Spring.NET的IOC容器解决的，就是如何在应用中将类、对象和服务组合成应用程序的问题。IOC容器通过很正统的方式将分散的组件组合成完整的应用程序。Spring.NET框架就应运而生了。
其中Spring.NET Core是整个矿机阿德基础，实现了依赖注入的功能。Spring.AOP为业务对象提供面向切面编程的支持。Spring.WEB提供了客户端。Spring.Services允许将服务发布为企业服务或远程服务（WCF）。Spring.Data定义了一个抽象的数据访问层，可以跨越各种数据访问技术进行数据访问。Spring.ORM包含生命是事物管理等功能。
在ITOO中我们最终实现的AOP是这样的：
U层调用业务层，业务层调用AOP，这一步使用的AOP中拦截的思想，用特性标签进行实现的，AOP调用Service层，使用的是代理和容器，将远程的服务全部配置在配置文件中，应用代理，运行WCF提供的服务。
AOP项目中：
首先写拦截特性类：COntrollerAttribute类：
<span style="font-size:18px;">using System;
using System.Collections.Generic;
using System.Linq;
using System.ServiceModel.Channels;
using System.ServiceModel.Description;
using System.ServiceModel.Dispatcher;
using System.Web;
namespace AOP
{
[AttributeUsage(AttributeTargets.Method, Inherited = false, AllowMultiple = false)]
public sealed class ControllerAttribute
: Attribute, IOperationBehavior
{
void IOperationBehavior.AddBindingParameters(OperationDescription operationDescription, BindingParameterCollection bindingParameters) { }
void IOperationBehavior.ApplyClientBehavior(OperationDescription operationDescription, ClientOperation clientOperation) { }
void IOperationBehavior.ApplyDispatchBehavior(OperationDescription operationDescription, DispatchOperation dispatchOperation)
{
dispatchOperation.Invoker = new ControllerInvoker(dispatchOperation.Invoker);
}
void IOperationBehavior.Validate(OperationDescription operationDescription) { }
}
}</span>
<span style="font-size:18px;">using ITOO.UINonQueryProperties.Contracts;
using Spring.Context;
using Spring.Context.Support;
using System;
using System.Collections.Generic;
using System.Linq;
using System.ServiceModel;
using System.ServiceModel.Dispatcher;
using System.Web;
namespace AOP
{
internal sealed class ControllerInvoker
: IOperationInvoker
{
private readonly IOperationInvoker Inner;
public ControllerInvoker(IOperationInvoker inner)
{
Inner = inner;
}
public object[] AllocateInputs()
{
return Inner.AllocateInputs();
}
public object Invoke(object instance, object[] inputs, out object[] outputs)
{
// do something before invoking
//Console.WriteLine("12354566778");
object result =Inner.Invoke(instance, inputs, out outputs);
IApplicationContext ctx = ContextRegistry.GetContext();
try
{
//foreach (IAdd proxy in ctx.GetObjectsOfType(typeof(IAdd)).Values)
//{
// Console.WriteLine(string.Format("invocation result is :{0}", proxy.Add(1, 2)));
// (proxy as ICommunicationObject ).Close();
//}
//
IUINonQueryPropertiesService proxy0 = ctx.GetObject("WsHttpBinding_Services") as IUINonQueryPropertiesService; //应用代理模式提供服务的
Console.WriteLine(string.Format("invocation result is :{0}", proxy0.GetOneQueryPropertie("123")));
(proxy0 as ICommunicationObject).Close();
}
catch (Exception ex)
{
Console.WriteLine(ex.StackTrace);
throw;
}
// do something after invoking
return result;
}
public IAsyncResult InvokeBegin(object instance, object[] inputs, AsyncCallback callback, object state)
{
throw new NotSupportedException();
}
public object InvokeEnd(object instance, out object[] outputs, IAsyncResult result)
{
throw new NotSupportedException();
}
public bool IsSynchronous
{
get { return true; }
}
}
}</span>我们配置XML文件，在该文件中进行配置WCF服务：
<span style="font-size:18px;"><?xml version="1.0" encoding="utf-8" ?>
<objects xmlns="http://www.springframework.net"
xmlns:wcf="http://www.springframework.net/wcf">

<wcf:channelFactory channelType="ITOO.UINonQueryProperties.Contracts.IUINonQueryPropertiesService,ITOO.UINonQueryProperties.Contracts"
endpointConfigurationName="WsHttpBinding_Services" id="WsHttpBinding_Services">
</wcf:channelFactory>
</objects></span>
<span style="font-size:18px;"><?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="assembly://AOP/AOP.Config/WCFServiceConfig.xml"></resource>
</context>
</spring>
<system.serviceModel>
<behaviors>
<serviceBehaviors>
<behavior name="">
<serviceMetadata httpGetEnabled="true" />
<serviceDebug includeExceptionDetailInFaults="true" />
</behavior>
</serviceBehaviors>
</behaviors>
<serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
<bindings>
<wsHttpBinding>
<binding name="WsHttpBinding_Default" transactionFlow="true" >
<security mode="None">
<transport clientCredentialType="None" proxyCredentialType="None" realm=""/>
<message clientCredentialType="UserName" algorithmSuite="Default"/>
</security>
</binding>
</wsHttpBinding>
</bindings>
<!--<client>
<endpoint address="http://127.0.0.1:6633/AddService"

</client>-->
<client>
<!--资源服务-->
<!--<endpoint address="http://localhost:9914/Service.svc?wsdl"

</client>
</system.serviceModel>
</configuration></span>
<span style="font-size:18px;">using ITOO.BasicStudent.Contracts;
using ITOO.BasicStudent.ViewModel;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace AOPTest
{
class Program
{
static void Main(string[] args)
{
IBasicStudentService studentService = ServiceStudentFactory.GetStudentInfosService();
List<StudentViewModel> stuclassList = new List<StudentViewModel>();
StudentViewModel stuclass = new StudentViewModel();
studentService.AddOneStudent(stuclass);
}
}
}
</span>
这里我们想要在AddOneStudent中加上服务，那么我们看到在客户端我们只需要在调用AddOneStudent的服务就可以了，具体在切面上有什么服务，我们直接在AOP项目的COntrollerInvoker中写就可以了。
我们想要在AddOneStudent方法上面家服务，就必须要拦截该方法，如果是MVC就可以使用Filter，如果是WCF我们就可以使用特性，一般普通的类都可以使用特性来进行拦截。
因为AddOneStudent为我们的业务，但是，实际上它也是一种WCF提供的远程服务，这个时候，我们就可以在Constract层中的这个方法上加上特性标签。
具体如下：
<span style="font-size:18px;"> /// <summary>
/// 添加单个学生
/// </summary>
/// <param name="student">单个学生实体</param>
/// <returns>bool</returns>
[Controller]
[OperationContract]
void AddOneStudent(StudentViewModel student);</span>
其实，很多上面说到的一些东西，我并不是特别了解，很多都是人家已经写好资料，拿过来用的，知识在于理解，在于整理，在于积累，在于编织。
