spring的ProceedingJoinPoint如何串改参数？

我是这样写的

    public Object handle(ProceedingJoinPoint thisJoinPoint) throws Throwable {
        Object[] objects = thisJoinPoint.getArgs();
        for (int i = 0; i < objects.length; i++) {
            Object o = objects[i];
            String json = JSONObject.toJSONString(o);
            JSONObject data = JSONObject.parseObject(json);
            data.put("sex", 20);
            objects[i] = data;
        }
        System.out.println(JSONObject.toJSONString(objects));
        Object result = thisJoinPoint.proceed(objects);
        System.out.println(result);
        return result;
    }

这样data不是原来的那个Object类型。
