you can get method parameter and its value and if annotated with a annotation with following code:

Map annotatedParameterValue = getAnnotatedParameterValue(MethodSignature.class.cast(jp.getSignature()).getMethod(), jp.getArgs()); ....

private Map getAnnotatedParameterValue(Method method, Object[] args) {
        Map annotatedParameters = new HashMap<>();
        Annotation[][] parameterAnnotations = method.getParameterAnnotations();
        Parameter[] parameters = method.getParameters();

        int i = 0;
        for (Annotation[] annotations : parameterAnnotations) {
            Object arg = args[i];
            String name = parameters[i++].getDeclaringExecutable().getName();
            for (Annotation annotation : annotations) {
                if (annotation instanceof AuditExpose) {
                    annotatedParameters.put(name, arg);
                }
            }
        }
        return annotatedParameters;
    }
