spring使用动态代理面向切面编程(AOP) xml

在使用注解的时候，首先得在配置文件bean.xml中添加命名空间：

xmlns:aop="http://www.springframework.org/schema/aop"

 

然后在xsi:schemaLocation中添加：

http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop-2.5.xsd

 

bean.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
