Spring.Net学习笔记(1)-容器的使用

一、下载地址：

http://www.springframework.net/download.html

二、相关程序集

Spring.Net容器定义在程序集Spring.Core.dll中，它依赖于Common.Logging.dll。该程序集位于

Spring.NET-1.3.1Spring.NETin et4.0 elease目录下

三、创建容器

1.编程方式的容器

使用Spring.Context.Support.StaticApplicationContxt直接创建容器

public class Person
    {
        public string Name { get; set; }
        public override string ToString()
        {
            return "This is Person";
        }
    }

class Program
{
    static void Main(string[] args)
    {
        //创建容器
        Spring.Context.Support.StaticApplicationContext context = new StaticApplicationContext();

        //注册Person类
        context.RegisterPrototype("Person", typeof(Person), null);

        //从容器中获取Person对象
        Person person = context.GetObject("Person") as Person;

        Console.WriteLine(person);
    }
}

2.使用xml方式(注意xml的输出方式)

处理xml的配置处理器：Spring.Context.Support.XmlApplicationContext

<?xml version="1.0" encoding="utf-8" ?>
<objects xmlns="http://www.springframework.net">
  <object id="Person" type="CPrj.Person,Cprj"></object>
</objects>

class Program
{
    static void Main(string[] args)
    {
        Spring.Context.Support.XmlApplicationContext context = new XmlApplicationContext("objects.xml");
        Person person = context.GetObject("Person") as Person;
        Console.WriteLine(person); 
    }
}

注：<object>的父节点必须是<objects>，且objects的xmlns元素是必须的

3.使用配置文件+xml文件

处理器Spring.Context.Support.ContextHandler在启动程序时候加载配置信息

<?xml version="1.0" encoding="utf-8" ?>
<objects xmlns="http://www.springframework.net">
  <object id="Person" type="CPrj.Person,Cprj"></object>
</objects>

<?xml version="1.0" encoding="utf-8" ?>
<configuration>

  <configSections>
    <sectionGroup name="spring">
      <section name="context" type="Spring.Context.Support.ContextHandler,Spring.Core"></section>
    </sectionGroup>
  </configSections>

  <spring>
    <context>
      <resource uri="file://objects.xml"></resource>
    </context>
  </spring>

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

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

注：context节点的默认type就是 Spring.Context.Support.XmlApplicationContext,Spring.Core 。故可省去

<spring>
  <context type="Spring.Context.Support.XmlApplicationContext,Spring.Core">
    <resource uri="file://objects.xml"></resource>
  </context>
</spring>

4.使用配置文件

xml对象定义也可以放在DotNet的标准应用程序配置文件中，此时必须为<objects>节点预先注册相应的节点处理器

需要使用一个新的配置处理器：Spring.Context.Support.DefaultSectionHandler

它可以帮助我们解析spring配置信息

<?xml version="1.0" encoding="utf-8" ?>
<configuration>

  <configSections>
    <sectionGroup name="spring">
      <section name="context" type="Spring.Context.Support.ContextHandler,Spring.Core"></section>
      <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">
      <object id="Person" type="CPrj.Person,CPrj"></object>
    </objects>
  </spring>

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

class Program
{
    static void Main(string[] args)
    {
        Spring.Context.IApplicationContext context = Spring.Context.Support.ContextRegistry.GetContext();
        Person person = context.GetObject("Person") as Person;
        Console.WriteLine(person);
        Console.ReadKey();
    }
}

注：spring和context节点名称不是任意的，必须是spring和context。Spring.Net本身将“spring/context”作为字符串常亮定义在AbstractApplicationContext类中以表示上下文的节点名称

5.混合使用外部配置文件和嵌入的配置

<?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="file://objects.xml"/>
            <resource uri="config://spring/objects"/>
        </context>
        <objects>
            <object id="Person" type="CPrj.Person,CPrj"></object>
        </objects>
    </spring>
    
</configuration>
