SPRING IN ACTION 第4版笔记-第四章ASPECT-ORIENTED SPRING-009-带参数的ADVICE2 配置文件为XML

一、

1.配置文件为xml时则切面类不用写aop的anotation

 package com.springinaction.springidol;

 public class Magician implements MindReader {
   private String thoughts;

   public void interceptThoughts(String thoughts) {
     System.out.println("Intercepting volunteer's thoughts");
     this.thoughts = thoughts;
   }

   public String getThoughts() {
     return thoughts;
   }
 }
