Why the Pointcut expression is not working

If i keep @Pointcut("within(org.example.ShoppingCart.*)") in AuthenticationAspect.java then the authenticate method is NOT getting invoked BUT when i change to @Pointcut("within(org.example..*)") then it does get invoked.

Doesn't the 2nd PointCut below automatically include the first one?

@Pointcut("within(org.example.ShoppingCart.*)")

@Pointcut("within(org.example..*)")

i believe both of these should work.

Following is the code :

ShoppingCart.java

package org.example;

import org.springframework.stereotype.Component;

@Component
public class ShoppingCart {
    public void checkout(String status)
    {
        System.out.println("Checkout method called");
    }
}

AuthenticationAspect.java

package org.example;

import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.aspectj.lang.annotation.Pointcut;
import org.springframework.stereotype.Component;

@Aspect
@Component
public class AuthenticationAspect {
    @Pointcut("within(org.example.ShoppingCart.*)")
    public void authenticationPointCut()
    {
    }

    @Before("authenticationPointCut()")
    public void authenticate()
    {
        System.out.println("Authentication is being performed");
    }
}

Main.java

package org.example;


import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.AnnotationConfigApplicationContext;

public class Main {
    public static void main(String[] args) {
        ApplicationContext context = new AnnotationConfigApplicationContext(BeanConfig.class);

        ShoppingCart cart = context.getBean(ShoppingCart.class);
        cart.checkout("CANCELLED");
    }
}

BeanConfig.java

package org.example;

import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.EnableAspectJAutoProxy;

@Configuration // Indicates this is a configuration class
@ComponentScan(basePackages = "org.example")   // Indicates where to find the components/beans
@EnableAspectJAutoProxy // Enables the AspectJ features in project
public class BeanConfig {

}

i am learning spring aspect and unsure why the pointcut expression is not working .

Since the within pointcut designator limits matching to join points of certain types, the problem is your pointcut expression is matching types within ShoppingCart because of .* in the end. If you remove those characters it should work.

@Pointcut("within(org.example.ShoppingCart)")
public void authenticationPointCut(){}
