Hier sind Klassen und XML-Konfiguration für Java/AspectJ-Demoprojekt, aber es schlägt fehl. Projekt ist in Eclipse gebaut. Ich suchte im Internet, fügte alle Bibliotheken hinzu, aber es schlägt immer noch fehl. Irgendeine Idee, was könnte falsch sein?AspectJ Der Verweis auf Bean 'selectAll' konnte nicht aufgelöst werden
UPDATE: Diese Klassen wurden hinzugefügt aspectj Projekt Eclipse: aopalliance.jar asm.jar aspectj.jar aspectjrt.jar aspectjtools.jar aspectjweaver.jar cglib.jar org.aspectj.matcher. jar

wurden diese Klassen hinzugefügt aspectj Projekt Eclipse: aopalliance.jar asm.jar aspectj.jar aspectjrt.jar aspectjtools.jar aspectjweaver.jar cglib.jar org.aspectj.matcher.jar –
I gerade verifiziert durch Ausführen von 'jar tf', dass die' org.aspectj.weaver.tools.PointcutPrimitive' Klasse in aspectjweaver.jar liegt, die du bereits erwähnt hast. Meine beste Theorie ist, dass es entweder durch die Eclipse-Konfiguration irgendwie nicht in den Klassenpfad der Laufzeit übergeht, oder dass es eine Versionskonflikt ist, so dass es sich um eine Version des JAR handelt, die die Klasse nicht wirklich enthält. –
Vermutlich nicht übereinstimmende Version oder beschädigte libm, weil ich beide (vorher) heruntergeladene Bibliotheken hatte und dann AJDT hinzugefügt habe (welches auch diese Bibliotheken hat). Wie auch immer, ich habe referenzierte Bibliotheken von Eclipse gelöscht, fügte sie zurück (nur von AJDT und jetzt funktioniert es. Danke! –
