spring3.0 动态代理AOP

1.使用声明式AOP配置需要两个额外的jar包，aspectjweaver.jar和cglib-nodep-2.1_3.jar

2.配置文件：

<?xml version="1.0" encoding="UTF-8"?>  
<beans xmlns="http://www.springframework.org/schema/beans" 
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
       xmlns:context="http://www.springframework.org/schema/context" 
       xmlns:aop="http://www.springframework.org/schema/aop" 
       xsi:schemaLocation="http://www.springframework.org/schema/beans  
           http://www.springframework.org/schema/beans/spring-beans-3.0.xsd  
           http://www.springframework.org/schema/context

           http://www.springframework.org/schema/aop  
           http://www.springframework.org/schema/aop/spring-aop-3.0.xsd  
           ">  

 <bean id="BeforeAdvice" class="com.BeforeAdvice"/><!--切面bean-->
 
 <aop:config>
  <aop:aspect ref="BeforeAdvice"> <!--引用切面bean-->
   <aop:before method="before" pointcut="execution(* com.DataBasePlugin.*(..))"/> <!--定义切入点-->
  </aop:aspect>
 </aop:config>
 
</beans>
