springAOP入口之AopNamespaceHandler.docVIP

springAOP入口之AopNamespaceHandler 我们从spring.handlers入口开始看: http\:///schema/aop=org.springframework.aop.config.AopNamespaceHandler 1 打开类AopNamespaceHandler，代码如下： package org.springframework.aop.config; import org.springframework.aop.aspectj.AspectJExpressionPointcut; import org.springframework.beans.factory.xml.BeanDefinitionParser; import org.springframework.beans.factory.xml.NamespaceHandlerSupport; /** * {@code NamespaceHandler} for the {@code aop} namespace. * * pProvides a {@link org.springframework.beans.factory.xml.BeanDefinitionParser} for the * {@code lt;aop:configgt;} tag. A {@code config} tag can include nested * {@code pointcut}, {@code advisor} and {@code aspect} tags. * * pThe {@code pointcut} tag allows for creation of named * {@link AspectJExpressionPointcut} beans using a simple syntax: * pre class=code * lt;aop:pointcut id=quot;getNameCallsquot; expression=quot;execution(* *..ITestBean.getName(..))quot;/gt; * /pre * * pUsing the {@code 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 {@code advisor} tag supports both in-line and referenced * {@link org.springframework.aop.Pointcut Pointcuts}: * * pre class=code * lt;aop:advisor id=quot;getAgeAdvisorquot; * pointcut=quot;execution(* *..ITestBean.getAge(..))quot; * advice-ref=quot;getAgeCounterquot;/gt; * * lt;aop:advisor id=quot;getNameAdvisorquot; * pointcut-ref=quot;getNameCallsquot; * advice-ref=quot;getNameCounterquot;/gt;/pre * * @author Rob Harrop * @author Adrian Colyer * @author Juergen Hoeller * @since 2.0 */ public class AopNamespaceHandler extends NamespaceHandlerSupport { /** * Register the {@link BeanDefinitionParser BeanDefinitionParsers} for the * {@code config}, {@code spring-configured}, {@code aspectj-autoproxy} * and {@code scoped-proxy} tags. */ @Override p
