Ich habe das folgende seltsame Verhalten.@AfterThrowing im Frühjahr unterschiedliches Verhalten
Wenn ich einen benannten Pointcut verwende, wird die empfohlene Methode vor dem Rumpf der @AfterThrowing
annotierten Methode ausgeführt. Aber wenn ich einen Inline-Pointcut verwende, wird zuerst die @AfterThrowing
-Annotation ausgeführt.
Warum so? Hier
ist der Code:
@Component
@Aspect
public class CustomAspect {
@AfterThrowing(pointcut = "execution(* throwAnException(..))", throwing = "exception")
public void adviceForExceptionThrowing(Exception exception) {
System.out.println("###### " + exception.getMessage() + " ######");
}
}
Ergebnisse in:
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
2. Ergebnis:
@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() + " ######");
}
}
Und wir bekommen:
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
