1.无注解的Audience
package XMLconcert;
public class Audience {
public void silenceCellPhones() {
System.out.println("Silencing cell phone");
}
public void takeSeats() {
System.out.println("Taking seats");
}
public void applause() {
System.out.println("CLAP CLAP CLAP");
}
public void demandRefund() {
System.out.println("Demanding a refund");
}
}2.通过XML将无注解的Audience声明为切面
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

<bean class="XMLconcert.Classcial"></bean>
<aop:config>
<aop:aspect ref="audience">

<aop:after-throwing pointcut="execution(* XMLconcert.Performance.perform(..))" method="demandRefund"/>
</aop:aspect>
</aop:config> </beans>
或者
<aop:config>
<aop:aspect ref="audience">
<aop:pointcut expression="execution(* XMLconcert.Performance.perform(..))" id="performance"/>
<aop:before pointcut-ref="performance" method="silenceCellPhones"/>
<aop:before pointcut-ref="performance" method="takeSeats"/>
<aop:after-returning pointcut-ref="performance" method="applause"/>
<aop:after-throwing pointcut-ref="performance" method="demandRefund"/>
</aop:aspect>
</aop:config>
或者
替换Audience中的四个方法
public void watchPerformance(ProceedingJoinPoint jp) {
try {
System.out.println("Silencing cell phone");
System.out.println("Taking seats");
jp.proceed();
System.out.println("CLAP CLAP CLAP");
} catch (Throwable e) {
System.out.println("Demanding a refund");
}
}<aop:config>
<aop:aspect ref="audience">
<aop:pointcut expression="execution(* XMLconcert.Performance.perform(..))" id="performance"/>
<aop:around method="watchPerformance" pointcut-ref="performance"/>
</aop:aspect>
</aop:config>
