I see secondsUntilReset=904. I run code 1 hour later and get the same error message. I don't know why. Thanks for any help.
我明白了secondsUntilReset=904。我在 1 小时后运行代码并收到相同的错误消息。我不知道为什么。谢谢你的帮助。

There are rate limits in the Twitter API. You cannot call a given Twitter API endpoint more than a given number of times per 15 minutes (on behalf of the authencated user or not).
Twitter API 中存在速率限制。您每 15 分钟调用给定的 Twitter API 端点的次数不能超过给定的次数（无论是否代表经过身份验证的用户）。
What happened to you is that your code must have reached the rate limit very quickly (the endpoint to retrieve followers IDsis limited to 15 calls per 15 minutes for a given authenticated user) so you will have to wait (904 seconds) before trying again.
发生在您身上的是您的代码必须很快达到速率限制（对于给定的经过身份验证的用户，检索关注者 ID 的端点限制为每 15 分钟 15 次调用），因此您必须等待（904 秒）才能再次尝试.
Be careful to the Twitter API endpoints you are calling (through Twitter4J) in order to economize your API calls and thus avoid reaching the rate limit.
请注意您（通过 Twitter4J）调用的 Twitter API 端点，以节省您的 API 调用，从而避免达到速率限制。
For further informations, have a look at those resources on Twitter Developers, especially at its documentation:
有关更多信息，请查看Twitter Developers上的这些资源，尤其是其文档：
- REST API Rate Limiting in v1.1(general topic about rate limiting in the Twitter API)
- REST API v1.1 Limits per window by resource(rate limits for each endpoint)
- Error Codes and Responses(which explains to you what is your '
88' response code).
- v1.1 中的 REST API 速率限制（关于 Twitter API 中速率限制的一般主题）
- REST API v1.1 按资源限制每个窗口（每个端点的速率限制）
- 错误代码和响应（它向您解释了您的“
88”响应代码是什么）。

You dont have to wait to fix rate limit issue. If you have many tokens corresponding different twitter accounts, then you can renew your current used token, right. Think about the big picture. Let's say that you have 25 different accounts(tokens) in a list or array object, and you are getting one of them each time that you have a rate limit issue. Then when you reach to the last item in list token list, then you can refill this list with these 25 token accounts, right. The beauty is this, if you have good enough number of accounts(tokens), each refilling loop, the system automatically will be waited to recover the used accounts, so you will not have to worry about the rate limit and your application will never stop because of rate limit issue. I have already implemented this mechanism in my project and it works perfect. This is the only best solution.
您不必等待修复速率限制问题。如果你有很多代币对应不同的推特账号，那么你可以更新你当前使用的代币，对吧。想想大局。假设您在一个列表或数组对象中有 25 个不同的帐户（令牌），并且每次遇到速率限制问题时都会获得其中一个。然后当你到达列表令牌列表中的最后一项时，你可以用这25个令牌帐户重新填充此列表，对。美妙之处在于，如果您有足够数量的账户（代币），每次充值循环，系统会自动等待恢复使用的账户，因此您不必担心速率限制，您的应用程序永不停止因为速率限制问题。我已经在我的项目中实现了这个机制，而且效果很好。
