## Class AopNamespaceHandler

- java.lang.Object
- - org.springframework.beans.factory.xml.NamespaceHandlerSupport
  - - org.springframework.aop.config.AopNamespaceHandler

- All Implemented Interfaces:
    NamespaceHandler

      public class AopNamespaceHandler
      extends NamespaceHandlerSupport

  `NamespaceHandler` for the `aop` namespace.

  Provides a `BeanDefinitionParser` for the `&lt;aop:config&gt;` tag. A `config` tag can include nested `pointcut`, `advisor` and `aspect` tags.

  The `pointcut` tag allows for creation of named `AspectJExpressionPointcut` beans using a simple syntax:

       <aop:pointcut id="getNameCalls" expression="execution(* *..ITestBean.getName(..))"/>

  Using the `advisor` tag you can configure an `Advisor` and have it applied to all relevant beans in you `BeanFactory` automatically. The `advisor` tag supports both in-line and referenced `Pointcuts`:

       <aop:advisor id="getAgeAdvisor"
           pointcut="execution(* *..ITestBean.getAge(..))"
           advice-ref="getAgeCounter"/>

       <aop:advisor id="getNameAdvisor"
           pointcut-ref="getNameCalls"
           advice-ref="getNameCounter"/>
