【AOP】在Aspect中无法获取实现类方法的注解
问题
MethodSignature methodSignature = (MethodSignature) (joinPoint.getSignature()); Method method = methodSignature.getMethod(); CustomLog log = method.getAnnotation(CustomLog.class);
如果在实现类上进行注解,则 log 为null
解决方法
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);
