It is up to the limiter implementation to determine if units from the past before the limiter was created or reset are available for use. If a limiter implemetation does not allow setting a duration, it must throw an UnsupportedOperationException when its setDuration() method is called.Method ...
RateLimiter 可以动态调整产生令牌的速率,但是这里涉及一个问题,如何处理当前被阻塞的请求以及后续请求?先看看官方的注释: /** * Updates the stable rate of this {@code RateLimiter}, that is, the {@code permitsPerSecond} * argument provided in the factory method that constructed the {@code RateLimit...

This is the rate limiter implementation found in theGuava libraries, extracted into its own project so that modifications could be made. The main modification made in this version of the rate limiter is the ability to set the max-burst-seconds property on theSmoothBurstyrate limiter. ...
Remove the need for any non-core-Java classes outside of the original RateLimiter and SmoothRateLimiter classes. Remove the need for a SleepingStopwatch or similar class instance. Guava provides rate limiters with either bursty or warm-up behavior. Throttle provides only a single strict rate lim...

The previously defined implementation works if Spring Cloud Gateway listens directly to the client’s request. However, if we deploy the application behind a proxy, all the host addresses will be the same. Therefore, the rate limiter will see all requests as coming from the same client and lim...
