使用xml / app.config配置Castle Windsor

use*_*995 5 castle-windsor castle xml-configuration

我目前正在使用Castle Windsor构建示例应用程序。座右铭是使用xml / app.config来打开/关闭方法拦截。我之前使用过Fluent API,它很吸引人。下一步,我尝试将fluent API替换为xml。

代码的主要内容如下:一个名为RandomOperations的类,带有两个虚拟方法。一个实现IInterceptor的LoggingAspect类。一个MyInterceptorsSelector类,该类实现IModelInterceptorsSelector A Program.cs,该Program.cs以前具有流畅的api语法,现在仅用于对RandomOperations类的方法进行调用。一个名为app.config的部分,其中包含注册组件的xml语法。

使用流畅的api时,我可以截获方法调用,但无法使用xml / app.config注册来完成。有人可以告诉我们错过了什么吗?

这些类如下:

RandomOperations.cs

public class RandomOperations 
    {
        public virtual int MyRandomMethod(int x)
        {
            return x * x;
        }

        public virtual void Writer(string x)
        {
            Console.WriteLine(x);
        }
    }

LoggingAspect.cs

public class LoggingAspect : IInterceptor
    {
        public void Intercept(IInvocation invocation)
        {
            Console.WriteLine("Intercepted the call to " + invocation.Method.Name);
            invocation.Proceed();
            Console.WriteLine("After the method call, the return value is " + invocation.ReturnValue);
        }
    }

MyInterceptorsSelector.cs

public class MyInterceptorsSelector : IModelInterceptorsSelector
    {

        public bool HasInterceptors(ComponentModel model)
        {
            return typeof(LoggingAspect) != model.Implementation &&
                model.Implementation.Namespace.StartsWith("ConsoleApplication1") ;
        }

        public InterceptorReference[] SelectInterceptors(ComponentModel model, Castle.Core.InterceptorReference[] obj)
        {
            var interceptors = new List<InterceptorReference>(model.Interceptors.Count + 1);
            foreach (InterceptorReference inter in model.Interceptors)
            {
                interceptors.Add(inter);
            }

            return interceptors.ToArray();

        }

        {
            var container = new WindsorContainer();
            //container.Register(Component.For<RandomOperations>().Interceptors(typeof(LoggingAspect)));
            //container.Register(Component.For<LoggingAspect>());

删除注释掉的流利的api语法可使应用程序正常工作。

App.config

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

  <castle>
    <components>

      <component id="MyInterceptorsSelector" type="MyInterceptorsSelector"/>
      <component
        id="LoggingAspect"
        type="ConsoleApplication1.LoggingAspect, ConsoleApplication1">
      </component>
      <component
        type="ConsoleApplication1.RandomOperations, ConsoleApplication1">
        <interceptors selector="${MyInterceptorsSelector}">
          <interceptor>${LoggingAspect}</interceptor>
        </interceptors>
      </component>

    </components>
  </castle>
  <startup>

您需要将一个传递IConfigurationInterpreter给您的Windsor构造函数。更改:

var container = new WindsorContainer();

至:

var container = new WindsorContainer(new XmlInterpreter());

XmlInterpreter(不带参数)会选择您的app.config / web.config配置。
