笔记10 在XML中声明切面（1）

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"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:aop="http://www.springframework.org/schema/aop"

        <bean id="audience" class="XMLconcert.Audience"></bean>
        <bean class="XMLconcert.Classcial"></bean>
          <aop:config>
                  <aop:aspect ref="audience">
                      <aop:before pointcut="execution(* XMLconcert.Performance.perform(..))" method="silenceCellPhones"/>
                      <aop:before pointcut="execution(* XMLconcert.Performance.perform(..))" method="takeSeats"/>
                      <aop:after-returning pointcut="execution(* XMLconcert.Performance.perform(..))" method="applause"/>
                      <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>

3.结果
