【AOP】在Aspect中無法獲取實現類方法的注解

問題

MethodSignature methodSignature = (MethodSignature) (joinPoint.getSignature());
Method method = methodSignature.getMethod();

CustomLog log = method.getAnnotation(CustomLog.class);

 

如果在實現類上進行注解，則 log 為null

 

解決方法

MethodSignature methodSignature = (MethodSignature) (joinPoint.getSignature());
//Method method = methodSignature.getMethod();
Method method = joinPoint.getTarget().getClass().getDeclaredMethod(methodSignature.getName(), methodSignature.getMethod().getParameterTypes());

CustomLog log = method.getAnnotation(CustomLog.class);
