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;
  }
}
