Spring_aop切面编程

1. 先建一个Man类，此具有一个name属性，并且具有两个方法(行为)qq,mm

package MAN;* 具有聊QQ和泡MM两个行为的人的对象。还有一个用户名的属性public class Man {private String name;public String getName() {return name;}public void setName(String name) {this.name = name;}public void qq(){System.out.println("QQ");}public void mm(){System.out.println("我在泡MM");}}

 

2.建一个FBI类

继承MethodBeforeAdvice借口

Public class FBI implements MethodBeforeAdvice(){publicvoid before(Method method, Object[] arg1, Object target)                 throws Throwable {           // TODO Auto-generated method stub      Man man = (Man)target;            System.err.println("FBI发现"+man.getName()+"即将进行"+method.getName()                +"活动");      } }

 

3.配置applicationContext.xml

<bean id="man" class="类所在路径"><property name="属性"><value type="java.lang.String">张三</value></property></bean><bean id="fbi" class="类所在路径" /><bean id="civilian"class="org.springframework.aop.framework.ProxyFactoryBean"><property name="target"><ref bean="man" /></property><property name="interceptorNames"><list><value>fbi</value></list></property></bean>

 

4.编写test类

package MAN;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;import MAN.*;publicclass AOPTest {      publicstaticvoid main(String[] args) {           ApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext.xml");           Man man=(Man)ctx.getBean("civilian");           man.qq();           man.mm();      } }

运行结果：
