<!-- 把那个类注入进来 -->
<bean id="sleepHelper" class="com.test.aop.SleepHelper"/>
<bean id="human" class="com.test.aop.Human"/>
<!-- 配置一个切点 -->
<!-- 配置切点有好几种表达方式 1、配置aspectJ 2.使用正则表达式, 以下使用的是正则表达式 -->
<!-- pattern属性指定了正则表达式,它匹配所有的sleep方法 -->
<bean id="spleepPointcut" class="org.springframework.aop.support.JdkRegexpMethodPointcut">
<property name="pattern" value=".*sleep" />
</bean>
<!-- 切点仅仅是定义了故事发生的地点,还有故事发生的时间以及最重要的故事的内容,就是通知了,我们需要把通知跟切点结合起来,我们要使用的通知者是: -->
<bean id="sleepHelperAdvisor" class="org.springframework.aop.support.DefaultPointcutAdvisor">
<property name="advice" ref="sleepHelper" />
<property name="pointcut" ref="spleepPointcut" />
</bean>
<!-- 切入点和通知都配置完成,接下来该调用ProxyFactoryBean产生代理对象了 -->
<!-- ProxyFactoryBean是一个代理,我们可以把它转换为proxyInterfaces中指定的实现该interface的代理对象: -->
<bean id="humanProxy" class="org.springframework.aop.framework.ProxyFactoryBean">
<property name="target" ref="human" />
<property name="interceptorNames" value="sleepHelperAdvisor" />
<property name="proxyInterfaces" value="com.test.aop.Sleepable" />
</bean>
</beans>
//实现接口
package com.test.aop;
public class Human implements Sleepable {
@Override
public void sleep() {
// TODO Auto-generated method stub
System.out.println("睡觉啦,哈哈");
}
}
//定义一个接口实现jdk代理
package com.test.aop;
public interface Sleepable {
void sleep();
}
//实现前后通知
package com.test.aop;
import Java.lang.reflect.Method;
import org.springframework.aop.AfterReturningAdvice;
import org.springframework.aop.MethodBeforeAdvice;
public class SleepHelper implements MethodBeforeAdvice,AfterReturningAdvice{
@Override
public void afterReturning(Object returnValue, Method method,
Object[] args, Object target) throws Throwable {
niaho();
}
@Override
public void before(Method method, Object[] args, Object target)
throws Throwable {
enen();
}
public void niaho(){
System.out.println("调用前,你应该做的是");
}
public void enen(){
System.out.println("调用后你应该做的事");
}
}
测试创建ioc容器
package com.test.aop;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class Tests {
public static void main(String[] args){
ApplicationContext appCtx = new ClassPathXmlApplicationContext("spring/applicationContext-aop1.xml");
Sleepable sleeper = (Sleepable)appCtx.getBean("humanProxy");
sleeper.sleep();
}
}
