一、
you can also define pointcuts that can be used across multiple aspects by placing the <aop:pointcut> elements within the scope of the <aop:config> element.
1.其他类和上个例子一样，观众类比使用@AspectJ方式的少了@AspectJ标签及pointcut，before、after等定义
1 package com.springinaction.springidol; 2 3 public class Audience { 4 public void takeSeats() { //<co id="co_takeSeats"/> 5 System.out.println("The audience is taking their seats."); 6 } 7 8 public void turnOffCellPhones() { //<co id="co_turnOffCellPhones"/> 9 System.out.println("The audience is turning off their cellphones"); 10 } 11 12 public void applaud() { //<co id="co_applaud"/> 13 System.out.println("CLAP CLAP CLAP CLAP CLAP"); 14 } 15 16 public void demandRefund() { //<co id="co_demandRefund"/> 17 System.out.println("Boo! We want our money back!"); 18 } 19 }
2.xml(由于直接在xml定义切面，所以不用写<AOP:ASPECTJ-AUTOPROXY>)
