Using AspectJ project as a jar in other projects

问题:

Being new to AspectJ and Spring AOP, I have a Spring AOP project with Aspects defined in it. Pointcut is defined on annotation Loggable. Whenever a method with @Loggable is executed the advices should get executed.

Annotation:

@Target(ElementType.METHOD)
@Retention(RUNTIME)
public @interface Loggable {

    String customMessage() default "";

    String[] properties() default {};

    String type();
}

Below is the Aspect class:
LoggingAspect:

@Aspect
@Component
public class LoggingAspect {

    private final Logger LOGGER = Logger.getLogger(this.getClass());

    @Around("loggablePointcut(loggableAnnotation)")
    public Object beforeDebug(ProceedingJoinPoint joinpoint, Loggable loggableAnnotation) throws Throwable {
        final String logType = loggableAnnotation.type();

        LOGGER.log(Level.toLevel(logType), joinpoint.getSignature().toString() + " - " + loggableAnnotation.customMessage());
        System.out.println("in here");

        // Default Object that we can use to return to the consumer
        Object returnObject = null;

        try {
            returnObject = joinpoint.proceed();
        } catch (Throwable throwable) {
            throw throwable;
        }

        return returnObject;
    }

    @Pointcut("@annotation(loggableAnnotation)")
    public void loggablePointcut(Loggable loggableAnnotation) {
    }
}

Now to make the app runnable and testing once locally:
Application.java:

@SpringBootApplication
public class Application {

    @Loggable(type = "info")
    public void testing() throws NoSuchMethodException, SecurityException {
        System.out.println("testing");
    }

    public static void main(String[] args) throws NoSuchMethodException, SecurityException {
        ApplicationContext ctx = SpringApplication.run(Application.class, args);
        Application app = (Application) ctx.getBean("application");
        app.testing();
        System.err.println("Executed from project A");
    }
}

Till here everything works fine. Now my actual requirement is to use these aspects in my other spring boot projects. I read this article here, but couldn't seem to understand it.

I am confused with following questions:

Q1. How to export the AspectJ project as a jar in other projects? Do I right click and export it as jar and import the generated jar and everything will work? (I tried this but it didnt work)

Q2. Any other options I can use here?
