Can we enable or disable Aspect based on value of any flag or through configuration file?

Question

I have added following dependency in pom.xml

            org.springframework

You may use enabling/disabling component with properties with ConditionalOnExpression annotation. When component is disabled the aspect is too.

@Component
@Aspect
@ConditionalOnExpression("${authentication.service.enabled:true}")// enabled by default
public class AuthenticationServiceAspect {
    @Before("execution(* com.service.impl.AuthenticationServiceImpl.*(..))")
    public void adviceMethod(JoinPoint joinPoint) {
        if(true){
            throw new Exception();
        }
    }
}

To disabling the aspect, just add authentication.service.enabled=false to your application.properties.
