利用Spring.NET实现WCF的AOP编程

    在WCF中,有时我们希望实现AOP编程,用于权限验证、日志记录等,而Spring.NET就是一种很好的实现工具。

    1、引用Spring.NET相关DLL

    下载Spring.NET包,并在WCF项目中引用相关DLL:

                              

    2、添加WCF服务

    在WCF项目中添加相关WCF服务:

    契约代码:

using System.ServiceModel;

namespace MyWcfTest
{
    [ServiceContract]
    public interface IWcfContract
    {
        [OperationContract]
        string GetData(string value);
    }
}

    服务实现:

namespace MyWcfTest
{
    public class ImplementService : IWcfContract
    {
        public string GetData(string value)
        {
            return string.Format("你输入的是:{0}", value);
        }
    }
}

    添加WcfServer.svc文件:

<%@ ServiceHost Language="C#" Debug="true" Service="WcfServer" Factory="Spring.ServiceModel.Activation.ServiceHostFactory"  %>

    注意,这里添加了Spring.NET的相关Factory,同时Service变成了我们自定义的名字,它在稍后的配置文件中定义。

    3、配置Spring.NET

    添加Spring.NET配置文件MyObjects.xml,内容如下:

<?xml version="1.0" encoding="utf-8" ?>
<objects xmlns="http://www.springframework.net"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.springframework.net
        http://www.springframework.net/xsd/spring-objects.xsd">

  <object type="Spring.Aop.Framework.AutoProxy.TypeNameAutoProxyCreator, Spring.Aop">
    <property name="TypeNames">
      <list>
        <value>*Service*</value>
      </list>
    </property>
    <property name="InterceptorNames">
      <list>
        <value>aroundAdvice</value>
      </list>
    </property>
  </object>

  <object id="aroundAdvisor" type="Spring.Aop.Support.NameMatchMethodPointcutAdvisor, Spring.Aop">
    <property name="Advice" ref="aroundAdvice"/>
    <property name="MappedNames">
      <list>
        <value>Find*</value>
      </list>
    </property>
  </object>

  <object id="aroundAdvice" type="MyWcfTest.MyAroundAdvice, MyWcfTest"/>
  
  <object id="WcfServer" type="MyWcfTest.ImplementService, MyWcfTest" />
  
  <object id="htService1" type="MyWcfTest.Service1, MyWcfTest" />
</objects>

    在WCF应用程序的配置文件Web.config中添加下列配置内容:

  <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="~/MyObjects.xml" />
      <resource uri="config://spring/objects" />
    </context>
    <objects xmlns="http://www.springframework.net" />
  </spring>

   4、注册Spring.NET上下文

    新增应用程序全局设置文件Global.asax,在其中的Application_Start方法中添加下面的代码,用以注册Spring.NET上下文。

        protected void Application_Start(object sender, EventArgs e)
        {
            ContextRegistry.GetContext();
        }

    由此配置完成,即可实现针对WCF的AOP编程。
