1.声明schema，导入命名空间
（1）如果我们想要使用基于xml的spring aop，那么，第一步，我们需要在xml配置文件中声明spring aop schema，导入命名空间，如下这是一个标准的模板
  1. <?xml version="1.0" encoding="UTF-8"?>
  2. <beans xmlns="http://www.springframework.org/schema/beans"
  3.        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  4.        xmlns:aop="http://www.springframework.org/schema/aop"
  5.        xsi:schemaLocation="
  6.         http://www.springframework.org/schema/beans https://www.springframework.org/schema/beans/spring-beans.xsd
  7.         http://www.springframework.org/schema/aop https://www.springframework.org/schema/aop/spring-aop.xsd">
  8.    
  9.    
  11. </beans>
复制代码
（2）在xml配置文件中，所有的切面以及通知等都必须放置于标签内
2.声明一个切面
  1. //定义一个切面类Logger,在其中声明一个前置通知public class Logger {    public void beforePrint() {<?xml version="1.0" encoding="UTF-8"?>
  2. <beans xmlns="http://www.springframework.org/schema/beans"
  3.        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  4.        xmlns:aop="http://www.springframework.org/schema/aop"
  5.        xsi:schemaLocation="
