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：
1 <?xml version="1.0" encoding="UTF-8"?> 2 <beans xmlns="http://www.springframework.org/schema/beans" 3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 4 xmlns:aop="http://www.springframework.org/schema/aop" 5 xmlns:context="http://www.springframework.org/schema/context" 6 xsi:schemaLocation="http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.1.xsd 7 http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd 8 http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.1.xsd"> 9 10 <!-- 配置bean --> 11 <bean id="arithmeticCalculator" class="com.yl.spring.aop.xml.ArithmeticCalculatorImpl"></bean> 12 13 14 <!-- 配置切面的bean --> 15 <bean id="loggingAspect" class="com.yl.spring.aop.xml.LoggingAspect"></bean> 16 17 <bean id="validationAspect" class="com.yl.spring.aop.xml.ValidationAspect"></bean> 18 19 <!-- 配置AOP --> 20 <aop:config> 21 <!-- 配置切点表达式 --> 22 <aop:pointcut expression="execution(public int com.yl.spring.aop.xml.ArithmeticCalculator.*(..))" id="pointcut"/> 23 <!-- 配置切面及通知 --> 24 <aop:aspect ref="loggingAspect" order="2"> 25 <aop:before method="beforeMethod" pointcut-ref="pointcut"/> 26 <aop:after method="afterMethod" pointcut-ref="pointcut"/> 27 <aop:after-throwing method="afterThrowing" pointcut-ref="pointcut" throwing="e"/> 28 <aop:after-returning method="afterReturning" pointcut-ref="pointcut" returning="result"/> 29 30 <aop:around method="aroundMethod" pointcut-ref="pointcut"/> 31 </aop:aspect> 32 33 <aop:aspect ref="validationAspect" order="1"> 34 <aop:before method="vlidateArgs" pointcut-ref="pointcut"/> 35 </aop:aspect> 36 </aop:config> 37 38 </beans>
