PROBLEMhata
bir sınıfta bir yöntemin yürütülmesi için bir pointcut oluşturma. Bu sınıf bir denetleyici sınıfıdır ve @Controller ek açıklama ile belirtilmiştir ve bu nedenle, bu yönüyle gerekli olan aynı şekilde hiçbir çekirdeğe gerek yoktur. Dağıtıcı sunucu kodu, görünüm ve denetleyici sınıfını ekliyorum. Birisi sorunun ne olduğunu tanımlayın.
