J'ai le comportement étrange suivant.@AfterThrowing au printemps comportement différent
Lorsque j'utilise une méthode nommé pointcut le conseillé court avant que le corps de la méthode @AfterThrowing
annoté. Mais si j'utilise un point-en-ligne, le @AfterThrowing
annoté est exécuté en premier.
Pourquoi donc?
Voici le code:
@Component
@Aspect
public class CustomAspect {
@AfterThrowing(pointcut = "execution(* throwAnException(..))", throwing = "exception")
public void adviceForExceptionThrowing(Exception exception) {
System.out.println("###### " + exception.getMessage() + " ######");
}
}
résultats dans:
INFO: Refreshing org.spring[email protected]5a10411: startup date [Wed Jun 14 15:51:26 EEST 2017]; root of context hierarchy
###### Some message from the exception ######
Exception in thread "main" java.lang.Exception: Some message from the exception
2ème résultat:
@Component
@Aspect
public class CustomAspect {
@Pointcut("execution(* throwAnException(..))")
private void pointcutForException() {
}
@AfterThrowing(pointcut = "pointcutForException()", throwing = "exception")
public void adviceForExceptionThrowing(Exception exception) {
System.out.println("###### " + exception.getMessage() + " ######");
}
}
Et nous obtenons:
INFO: Refreshing org.spring[email protected]5a10411: startup date [Wed Jun 14 15:54:38 EEST 2017]; root of context hierarchy
Exception in thread "main" java.lang.Exception: Some message from the exception
