Spring AOP--基于XML文件的配置

Spring AOP的配置可以基于注解，也可以基于XML文件。前面几篇都是使用注解的方式。下面介绍下使用XML文件如何配置

使用的测试类和切面类都类似。只需要属于AOP的注解去掉即可。下面是AOP的XML配置：

 <?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:aop="http://www.springframework.org/schema/aop"
     xmlns:context="http://www.springframework.org/schema/context"
     xsi:schemaLocation="http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.1.xsd
         http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
         http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.1.xsd">

     <!-- 配置bean -->
     <bean id="arithmeticCalculator" class="com.yl.spring.aop.xml.ArithmeticCalculatorImpl"></bean>

     <!-- 配置切面的bean -->
     <bean id="loggingAspect" class="com.yl.spring.aop.xml.LoggingAspect"></bean>

     <bean id="validationAspect" class="com.yl.spring.aop.xml.ValidationAspect"></bean>

     <!-- 配置AOP -->
     <aop:config>
         <!-- 配置切点表达式 -->
         <aop:pointcut expression="execution(public int com.yl.spring.aop.xml.ArithmeticCalculator.*(..))" id="pointcut"/>
         <!-- 配置切面及通知 -->
         <aop:aspect ref="loggingAspect" order="2">
             <aop:before method="beforeMethod" pointcut-ref="pointcut"/>
             <aop:after method="afterMethod" pointcut-ref="pointcut"/>
             <aop:after-throwing method="afterThrowing" pointcut-ref="pointcut" throwing="e"/>
             <aop:after-returning method="afterReturning" pointcut-ref="pointcut" returning="result"/>

             <aop:around method="aroundMethod" pointcut-ref="pointcut"/>
         </aop:aspect>

         <aop:aspect ref="validationAspect" order="1">
             <aop:before method="vlidateArgs" pointcut-ref="pointcut"/>
         </aop:aspect>
     </aop:config>

 </beans>
