@Component @Aspect public class After{ @AfterReturning(pointcut="execution(* com..*.*(..))",returning="ret") public void doAfter(JoinPoint pjp,Object ret){ System.out,print("目标程序与aop程序执行后将最后执行,返回参数为:" + ret); } }
异常通知注解
@Component @Aspect public class ThrowException{ @AfterThrowing(pointcut = "execution(* com..*.*(..) )",throwing="e") public void doThrow(JoinPoint jp,Throwable e){ } }

@Component @Aspect public class Around{ @org.aspectj.lang.annotation.Around("execution(* com..*.*(..))") public String around(ProceedingJoinPoint pjp){ } }
