博客提到对应Java类的配置方式，可用XML方式实现AOP，且实现情况与Java类配置方式相近，并提及有XML配置文件。

对应于java类的配置方式，同样可以使用xml的方式实现AOP。实现差不多，不多说。

package com.glodon.springdemo7;


import org.aspectj.lang.ProceedingJoinPoint;

public class SimpleProfiler {

  public void profilerBefore() throws Throwable {
    System.out.println("profiler before");
  }

  public void profilerAfter() throws Throwable {
    System.out.println("profiler after");
  }

  public void profilerAfterReturning() throws Throwable {
    System.out.println("profiler after returning");
  }

  public void profilerException() throws Throwable {
    System.out.println("profiler exception");
  }

  public Object profilerAround(ProceedingJoinPoint joinPoint) throws Throwable {
    System.out.println("profiler around start");
    Object obj = joinPoint.proceed();
    System.out.println("profiler around end");
    return obj;
  }
}

xml配置文件：
