?objects标签是我们配置加载对象的地方。

??加载对象

??? 看过PetShop源代码的人对这项功能可能很熟悉，不再累述，举例说明：
???
????以下代码加载Speaker类。
???
?? Speaker 类的代码。

using?System;
using?System.Collections.Generic;
using?System.Text;

namespace?SpringExample
{
????public?class?Speaker
????{
????????private?string?_name?=?"Not?Modify";

????????public?string?Name
????????{
????????????get?{?return?_name;?}
????????????set?{?_name?=?value;?}
????????}
????????private?IName?_nameInterface;
????????public?Speaker()
????????{
?
????????}
????????public?Speaker(string?name)
????????{
????????????_name?=?name;
????????}
????????public?IName?NameInterface
????????{
????????????set?{?_nameInterface?=?value;?}
????????????get?{?return?_nameInterface;?}
????????}

????????
????}
}

按照以下步骤加载Speaker类。

1.在App.Config中配置Speaker?类的信息，注意在objects标签下。

<object?name="Speaker"??????type="SpringExample.Speaker,?SpringExample">
?</object>

2.以下为调用代码

using?Spring.Context;
using?Spring.Context.Support;

????private?void?button1_Click(object?sender,?EventArgs?e)
????????{
????????????/*普通调用*/
????????????IApplicationContext?ctx?=?ContextRegistry.GetContext();
????????????Speaker?speaker?=?(Speaker)ctx.GetObject("Speaker");
????????????MessageBox.Show(speaker.Name);
????????}

?执行结果为“No Modify”


?属性注入和构造函数注入

???? 注入方式有几种，可以参考Rod Johnson的《Spring框架高级编程》（Java）。?这里只以上述两种方式举例。

???? Speaker类的NameInterface属性是获取IName这样的接口，我们可以在Spring.Net中配置信息，让Speaker创建后就已经有了一个可以使用的IName接口。

??? 以下为IName和NameImpl类的代码。

using?System;
using?System.Collections.Generic;
using?System.Text;

namespace?SpringExample
{
????public?interface?IName
????{
????????string?MyName();
????}
}

using?System;
using?System.Collections.Generic;
using?System.Text;

namespace?SpringExample
{
????public?class?NameImpl:IName
????{
????????#region?IName?Members

????????public?string?MyName()
????????{
????????????return?"From?Spring";
????????}

????????#endregion
????}
}

????
?1.配置App.Config，为Speaker类的NameInteface属性注入NameImpl类。

??????<object?name="Speaker"??????type="SpringExample.Speaker,?SpringExample">
????????<property?name="NameInterface"?ref="Impl"/>
??????</object>
??????<object?name="Impl"????????type="SpringExample.NameImpl,?SpringExample">
??????</object>

?2.调用代码如下：

using?Spring.Context;
using?Spring.Context.Support;

??private?void?button3_Click(object?sender,?EventArgs?e)
????????{
????????????/*属性注入*/
????????????IApplicationContext?ctx?=?ContextRegistry.GetContext();
????????????Speaker?speaker?=?(Speaker)ctx.GetObject("Speaker");
????????????MessageBox.Show(speaker.NameInterface.MyName());
????????}

? 执行结果是"From Spring".

?构造函数注入：

??? 注意看Speaker类有一个含有一个参数的构造函数，我们这次要配置该参数的值由配置文件传入。
???
? 1.配置App.Config，为Speaker类的构造函数传入参数。

<object?name="Speaker"??????type="SpringExample.Speaker,?SpringExample">
????????<constructor-arg?index="0"?value="From?Construct"/>
?????
??????</object>

???
?2.调用代码如下：

using?Spring.Context;
using?Spring.Context.Support;

?private?void?button2_Click(object?sender,?EventArgs?e)
????????{
????????????/*构造注入*/
????????????IApplicationContext?ctx?=?ContextRegistry.GetContext();
????????????Speaker?speaker?=?(Speaker)ctx.GetObject("Speaker");
????????????MessageBox.Show(speaker.Name);
????????}

执行结果为：From Consturct

?? 好了剩下的就是大家举一反三，从三到万了。

程序还需要引用antlr.runtime程序集

IApplicationContext ctx = ContextRegistry.GetContext()中出现问题：

1."Spring.Context.Support.ContextRegistry”的类型初始值设定项引发异常" 没有引用Common.Logging.dll

2.Error creating context 'spring.root': 元素 命名空间“http://www.springframework.net”中的“object”。 的子元素 命名空间“http://www.springframework.net”中的“constructor-arg”。 无效。应为可能元素的列表: 命名空间“http://www.springframework.net”中的“property, lookup-method, replaced-method, listener”。

原因：App.Config中constructor-arg 配置要要放在属性前面。
