Spring的AOP分为注解和配置两种方式实现. 网上注解的例子比较多.
package trytry.aop;
/** * @author 李晨 * @version 创建时间：Jul 28, 2009 3:01:01 PM */ public class Common {
public void show(){
System.out.println(
"------------------普通----------------");
}
}
package trytry.aop;
/** * @author 李晨 * @version 创建时间：Jul 28, 2009 3:03:08 PM */ public class Check {
public void show(){
System.out.println(
"------------------验证----------------");
}
}
下面是核心的Spring的配置文件applicationContext-aop.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" xmlns:aop ="http://www.springframework.org/schema/aop" xmlns:tx ="http://www.springframework.org/schema/tx" xsi:schemaLocation="

public static void main(String[] args) {
BeanFactory factory=
new ClassPathXmlApplicationContext(

Common c=(Common) factory.getBean(

c.show();
}
}
