请问各位关于0 formal unbound in pointcut

Question

这是一个service类：

package com.netease.course;

public class Service1 {
    public void add() {
        System.out.println("Service1:Add");
    }

    public void del() {
        System.out.println("Service1:Del");
    }
    public void check() {
        System.out.println("Service1:Check");
    }

    public void update() {
        System.out.println("Service1:Update");
    }
}

想在service类执行之前执行arithmeticDoLog函数可是最后会显示0 formal unbound in pointcut，请问应该如何解决啊！

@Aspect
public class LoggingAspect {
    @Before("execution(* com.netease.course.Caculator.*())")
    private void arithmeticDoLog(JoinPoint jp, int a) {
        System.out.println("abc");
    }
}

package com.netease.course;

import org.springframework.context.ApplicationContext;
import org.springframework.context.ConfigurableApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class TestAop {
    public static void main(String[] args) {
        ApplicationContext context = new ClassPathXmlApplicationContext("application-context.xml");

        Service1 service1 = context.getBean("service1", Service1.class);
        service1.add();
        service1.del();
        service1.getClass();
        ((ConfigurableApplicationContext) context).close();
    }
}

Answer 1

@Before("execution( com.netease.course.Caculator.())")
扫描的不对吧

表达式，和你的Service1没有关系呀
