        int i = 1/0;//异常
    }

import org.aspectj.lang.annotation.*;

/**

@Aspect

    //前置通知
    public void before(JoinPoint joinPoint){
        System.out.println("前置通知......" + joinPoint);
    }

    //后置通知
    public void afterReturing(Object result){
        System.out.println("后置通知=================="+result);
    }

    //环绕通知
    public Object around(ProceedingJoinPoint joinPoint) throws Throwable {
        System.out.println("环绕前通知================");
        // 执行目标方法
        Object obj = joinPoint.proceed();
        System.out.println("环绕后通知================");
        return obj;
    }

    //最终通知
    public void after(){

    }

    //异常抛出通知
    public void afterThrowing (Throwable e){
        System.out.println("异常抛出通知==============" + e.getMessage());
    }
