老师，为什么我这个输出有问题？

package com.imooc.spring.ioc.entity;
import org.springframework.stereotype.Component;
@Component
public class BookShop {
    public void sellingBooks(){
        System.out.println("卖出一本java基础书籍");
    }
}

package com.imooc.spring.ioc.entity;
import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.annotation.After;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.springframework.stereotype.Component;

@Aspect
public class MethodPro {
    @Before("execution(public * com.imooc..*.*(..))")
    public void preSales(JoinPoint joinPoint){
        System.out.println("=========售前服务============");
    }
    @After("execution(public * com.imooc..*.*(..))")
    public void afterSales(JoinPoint joinPoint){
        System.out.println("=========售后服务============");
    }
}
