castle 组件化开发应用配制示例

示例

Windsor 实现IOC容器配制， 暴露接口，通过配制文件指定接口实现，从而降低系统内部依赖 C# Code：

IWindsorContainer container = 
                new WindsorContainer(
                    new XmlInterpreter(new ConfigResource("castle")));

Interface1 myInstance= container.Resolve<Interface1>("Interface1");
// or 
myInstance= container.Resolve<Interface1>();

 App.Config or Web.config 配制

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <configSections>
    <section  name="castle"   type="Castle.Windsor.Configuration.AppDomain.CastleSectionHandler, Castle.Windsor" />
  </configSections>
  <castle>     
    <include uri="file://castleconfiguration.xml"/>    
  </castle>
</configuration>

castleconfiguration.xml  如果是window应用程序，需要把此配制文件copy到bin目录。Windsor Schema 是用来定义配制文件结构的

注意:

1. 可以配制生命周期：lifestyle=singleton|thread|transient|pooled|custom|
2. 配制构造函数：<parameters>....<参数名>值</参数名>....</parameters>
   

<?xml version="1.0" encoding="utf-8" ?>
<configuration xmlns="MyWindsorSchema">
  <components>
    <component id="httpservicewatcher"  type="GettingStartedPart1.HttpServiceWatcher, GettingStartedPart1">
      <parameters>        
        <notifiers>
          <array>
            <item>${email.notifier}</item>
            <item>${alarm.notifier}</item>
          </array>
        </notifiers>
        <Url>different url</Url>
      </parameters>
    </component>
    <component  id="email.notifier"  service="GettingStartedPart1.IFailureNotifier, GettingStartedPart1"  type="GettingStartedPart1.EmailFailureNotifier, GettingStartedPart1" />
    <component  id="alarm.notifier"  service="GettingStartedPart1.IFailureNotifier, GettingStartedPart1"  type="GettingStartedPart1.AlarmFailureNotifier, GettingStartedPart1" />
    <component  id="form.component"  type="GettingStartedPart1.Form1, GettingStartedPart1"  />
    <component  id="Interface1"     service="GettingStartedPart1.Interface1, GettingStartedPart1" type ="GettingStartedPart1.Class1, GettingStartedPart1" lifestyle="transient" />
    <component  id="Interface2"     service="GettingStartedPart1.Interface1, GettingStartedPart1" type ="GettingStartedPart1.Class2, GettingStartedPart1" lifestyle="transient" />      
  </components>  
</configuration>

Service look up notation

The following notation is used to describe a service reference.

${componentid}

Configuration Property evaluation

This notation is used with a properties node and allows the developer to expand the value on the properties node to as a node value or attribute value. #{propertyname}
