基于Schema配置的AOP

一、切面配置

<aop:config proxy-target-class="true">
        <aop:pointcut id="pointcut" expression="target(NaiveWaiter) and execution(* greetTo(..))"/>
        <aop:aspect ref="aspect">
            <aop:before method="before" pointcut-ref="pointcut"/>
        </aop:aspect>
    </aop:config>

    <bean id="waiter" class="NaiveWaiter"/>
    <bean id="aspect" class="PreGreetingAspect"/>

proxy-target-class 为true时使用CGLib代理 false时使用JDK. 

环绕通知类需要注意

import org.aspectj.lang.ProceedingJoinPoint;
public class SurGreetingAspect {
    public Object sur(ProceedingJoinPoint pjd)throws Throwable {
        System.out.println("----------------");
        Object obj=pjd.proceed();

        return obj;
    }
}
