Hier ist mein Projekt: https://github.com/intrade/inventory Ich versuche Frühling Sicherheit zu aktivieren Java-config und wenn ich versuche, eine Abhängigkeit vom Typ erhalten MyCustomUserDetailsService in my SecurityConfig class i eine Ausnahme zu injizieren:

Vielen Dank im Voraus!

Answer 1

Sie versuchen, Ihren Benutzer-Details-Dienst nach Klasse zu senden, aber das kann nicht funktionieren, da die Spring-Bean tatsächlich ein Proxy ist, der um diese Klasse herum erstellt wurde (und keine Instanz der Klasse). Der Proxy wird jedoch alle Schnittstellen der Original-Bean implementieren, sodass das Injizieren über die Schnittstelle sicher ist.

Tauschen Sie dieser Linie:

@Autowired 
private MyCustomUserDetailsService myCustomUserDetailsService; 

für diese:

@Autowired 
private UserDetailsService myCustomUserDetailsService; 

Lesen Sie den Abschnitt über Proxying Mechanisms im Frühjahr AOP die Details zu verstehen.
