下面是代码

@Component
public class UserDaoImpl {
    public void add() {
//        int a=10/0;
        System.out.println("add");
    }
}

@Component
@Aspect
public class ProxyDemo{
    //最终通知
    @After(value = "execution(* com.nwl.demo2.UserDaoImpl.*(..))")
    public void after(){
        System.out.println("after.......");
    }
    //前置通知
    @Before(value = "execution(* com.nwl.demo2.UserDaoImpl.add(..))")
    public void before(){
        System.out.println("before.......");
    }
    //后置通知，当有异常时不执行
    @AfterReturning(value = "execution(* com.nwl.demo2.UserDaoImpl.add(..))")
    public void afterReturning(){
        System.out.println("afterReturning.......");
    }
    //异常通知，当有异常时执行
    @AfterThrowing(value = "execution(* com.nwl.demo2.UserDaoImpl.add(..))")
    public void afterThrowing(){
        System.out.println("afterThrowing.......");
    }
    //环绕通知
    @Around(value = "execution(* com.nwl.demo2.UserDaoImpl.add(..))")
    public void around(ProceedingJoinPoint proceedingJoinPoint) throws Throwable {
        System.out.println("Around前.......");
        proceedingJoinPoint.proceed();//调用被增强的方法
        System.out.println("Around后.......");
    }
}


public class Main {
    public static void main(String[] args) {
        ClassPathXmlApplicationContext applicationContext=new ClassPathXmlApplicationContext("bean2.xml");
        UserDaoImpl userDao = applicationContext.getBean("userDaoImpl",UserDaoImpl.class);
        userDao.add();
    }
}

报这个错的原因有两个
一个是execution(* com.nwl.demo2.UserDaoImpl.add(..))位置的类名不对
另外是导入的aspectj的jar包不对，可以多试几个版本
