/**
* NamespaceHandler
for the aop
namespace.
*
*
Provides a {@link org.springframework.beans.factory.xml.BeanDefinitionParser} for the
* <aop:config>
tag. A config
tag can include nested
* pointcut
, advisor
and aspect
tags.
*
*
The pointcut
tag allows for creation of named
* {@link AspectJExpressionPointcut} beans using a simple syntax:
*
* <aop:pointcut id="getNameCalls" expression="execution(* *..ITestBean.getName(..))"/> ** *
Using the advisor
tag you can configure an {@link org.springframework.aop.Advisor}
* and have it applied to all relevant beans in you {@link org.springframework.beans.factory.BeanFactory}
* automatically. The advisor
tag supports both in-line and referenced
* {@link org.springframework.aop.Pointcut Pointcuts}:
*
*
* <aop:advisor id="getAgeAdvisor" * pointcut="execution(* *..ITestBean.getAge(..))" * advice-ref="getAgeCounter"/> * * <aop:advisor id="getNameAdvisor" * pointcut-ref="getNameCalls" * advice-ref="getNameCounter"/>* * @author Rob Harrop * @author Adrian Colyer * @author Juergen Hoeller * @since 2.0 */ public class AopNamespaceHandler extends NamespaceHandlerSupport { /** * Register the {@link BeanDefinitionParser BeanDefinitionParsers} for the * '
