CreateInstance" factory-object="instanceObjectsFactory"></object>

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

7.控制台程序如下

namespace CreateObjects
{
    class Program
    {
        static void Main(string[] args)
        {
            IApplicationContext context = ContextRegistry.GetContext();
            Person person = context.GetObject("person") as Person;
            Console.WriteLine(person);

            Person.Heart heart = context.GetObject("heart") as Person.Heart;
            Console.WriteLine(heart);

            GenericClass<int> genericClass = context.GetObject("genericClass") as GenericClass<int>;
            Console.WriteLine(genericClass);

            Person personStaticFactory = context.GetObject("staticObjectsFactory") as Person;
            Console.WriteLine(personStaticFactory);

            Person personInstanceFactory = context.GetObject("instancePerson") as Person;
            Console.WriteLine(personInstanceFactory);
            Console.ReadKey();
        }
    }
}
