#### 基于XML的AOP实现 ####

基于xml的AOP的实现与基于注解的实现原理一致，只需要了解

*参考基于注解的AOP环境*  
以下为配置文件代码：

<?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans"
           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
           xmlns:comtext="http://www.springframework.org/schema/context"
           xmlns:aop="http://www.springframework.org/schema/aop"
           xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context https://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/aop https://www.springframework.org/schema/aop/spring-aop.xsd">

        <aop:config>
            
            <aop:pointcut id="pointCut" expression="execution(* com.qcw.spring.aop.xml.CalculatorImpl.*(..))"/>
    
            
            <aop:aspect ref="loggerAspect">
                <aop:before method="beforeAdviceMethod" pointcut-ref="pointCut"></aop:before>
                <aop:after method="afterAdviceMethod" pointcut-ref="pointCut"></aop:after>
                <aop:after-returning method="afterReturningAdviseMethod" returning="result" pointcut-ref="pointCut"></aop:after-returning>

                <aop:around method="aroundAdviceMethod" pointcut-ref="pointCut"></aop:around>
            </aop:aspect>
            <aop:aspect ref="validateAspect" order="1">
