从基类继承时 Spring.Net 拦截器不会触发答案

【问题标题】：Spring.Net Interceptors not firing when inherited from a base class从基类继承时 Spring.Net 拦截器不会触发

【问题描述】：

我在使用 Spring.Net 的 AOP 时遇到问题。如果给定的方法是从基类继承的方法，拦截器似乎不会触发。

但是，如果我重写从基类继承的方法，拦截器就会触发。

有没有办法让拦截器在不覆盖基地的情况下开火？

这是我目前所拥有的：（this example 的修改版）：

public class HomeController : BaseController
{
    //**Uncommenting this will work**
    //public override void Delete()
    //{
    //    base.Delete();
    //}
}

public class BaseController : Controller
{
    [SetMethodInfoAsMessage]
    public virtual void Delete()
    {

    }
}

public class SetMethodInfoAsMessageAdvice : IMethodBeforeAdvice
{
    public void Before(MethodInfo method, object[] args, object target)
    {
        //Do something
    }
}

public class SetMethodInfoAsMessageAttribute : Attribute
{
}

使用以下配置：

<?xml version="1.0" encoding="utf-8"?>
<objects xmlns="http://www.springframework.net"
         xmlns:aop="http://www.springframework.net/aop" >

  <!-- Controllers -->
  <object type="MyApp.Controllers.HomeController, MyApp" singleton="false" />

  <!-- Aop -->
  <object id="myInterceptor" type="Spring.Aop.Support.AttributeMatchMethodPointcutAdvisor, Spring.Aop">
    <property name="Attribute" value="MyApp.Controllers.SetMethodInfoAsMessageAttribute, MyApp" />
    <property name="Advice">
      <object type="MyApp.Controllers.SetMethodInfoAsMessageAdvice, MyApp" />
    </property>
  </object>

  <object type="Spring.Aop.Framework.AutoProxy.InheritanceBasedAopConfigurer, Spring.Aop">
    <property name="ObjectNames">
      <list>
        <value>*Controller*</value>
      </list>
    </property>
    <property name="InterceptorNames">
      <list>
        <value>myInterceptor</value>
      </list>
    </property>
  </object>
</objects>

【解决方案1】：

找到了。显然，InheritanceBasedAopConfigurer 中有一个属性调用 ProxyDeclaredMembersOnly 可以启用此行为。最终的 Config 如下所示：

<?xml version="1.0" encoding="utf-8"?>
<objects xmlns="http://www.springframework.net"
         xmlns:aop="http://www.springframework.net/aop" >

  <!-- Controllers -->
  <object type="MyApp.Controllers.HomeController, MyApp" singleton="false" />

  <!-- Aop -->
  <object id="myInterceptor" type="Spring.Aop.Support.AttributeMatchMethodPointcutAdvisor, Spring.Aop">
    <property name="Attribute" value="MyApp.Controllers.SetMethodInfoAsMessageAttribute, MyApp" />
    <property name="Advice">
      <object type="MyApp.Controllers.SetMethodInfoAsMessageAdvice, MyApp" />
    </property>
  </object>

  <object type="Spring.Aop.Framework.AutoProxy.InheritanceBasedAopConfigurer, Spring.Aop">
    <property name="ProxyDeclaredMembersOnly" value="false" />
    <property name="ObjectNames">
      <list>
        <value>*Controller*</value>
      </list>
    </property>
    <property name="InterceptorNames">
      <list>
        <value>myInterceptor</value>
      </list>
    </property>
  </object>
</objects>
