Posted 2020-06-18 shamgod

一、

1.配置文件为xml时则切面类不用写aop的anotation

 1 package com.springinaction.springidol;
 2 
 3 public class Magician implements MindReader {
 4   private String thoughts;
 5 
 6   public void interceptThoughts(String thoughts) {
 7     System.out.println("Intercepting volunteer‘s thoughts");
 8     this.thoughts = thoughts;
 9   }
10 
11   public String getThoughts() {
12     return thoughts;
13   }
14 }
